Today in modern buildings, bathrooms are not just the spaces for freshening up, but are more visualized as personal spaces to get refreshed and also rejuvenated and as a matter of fact, a substantial amount of time and investment is put in to make-over or build bathrooms as per individual's choice.

But the whole visualization gets disturbed when such bathrooms look damp and get frequently exposed to water penetration through walls, window joints, floors etc. Failure to waterproof bathroom not only hampers the look of your flat but also it could lead to major problems. Though wet areas occupy less than 10% of the gross floor area, the annual maintenance cost for such bathrooms area can range from 35% to 50% of the total maintenance cost depending on the type of facility.

Normally the materials and components used in bathroom to make its floor, wall, architectural finishes etc. including service pipes and sanitary fittings are susceptible to natural movement and as a result, the materials made of clay and tiles could increase in size affecting the joints and causing the tiles to shift. This results into the leakages and dampness on the walls. So, waterproofing of the bathroom is one of the most important parameter and we have to ensure that the waterproofing systems are applied correctly and carefully. Wrong selection and incorrect application causes the premature failure against leakage and rectification becomes much costly and time-consuming and annoying too.
