You can try but, quite honestly, that probably won't fix the real problem. Sealers and waterproofing paints only mask symptoms and can even make problems worse by actually sealing in moisture. They don't treat the cause. Even if you only have one wall crack and minimal leaking, if not treated properly and early, you can expect more cracks and problems to develop. The reasons need to be identified and repaired.

Epoxy is highly durable, it's also very rigid. It doesn't tolerate extended movement well and this fact can hinder your basement (and home) from its natural tendency to expand and contract. As you'd guess, a rigid-setting material like epoxy has the potential to create additional cracks and structural failures. Most important, epoxy is best used in dry-condition environments. Its strong adhesion properties are reduced if used on moist or wet surfaces - like a leaky basement. It's not considered a true "water-stop" material like polyurethane is, but some companies and do-it-yourselfers use epoxy.

The following are all signs of a leaky or damp wall:

• Musty odor
• Mold & mildew
• Cracked walls
• White, chalky substances or damp spots on the walls
• Peeling paint or warped wood
• Dry rot or furniture damage

The modern ways of waterproofing are Liquid brush applied solutions which can be bitumen based, acrylic based, PU based etc. and Pre formed Membranes which are loosely laid or torched or self-adhesive membranes. Please refer to the product link for more information on the individual solutions.

After application of Liquid applied membranes and / or Pre formed membranes, screed in the required slope is laid on top of the waterproofing membrane. Please refer to the product link for more information on the individual solutions.

Pitched concrete is done in parts and it creates lots of joints within the slab. Chances of leakages increases from these joints. This calls for waterproofing to avoid leakages from these joints.

A landscape area requires to be watered regularly, with pesticides and fertilizers / manure, etc. For this a highly robust specification must be drawn up. In addition to this the load that it puts on a RCC slab will be extra, which has to be catered for in the design itself. Depending on the kind of vegetation being planned, the barrier membranes installed, must be able to mitigate root growth that can be very detrimental to the roof / balconies slabs and walls.

The overall thickness of the waterproofing system will depend on the landscape filling. However waterproofing system thickness is 15-20 mm.

Pipes portions that will be in contact with the walls, must be wrapped around with a two-sided tape that will adhere permanently both to the pipe as well as the grout. This detail will eliminate any water entry in the bathroom’s interior.
All holes through which plumbing pipes are fitted must be grouted properly, not with a cement-sand mortar, but with a free-flow, non-shrinking cementitious grout that will set and slightly expand in the gaps.
After this waterproofing should be done right up to the top of the ‘splash’ areas in bathrooms, if not up to its ceiling. A cementitious-acrylic membrane, applied in the walls and sunken portion is the best specification, as it is elastomeric and can stretch up to 50% that takes care of cracks in the area that may move.
This system can be applied to any wet area in the building such as wash areas, kitchens, overhead or ground water tanks, ground, etc.

Before monsoon, ensure that all drains are cleaned. Provide a proper slope of 1:100 at least, with a mortar mixed with PMC coating. It helps in roof waterproofing repairs for home. This protects your terrace in just 2 easy coats. It is a UV resistant coating, so can be left exposed to sun without any screeding. Itsalso foot trafficable and best part is that you need not break your terrace as being done traditionally with brickbat coba method.

To create the leak free garden on terrace, normal waterproofing methodologies are not sufficient. You must put heavy duty, impermeable membranes under the garden with proper drainage systems to channel out the excess water from it.

Pitched concrete is done in parts and it creates lots of joints within the slab. Chances of leakages increases from these joints. This calls for waterproofing to avoid leakages from these joints.
