ABG blueroof - Biodiverse & decking, 160 Old Street, London, UK
ABG
The former Royal Mail owned building at 160 Old Street, London, utilises 'blue roof' SuDS attenuation and biodiverse roofs and/or composite decking, retrofitted on 16 out of 29 different roof zones across multiple levels.The ABG blueroof system was specified to slow surface water run-off during key extreme rainfall events, in line with planning consent requirements for the provision of SuDS. The roof level storm water attenuation system was deemed the most cost-effective solution for the restricted urban site and avoided the need for an expensive and carbon intensive basement attenuation tank.
ABG blueroof - Green Biodiverse, Moreland Primary School, Islington, UK
ABG
Moreland Primary School is a purpose built school, nursery and Children's Centre requiring a multipurpose usable outdoor space.
Due to lack of space, the ground attenuation tanks planned would reduce site storage and limit access to other trades, therefore delaying the project, The challenge was to develop a storage/discharge system which wouldn't impact the project and be sensitive to the local biodiversity action plan.
ABG designed a versatile Blue Roof System removing the need for attenuation tanks and allowing the roof finishes required. ABG bio-diverse roof system helped maximise the BREEAM credits laid out in the action plan
ABG blueroof - Green Extensive & Paved Areas, 1 Charter Square, Sheffield, UK
ABG
The new six storey HSBC building at No.1 Charter Square in Sheffield utilises ABG’s blueroof system to meet the National Planning Policy Framework and the site's Flood Risk Management Policy. Attenuation for the building is provided at roof and street level, comprising void formers constructed within the roof and streel level structures to temporarily attenuate storm water, before gradually releasing it over a number of hours via the ABG restrictor chambers.At street level the system was installed underneath the surrounding walkways and access routes to restrict discharge rates at ground level, including a large landscaped podium deck area above a service yard where heavy duty void formers were used in the event emergency vehicle access is required.
ABG blueroof - Green Extensive, Huddersfield University, UK
ABG
The design in this project was to have a Green Roof and warm roof system The aim was to place standard green roofs which retains water but allows most of the rainfall to run into buried SuDS tanks.
Following consultation with ABG the design was changed to the ABG Blueroof system. The primary advantage of the system is that utilising the roof construction for water storage reduced the need for underground attenuation tanks. The simplicity of the design allowed for attenuation capacity and green roof installation at the same time saving the client time and money.
ABG blueroof - Green Extensive, Rathbone Market, London, UK
ABG
The designer obtained consent under the latest SuDS regulations in the densely build area of London. Restriction on outflow rates to sewers demanded high attenuation. The original design for stormwater attenuation involved discharging tanks under the ground. This was expensive and took up valuable space, an alternative was required.
ABG proposed their Blueroof system which could be installed directly on to the hot melt waterproofing system allowing various surface finishes. Due to height limitations a cascade system was used. Various roof finishes included paved access, landscaped areas and bio diverse to attract wildlife. This increased the potential for BREEAM points.
Erosion Control, Flood Embankment, Erosamat, Greatham, Hartlepool
ABG
The Greatham Managed Realignment Scheme was part of the Environment Agencies wider " Tees tidal Flood Risk Management Strategy" which imposed a legal requirement upon the Environment Agency to deliver intertidal habitats as compensation for the impact of flood management projects. The challenge was to construct embankments comprising predominantly of site won material.
THe size, scale and nature of the works dictates a tight time scale was maintained to ensure rapid return to its natural state. ABGs Erosamat Type 3 was chose, comprising 3 dimensional structure and entangled filaments. Erosamat forms a permanent composite with the natural vegetative root structure supported.
Green Roof Extensive, Leeds Skelton Lake Services, UK
ABG
Despite the challenges posed by completing construction and opening during the first lockdown, the new Skelton Lake Motorway Services project opened in March 2020 as planned, providing essential services to hauliers and key workers travelling during the start of the pandemic. The project incorporates an extensive green roof build-up to minimise the visual and physical impacts of the development on the surrounding country park and to enhance the biodiversity of the project.The wildflower green roof design provides multiple environmental benefits; including provision of a new habitat for local insect and bird life, helping to lower the site’s carbon emissions by absorbing heat emitted from the building into the cooler roof surface - reducing the air conditioning demand in the summer months. The green roof build-up also provides a level of insulation against heat loss in winter.
Green Roof, Biodiverse, Regent Street, Piccadilly, London, UK
ABG
The Green Roofs Consultancy report looked to the provision of Green Bio diverse roof to address the need to encourage additional species.
The ABG Green Bio diverse Roof System includes a mixture of plug planted sedum, cuttings and seeded annual and perennial wildflowers.
