spyder880: Before we discuss damp proofing, what is dampness?

Dampness occurs in a building when the ground water under a building starts to find its way up from the ground to the under of the house, affecting the foundation and lower portion of the house negatively.
Dampness occurs because of capiliary action in areas prone to underground water, like those living in some parts of Rivers, Lagos, Bayelsa, Delta, Abia and other low lying parts of this country.
The negative effects of dampness includes the weakening of floors, wetness which might affect properties and furniture, peeling of paints and spoiling of wall decorations, especially lower walls.

We try to mitigate against the capiliary action which brings about dampness by placing a thin layer of cellophane (nylon) covering over the filled foundation, then we cast the DPC. This will tend to block the seepage of water from the ground to the main building.




Hope I answered the question you were asking?

Spyder, I was discussing with a friend about the foundation of his new house. He got it impressed on me that he's looking forward to a "solid" foundation with a wire mesh. But, I found this unnecessary as a poorly compacted foundation would still settle even with a wire mesh on it. Cellophane covering as you've been doing in PH makes more technical sense to me. Do you think they're right with their idea of a "solid" foundation? Where is really the place of wire mesh in building foundations?

We return to this building this week. We are here to continue the project. We moved in to hang a suspended slab (decking) on this house. Expect pictures of work progress, details and more as we move forward.
