The drainage membrane effectively solves the problems with moisture and mold and increases the comfort in buildings.
Leave your details and our employees will get in touch with you to proceed your order.
The robust and flexible sockets on the drainage membrane resist the mechanical influences caused on the outside of the building and the ground, avoiding damage of the surface of the waterproofing layer. The air holes created by the sockets on the drainage membrane are ideal for any type of insulation. The sockets of the drainage membrane are resistant to compression even higher than 180 kN / m², continuously maintaining an air space of 5.3 l / m² between the walls or the floor of the building and the sockets. This space is large enough to drain rainwater or groundwater, as well as to evaporate moisture if there is a suitable ventilation system.
The composition of the drainage membrane, which is very flexible, absorbs the mechanical effects emanating from the underground parts and prevents damage to the waterproofing layer.
Interior repair of walls damaged by moisture and mold
Placing the drainage membrane together with a new layer of plaster or drywall prevents the appearance of mold and the surface of the wall will remain clean and smooth.
Internal repair of damage of the floor caused by moisture and mold
The drainage membrane is the ideal material for internal prevention of moisture and mold on the floors in any residential area.
Protect the ground plates from moisture coming from the ground
Even if the concrete slabs for open areas are covered with a material such as asphalt, they must be protected against moisture coming from the ground.
ENVIRONMENTAL RESPONSIBILITY
The drainage membrane is made of HDPE, 85% of which can be recycled.

More detailed information about the installation
The surface must be sound and clean. Local inequalities to be corrected. Remove cracks and protruding fittings and fill the openings with a suitable solution.
Unroll the drainage membrane, cut to the required length and mechanically attached to the surface. The membrane is always laid with the stamped sockets against the wall.
For vertical surfaces up to 2 m deep, the drainage membrane is laid horizontally. The overlap between two membranes is 20 cm or 7 sockets..
For depth of more than 2 m the drainage membrane is laid vertically, and no joint should be obtained, open from above. The overlap is 20cm or 7 sockets.
Fastening is done at the upper end of the membrane with nails, through mounting washers every 30 cm. Adjust the impact force when using a nail machine.
To prevent soil or sand from entering between the drainage membrane and the wall, a covering strip is applied to the upper end of the membrane.
In the presence of a high level of groundwater, it is necessary to lay a roll of waterproofing, which ends 30 cm above the highest level of groundwater.
In order for the drainage membrane system to be effective, it is necessary to build a local drainage, and in some cases a pump may be installed to remove the collected groundwater.
For better mechanical protection or degree of drainage, the membrane is placed with geotextile to the soil layer.
It is placed on floors without mechanical fastening. It is recommended to use double sided mounting tape for better watertightness.
Sealing strips are placed around chimneys, vents and supports as shown in the diagram.
For external walls, bituminous sealing tapes can be used for better watertightness of the joints at the fugues, and the covering tape is sealed with special adhesive.
When laying the drainage membrane on the inside, use wooden slats, on which the cladding and finishing coating is applied.
If the final coating is plaster, an additional netting can be used. The fastening is done through the mounting washers in a scheme of an equilateral triangle with side 30cm.
