Civil Engineering Materials

Achilles provides various solutions (construction methods and materials) that contribute to disaster prevention and mitigation such as repairs of roads, tunnels, bridges, and seawalls as well as measures for aging of structures.

Civil Engineering Methods

As civil engineering methods for tunnel repair and road widening construction, Achilles offers the tunnel back-fill grouting method and the lightweight fill method that employ our Airlon-R (non-fluorocarbon on-site rigid foaming urethane foam) as well as a lightweight fill method that employs styrene foam blocks.

Major Products (Methods)

Tunnel Back-Fill Grouting Method (Tn-p Method)

Tn-P Method (Work Scene)

The Tn-p Method is a tunnel back-fill grouting method that injects Achilles Airlon-R (non-fluorocarbon on-site rigid foaming urethane foam) into the cavities behind the concrete lining of tunnels in order to prevent damage in the event of disasters such as earthquakes.

Lightweight Fill Method (Urethane LH Method)

Urethane LH Method (Illustration)

The Urethane LH Method is a lightweight fill method that employs Achilles Airlon-R (non-fluorocarbon on-site rigid foaming urethane foam) as a fill material for foaming on-site.

Lightweight Fill Method (EPS Method: Styrene Foam Civil Engineering Method)

EPS Method: Styrene Foam Civil Engineering (Illustration)

The "EPS Method: Styrene Foam Civil Engineering Method" is a civil engineering method (lightweight fill method) that stacks large styrene foam blocks as a fill material to effectively make use of the material's characteristics.
