floor construction

I'm replacing my suspended floor with a concrete one, and have just poured the slab. The plan now is 150mm PIR, UFH pipes, and 50mm liquid screed. The stairs are currently supported on a temporary 6x3 timber which allowed me to pour the slab straight through (picture below). The stairs need...

Hi everyone I am going to prepare and lay the concrete floor to my extension myself. I will need to run a pipe under the floor to provide ventilation to the existing suspended floor. I have already laid down hardcore and sand. I wanted to do the concrete slab first and then the...

Hey all Long story short. I've pulled up my kitchen floor and found most of it in reasonable shape except for this cross beam which is badly rotten. It was encased in damp dirt which explains things. The property was built in 1900 so perhaps this is inevitable. There is a copper gas pipe...

We are beginning a garage conversion and need to achieve a U-Value of 0.22 with the floor. The suggestion to achieve this is 100mm Celotex insulation. The existing floor to ceiling is 248cm but at the front of the garage its slightly lower at 237cm. I believe building the 100mm Celotex floor...
