Damp Proofing

How can I remedy a damp garage caused by bricks below DPC

Anonymous user 09/03/2024 - 3.24 PM

Hello I'm wanting to use my garage as a wood workshop however I have a damp issue at the bottom of the walls and it makes everything that is touching the floor and up close to the walls mouldy/rotten. My garage is single-skin brick built in the 60s and the problem is that the DPC is about 70mm higher than the concrete floor inside, therefore all the bricks below that level are understandably damp and transfer moisture inside. I'm looking for any ideas how I could go about fixing this issue without breaking the bank. It doesn't need to look amazing as it's only a workshop but I do want to make sure it does the job properly. Many thanks

Raise the inside floor above the dpc and if possible concrete it with a Dpm below concrete

Yes I suggest screeding the floor ontop of a damp proof membrane Also potentially Bayern the walls and insulate between them plasterboard over as you only have 4in walls

Simple solution is to waterproof render the brick/s below the DPM. Use a render made up of Travis Perkins plastering sand and ordinary cement in a ratio of 3:1 with a mortar waterproofing additive. Make it 15mm thick minimum, ensure it bonds to the floor well . This is a very common issue.

Tank it with KA tanking slurry (2 coats crisscrossed) then render with two coats sand cement with Sika waterproofing agent added Then skim it, be a lovely job
