Does Leca® Lightweight Aggregate Float Away?

Leca® LWA is used extensively as a lightweight aggregate for civil engineering and structural applications, such as Rail, Highways and Bridges. Through promotion and specification, our client base is continually finding further solutions and interesting uses for this special lightweight aggregate. Using free draining Leca® LWA as a structural material within the road build up will intercept the percolating water and water rising by capillary action from the sub-formations and direct the rising water away from the upper construction layers to improve the load bearing capacity. Carriageways in cuts that extend below the natural level of the groundwater, frost damage and loss of load bearing capacity can also be reduced by forming drain trenches filled with Leca® LWA at both sides of the road, along which the water is led away. Used within the carriageway drainage, Leca® LWA will help filter and increase microbiological breakdown of pollutant run off from fields and highways.
