Rising damp is a threat against waterproofing toilet floor efforts and systems. This is extremely usual in Singapore where moist proof courses are not installed however it can be repaired if you understand how.
Weaknesses against damp
Like poaching an egg this is not something you would trust to people who don’t recognize what they are doing. The remedy is to cut out a straight slit throughout the bottom of the wall surface and complete length of the wall of course this needs excellent treatment and for evident reasons you do not do it simultaneously. You then fill up the slit with high thickness concrete. This is known as a sloof and will halt water rising inside the wall from the ground underneath.
The walls of a lot of structures nowadays have reinforced concrete upright columns with strengthened ring beams along the top that supply the strength. The spaces between the columns and beams has an infill of light concrete blocks or soft neighborhood red bricks with a skim of hard concrete on the surface. The strengthened concrete is usually extremely inadequately made with splits and hollows in it and the infill resembles blotting paper (sorry you may not remember that, like a sponge).

Alright so we have discovered the reason, how do we deal with it? The standard technique is to utilize a skim of greater density waterproofing cement yet this is not a method I advise. This type of waterproofing film is really breakable and can break. On a surface exposed to sunshine the surplus surface area heat will break the concrete skim away from the wall surface under permitting water to go into which can travel between the concrete skim and the surface under.
