Coastal protection concrete matress ENKA®-MATTRESS

Enka-Matress is a two layer geotextile mattress filled with fine aggregate concrete after installation. The mattress acts as a shutter till the concrete is cured. The specific hydraulic characteristics of the fabric allow a slow evacuation of the concrete mixture water and limit the fine cement particles from getting through the fabric. Both result in a concrete which gives high strength, density and abrasion resistance whether constructed above or below the water. The two layers are connected in order to control the thickness of the mattress. We produce 2 types of Enka-Matress: Permeable concrete mattress with filter points Impermeable concrete mattress with connection threads Enka-Matress with filter points The mattress is woven together at regular intervals to form the so called filter points. These filter points act as filters along which water can drain off and release water pressure behind or under the mattress. The fine pore size of the filter points prevents the transport of fine soil particles. Enka-Mattress with connection threads The mattress has internal connection threads. The specific length of the connections threads controls and provides a constant thickness after filling up with concrete. Due to the structure of the mattress, once hardened it forms an impermeable protection layer.
