Hi,
Thank You for your help/guidance in advance.
We live in Victoria. In year 2023 we got rid of carpet flooring and decided to grind and seal our house foundation flooring. However, the flooring is now flaking around one side of living room due to moisture in the slab.
Any suggestions how we can fix this and if we can reseal it with something waterproof?
Thanks
Hello @SunnyB
Welcome to the Bunnings Workshop community. it's sensational to have you join us and thanks for sharing your question about your concrete floor.
It appears that you have water coming through your concrete floor. The water that is coming through is probably flowing from outside your brick or concrete wall. The water is exerting hydrostatic pressure on the seal of your floor and is causing it to lift away. In order to fix this issue. The water from outside must be addressed. This means that the wall outside must be sealed first to prevent water from travelling into your concrete floor.
If your wall is a little bit underground, it must be dug up and a water proofing membrane like Gripset Betta 4L Bitumen Rubber Waterproofing Membrane must be applied. Once the wall has been treated your floor should start to dry out. When it is completely dry that is the time you can seal it back up again. However, if you find that it is too difficult to gain access to your outside wall, I suggest engaging the services of a trade's person to do the job for you.
If you need further assistance, please let us know.
