Cold Applied Liquid Roofing

RoofCare Impermax is a flame-free, single component, quick-curing liquid polyurethane waterproofing solution.  Cold-applied to form an elastomeric, seamless membrane, Impermax will waterproof virtually any substrate. The liquid Polyurethane Rubber is hand applied and reinforced.

Systems have been developed to solve the problems associated with the long-term waterproofing of flat roofs, gutters and pitched roofs.

RoofCare provides flexible, durable, long-lasting protection for up to 25 years. Systems offer a cold liquid applied, breathable, seamless finish that moves with the roof and allows vapour release from the existing substrate.

Asbestos Cement Roofing & Cladding

Asbestos sheeting was originally introduced as a lightweight alternative to commercial slate and tile roofing. Fibres of mainly white chrysotile asbestos provided the strength and flexibility to allow cement sheets to be pressed into standard profiles that carried a realistic 50 year life expectancy.

Manufacture continued until the early 1980′s when the dangers of asbestos led to its replacement, mainly with PVA cellulose.

Old leaking asbestos roofs present a special maintenance problem. Sheets are fragile and often cracked while loose, corroded fixings add to lift and leakage.

The dangers of disturbing the asbestos sheet means even the simplest repair must be undertaken by specialist contractors to avoid airborne release of harmful fibres. Stringent disposal regulations means replacement is costly and hugely disruptive.

Over-sheeting adds weight, risks disturbing the sheet through fixing and may lead to condensation without addressing the underlying problem of deteriorating asbestos cement. This scenario is faced by thousands of industrial and commercial units throughout the country.

RoofCare Asbestos Encapsulation

A safer and more cost effective solution to the problem is total sheet surface encapsulation.

RoofCare Impermax is the ideal system. The specification calls for the use of Impermax to seal bolts and minor cracks as standard before encapsulating the sheet with a fully breathing silicone membrane to provide an enduring flexible, waterproof solution.

Asbestos cement sheets are vapour permeable, often with a high moisture content. Unlike most coatings, RoofCare Impermax provides a fully breathing membrane that will not crack or blister.

Benefits:

Encapsulation with RoofCare Impermax means the sheets remain undisturbed, eliminating the considerable cost, disruption and stringent controls needed for the safe removal and disposal of the asbestos sheet.

Deteriorating cement, corroded fixings and long term sheet damage all contribute to a fragile leaking roof. RoofCare Impermax repels surface water creating a fully breathing membrane that allows the cement sheet to ‘sweat’ whilst keeping rainwater out.
