Retention pavement

System for the construction of retention reservoirs, melioration drainage canals and culverts.

TRI-LOCK blocks are suitable for extremely dry soil that require gradual and natural irrigation.

The TRI-LOCK system is a large-scale load pavement that is dry-assembled. The area of the pavement consists of two elements that are repetitive – a lock and a key. The surface of TRI-LOCK allows fast absorption of rainwater and prevent fast evaporation. It naturally and gradually irrigates soil. It can be grassed. The system can be used for parking areas, reinforcement of river banks and flood protection levees.