ABG Roofdrain was used as a reservoir and drainage base layer to optimise water retention and prevent ponding. Special provisions were made to create hibernicula for local endangered species. The roof will benefit the building by providing additional insulation and reducing noise pollution.The roofs substrate filters out dust and pollutants helping improve the environment nearby
Green Roof, Extensive, Alder Hey Children's Hospital, Liverpool, UK
ABG
The challenge was to incorporate a green roof finish both flat and curved to the roof areas. The roof pitch being as steep as 45 degrees in places, a pitch not conducive with a green roof system. ABG used their expertise in green roof and slope stabilisation to make the curved green roof possible. The system incorporated a series of anchor points, reinforcement geogrid (Trigrid), and geocellular technology (Erosaweb) to retain growing medium on each roof. The Green Roof system incorporates a SMART rain sensor and automated irrigation pipe system with each finger haveving its own dedicated mains operated tank
Retaining Wall, Webwall, Doune Castle, Stirlingshire, UK
ABG
The thirteenth century medieval stronghold Doune Castle, used as a filming location for Game of Thrones and Monty Python and the Holy Grail, was subject to a maintenance programme designed to improve the path network surrounding the castle. Celtic Historic Environment Scotland wanted to introduce a new stepped ramp from the main entrance road up to the Doune village footpath.The new elevation of this ramp required ABG Webwall as a curved solution that minimises the footprint of the slope compared to a stone alternative and blends in with the woodland surroundings. Webwall also provided a less carbon intensive option to hard landscaping materials.
Retaining Wall, Webwall, Westfield, Pembrokeshire, UK
ABG
The challenge was to mitigate the impact improvements would have on the nature reserve and to promote biodiversity to the former railway route
Retaining walls were needed to reduce the gradient of descent used by cyclists and walkers to allow accessibility for less able users.
ABG proposed using a Webwall fascia reinforced using Trigrid EX and include structural drainage provided by Fildrain. Webwall uses site won material in the cellular structure reducing the need for imported aggregate. Trigrid EX promotes interlock with the fill providing reinforcement whilst the FIldrain controls groundwater pressures. Webwall was seeded to provide pleasing biodiverse fascia.
Stabilisation - Abweb and Abgrid, Quarry Bank Mill, Styal, Cheshire, UK
ABG
Quarry Bank is an old cotton mill in Cheshire, now operated by the National Trust it attracts large numbers of visitors daily.
A permeable run off was required to allow the car park to be used without issue all year around as there had been problems with saturation previously.
A solution was required without having to replace the first lift of soil that was already down.
To stabilise the soft spots, Abweb back filled with the existing cappings meant further excavation was not required. Abgrid and Trigrid enabled the target CBR to be met with 30% less sub base needed.
Stabilisation - Sudsweb, Abgrid & Terrex, Devour, Holmfirth, UK
ABG
In 2017 permission was granted for the redevelopment of an historic abandoned mill in Holmfirth into a restaurant and cookery school.
It was soon clear the ground to be used for parking needed stabilisation.
To completely dig out the area would have been costly and there was little time for unplanned work.
ABG offered a stabilisation combination. Terrex SNW geotextile layer replaced the 50mm sand binding.
Abgrid was used as a basel stiffening layer and Sudsweb tied to the grid with Abfix ties.
Stone was then compacted ready for ABG permeable paving (see SuDS permeable paving Sudspave, Devour, Holmfirth)
SuDS Permeable Paving - Attenuation Car Park, Sudspave, Devour, Holmfirth, UK
ABG
In 2017 permission was granted for the re-devlopment of an abandoned mill in Holmfirth into a cookery school and restaurant.
The design required the car park to look as natural as possible but to withstand the manoeuvring of large delivery vehicles.
ABG offered a re-engineered solution showing that a porous type 3 attenuation stone over the whole car park removed the need for expensive attenuation tanks.
The main car park was covered in Sudspave interlocking pavers coloured to match the gravel. Truckcell was used for the turning area and filled with the same gravel for a natural finish.
SuDS Permeable Paving - Crane Hardstandings, Truckcell, Wadlow Wind Farm, Cambridgshire, UK
ABG
In Line with Cambridge County Councils renewable Energy Development Programme. RES received consent to build the 13 turbine Wadlow Wind Farm.
The site is in a sensitive ecological and archaeological location. It therefore meant the crane hard standings had to be sympathetic to the local environment without compromising the minimum bearing capacity of 200kpa.
ABG Truckcell Porous Plastic Paving System was chosen. This was supported by a free draining sub base and seeded with an indigenous seed mix to blend with the local environment.
Due to the rapid installation, grassed appearance and load bearing abilities Truckcell ticked all the boxes.

ABG
Quarry Bank MIll is an old cotton mill. Now operated by the National Trust it attracts large numbers of visitors daily to its attrections.
The overflow car park quickly turns to mud currently being fit for purpose fields. A permeable surface was required however to allow for a permeable surface large tanks would be needed to store rain water infiltration.
ABG Sudspave was chosen to provide a permeable surface and allow water to infiltrate.
Sudspave can be quickly and easily installed and cut to size on site. Sudspave can be finished with either gravel or grass for a natural finish.
SuDS Permeable Paving, Heatherwood Hospital, Ascot, UK
ABG
The newly redeveloped Heatherwood Hospital employs a total of 4,200m² of Sudsgrid 40 cellular pavers, filled with free-draining angular aggregate to provide 450 new parking spaces, delineated by yellow markers. ABG’s sub-base design utilises the unique Abgrid geogrid to reduce the thickness of DoT Type 3 stone required for structural stability, and through the use of the ABG Terrex NW non-woven geotextile layer, an additional stage of treatment was provided for the infiltrating water.ABG’s permeable paving limits surface water run-off and minimises the risk of localised flooding, alongside, providing a shallower construction profile. Resulting in reductions in site excavation, off-site tipping, DoT Type 3 stone deliveries and the associated costs.
