Roof Waterproofing
ROOF WATERPROOFING:
Roof waterproofing is the process of protecting a building's roof from water damage by applying materials that prevent water from penetrating the roof surface.
Various waterproofing materials, such as asphalt coatings, liquid-applied membranes, and pre-formed sheet membranes, can be applied to existing or new structures, creating a barrier that prevents water from seeping into the building. Additionally, it will support the reduction of heat that is absorbed by the roof.
When choosing a roof waterproofing option, it is important to consider different factors such as the climate, type of roof, expected life span, and the intended use of the building.
Some of the common roofing system options:
Built-up roofing (BUR): This traditional roofing system consists of multiple layers of waterproofing material built up on the roof surface. The layers are sealed together to form a waterproof barrier.
Single-ply roofing: This is a type of roofing system commonly used for flat or low-slope roofs that consists of a single layer of waterproofing material, such as TPO or PVC. The material is typically heat-welded or glued to create a seamless, waterproof barrier.
Metal roofing: Metal roofing systems can be waterproofed by applying a coating or membrane to the surface. The coating or membrane provides a barrier against water penetration and protects the metal from corrosion and other forms of damage.
Spray foam roofing: This roofing system consists of a layer of spray foam insulation applied to the roof surface. The foam is then coated with a waterproofing material to create a seamless and waterproof barrier.

Mapei provides a wide range of technologies and systems that can provide adequate waterproofing systems based on the roof design, waterproofing requirement, application, and durability aspects.
Mapei’s waterproofing is divided into the below based on the application criteria:
?? liquid-applied membranes:
-? ? ? ? ? Acrylic Based Applied Waterproofing: AQUAFLEX ROOF is a ready-to-use colored waterproofing product for sloped or vertical surfaces which forms a continuous, flexible, waterproofing membrane resistant to all atmospheric conditions and UV rays and guarantees long-lasting protection for the substrate.
-? ? ? ? ? Polyurethane Membrane: PURTOP EASY is a highly elastic and durable membrane that offers significant advantages, particularly when seamless systems and geometrically complicated connections with different types of substrates are required.
-? ? ? ? ? Polyurea Waterproofing: PURTOP is a waterproofing material that is often used in industrial and commercial settings which quickly cures to form a durable, waterproof barrier. Polyurea is known for its excellent resistance to water, chemicals, abrasion, and impact, making it an ideal option for waterproofing surfaces exposed to harsh conditions.

?? pre-formed singly-ply membranes:
-? ? ? ? ? PVC/ TPO: MAPEPLAN/MAPEPLAN T is a range of PVC (polyvinyl chloride) / TPO (thermoplastic olefin) which are commonly used for flat or low-slope roofs.
MAPEPLAN T “TPO roofing” is known for its durability, energy efficiency, and weather and UV radiation resistance. The membrane is welded together using hot air, creating a continuous and seamless barrier against water penetration.
The physical resistance of TPO, such as tears, punctures, and impact, make it a perfect selection for exposed flat roofs with high durability requirements.

Finally, it is highly important to have the waterproofing systems installed by a professional roofing contractor to ensure the proper and correct application to the highest standard. Improper installation of waterproofing materials can lead to leaks, structural damage, and other problems that can be expensive to fix.
