I have a problam with a damp floor...but do not want to tank it with Sika or simlar as the minimum depth is 35mm and I have extremely low head room.. The dampness is just dark patches rather than flooding....is there a cheap and easy system that will not add a great depth to the floor? Make a solutionj that allows the floor to breath? - not the best option I know...I am thinking of putting tiles on the floor.
