Methods of basement waterproofing
There are some techniques and methods which one can adapt to prevent water penetration in the basement. They are used to redirect water that has already penetrated the basement and its foundation.
Interior waterproofing methods are so far the most convenient and economical. In interior waterproofing, the holes and cracks present in the basement are Sealed. Filling the cracks and making them watertight is an essential step because it helps keep the basement dry and prevents humidity which can cause many problems. Interior waterproofing is a better option for small cracks and leakage. It is not very practical for big cracks.
Interior sealants or waterproof sealants are used for this job. They restrict condensation. Coatings of these sealants on the walls and floor act as a waterproof barrier that prevents seepage. The homeowner should keep in mind interior sealants and waterproofing is good for preventing moisture and humidity inside the basement to restrict concrete spalling. It is an important step, but it does not solve the main issue causing the problem.
Exterior waterproofing can save the house from structural damage caused by moisture. It is an excellent way to get rid of the problem because it addresses the underlying issue and lasts longer. Well, exterior waterproofing is expensive as compared to interior waterproofing.
The process involves digging down the Outside wall to the footer. Here basically, the soil from the foundation of your house is excavated. After the footings are excavated, the walls are power washed and dried. Afterward, the walls are sealed with a liquid rubber compound or a waterproofing membrane. At last, the new drainage (footer tiles) are placed. The water can be drained through sump pumps. The sealant used in exterior waterproofing is usually polymer-based. The polymer-based sealants can be directly sprayed on the wall.
One thing the residents usually don’t consider is the impact of gutters on their house. While talking about exterior methods -gutters, if installed correctly, carry the rainwater away from your house. But if they are not cleaned and installed in the right way, they can cause severe problems to the foundation of your house. Make sure your gutters are clean, open and have the Right downspouts, which carry water away from the foundation of your house.
If you are looking to move water away from your house rather than blocking it, water drainage is the solution. In this method, porous pipes are installed in the walls and floor of the basement. The pipes absorb and collect water into a sump pit system. Then a sump pump system takes this water away from the house.
All these methods are effective, but the solution also depends on your house structure, place, and situation. So it’s better to consult with an basement waterproofing expert in Minneapolis to choose the best option for your house.
