The existing waterproofing had failed due to a previous poor installation, the result of which saturated the insulation below the exterior roofing. New high performance solutions were specified that included a range of IKO roofing waterproofing systems to protect both the flat and pitched roofing areas of the building. IKOslate, a robust and durable tile was specified for the pitched roof due to vandalism and the fragility of the current system, whereas a tapered scheme was required for the flat roofing - IKO Ultra Prevent alongside a cold applied liquid solution (IKO Polimar) for the more intricate details.

The project was to refurbish the roof and improve the drainage and insulation and bring it up to current building control standards. A thermographic survey of the roof was carried out by IKO, which confirmed that it was sound enough to have an overlay of IKO UXPL bituminous membrane rather than stripping it back and rebuilding. IKO UPXL was primarily chosen by the client for the 30 year guarantee. One section of the roof to be repaired was on top of dormers. Flame-free IKO UPXL membranes were used because of the potential fire risk of the abutting pitched tiled roof.

The appearance of the current cladding was in need of improvement and with the client requiring a specific colour, IKO were approached. IKO Polimar CRS was chosen as it ticked all the relevant boxes for the client – a single coat repair system that provide a tough, durable finish with excellent erosion, weather and UV resistance and a 10 year material guarantee.

IKO Permatec, developed by IKO PLC, is a highly advanced and innovative hot melt waterproofing system, which provides environmental benefits as well as market leading performance. Providing zero wrapper waste, lower application temperatures and anti-root protection, the product provides many operational advantages. It is also manufactured in the UK, with a dramatically lower carbon footprint than imported systems.

BriefAs part of the drive to revitalise Kirkby Town Centre, the local authority, Knowsley Metropolitan Borough Council, has been significantly investing in regeneration works. A redundant B&M shopping centre formed an important part of the uplift.At 36,000 sq ft, the empty precinct was the largest vacant unit in the town centre and was in need of significant repair and modernisation. Bringing the building up to date was crucial in encouraging businesses back to the area and delivering more choice of retail outlets to visitors.The project was estimated to cost £1.66million, with £450,000 allocated to the roof renovation, which was to be carried out by Paramount Roofing Systems, in association with IKO.ChallengesThe busy, central location of the shopping centre presented several challenges for the roof installation. The existing roof needed a comprehensive refurbishment, including stripping back to the metal decking and removal of all layers and outdated materials.A total of 48 redundant skylights needed to be carefully and meticulously taken out as they were no longer needed or functional. Any obsolete ventilation fans and plant equipment also had to be removed, as streamlining roof space was essential for efficiency. This all had to take place before the installation commenced.When it came to delivery of materials, there was limited laydown due to the surrounding live loading bays for neighbouring shops and this lack of space also affected the storage of the materials on-site.Inclement weather presented a significant challenge for the team. Despite operations taking place during the summer, torrential downpours were frequent. Protecting the integrity of the building was paramount to ensure the businesses below the installation could continue trading without risk of water ingress or leaks.SolutionAs this was such an expansive project, it was important that the roofing system was robust, easy to install and would stand the test of time. IKO worked with Paramount Roofing Systems to ensure the most suitable solution was specified for the replacement roof.A fully built-up bituminous felt warm roof was chosen as the best option, as it was designed to ensure effective insulation, weatherproofing and longevity for many years to come.To mitigate disruption to nearby trade, Paramount Roofing Systems effectively coordinated with local businesses for the duration of the project. The team established a robust schedule, so that construction activity was minimally affected by the town centre’s busy hours and zoned time restrictions.A telescopic forklift truck was hired specifically for the project, to handle offloading and loading more efficiently and allow the team to move more precisely within the confined space. Four operatives were trained to ensure that the forklift truck was used safely, which was imperative given the high footfall close to the site.IKO arranged for bulk materials to be delivered directly to the roof to help overcome the issue of restricted space. Materials were also stored off-ground and covered at all times with strategically placed tarpaulins to avoid water damage from the persistent rain.Despite the wet weather conditions hindering progress, the project was delivered just over the expected time frame of 8-10 weeks. The collaboration between IKO and Paramount Roofing Systems was pivotal in ensuring that the project met and exceeded requirements – contributing to an integral building that promises to give a much-needed boost to Kirkby town centre.

