5400m² of BTRS installed onto Woolwich Polytechnic School

5400m² of Bauder's bituminous waterproofing system, Bauder Total Roof System (BTRS), was installed onto Woolwich Polytechnic School, a refurbishment project located in London which is one of the largest boys’ secondary schools in the country.

The school has undergone several extensive renovations with the additions of three separate buildings, however, being the oldest part of the school, the main building of Woolwich Polytechnic School was ageing, therefore the school decided to request a roof survey on its degrading roof which included examining all aspects of the roof to find problematic areas in order to propose the right waterproofing solution to meet the needs of the building, free of charge.
Bauder’s area technical manager was commissioned to carry out an in-depth moisture mapping roof survey to three roof areas within the main roof using a Troxler 3216 Roof Reader. Moisture mapping scientifically verified the specific levels and locations of moisture within the existing waterproofing and identified the true condition of the roof which was then plotted, and a visual data report produced to determine the remedial action needed.

The survey concluded that the existing waterproofing system contained water to several areas with the addition of there also being some localised small areas of water within the existing original build-up. This was estimated to be in the region of 30-40% on the first roof section and 25-35% on the second. The third section of roof contained water to one localised area.

It was determined that our Bauder Total Roof System (BTRS) was the best solution to refurbish the school roof. BTRS is a first class bituminous system in terms of both quality and technology. It is robust and durable enough to withstand foot traffic along with most permanantley sited plant and is specified in applications where outstanding longevity is required, making it the perfect system for Woolwich Polytechnic School.
