Geomembrane PDM
About PDM
Geomembrane is a waterprof membrane that solves effectively problems with humidity and increases life comfort in the building. Its strong and flexible dimples resist against the mechanical impacts caused by the back filling of the ground avoiding any kind of damage on the surface of the waterproofing layer. The air gapcreated by the dimples of Geomembrane between the ground and building parts like basement walls or floors is ideal for all kinds of drainage.
The dimples of Geomembrane resist against compressions even higher than 180kNm² keeping continuously an air gap of 5,3l/m² between the walls or floors of the building and itself. This space is big enough for the drainage of the rain or ground water, as well as for the evaporation of humidity if supported with a suitable system of ventilation.
WHERE IS GEOMEMBRANE USED
Protection of basement walls and foundations
The underground parts of buildings must be protected against damp and ground water and this is necessary for a comfortable and also safety reasons. When rust affects the reinforcement of the concrete the structure system is also damaged and this can be dangerous for the stability of the building especially in critical situations like earthquakes. Therefore, foundations and basements have to be waterproofed. Moreover, the waterproofing materials are very sensitive. If not properly protected, they are under the risk of being damaged during the back-filling of the building site. Geomembrane's tough but flexible body absorbs mechanical impacts of ground parts like stones and gravel and prevents any such damage on the waterproofing layer even if they might hit the wall.
During the life-time of the building Geomembrane continues to protect the underground walls also against the attacks of roots and most chemicals which might be harmful for underground building parts.
Internal repair of floor damages caused by dump and humidity
Mould is a problem also for ground slabs. If no waterproofing is made during the construction period, damages and deformations appear on finishing layers of ground slabs caused by humidity.
Geomembrane is the ideal material for the internal damp-proofing of floors, because it can resist not only against humidity but also against vertical loads,as Geomembrane's 8mm high dimples do not squash down. So, a continuous air gap is provided between the existing and the new floor, which can be also ventilated at wall flashings.
Protection from ground slabs against humidity coming from the ground
Even if concrete slabs for open areas are coated with materials like asphalt, they have to be protected against the humidity coming from the ground. The dump-proofing layer must be also resistant against impacts, compression and tearing otherwise it can easily be damaged during the construction works for the application of the ground slab.
ENVIRONMENTAL RESPONSIBLY
Geomembrane is made of HDPE for whom we know that 85% of its contents can be recycled. Chemicaly is inert, so there is no product or compounds that can activate it and make any reactions.
BENEFITS OF THE GEOMEMBRANE
After it’s set, the Geomembrane provides:
Mechanical protection of the waterproofing material;
Humidity protection of the construction;
Drainage of atmospheric water in the basement walls;
Provides drying of the moisture from the outside of the construction;
Improves the sound insulation and the thermos insulation;
30 years guarantee of the material under normal conditions;
It can be put into the construction independently from the atmospheric conditions and after it is set, immediately starts in function.
MATERIAL FOR MONTAGE
APLICATION OF THE PRODUCT
Geomembrane is easy for installation independently from the atmospheric conditions. It is not a heavy material and its very suitable for transportation and transfer.
Its used as bedpan concrete, saves a significant assets, and it shortens the process of construction.
Internal repair of wall damages caused by dump and humidity
If basements are not correctly waterproofed from outside, the walls get mouldy and the damage of the humidity cannot be repaired by repainting or plastering from inside. If Geomembrane is applied together with a new layer of plaster or gypsum board,the final surface of the wall remains clean and smooth
