Background

This bridge abutment is one of the first Keystone wall system design in Brunei. The pre-cast concrete Keystone modular blocks can form a near vertical face and securely connected to Tensar’s Uniaxial geogrids. The geogrids reinforce the soil mass to create a strong and maintenance-free retaining wall, with a design life of up to 120 years.

Cranes or propping are not needed in its installation as the keystones are simply dry-laid and their geometry allows curves, corners, stairs and other features to be easily constructed.
