Roof failure is a primary cause of damp, water leakage and water intrusion into a building.
Traditional methods of removing and replacing roofing material can be expensive and expose the structure to additional damage.
Spray Polyurethane Foam Waterproofing roof sealing
SPF can be used as a re-roofing material , applied directly on the existing roof structure.
It provides two important benefits to a building through waterproofing and increased insulation value.
Further, the application of SPF to an existing roof structure is simple and fast.
The expanding foam is simply applied directly over the existing metal, wood, concrete, membrane or built-up roofing material.
Once the SPF has been applied to the proper thickness, a protective layer of elastomeric coating or gravel is applied over the insulation.
This combination of foam insulation and protective layer produces a durable, weather-resistant surface that is strong enough to walk on.
Ideal waterproofing method for flat roofs on commercial and industrial buildings
In new construction, SPF is ideal for flat commercial roofs because it is lightweight, durable, and requires less maintenance compared to traditional roofing systems.
Once applied, SPF can help make roofs weatherproof and has a 30 year expected service life.
Additionally, as a roofing material, SPF also increases the structural strength of the building by providing wind uplift resistance, which can be critical in high wind areas.
Waterproofing with insulation benefits
When installed on the interior of walls or as a part of the overall design strategy to improve comfort, indoor air quality and durability, and to reduce heating or cooling costs.
Both walls and floors can be places of air infiltration, especially in industrial settings, and have the potential of water intrusion, especially in the form of water vapour.
SPF in these areas can help promote a healthier and more environmentally friendly space for the occupants.