When Westminster Cathedral’s roof was first asphalted back in 1903, it would have utilised naturally occurring asphalt deposits dug up from an overseas lake. These days, things are done a little differently. Instead, IKO’s Permaphalt – a polymer modified mastic asphalt – was specified for the extensive reroofing of the Cathedral by Architect, Michael Drury from St Ann’s Gate Architects. “Asphalt had worked well for the Cathedral in the past and there was no reason why it shouldn’t again,” he said, adding the new roofing’s 25 year guarantee clinched the decision for a like-for-like replacement.

The roof on Bede Primary School and Community Centre in Gateshead was in great need of repair. Installing roofing contractors Hodgson and Allon liaised with IKO to refine the specification to meet the client’s requirements. This included a full strip and re-cover with a flame free system to carry a 20 year guarantee. IKO chose an IKO Mach One single layer bituminous system incorporating a site specific cut-to-fall system. This project was a complex roof replacement system with multi-trades required for specialist operations.

Dublin City Council were particularly interested in IKO Carrara’s exceptional environmental properties with its view to adding photovoltaic panels (PV) to the existing building. PV panels in combination with IKO Carrara have greater efficiency, up to 25%, as the performance of the solar cells increases during sunny periods, at a lower ambient temperature.

IKO Polymeric, SIG Design & Technology, and Excel Roofing Services have collaborated to design, supply and install 250m2 of single ply roofing for the new kiosk, glass covered beach walkways and stores which houses the latest Oceanarium residents, ten Humboldt Penguins.

Project descriptionDixons Academies Trust is a well-established multi-academy trust that aims to challenge educational and social disadvantage in Yorkshire and the North West.The trust transforms schools into safe and high-performing learning environments, enabling students from all backgrounds to realise their potential and maximise their opportunities after school.Alpha Roofing Systems was brought in to refurbish two roof areas at Dixons Croxteth Academy in Liverpool after the existing waterproofing failed.A number of complex challenges arose from the start; after stripping back the aged and failed single ply system, Alpha identified a water-saturated bituminous roof beneath, which also overlaid the original asphalt waterproofing.The excess weight imposed on the roof from the multiple, heavily saturated waterproofing systems led to cracking and depressions in the deck, as well as rusting of reinforcement within the structure.This meant that, before installation work could even begin, many hours of labour were required to remove the top two waterproofing layers to expose the original asphalt. What’s more, this work had to be undertaken both during term time and a period of heavy rainfall.Solution and installationAfter close consultation with their IKO business manager, Mark Taylor, the Alpha team selected the IKO ULTRA Prevent 25 waterproofing system for this project.To adhere to Department of Education requirements, a 35-year durability statement was necessary, so the long-lasting, durable finish offered by the IKO ULTRA Prevent system was ideal.Challenges continued to come thick and fast throughout the project; after stripping the roof back to the asphalt waterproofing, a large expansion joint was found near the clerestory window. Tapered designs were subsequently adjusted to accommodate.30 tonnes of waste material – primarily due to the uplift of the previous failed waterproofing systems – also had to be removed from the roof over the course of a week.Furthermore, complex design variables meant that Alpha could not fully determine the existing roof falls until the roof had been sufficiently exposed. Working closely with the IKO technical team, design information and solutions were identified to keep the project on track.To complicate matters further, Alpha was also required to carry out this extensive work during active teaching time. This presented not only additional health & safety considerations but also the need to minimise disruption.With a stringent construction phase plan and regular active monitoring, the project was completed with a zero incident/accident rate and excellent feedback from the client on Alpha’s approach to safety.Despite a number of hurdles and complexities to overcome, Alpha Roofing Systems delivered the project ahead of time and within budget, providing a low maintenance, long-lasting roof for Dixons Croxteth Academy and a satisfying outcome for all involved.

No timber was allowed as part of the new refurb to conform to FM Global (Airbus Insurers) regarding system fire rating. IKO recommended an overlay on the existing deck, which complied with all the latest British Standards and Regulations. IKO Mach One System was chosen as it provided a flame-free System. Where detailing was difficult IKO Polimar EC/UV System was used. The roof refurbishment also included the installation of smoke vents, associated smoke control panels and accessories.

Sandbanks Court apartments are situated within the expensive up-market area of the Dorset coastal peninsular and enjoy spectacular panoramic views across the sea. A green roof system was selected for this project as the client required a roof that would complement and accommodate the step in levels to follow timber decking lines to the 55m² roof terrace areas. IKO Single Ply’s Spectraplan SM120 light grey single ply waterproofing system was overlaid to the existing roof and newly built sun rooms, ready to receive a green roof system.

