Hi chaps,
I'm looking at taking on a big job over the coming weeks - DIY tanking to my cellar/basement area.
Now, I've had a survey so far and the guy seemed very knowledgeable. The house is very old with no DPM or DPC.
Unacceptable moisture readings are through the floors and large sections of wall throughout the cellar.
I'm waiting for the cost in the quotation and expecting it to be in the thousands. The guy suggested a membrane or sheeting system over a cementitious system, as a small gulley or channel will be fitted to drain the water away. He said with the cementitious system, the pressure of the water or hydrostatic pressure, can build with nowhere for the water to go, so it finds its way out elsewhere. Which research suggests to be true.
Now my question is, do I go with his advice and fit my own membrane system (I need to find some good systems if anybody can recommend them??) or use the cementitious system?
Also, as I'm going to construct new partitions on this level, so if I'm applying some sort of substrate to the floor, how do I fix studwork??? Will this bridge the substrate I have applied and leave passage open to moisture rising?? Help appreciated
