Advantages using LECA® LWA in infrastructure projects
Low bulk density and high strength, combined with easy handling at the building site makes LECA® LWA a very competetive aggregate solving geotechnical problems as:
Reduced earth pressure
The aggregate is natural and completely inert, containing no harmful substances or gasses, why leaching to the soil or ground water is not an issue. Actually LECA® LWA is used adtionally as soil enhancer to improve the structure of soils and help aerating them. Also, the aggregate is resistant to chemical or any animal attacks.
