Roofing spaces are increasingly being used to house plant and machinery that service the building, or provide a ‘roof terrace’ that can be used by tenants. Both scenarios would require safe general access and may lend themselves to an inverted or ballasted design. A ballasted roof is one where the roofing membrane is overlayed with paving slabs or gravel. As the waterproofing system below is protected from all contact, UV degradation and temperature extremes, the system can be expected to have a life in excess of that expected of a normal liquid waterproofing membrane.
When used in combination with the appropriate insulation and finishing materials, an inverted waterproofing system can be easily created and installed to withstand heavy traffic. These inverted roofs are designed to allow compliance with the building regulations (Part L) and increase the thermal efficiency of the building, also reducing carbon emissions.
Optional for certain substrates
Elastaseal™ embedment coat is the base waterproofing layer reinforced with Elastamat™ glass fibre mat
Use as necessary to complete the system. Used on termination details exposed to UV above the insulation level
The system is then overlaid with an appropriate insulation board system, filtration layer and then the required finishing material, e.g. stone or block paving (support pads may be needed). ballast may be used around the perimeter details or near plant and equipment.
Used in combination with steel, concrete, screeded or timber constructed roofs.
Elastaseal™ Roof Waterproofing Systems are ideally suited for refurbishing and protecting weathered, worn and damaged substrates on many types of building:
Due to the high number of possible substrates and varying conditions in which they can be found, Tor Coatings strongly recommend that a site survey is carried out to determine the exact specification required.
Elastaseal™ is on the RIBA NBS+ system, please contact us if you want us to produce an NBS Formatted specification.
Tor Coatings offer a free site survey service, and all of our Area Business Managers are fully trained and able to carry out full site assessments. A detailed and bespoke specification will then be issued.
