On one side, dirt has been piled up above the level of the barge boards and a concrete path laid on top, right up to the house leaving nowhere for water to drain, and completely blocking underfloor ventilation. This caused a minor termite problem which has been dealt with. However, to deal with it in the long term, we need to get some ventilation back and prevent pooling of seeped water from the path under the house (termites love a damp environment). I was thinking of getting a concrete cutter and cutting the path say around a 100-150mm away from the house, removing the concrete and digging down (about 200mm) to expose the barge boards. Remove them to completely open up the underfloor area for ventilation. I could then fit some form of grate over this that allowed ventilation. I then need to fit some form of lip to the cut edge to direct rainwater away from the grating and to a drain. Does this sound reasonable? What would you suggest as a way to direct the water to the drain? TIA cheers Gary 2 3747 That's very helpful, thank you. I was mostly interested in knowing if a spoon drain requires a specific slope, but I appreciate the extra information. 4 3922 because its not being managed properly. Also "properly" is too broad and too subjective a term to be able to pinpoint a single event as not being managed properly.… 1 2729 |
