Expanded clay is a high quality, durable lightweight aggregate, that has been used for over half a century. The main characteristic of expanded clay is low density combined with high strength.
Expanded clay is durable has long lifetime and requires no maintenance.
Expanded clay can reduce the weight of concrete by almost 50% without compromising strength.
It is 4-5 times lighter than loose gravel or loose fill crushed stone.
It can be used as loose fill and insulation in road and rail embankments and can sustain dynamic loads from heavy high-speed trains.
Expanded clay is 100% recyclable or reusable. There are no problems with disposing of demolition waste and no use of new materials, new resources or new energy.
RESISTANT TO FIRE
It is classified as a fully non-combustible material. It has no reaction to fire, does not emit gases or smoke and retains its mechanical resistence and all other thermal and physical characteristics. It is an excellent protection against fire.
A THERMAL INSULATING MATERIAL
Insulating performance of loose fill expanded clay is in the same range as the best values of wood. Concrete made with expanded clay can be up to 12 times more insulating than normal concrete: winter and summer comfort is guaranteed.
REDUCES THE NOISE
It works well for both acoustic insulation and sound absorption. It is suitable in the home as a wall between dwellings and good outside as a barrier between houses and noisy infrastructures.
HAS A NEVER-ENDING LIFE
Expanded clay is chemically inert, contains no harmful substances or gases and is completely neutral. Its resistance to chemical attack is comparable to that of a glazed tile, glass or other ceramic materials.
