The DURABASE DR 80 drainage mat is particularly suitable for creating large surface drains in combination with tile coverings, as required on balconies and terraces. DURABASE DR 80 forms an effective drainage and additional sealing between the building waterproofing and the surface structure above. Moisture that seeps in through the surface structure is effectively drained away by the drainage surface formed by the studs. Ideal for laying under screed or gravel and chippings bedding, the fleece on the top prevents the drainage channels from clogging.
