A robust and high performance waterproofing solution has been specified from Sika-Trocal for the new £30 million state-of-the-art student accommodation at Bangor University in Gwynedd.

The St Mary’s student village development at the university has been designed by architect FaulknerBrowns and includes five new residential blocks or townhouses, along with a café and bar, sports and fitness centre, a shop and launderette facilities. For the new townhouses, which are set around a ‘village square’, specialist contractor Weatherwell Roofing turned to Sika- Trocal for a cost-effective, hassle-free application.

The versatility of the Trocal Type S waterproofing membrane ensured that any detailing, such as capping vents or curved cone features were achieved and met the architect’s aesthetic vision. To provide a neat finish, all edge cappings were made from Sika-Trocal Metal rather than standard powder coated copings.

The Sika-Trocal Type S membrane was laid over the insulation onto the timber deck and securely fastened using Sika-Trocal’s innovative laminated metal disc system. This system sees the membrane and insulation mechanically fixed to the roof in a single process, ensuring a fast installation minimising components required and reducing overall project costs.
