Water Management

Leca LWA has the ability to delay water runoff by a principle known as water detention. Proper detention provides a steady and manageable flow of water and reduces the risk of flooding.

Water Management

Leca LWA has the ability to delay water runoff by a principle known as water detention. Proper detention provides a steady and manageable flow of water and reduces the risk of flooding. Leca LWA has a highly porous internal structure and an abundance of voids between the grains. This property allows Leca LWA to detain a flow and thereby reduce the peak intensity of runoff from an area.

3. Sports Ground Filling
Leca® LWA provides a lightweight solution for effective drainage and with the engineering ability to be pneumatically blown into place through agile pipes up to 50m in distance.

5. Protect Piping Systems
Water drainage system can be difficult when the drain runs across a soft soil site. Leca® Lightweight Aggregate can be used as a light weight pipe surround to reduce the pressure to the underlying soils and minimize the likelihood of irregular settlement.
