Exisiting DPC holes


Postby shredder91 » Wed Jun 10, 2009 2:04 pm

Hi,

I have a 1920's semidetached house, whcih by the looks of it had a bit of a scam artist do a DPC on the house a while before we bought the house. Holes were drilled, only half were plugged and we don't know if any treatment was used (although there was half a barrel of chemical DPC in the back garden)

To be honest, we have left this job as a can wait, but we are starting to get a bit of internal damp.

We are going to get the inside replastered anyway, but my question is, could I use the exisitng holes drilled into the walls to apply the DIY DPC cream?

shredder91,
Yes but I would suggest you hire a pressure injection machine and inject silicone liquid DPC.

Did you not get a 30yr DPC guarantee when you bought thehouse ?
Replastering internally alone will not solve damp problems.
Walls need to be injected both internally and externally, and internally a sharpsand render with silicone additive applied from floor to 1mtr high.
