I have been provided the post and beam size required to replace a load bearing wall.
I am wondering what the best approach to install the post would be.
The floor is a concrete floor with a damp proof membrane a couple of inches down and a weak screed on the top of this. I was planning to use brackets, screws and plugs to hold the post in position but am worried that the screed may not be strong enough.
Therefore if i concrete the post in, which would be the best way to do this whilst maintaining the integrity of the damp proof course after the installation is complete?
Hi jamesmitchell You should cut a hole in the existing floor and form a foundation below floor level for your post. With careful breaking you should be able to expose enough of the existing DPM so you can bond a skirt DPM around your post. You should have building regs involvement for this job. Regards S
Hi jamesmitchell Suggest you form a concrete foundation, probably with a base about 50x50cm, this could be smaller if the subsoil is solid. This can be a pyramid (with the top cut off) in shape, the top can be at your existing DPM level. Reform the DPM and use a post base bolt down bracket to form a pocket for your post them make good the floor. Regards S
