Concrete or old facings :

The surface of the base must be firm , smooth , without sharp protrusions, clean and dry, free of oils , paint, dust  etc .

Soil :

The earthwork should be tight and the available stones and sharp objects to be removed from the surface.

Before the membranes  application is placed a subject layer of geotextile .




Temperature of the foundation  :  minimum 0 C / maximum +35 ° C

Temperature of the air  :  minimum +5 ° C / maximum  +35 ° C




It is not allowable direct contact with the polymers of other groups, such as polystyrene, polyurethane, polyisocyanate, phenol containing foam.

The membrane is not resistant to bituminous materials , grease, tar , oils , solvents . If it is in contact with such surfaces , has to be used a separation layer of geotextile with a density of min.300g / m² , in order to be preventable the accelerated aging.


Installation Instructions

Technology of the installation :  In compliance with the existing Installation manual for roofing membrane Ruvimat

Method of attachment : Free laying  with a mechanical fixing or free laying with ballast

Technology of the welding : The overlaps  ( from 80 to 100 mm)  of the membrane must be welded by electric tools with hot air, hand held heat gun and roller or welding automatic tools with hot air, that have indiviul setting and control of welding temperature with a capacity of minimum +600°С.

The welds are carried out with a double welding  seam providing a chamber for testing the weld.

Recommended mode for the equipment :
Welding parameters  The parameters of the welding process include temperature, welding speed, air stream, pressure must  be chosen and checked according the weather conditions and the type of welding tools on the building area right before the welding process starts. The width of the joint must be at least 30 mm. Quality control of the welding joint is carried out by applying a pressure in the chamber between the welding joints .

Application limits
The application of PVC membrane  RUVIMAT BA 20  must be performed by people that have passed a training course .

The membrane is not UV stabilized and should not be applied to open areas under the influence of sunlight.