In 2014 discussions took place between IKO and Architect for the property, over the possibility of renewing the mastic asphalt roof coverings with an IKO Permaphalt Polymer Modified Mastic Asphalt System. During 2015 this process took place with the work being undertaken by Knight Asphalte, one of IKO’s Approved Contractors. During the works some 35 tonne of IKO Permaphalt was installed and due to IKO’s commitment of supplying Carbon Neutral Mastic Asphalt we are able to calculate the impact this has on the population.

A detailed visual and physical inspection, together with core and moisture probe analysis carried out by IKO on the roof, patio and walkway areas, indicated that the waterproofing membrane was in a condition commensurate with the age and the type of the traditional membranes installed. They had become fragile and brittle. The decks were saturated due to water ingress, and natural ageing had played a principle part in the deterioration of the waterproofing system. The build-up would not have met the requirements of the current building regulations Part L. IKO worked to refine the specification for the main roof,

Along with re-surfacing, inspection, showed signs of wear and tear on the bridge surface areas too. Consulting Engineers, Jacobs, approached IKO for the specification, and Galliford Try won the tender. BriggsAmasco were chosen as the installing contractor. IKO’s Permatrack Bridge Surfacing system was chosen - a waterproof mastic asphalt wearing course for Bridge Decks containing both polymer and epure (Trinidad Lake Asphalt) modifications to the bitumen binder, which offers improved material flexibility and maintains good rut resistance. Existing mastic asphalt surfacing and bridge deck waterproofing was stripped off and replaced with Stirling Lloyd’s eliminator waterproofing system and Permatrack.

IKO Polimar FCS is a high performance cold applied, two part, fast curing waterproofing system was a perfect solution for this project as it cured within 20 minutes. Also, being a self-levelling and slip resistant product, it enabled residents to come and go within minutes of it being applied.

The 55,000m2 roof area of one of London's busiest train stations was in an advanced stage of deterioration. IKO PLC liaised with roofing contractors Weatherproofing Advisors to refine the specification. Working with the public, and in a commuter environment, Weatherproofing Advisors had the added challenge of completing the project through one of the worst winters in 50+ years.

Hundreds of homes have been refurbished as part of a multi-million pound revamp of housing association properties.Tristar Homes spent £8m on the scheme at Kennedy Gardens in Billingham where they carried out work on 225 properties across the three housing blocks as well as creating 12 new one and two bedroom homes which have been made available for rent.The development, completed in September 2014, includes the fitting of new windows, new bathrooms and improved living space due to the new balcony extensions.The roof area before its refurbishment had a U-value of 0.4 W/m²K. This existing build-up would not have met the requirements of the current building regulations Part L.The lower roof had been overlaid at least twice since its original construction. In all but one core sample, the existing insulation was wet through and therefore it was apparent that 90% of the existing roof build up needed stripping to the original asphalt. A further inspection was needed when the asphalt was exposed to ascertain the condition and depth of the asphalt. The asphalt was deemed in reasonable condition so the new system could be installed onto the original asphalt.IKO worked with installing contractors BriggsAmasco to refine the roof specification and recommended IKO Mach One single layer bituminous membrane system, installed to the recommendations of wind uplift calculations and performing to a 0.18U value as per requirements.IKO Mach One membranes are a robust, flame-free, single-layer roofing system with added fire-retardancy. IKO Mach One can be mechanically fastened, ballasted or bonded with polyurethane adhesive.A 20-year insurance-backedfire retardancy guarantee was issued to cover all materials, design and workmanship covering contractor insolvency.

The Grade I listed Round Tower (dating from the 1400’s) is a fortification at the entrance to Portsmouth harbour it overhangs the Portsmouth sea front making it susceptible to coastal weather. It’s current waterproofing system needed replacing, The IKO Permaphalt System was chosen due to the 20 year guarantee it offered and the previous heritage projects IKO have successfully helped preserve with various waterproof solutions. Existing coverings were removed and replaced by Southern Flat Roofing & Pitched Roofing Ltd, providing a surface that would withstand constant foot traffic as well as the weather that many seafront structures suffer from.

Modern materials were employed in the quest to recreate part of Bristol’s heritage. SIG Design & Technology supplied IKO’s Armourplan PSG single ply membrane because it fitted the bill perfectly as the roof covering was ideal for replicating the original seamed lead roof.

