Reducing Settlements and Soil Pressure with Improved Drainage Capacity
Low bulk density and high strength, combined with easy handling makes LECA® LWA a very competitive lightweight aggregate solving geotechnical problems as:
- Load compensation
- Reduced settlements
- Reduced earth pressure
- Frost insulation
And LECA® LWA can be reused 100% even after laying under the road for more than 100 years.
Wall and Slab solutions with focus on Thermal & Sound insulation, Wet rooms and Impact resistance
Lightweight, Thermal and Sound insulation are the key comfort factors to use LECA® LWA in your housing project. Whenever building a new villa or renovating a hospital, bothe the owner and user are seaking comfort in utilizing and maintaining the building.

Leca's 75-year history has grown thanks to the environmentally friendly and durable material, lightweight aggregate. Leca® LWA is made from domestic clay, which can be used almost limitlessly in construction. There is no concern about the availability of raw materials because there is enough clay obtained from nature. However, we are not ready as a company, and we are not stopping here.
Curbing climate change and adapting to it requires concrete change from the construction industry. The change is not easy, and not all the steps are clear yet, but the joint journey must start today. Everyone must do their part to ensure a sustainable future for all of us.
