Concrete filling Mattress
Mattresses made of double-layer fabrics (polyester and polyamide) with high strength . Particularly suitable as mattresses for erosion control and / or stabilization of banks and slopes, protection and ballast of underwater pipelines , flexible formwork for any underwater injection with cement mixtures.
The filled structure has a thickness ranging from 12 cm to 33 cm. The quality of concrete used is extremely important. The principle applied to remove the excess water is based on the evacuation of the same through the pores of the fabric (due to the pressure exercised by the mixture pumping ). Then the fabric will work as a sieve and it is designed to prevent loss of fine particles through the pores.
