The specification
The client required a waterproofing system that provided various finishes. Bauderflex was installed on the Energy Centre roof and the Bauder Thermofol Single Ply Waterproofing System was installed across the rest of the new building.

To comply with the Scottish building regulations, three different calculations were carried out to achieve specific U-values. One calculation was to achieve 0.18 and some areas with 0.16 with tapered insulation.

The external planter area was designed to be buried; therefore the Bauder Total Green Roof waterproofing system was most suited to this area.

Products applied
BauderTHERMOFOL U 15 V FR
This single ply membrane is lightweight and has a high-grade virgin polymer formulation. The PVC formulation ensures it is resistant to chemicals and micro-organism attack.

Project challenges
Falls were created using tapered insulation schemes as opposed to being incorporated within the buildings structure. This project paused for around 12 months due to the COVID-19 pandemic, during that time the client’s requirements changed therefore the tapered insulation design had to be revised multiple times to accommodate.

The result
Working with Architect, Main Contractor and Approved Contractor to ensure a successful installation of three waterproofing systems across the hotel extension. Bauder provided various calculations and designs, along with site monitoring and continued project support with throughout to ensure the project would be completed to the highest standard.
