I am building a porch - the first project of this type I have undertaken. I have been using this site for advice and have got as far as having poured the floor slab. Currently I have the DPM protruding up on all sides. One side abuts the garage wall and one the kitchen wall. The slab is about one brick lower than the damp proof course of the house/garage.
The DPM on the exterior walls will go into the brickwork, but what to do with the other 2 sides? Do I glue it to the brickwork of the kitchen/garage or cut it off please?
Many thanks for your advice.
Regards
