What do you guys use to cover expansion grooves in concrete slabs, safety flooring is going over the slab, can you screed over them?
no you cant screed over them. Some manufacturers say you can but they say this in a way that YOU as the proffestional has to decide if they are ok to skim over. So ball back in your court. What you use to go over them (but leaving them working) depends on what your installing. Gradus , Quantum etc do strips for safety flooring that you can weld to .
Ive think ive seen the type you mean in mothercare where the lvt has been fitted up to them, there about 100mm wide with ribs in the middle part Cheers
We just did two jobs over powerfloat with expansion joints. In the changing rooms, with c&c, we used isolator membrane. There were loads of expansion joints, so the strips would have made it look like a patchwork quilt.
