Waterproofing with bituminous membranes
The classic method of waterproofing with bituminous membranes is the oldest of all, continuously developed by thousands of manufacturers around the world, and the most affordable. Bituminous membranes are materials gathered in rolls of 10-15 m2, with basic components: the middle armature made of fiberglass or polyester and the bitumen itself, which can be oxidized or modified with polymers to improve the characteristics for specific applications.
It is installed on the concrete surface using open flame, with the help of a gas burner, which heats the membrane until it melts and vulcanizes on the surface of the concrete, which is treated with a bituminous primer, which increases its adhesion capacity.
Waterproofing with synthetic PVC or TPO membranes
Commercial roofing Denver CO contractors affirm that synthetic membrane waterproofing is an ultra-fast system developed especially for commercial modular buildings with imposing surfaces and few elements protruding from the roof surface.
These membranes are manufactured in rolls of 1-3m width, of white or light gray color, composed of a synthetic PVC or TPO material, partially or totally reinforced with fiberglass or polypropylene fibers. They are mechanically installed, using special accessories, even directly on mineral wool or extruded polystyrene, and the joints are welded with a strong hot air blower.
Waterproofing with liquid membranes
This waterproofing solution is characterized by the application to the surface of the roof of a liquid paste with polyurethane content, using brushes or rollers. It seals the roof completely and, if chosen in light colors, can improve its energy-efficiency, modifying its reflective properties.
