Basement Damp Proofing, Notting Hill
Identifying Damp
We were contacted by our client to request that we carry out a survey to a damp vault which was situated under the external pavement. Following her request our qualified damp surveyor attended the property to inspect the area and take readings using a hand held damp meter and a thermal imaging camera.
Some damp proofing had previously been carried out but this was only to a part of the room. Considerable water ingress was found to be entering some areas which was making the room uninhabitable. It was decided by our damp surveyor that the safest and best course of action would be to completely remove the existing damp proofing systems and to install a completely new Cavity Drain Membrane (CDM) system, incorporating a sump and pump, to discharge water to a place chosen by us.
Eradicating Damp
Following instructions from our client, to commence the work, our trained operatives removed the existing damp proofing materials and took them to a place for disposal. The floor was excavated and a special pump chamber installed.
The concrete floor was excavated around the edges and special drainage channels were installed to discharge water into the sump. The high density polyethylene studded Cavity Drain Membrane was installed the walls using special fittings and the larger studded membrane was laid over the floor, connecting the two the with a special floor wall joint. The pump was then installed and pipe work fitted, to discharge water to a place designated by us.
