The project consists of the design of an installation of demarcation barriers on the DLR network, running from Bow Church to Stratford, and Limehouse to Tower Gateway. The barriers will provide a visual and physical boundary where DLR and Network Rail lines run adjacent. TECHNO-CRETE^® was chosen as the foundation material for the embedded posts. An innovative, eco-friendly postmix, TECHNO-CRETE^® is a hydrophobic polyurethane foam foundation system.

Made from a blend of reprocessed oil from the catering industry and sustainably grown rapeseed oil, it is rapidly becoming the prime choice of foundation material, offering a green and cost-effective alternative to concrete post-mix. Supplied as two 0.9kg bags which are mixed together with no water required, the mixture foams to form a structurally robust, solid foam to securely hold the posts in place.

With a significantly lower ratio of material required when using TECHNOCRETE^® on a job compared to cement-based products, there is also a much lower amount of CO₂ emissions released into the atmosphere. The larger the job, the more that Environmental saving increases. The project used sustainable GRP and foundation materials throughout the route, while the client’s welfare and office facilities were fed from power generated by solar panels, effectively running the job as carbon neutral

We contacted Complete Composite Systems during the design phase to assist us to deliver the project as carbon neutral. Through various value engineering workshops, we challenged traditional design methods and were not only able to achieve our goals, but also significantly reduce manual handling and the amount of excavation required should we have used traditional concrete, and the additional temporary works requirements associated with curing times.
