Over 1800m2 of Stonebound resin bound permeable paving has been installed at Kings College University London to upgrade the existing surfacing for the historic quadrangle. The Strand Quad has been a part of King’s since the original university building (the King’s Building) was completed in 1831.SURFACING REQUIREMENTThis project aimed to modernise and improve the surface of the Quad and provide engineering research laboratories and teaching space for new undergraduate engineering programmes in Strand Campus Quad basement levels -1 and -2.A significant part of the plan was to remove the tired, worn asphalt and replace it with a new Resin Bound gravel surface, releveling and refurbishing the King’s Building steps.The requirement was to provide a clean, modern looking finish whilst remaining sympathetic to the Quad’s history and its surrounding, including the King’s Building and the East Wing of Somerset House, which are both Grade I listed. The paving needed to be decorative, low maintenance and durable with good slip resistance for the historic courtyard.Addagrip approved contractor TP Surfacing and Coatings were first contacted about the project by Farrans back in March 2009 to assist with the design, specification and installation of over 1800m2 of surfacing at the university. Stonebound permeable resin bound paving was selected to create the two colour design in bespoke blends and work commenced in April 2022 on the transformation.The surfacing was completed in May 2022 to the client’s satisfaction.Find out more about resin bound paving systems for courtyard projects

'NO-DIG' RESIN BOUND SURFACING SOLUTION FOR PARK IN PUTNEY, LONDONTerrabase Rustic was selected for a ‘no-dig’ project creating new pathways across existing grassed, macadam and gravel areas in a popular park in Putney, London.Addagrip approved contractor True Grip Ltd was approached by the local authority to provide a quote and proposal to upgrade the existing pathways and create new paths to the Leader’s Gardens, a small public park lying alongside Putney Embankment, opened in 1903.SURFACING REQUIREMENTOne of the issues to be resolved was that the tree roots could not be disturbed so a ‘no-dig’ system had to be applied around the trees and rooted areas. For these ‘no-dig’ areas True Grip specified Addagrip’s innovative Terrabase Rustic system to be laid directly onto the existing grass and directly over the rooted areas, creating a new pathway. This meant that the trees and tree roots were not disturbed and due to the porosity of the Terrabase Rustic system, precipitation would not be reduced, irrigating the existing surface without changing the trees’ climate or environment.Over 250m2 of Terrabase Rustic Oak 6 -10mm aggregate blend was selected to provide attractive, hard wearing, natural aggregate pathways that are low maintenance, seamless and in keeping with the park setting. The porosity of the Terrabase Rustic system allows essential drainage to reach the tree roots and provide all year round access for pedestrians and wheelchair users.The project was a great success and the paths now provide a circular route around the Beverley Brook area.

Bradfield College, located in the heart of Berkshire, is a school for 13-18 year olds, providing an 'education for life'.Set up in 1892, the school has its own church as part of the grounds, which has remained closed for a number of years.However, work has been completed recently to connect the church to the school, and convert it into a learning hub for academic purposes - providing students with the space to work individually or collectively to further their learning, preparing them for life in the 21st century.ChallengeNationwide metal & single ply roofing contractors Salmon Solutions provided the solution when it came to the cladding - using elZinc® standing seam cladding in Rainbow Gold to elevate the cladding, giving a sophisticated modern feel to the metal and glass exterior.SolutionTo get a secure fix, Salmon Solutions turned to use Fixfast SPIDI® Max brackets and rails as part of the vertical cladding solution. SPIDI Max brackets are versatile to be used in a wide range of applications, as well as being suitable for horizontal or vertical applications - one bracket for both fixed and sliding points, and available in 3 material grades: aluminium, A2/304 stainless steel, or A4/316 stainless steel."We have a great working relationship with Fixfast and use their products on the majority of our projects. Fixfast - as always - were reliable and efficient with both service and the technical info, which allowed us to incorporate not just their fixings but the SPIDI helping hand system into this project."Charlie Whitman - Salmon Solutions Ltd

As part of the £25 million Wolverhampton Academy Trust sponsored Bilston Academy, BCL are proud to have been part of the overall process. This project was delivered through the BSF programme by Carillion PLC and was designed by Capita. The academy was designed with the ability to deliver a modern multi-disciplinary education centre for the 1200 students of Wolverhampton Academy in mind. The building is made up of 4 differently themed zones, a dedicated engineering hub, a science super-lab and a combination of grass and astro-turf sports pitches.Using 69 x 44 mm of Siberian Larch, the external walls were covered, with the timber installed vertically at 100 mm to form an open screen detail across the building, including the plant room and roof areas. Each slat was treated to Class 0 SSF, using the non-com impregnation system from Lonza Wood Protection. In doing this, BCL ensured the building would have complete fire protection for its entire life without requiring any maintenance.As per all BCL panel systems everything was designed and pre-fabricated off site into a panellised system, fitted using secret fixings. Installation time was dramatically reduced along with on-site waste, meaning the 3000 m2 envelope was constructed quickly and efficiently.Client: Wolverhampton AcademyArchitect: CapitaContractor: Carillion PLCLocation: WolverhamptonCompletion: April 2013 Siberian LarchFSC CertifiedSecret FixingsClass 0 SSF

Delta’s Structural Waterproofing Consultant, Paul Green, CSSW alongside Delta’s MD, Kevin Dodds, were appointed to the design team to collaborate with the Architects, Engineers, Main and Sub-Contractors to fulfil the role of Waterproofing Design Specialists in providing a reliable, watertight solution for this substantial project.The large-scale basement project consists of a 4-storey deepbasement located close to the River Thames in Central London.The proposed subterranean space would offer multiple usage. This complex project required a waterproofing design which is, able to cope with intermittent/regular hydrostatic pressures created not just by groundwater, but also geographical tidal impacts from the river Thames and potential stress challenges caused by the surrounding infrastructure such as heavily trafficked railway lines in the development’s vicinity.Structures that experience a high level of vibration fromsurrounding infrastructure can, over time, have a high propensity to suffer cracks, which could lead to failure of some waterproofing solutions, so therefore careful considerations should be incorporated into the overall waterproofing design from those aspects and, the impacts these factors can have on an elected waterproofing system.Delta’s design philosophy rotated around creating a robust and suitable waterproofing design, the structure design, a continuous system, sequencing and installation, future maintenance, and serviceability, whilst able to fulfil requirements set out in BS 8102:2022 Protection of below ground structures against water ingress. Code of practice. The British Standard which governs waterproofing of substructures.
