Indicators / Standards
RUVIMAT BA 20 type Т is produced in compliance with БДС EN 13967: 2012 for moisture insulation of buildings , including underground parts of buildings.
Class F acc. European classification for reaction to fire EN 13501-1.
Rolled sheet membrane , homogeneous
Surface: smooth , matt
Color – black – for waterproofing of basements
– signal – for waterproofing of tunnels
Membrane with a signal color is produced on request at a minimum order quantity of 4000 m²
Each roll is packed in clear LDPE film
Roll length: 15 m
Roll width: 2 m
Roll weight: 85,00 кg
Rolls on the pallet: 21 rolls
Rolls must be stored in horizontal direction on the pallets in the original packing without direct exposure to sunlight, rain and snow. Storage following these rules guarantees no expiry date.
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 .
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.
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 .
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.
