Morning
We have constructed a drain below ground using concrete blocks and cement mortar.
We would like to seal the bottom and the sides of the drain to prevent water penetrating through into the concrete structure.
Which material would you recommend to do this ?
I was thinking about either general purpose bitumen paint or a liquid damp proof membrane.
Cheers in advance.
