T-Block Reinforced Soil Wall System: Geogrid Tenax TT, T Block & Ekotex®
As part of the Section 278 works for the Meadowside housing development, a retaining wall was specified beneath the existing main road and access road into the scheme. This retaining structure needed to also accommodate a vehicle containment barrier.
The initial design brief was to provide an aesthetically pleasing and cost effective alternative to a traditional reinforced concrete wall, whilst satisfying the requirements of the adopting authority. The Geosynthetics Engineering Department prepared a technical recommendation and from this were able to demonstrate that a reinforced soil wall would meet the requirements and offer significant cost reductions over a concrete wall. The geometry of the site dictated that a vertical retaining wall to a maximum height of 5.4m would be required with
The T Block wall system was proposed to provide a maintenance free aesthetically pleasing finish to the structure. The T Block wall system utilises the unique T Clip connector which provides a mechanical connection between the Tenax TT geogrid and the precast T Block. The strength of this connection and the mechanical properties of the Geogrid Tenax TT are a key factor in allowing the design a value engineering solution for the project.
“Geosynthetics were able to assist in providing a cost effective solution to our retaining wall requirements on this scheme. The T Block system was a well engineered system which assisted in ensuring the scheme was designed and delivered on time and within our budget constraints.”
