Folks I need some advice. We have had some work done by a cowboy whilst I was out of the country and he will not be repairing the problem.
Anyhow he has put the shower waste outlet through the joists of the bathroom. The joists are 170mm x 55mm and he has cut 61 mm holes in the upper third of the joists. A telephone call to a building surveyor confirmed my suspicions that the strength had been compromised especially considering the fact that these joists are also carrying a bath and the holes are aprox 300mm from the edge of the bath.
I am happy to carry out the repair as I was planning on steel plates either side of each joist which is drilled and bolted. What I wanted to know was:
1. How thick should the plates be?
2. How far either side of the hole centre should the plate run?
3. I was planning on a plate with a 'U' cut out of it to allow for the pipe work. How should the bolt holes be located.
Thanks
