A roof, a balcony or a terrace is constantly exposed to humidity, ultraviolet degradation, weathering, acid rain attack, mechanical wear and ongoing movement stresses. Leaks happen as a result. The professional, long lasting waterproofing solution is offered by the MARISEAL SYSTEM.
The MARISEAL SYSTEM is a group of coatings based on Polyurethane resins, which in combination, creates a seamless membrane on a roof, a balcony or a terrace, that protects the building structure reliably and on a long-term basis, even under the most difficult conditions. 
Professional waterproofing applicators in over 35 countries in Western Europe, Eastern Europe, Middle East, Africa, Asia and Australia, use the MARISEAL SYSTEM for demanding waterproofing. The reasons are:
ADVANTAGES:
Simple application
When applied, forms a seamless membrane,without joints or leak possibilities.
Strong resistance to water
Crack-bridging up to 2mm, even at -10oC.
UV-stability
Maintenance of its mechanical properties over a temperature span of -30oC to +80oC.
Provides water vapor permeability (breathing)
Provides full surface adhesion
The waterproofed surface can be used for light, medium or heavy pedestrian traffic, depending on the choice of the appropriate MARISEAL SYSTEM top-coat.
Resistance to detergents, oils and diluted acids and bases.
Easy and fast local repair, if the membrane is mechanically damaged.
Low cost
Beside the main application field of Roof waterproofing, the application possibilities of the MARISEAL SYSTEM are almost unlimited:
USES:
Roofs
Balconies
Terraces
Wet rooms (Bathrooms, Kitchens)
Flowerbeds and Planter Boxes
Roof Car Parking Areas
Foundations
protection of PUR-spray foam
Concrete protection and many more
CERTIFICATIONS:
The backbone of the MARISEAL SYSTEM is the MARISEAL 250 which functions as the elastic and waterproofing membrane of the System.
The MARISEAL 250 is a one component, cold applied and cold curing, highly permanent elastic, Polyurethane coating that cures to a seamless waterproofing membrane.
The MARISEAL 250 has been tested by the by the German state testing institute for construction materials MPA-Braunschweig according the European Union Directive for liquid-applied roof waterproofing and was found conforming.
The MARISEAL 250 was certified by the German state Institute for constuction techniques DIBt-Berlin, with the European Technical Approval (ETA) and with the CE-mark and certification.
The MARISEAL 250 was also tested and approved by various state and private laboratories and institutes in different countries around the world.
