Grange Park Opera - Waterproofing

West Horsley Place, Surrey

One of our largest structural waterproofing design and installations, of a cavity drain membrane system with drainage channels and sumps & pumps was carried out in surrey in 2016.

Traditional Builders RJSmith & Co. constructed a magnificent 700 seat, purpose-built opera house, modelled on La Scala in Milan, and we were pleased to have been contracted for the design and installation for the waterproofing of the areas below ground.

With our consultant at the time and adhering strictly to BS8102:(2009) we designed a system to cover over 350m2 of the entire below ground structure, such as the orchestra pit, plant rooms, technicians’ rooms and the storage and prop rooms.

After being given the go ahead, we supplied and installed Wykamol CM20 cavity drainage membrane to all below ground floors with the adequate drainage channels and Wykamol CM8 cavity drainage membrane to the walls along with the necessary Edincare pumps and extra services and sundries.
