DURAL drainage membrane DR100++

Our DR100++ drainage mat is specially designed for outdoor use. It is perfect for laying on balconies and terraces. You can use it in conjunction with various covering constructions, such as drainage screed, gravel and chippings beds, paving pedestals or even direct laying.

With the versatile DR100++ drainage mat, you can achieve effective water drainage and protect your surfaces at the same time.

Laying Dural DR100++ drainmat:

Before laying the mat, it must be ensured that the substrate is properly sealed. A slope of approx. 2% is also required. We offer, for example, the waterproofing and decoupling membrane as a sealant.

1. Cutting DR100++ to size:
   The first step is to cut the mat to size. Mat joints can be laid with 3 rows of studs overlapping, which must be taken into account when cutting to size.
2. Laying the mat:
   The DR100++ drainage mat is simply laid loosely on the previously sealed surface with the mesh facing upwards. Adjacent mats are overlapped with a width of 3 rows of studs. To do this, pull the fleece up a little on the long side. Alternatively, the mats can be laid end to end. Then tape over the joints with the sealing strip WP and mortar.
3. Sealing wall connections:
   If necessary, the wall connections can also be sealed with the tape and flexible mortar.

After laying, the rest of the covering construction can be started. Laying under gravel/split bed, drainage screed or pedestals is possible here. The DR100++ drainage mat can also be used for direct laying of at least 2 cm slabs.
