Basement flooding can be stressful. Let’s take a look at the major causes of basement flooding and different methods of addressing the problem.

Why is my basement leaking?

Since basements are situated under the ground level, they are more prone to leaks and flooding. The most common causes of a basement flooding are cracks in the walls as well as the floor joint of the room. During raining season, the soil may get saturated and allow the rainwater to pass through the walls. The seeping water can get deposited near the foundation of your basement. Clay bowl effect also causes flooding of water into your basement. Clogged drains and back flow of sewage may fill your basement with notorious sewer water, which is hard to clean. Breakage of water supply lines can allow the water to pass through the walls and seep in your basement. To prevent the leaking water from walls, drains and the floor of basement, you should opt for interior waterproofing of the entire basement.

How will interior water proofing help?

Interior waterproofing insulates the walls and floor of a basement in such a way that it does not allow the water to seep through it. It effectively seals any cracks in the walls, through which water is leaking. It helps in keeping the basement clean and usable for various purposes.

What are the different methods used?

The common methods of interior waterproofing of basements are:

#1 Waterproof coating

The walls of the basement that have cracks may tend to leak water from broken drains or saturated soil surrounding it. You may use concrete coating, which are easy to apply and adhere to previously coated walls after drying. Silicon based concrete sealers are also effective in waterproofing the basement but is only suitable for walls that have not been previously sealed or painted.

#2 Sealants

Sealants are effective if there are cracks in the concrete, which allows the water to pass through it. Special sealing agents are poured in the cracks which get filled in the gaps and completely block the path of leaking water from outside.

#3 Basement water drainage systems

Sump pumps are installed at the base of your basement to prevent water from accumulating inside your house. It does not stop the water from leaking inside, but collects it under the level of the floor and pumps it out of your property. This prevents damage to the walls, floor and other structures. It can also be used in combination with various waterproof panels or plastic sheets for the walls. Even though such drainage systems are effective and useful, they may need regular maintenance. Sump pumps may not work if there is no electricity or there is a blockage in the drainpipe for eliminating water. If water is backing from sewage line, installing a backwater valve will prevent flooding in your basement.

Can I do it myself or do I need a pro?

Interior waterproofing can be done with various do-it-yourself kits if you are comfortable with plumbing works, although hiring a professional waterproofing contractor may make the task easy at your end. You may require a plumber’s help for installations like sump pumps, valves and replacing clogged pipes.
