The existing bitumen roofing had split in many places and was allowing water ingress into the building below.
We proposed the application of Remmers MB2K to resolve the problem. This highly versatile waterproofing product can also be used as a liquid roofing material.
Preparing the roof with high pressure jetting
Initially the roof was prepared by method of high pressure spinning jet to remove organic matter and provide a clean and suitable surface for the new liquid roofing to adhere to.
Cracks in the roof were dressed using a vacuum controlled diamond saw prior to sealing using a polyurethane jointing compound. These were then subsequently stripe coated and reinforced with an additional coat of the liquid roofing material.
The same bandage reinforcement was installed as part of the liquid roofing specification at the interface with the adjoining wall as this point presented the greatest point of potential movement.
Applying the Remmers MB2K liquid to the roof
Remmers MB2K was then applied to a thickness of 2mm by method of trowel and back rolling to provide a slip resistant finish.
Because Remmers MB2K is a completely solvent free liquid roofing material it did not present any problems adhering to the aged bitumen. Solvent based materials can ‘liven’ the bitumen, which can be detrimental to adhesion.
The seamless liquid applied waterproofing membrane will provide a long lasting solution.
