T-Wall & TerraLink® TechWall

TERRALINK and TECHWALL are complementary technologies to traditional Reinforced Earth. Where Reinforced Earth is particularly useful in situations of creating embankments, TERRALINK and TECHWALL are useful in CUTTINGS. 

T-WALL is a precast stack-able modular unit for rapid low level installations and also to 20 meters. Can be installed in wet environments and use selected back-fill options.

T-Wall is a gravity precast retaining wall system using modular units and relaxed back fill selection, enabling the most efficient use of materials and reduction in costs. T-Wall is an easy installation with no mechanical connections, stack-able with variable length stems and reducing back. T-Wall is ideal for Smart Motorways, hydraulic applications with synthetic re-bars and installation in the wet. With over 1 million sqm installed and wall heights up to 20m this is an assured solution.

Aesthetic panel finishes to suit any design and the thin wall sections also reduce the carbon emissions in the manufacture and transport of materials. T-Wall has a certified EPD, details found below and is understood to be the world’s first retaining structural EPD of it’s type using CEMIIIA concrete

The TerraLink technique allows the construction of Reinforced Earth walls in front of existing structures or slopes where there is a narrow space between them by effectively connecting the two structures together. It is an excellent solution where the site constraints prevent construction using other types of retaining wall.

There are two methods of connecting the Reinforced Earth wall to the existing structure or slope to form a shored retaining wall, either a direct connection, or a frictional link which incorporates soil reinforcement attached to the existing structure or slope which then overlap with the reinforcement from the new structure, the overlaps between the reinforcements ensure the frictional connection on both sides of the structure.

Reduced footprint at the base of the structure
Reduced excavation works
Reduced backfill
Speed of construction
Avoiding the need to demolish existing structures
Minimal disruption to traffic flow

TechWall is a precast counterfort retaining wall system engineered to site specific requirements, this enables the most efficient use of materials and reduction in costs. TechWall can be designed using state of the art numerical analysis to produce the thinnest panel sections thereby increasing the surface area which can be delivered, wall units can be supplied up to 18m high. Our innovative solutions can also been built under water (see brochure) . Over 700,000 sqm have been supplied with an average height of 7m.

Thin wall sections reduces the carbon emissions in the manufacture and transport of materials.
