St. Astier clay blocks construction mortars.

Clay blocks construction is extremely versatile and efficient. Its energy saving characteristics combined with the build quality and speed are such that building with clay blocks has become a prominent method in most European countries.

From very large projects to house extensions, the easiness of build and the thermal and acoustic results have proven to have significant advantages over other construction methods.
