Back To School
Bolton Corporate Property Services along with an Architectural practice in Bolton requested our services to provide a solution to solve a long term problem with rain water penetration to the external elevations of a Victorian school in Horwich.
Following external masonry cleaning and re-pointing the existing perished internal wall plaster was removed in its entirety totalling some 350m2; the exposed masonry was then cleaned, and lined with a high density cavity drain membrane containing a fused welded mesh on the internal face.
Insulated plasterboards were then applied followed by a skim coat of plaster; this encompassed new joinery to match the existing, all of which was then decorated to blend in with the existing school colour scheme.
As the project was ahead of the allotted contract duration, a further storage room was added; undertaking the same specification as aforementioned, this was also completed within the required time frame.
To the exposed North facing front elevation of the school, a siloxane coating which penetrates into the substrate to form a polymer silicone resin (thus forming a water repellent barrier) was applied.
This coating remains permeable to water vapour, so allowing the structure to breathe but is undetectable once cured.
The Victorian school external elevations are now waterproofed using 21st century techniques resulting in no visual changes apparent from when it was built in 1896, which is just what the client wanted.
