Roof Membrane Waterproofing
Inseal’s spray applied polyurea cures in minutes forming a seamless, flexible and monolithic roof membrane that is water tight and durable. The dense roof coating exhibits excellent tensile and tear strength which accommodates cyclical movement. Inseal Polyurea can be applied to a wide range of roof structures and materials such as colour steel long run, asbestos sheet also known as ‘super 6’, concrete and ply flat roofs having torch on or butynol membranes and refrigerated buildings installed with sandwich insulated panel (SIP) roofing
Leaking roofs, particularly that of commercial and industrial buildings and processing facilities present the asset owner with a dilemma. Businesses can not afford to cease operations whilst major roof replacements are carried, the loss of operational income is far too high. The same is true for commercially tenanted properties, where by the occupier cannot operate in the scheme of major building renovations. Typically, the owner will undertake spot repairs as a short-term solution to keeping valuable machinery, goods and office space dry from water leaking in from the roof. The reality is that these repairs are short lived and often require repeating every couple of years, adding to the maintenance costs of the building.
Where an asbestos roof is concerned the asset owner has an even greater challenge. Full replacement requires suitably licensed contractors to remove and dispose of the hazardous waste at huge cost. During the removal process the asbestos sheet is disturbed thus requiring internal isolation measures and air monitoring to ensure occupants with the building are not at risk of breathing air borne fibers. Adding on the cost of temporary weather protection, such as scaffolding and shrink wrap to keep the building space dry during roof sheeting replacement, can inflate refurbishment costs in to the millions. Inseal can provide with a cost effective solution by applying our special polyurea, providing a seamless monolithic roof membrane that waterproofs and protects whilst adding structural integrity
Polyurea's dense molecular profile results in a coating that is completely water tight. The applied membrane is completely seamless thereby mitigating any weak failure points. The impermeable membrane is not only suited for waterproofing applications, it is also effective in permanent immersion scenarios
Polyurea has a very broad glass transition. At temperatures of -40°C to 120°C polyurea it retains it's flexibility, elongation and resists cracking.
Polyurea's ability to adhere and mold itself to various substrates means that our system can be directly applied to the existing roof structure. This means that normal business operations can continue with little to no interruption
Polyurea is incredibly flexible, with elongation of over 400% and remaining permanently elastic, it has the ability to bridge cracks and accommodate high movement joints subject to cyclical movement without splitting
It is not uncommon for waterproof membranes or protective coatings to be exposed to puncturing forces during the serviceable life. Inseal's polyurea and polyaspartic will not crack or flake when subject to heavy impacts
What is polyurea
Inseal’s polyurea is a specially formulated pure polyurea designed specifically for use in waterproofing and protective coating applications. The two component product is processed though specialist equipment where it is heated and pressurised. The material is mixed and dispensed through a spray gun where a rapid cross-linking reaction forms a polyurea coating that can be built to any thickness in one pass. To discover more about polyurea, see ‘Polyurea 101’ here.
