A Yeovil client contacted us with a damp issue to a small section of wall from their kitchen to an extension.
The symptoms presented where a combination of stains at approximately 1.8m and some peeling paint, a Protimeter was used to test the wall and high meter readings where recorded though in a sporadic pattern. There was also further staining above the kicthen window which was clearly as a result of penetrating damp. A written report with a quotation and specification was provided and we where asked to complete the works.
The external elevation was treated with an external water repellant called Enviroseal http://www.wykamol.com/enviroseal-masonry-water-repellent and any visible holes in the mortar lines filled.
When the internal wall was stripped of plaster it was found that when the extension had been built a bagged plaster known as Hardwall had been used and this had allowed for both ingress from the external wall and from a floor bridge. As a belt and braces approach we applied a tanking slurry, sand/cement render and finished with a top coat skim plaster.
The original quotation price was not changed and the client was presented with a dry wall.