BriefDorset House sits at the heart of Talbot Campus, where most of the undergraduate and postgraduate courses are delivered at Bournemouth University. It is home to the Doctoral College, providing important support to its postgraduate research community with a range of high-tech laboratory equipment, as well as the Business School’s Professional Engagement Suite.Sustainability is a top priority for Bournemouth University. In fact, the University is ranked 21st in the world and 6th in the UK for its contribution to UN Sustainable Goal 13: Climate Action for The Times Higher Education Impact Rankings 2023. As well as opening new eco-friendly buildings, Bournemouth University is carrying out major refurbishment works across its campuses, investing in a range of low or zero-carbon technologies to help minimise water and energy use.As part of this refurbishment, Dorset House was to undergo a significant transformation to help enhance the entrance area and make better use of the space. Bluestone Design & Construction Ltd was tasked with upgrading the building’s flat roofing system, in association with IKO, and the build-up include the installation of a new 80kWp solar PV system.ChallengesThere were several challenges to overcome during the project, but as the team had recently completed similar works on the nearby Poole House on campus, they could apply their extensive learnings to ensure the refurbishment of Dorset House ran seamlessly. As the project was on a busy campus, it was important that it was carried out during the holidays to avoid significant disruption to students and staff. There was, however, a short period during term-time that required more coordination, to ensure appropriate access while making sure the project ran on time.Another challenge was ensuring the material deliveries arrived on time, to minimise site storage issues and meet workforce scheduling requirements. The team managed this effectively, by ordering the materials via construction product distributor, SIG, which were then delivered as required from the local SIG depot. This meant Bluestone Design & Construction could meet programme deadlines, without needing to store materials long-term on-site.SolutionThe installation process at Dorset House involved a standard hybrid built-up roofing (BUR) system, using both self-adhesive and torch-on membranes suitable for the substrates of the project. Choosing products with a 25-year guarantee was important to the team, as the installation included solar electricity panels (also known as PV), that would need to provide reliable power output over the system’s lifespan.Bluestone Design & Construction followed a thorough process to ensure the roof area was suitable for the PV installation, following the necessary remedial works and new roof overlay. Once the systems were in place, all works were reviewed to ensure they met the specifications of an IKO technical engineer and requirements of IKO’s guarantee, without any issues. The team also worked to all the necessary health and safety standards throughout the project.Bluestone Design & Construction and IKO worked together to ensure that the Dorset House project was carried out within the programme requirements – finishing ahead of schedule, in September 2023. It was essential that the building was ready on-time and within budget, ahead of the installation of the new PV system, to ensure maximum availability for the 2024 period. With Bournemouth University’s ambitious sustainability targets in mind, the Bluestone Design & Construction team wanted the system to be fully operational as soon as possible. As the main contractor and roofing installer, Bluestone Design & Construction was able to have more control over the project and ensure the roofing segment ran smoothly as part of the wider picture.The University was extremely pleased with the installation and execution of the project. Now with its improvements made, Dorset House is another success story in the University’s plan to futureproof its campuses for many years to come.

Perry Hall Academy, a large primary school built in 1949, with original waterproofing still in-situ. IKO assisted the Academy funding bid by providing a detailed survey report, including intrusive core sample analysis. The roofs were suffering from water ingress, cracks in the mastic asphalt, pooled water and poor heat retention, so decision was made to replace the roofs throughout. New rooflights were also specified to allow more natural light in while the design chosen reduced the external noise transmission. IKO worked with specifier Concept Education Services to deliver the project (some work during term-time) within 6 months.

The roof to a Waitrose distribution centre has been completely refurbished in a single ply membrane system chosen for its sustainable credentials and no disruption to the retailer’s 24/7 operations at Aylesford near Maidstone, Kent. Supplied by SIG Design and Technology, 10,200m2 of IKO’s Spectraplan single ply membrane was specified for its ability to contribute to a BREEAM Very Good rating for the project which is in line with Waitrose’s mission to ‘tread lightly on the environment’.

In less than four months, SIG Design & Technology, IKO Polymeric and FK Group have completed a 48,000m2 roofing project for one of the biggest online grocery centres in the world. An incredibly tight programme minimised material waste and time on site, thanks to a number of innovations developed specifically for the project by the three businesses working collaboratively.

When Make Architects needed a waterproofing solution for their latest project in the City of London they turned to IKO PermaTEC hot melt. Waterproofing such an expansive and complex roof has its particular challenges and required robust and reliable detailing. The choice of waterproofing was to perform for a minimum of 30 years, be cost effective and also contribute towards the building’s design stage BREEAM Excellent rating.

