I have a basement with block walls that has leaked in th past. The leaks in the past enimatedat th juction of the slab and the wall.The wall has been thoroughly scoured with a steel bush and painted with the usual sealer [drylock I think], a particularly heavy coatings have been applied to where the leaks emulated from. In over two years now there have been no more leaks.
Most of the wall is below ground level. As a belt and braces approach Iam going top redo the sealing process. ,apply plastic sheeting ,furring strips with foam insulation between and then beedboard [painted]
Question 1 Is the foam insulation necessary ?
Question 2 Does the plastic sheeting go behind the plastic or infront of it ?
Any help appreciated....mjh
