TensarTech® TW1 Wall System

Provide, Services, Services

The TensarTech TW1 Wall System has been developed as an alternative to traditional retaining wall options, offering substantial savings in construction time and cost, combined with versatility

The system is comprised of a pre-cast concrete modular block facing, securely connected to Tensar uniaxial geogrids which reinforce the soil mass behind and create a strong and durable, minimal maintenance retaining wall. This possesses a design life of up to 120 years.

The TW1 concrete facing blocks, which form an 86o face angle, are simply dry-laid - typically with no cranes or propping required. The weight of the standard 150mm high block is suitable for manual handling. Their geometry allows corners, curves, stairs and other features to be incorporated easily, with a variety of colors available. A specialist TW1 Link System option with a vertical face and stainless-steel ties is also available, which allows for a masonry or brickwork facing skin to be tied to the structure, matching any specific site aesthetic needs.

The TensarTech Wall System has proven itself in thousands of projects, with many case studies available for review. You can also find the complete solution from just one source, with our team of experienced engineers. Using our sophisticated TensarSoil software, they can provide everything from free application suggestions to a full design and supply service complete with Professional Indemnity insurance cover.