SuDS Permeable Paving, HGV Parking Area, Truckcell 80, Road King, Cannock, UK
ABG
The New Hollies transport cafe has been serving drivers and travellers on Watling Street (A5) since 1933.
The cafe has grown significantly and hundreds of HGVs visit each week creating a demand for robust, sustainable parking.
Due to the high water table, permission was granted but with the restrictions to keep the water level at the pre development level. It became clear that permeable paving would meet the requirements.
ABG Truckcell was used as surfacing with Terrex as a filtration textile.
Truckcell is a heavy duty plastic paver able to withstand the forces exerted by multiple wheeled vehicles.
SuDS Permeable Paving, Park and Ride, Sudspave, Truro, UK
ABG
Following a successful park and ride facility in the west of the city and to reduce traffic further, an east park and ride facility comprising 1800 car parking spaces as part of a regeneration scheme.
The park and ride design focused on sustainability and protecting local habitats. Due to restrictions on run off levels Cornwall council opted for Porous Paving.
ABG Sudspave 40 permeable pavers were installed on free draining aggregate to enhance surface water drainage.
Sudspave was supplied pre assembles for rapid installation. The panels can be filled with topsoil, gravel or seeded.
SuDS Permeable Paving, Park and Ride, Truckcell, Truro, UK
ABG
Cornwall Council identified a requirement for a Porous Paving system for a park and ride being built in the east of the city. The system would need to meet all planning limitations relating to run off and cope with coach overrun as well as being able to resist the forces exerted by manoeuvring HGVs.
Truckcell is a highly effective source control system that manages storm water run off, as well as a cost effective SuDS compliant porous paving solution that facilitates rapid installation. Truckcell is manufactured using 100% recycled plastic and can withstand frequent HGV overrun
SuDS Permeable Paving, The Wave Surfing Lake, Washingpool Farm, UK
ABG
The Wave is a new inland-surfing lake, powered by 100% renewable electricity that provides the opportunity to surf all year round regardless of weather conditions or tides. The site’s entrance and car park suffered from boggy ground conditions following spells of wet weather and with approximately 2,750m2 of impermeable surfacing, there was limited potential for infiltration. The shuttle bus route between the main facilities and the car park is now surfaced with Truckcell 80 Permeable Paving blocks, filled with free draining angular gravel to allow rainwater to percolate down to the existing sub-soil.
SuDS Permeable Paving, Yorkshire Sculpture Park, Bretton, UK
ABG
Yorkshire Sculpture Park at Bretton Hall estate is the largest of its kind in Europe with growing visitor numbers year on year. As a result the site suffered from insufficient parking with the site’s overflow areas becoming unsuitable with uneven ground prone to rutting, localised flooding and loss of traction. To combat the sloping, poorly drained site ABG provided a highly efficient SuDS drainage system, employing a combination of their Geogrids, Geotextiles, and Deckdrain, all in conjunction with the free-draining surface of the Sudspave 40 permeable paving system to resolve the access and parking issues for the 150,000 vehicles that visit each year.
SuDS Pond - Groundwater Control, Pozidrain, Newcastle Airport, UK
ABG
From humble beginnings Newcastle Airport has grown vastly and expects 9.4m passengers annually by 2035.
Increasing the capacity of the existing storage lagoons is needed to continue meet current and future airport requirements.
Due to the high water table there is a risk ground water pressure would cause uplift of pond liners.
ABG Pozidrain was recommended to remove any uplift, manage groundwater and allow ground gases to escape. Due to being puncture resistant it also protected the liner.
The multiple functions of Pozidrain removed the need for imported stone reducing vehicles to site by 200 and increasing material savings.
Tree Root Protection, Woodland Access, Abweb TRP, Center Parcs, Woburn, UK
ABG
Part of the planning consent for Centerparcs included a roundabout and the creation of cycle bridleways. The aim to complete the work using a method sympathetic to the environment whilst avoiding damage to the tree roots. ABG Abweb TRP has a three dimensional cellular structure which when filled mitigates the vertical load pressure on the sub soils. The Abweb TRP cells act as a permanent form work to the road surface.In this no dig solution water and nutrients can flow into underlying soil allowing trees to flourish.
Vegetated Retaining Wall, Cutting Stabilisation, Webwall, Saundersfoot, UK
ABG
The local council was tasked with constructing a footpath within a restricted area allowing safer access to a busy health centre. It was important to maintain the natural green appearance. A retaining wall was required and had to be quick and easy to erect with minimal disruption.
ABG Webwall was chosen as the solution. The Webwall was quickly constructed using 4m x 1m panels which were filled with soil from the excavation and cutting. The wall was replanted to restore an naturally green appearance. Webwall was built in a quick cost effective way to create an environmentally friendly retaining wall
