Need a retaining wall or slope design for your project?
Tensar’s design team can produce a free-of-charge “Application Suggestion” to illustrate what Tensar can achieve and how much value can be added to your project.
The TensarTech TW1 Wall System delivers substantial savings, as well as long-term durability and architectural versatility, compared to other types of retaining wall systems.
This system is comprised of a pre-cast concrete modular block facing, securely connected to Tensar uniaxial geogrids, which reinforce the soil behind it to create a stable structure with up to 120 years of design life.
The TW1 concrete facing blocks, which form an 86° face angle, are simply dry-laid. No propping of the face or cranes is required for the construction. The weight of the standard 150mm high block is suitable for manual handling. Their block geometry allows corners, curves, stairs and other features to be incorporated easily, with a variety of colours available.
The TensarTech TW1 System includes advice, training and services from Tensar’s design and on-site teams, as well as three specific products. These are Tensar uniaxial geogrids (high-density polyethylene with extremely high durability and no corrosion potential), TW1 modular blocks (high strength, durable factory-produced pre-cast concrete blocks) and Tensar TW1 connectors – for high-strength connection between blocks and geogrid reinforcement.