Project descriptionTouchwood Shopping Centre in Solihull, Birmingham is an award-winning, 650,000 square-foot shopping and entertainment complex, which opened its doors in September 2001.Touchwood has become a blueprint for in-town development due to its innovative design, easy access to the M42, and 1,700 car parking spaces. It is home to more than 80 stores, 20 bars and restaurants, and a 9-screen cinema.The centre has successfully improved neighbouring facilities with malls, a retail offering, and civic gardens, providing green spaces for the local community.Rio Asphalt and Paving Co Ltd worked closely with the shopping centre management team to offer a replacement waterproofing and paving element for the 900m2 service deck area.Solution and installationThe focus was on delivering a solution that worked for both client and the tenants and ensured a smooth and seamless experience.IKO Permapark – a specially formulated mastic asphalt surfacing and waterproofing system for car parks and elevated vehicle decks – and the fast-curing IKO flexia metatech liquid waterproofing were chosen as the most suitable solutions for the project, given their durability and rapid installation capabilities.Certain areas were prioritised by the management team and project works were phased. The deck was split into manageable sections, which helped to minimise disruption and limit the impact on those occupying and visiting the site during the project period.Particular attention was given to the mechanical and electrical (M&E) services, which remained operational throughout the works. As areas were inaccessible for mastic asphalt, a compatible cold applied system was used instead.This enabled the works to dovetail into a small number of inaccessible areas, refurbishing what would have either been left or required substantial financial outlay and risk.The service deck area, which remained in use during the project, operated a one-way system for all vehicles. Rio also took measures to maintain road access around the centre and provided temporary delivery areas to assist with the distribution of goods to the stores.

A failed manhole near a residential area in Market Harborough needed to be reinstated. Leicestershire County Council required a long-lasting road ironwork reinstatement solution that could be installed right first time.

SIG Design & Technology and SIG Insulation are working with the Interserve Kajima consortium on a batch of seven secondary school projects to deliver a value-engineered, robust roofing solution. At Stopsley High School there are two roofs installed by Briggs Amasco in an approximate 16 week programme. The largest roof measures some 2500m2 and the inverted roof build up selected and supplied by SIG comprises IKO’s PermaTEC hot melt waterproofing system.

stunning new ‘brown roof’ is the crowning glory for a private dwelling overlooking the River Tweed. The project has been designed to last 100 years and takes into account the requirements of future generations of the family. The house is the first to be constructed in the UK with zero heating requirements using the mass timber Brettstapel technique. Passive technologies such as orientation for daylight and solar gain, super insulation and air-tightness levels have been utilised in order to achieve the internationally recognised Passivhaus standard.

SIG plc has worked closely with Wates Group for a number of years, supporting the main contractor on major construction projects up and down the country. The relationship between the two companies is one that goes beyond what would normally be expected, with Wates relying on SIG for more than just the supply of key construction products. Wates rather draws on the expertise and technical knowledge of the teams at SIG to identify innovative solutions which deliver cost-savings and performance improvements wherever possible.

Spectraplan has provided an innovative roofing solution for a major refurbishment to the newly named, Jack Jones House in Liverpool. Designed and built in the 1970’s, Jack Jones House (formerly Transport House) has been totally refurbished and renamed for Unite, the trade union. Jack Jones was the former leader of the TGWU, the Transport and General Workers’ Union.

The brief was to replace an existing roof that had reached the end of its serviceable life, with a high performance waterproofing solution and upgrade the insulation in order to meet the University’s energy efficiency policy.

One of the roofs within the scheme, Hodge Clough School in Oldham, had fallen into a dilapidated state of disrepair and was in great need of replacement. Council building surveyors came up with the appropriate specification and project managed the scheme to completion. The majority of the much-needed work took place at the school over the summer holidays in order to minimise disruption to the teaching programme, a major consideration for roofing works at schools, colleges and universities.

IKOpro Acrylic Roof Coat has been used to provide a quick (taking only 4 days to complete) and seamless waterproof solution to a leaking roof at Bellman’s Auctioneers & Valuers in West Sussex. Contracts Manager for M Holmes Construction (contractor) admits that it was much less labour intensive than traditional roof refurbishments. He said, “The beauty of this system is that you don’t have to re deck the roof, unlike some alternative liquid systems. So this means you save one day of labour, typically four men on a job this size, plus material costs.”
