| 1400835 | 2015-05-17 08:23:00 | explain please. do you mean that the ground cover interfering with ventilation under the floor ? or the ventilation will take away any remaining moisture? Both things, Polythene sheet + venting is a good practice to take rising moisture away, out from the subfloor space. Does that make sense? |

| 1400840 | 2015-05-17 21:10:00 | Mould created from moisture pooling on the polythene especially round the edges of the house can and has rotted the ends of joists, plates etc. In one place I fixed they had a water leak which they didn't know about for ages, this was in Canada (no water meters) the water couldn't escape into the ground. |

| 1400841 | 2015-05-17 23:16:00 | What would you recommend for underfloor insulation, for a 1960's ish house where the ground under the house gets wet in winter, especially after hard rain ? Solid Foam insulation that gets wedged between joists, or the plastic-wool type of insulation that is just stapled in place ? I was thinking the solid foam insulation might help keep some of the dampness out ? Or could it eventually trap the dampness in between foam & floor? |

I recommend fixing the water running under the house problem. Divert it, drain it, whatever is the issue that it gets there in the first place. Hot air rises, putting plastic, polystyrene or whatever under your floor is a silly idea, and yes it does hide the pipes and stuff, a right PITA to have your plumber get at things, and yes, will cause water to puddle. Solve the problem, not the symptom. |

| 1400843 | 2015-05-17 23:52:00 | Ive dug an open drain around the house, that stopped alot of the water issues under the house. I'll never stop it all, the area in general has water & drainage issues (North shore clay) |
