Chasing cavity wall for pipes in bathroom

Postby Accountantbytrade » Thu Sep 03, 2020 1:16 pm

I am chasing our bathroom wall to run the water pipes up it (22mm). The wall looks to be a standard cavity wall made of 100mm deep blocks. I am finding it very difficult chasing this out. I am using an SDS drill and a specific chasing bit but I am finding the bricks are breaking a lot and it is not very neat. I am worried that I am digging out too deep. Is there any way I can reinforce this afterwards. I understand it should be about 30mm deep which is what I am trying to do but the bricks seem to crumble everywhere. Is there a better tool to use for this and can I reinforce it afterwards?

Thanks for your help.

Hi accountantbytrade
Suggest you use a 4 1/2 inch angle grinder with diamond blade and cut vertical slots following the line of your channel. Cuts about 5mm apart make it easy to break out but it is a messy job with the grinder.
