Hi All
The builders are back tomorrow so I need an urgent answer to a question if you could please...
We've brought the build out the ground on foundation blocks. As I want a space under the floor, ive put DPM around the outside of the blocks to stop and damp coming through into the voide... as I did this i lapped it over on top of the blocks and put bricks on it to hold it in place whilst I've back filled the outside. Today, the builders put the inside blocks up and have made a great job... but they also put one row of bricks on the outside face straight onto the DPM????...
Unlike DPC that has diamonds in it to help it key and grip, this stuff it 1200 gauge DPM thats smooth.
I did expect them not the key it in if I'm honest or if they did, only 10mm or so... but they have put it the full way under the outside course... what stops the bricks 'slipping' off in future?
or am I worrying too much?.. it may have been better if they had a bit of weight on it if they had done 3 or 4 layers.. but just one layer?.. it's hardly pushing it into the blocks below?.. so very little key?.. and when they do build on top and it crushes a bit, does that further break any bond there may be???...
