Cavity wall clearing

[Stevecc]

Does anyone have any expericence of cavity wall clearing

I have found the cavity walls have quite a bit of sand in them. The sand bridges the DPC and in some cases goes above 400mm above DPC. Aslo as you go down the wall it turns solid mortar.

I was thinking of trying to get a rotary mutitool in the cavity to break up the mortar.

Also concern about reinstalling the brick. Will the brick take the load, won't the morat shrink a bit and the load taken by surrounding bricks

Thanks

Cut out some coring holes. You don't need to take out the whole course.

Yes trying to keep the brick taken out to a minimum

Stevecc, good evening.

Suggest you try some forward planning? get a snake camera. bore into the cavity, locate areas of issue, work on them ignore the rest of the wall.

Can save some tile and effort.

Ken.

Thanks Ken

I have a snake camera and I can see that where I am going next. So far it seems all the wall.

At least 4 bricks (2 per course) every 4 bricks.

That's your minimum
