Why does the fleece on the drainage disintegrate over time under the screed?
Moisture entering the structure through the covering and “travelling through” from the top down to the drainage carries water-soluble lime with it. This can attack the fleece part of the drainage, making the drainage ineffective. To prevent this, AquaDrain® FE+ is equipped with an intelligent special fleece which works as a supporting layer when the screed is applied. Once the screed has thoroughly hardened, the fleece will gradually dissolve.
