Hi all,
In my house, a gas boiler supplying ducted air was removed (and never made good).
The boiler was sat subfloor level. There is a 2 foot by 1 foot (approx) hole, about 2-3 inches deep. At the bottom, the hole is not concrete, or flat - it looks like a metal sheet, with some ridges, and a couple of small holes in.
Any ideas on the best and easiest (i.e. cheapest ) way of filling this hole?
