Why Choose Bitumen as a Roof System?
Sika's bituminous roof solutions come in two different forms: reinforced membranes and also hot melt structural waterproofing. Our bituminous membranes are formed of a reinforced; polymer modified bituminous compound, providing a high quality roof waterproofing solution. Our hot melt structural waterproofing system is an outstanding system, it is BBA certified to last the design life of the structure to which it is installed. Both bituminous technologies are robust waterproofing solutions, and have their own individual system features and benefits. However, with any roofing specification, it's important to understand where each of these technologies are most suitable and our technical team can support with bespoke design advice to suit the individual project requirements.
