If you are a homeowner, you would probably agree that there is nothing worse than a wet basement. This problem often starts with tiny signs like small cracks, which in the long run are signs of an even bigger problem. From damaged structures to a platform for mold growth, water in your basement is hazardous. In the long run, basement repair can cost you fortunes. However, if you are planning on selling your house, an excellent basement waterproofing investment could earn you a 30% ROI.

Fortunately, basement waterproofing services are easily accessible. Today we’re going back to the basics of basement waterproofing. Take a look at some tips that can help you maintain the structural integrity of your foundation and basement.


Interior waterproofing is the cheapest and the easiest compared to other basement waterproofing methods. This method involves being on the lookout for cracks and holes in the basement. Areas such as floors, walls, windows, etc. are the most affected. These areas should be sealed and kept dry. Sealants are not only active on cracks and holes but also affordable.

The idea here is to lower humidity to prevent condensation, and sealants do the magic. The sealants create a waterproof barrier on the interior and to avoid moisture from sipping through.


The monster problem with moist basements is always on the outside. Therefore, to be able to uproot the problem, it is vital that you do basement wall repair outside the cellar. The process of exterior waterproofing is often complicated and calls for the intervention of a professional.

The process involves digging out soil on the foundation area. This process is labor-intensive and also requires the use of specialized machinery. Once all the dirt is displaced, the application of water sealants on the exterior walls follows. The sealant is long-lasting. Typically, it lasts for as long as the building exists. Preferably, you should do exterior waterproofing during construction.

A sound gutter system also comes in handy here. If installed properly, a proper gutter system will direct water away from the basement walls. However, if not installed properly, they do more damage to the basement walls. Always ensure your gutters are not clogged up, and they are correctly set up to direct water away from the basement.


For your basement waterproofing repair to be successful, you should first take care of the drainage system. The drainage system on the inside collects water from your foundation and directs it away from your basement.

A weak drainage system, on the other hand, is the biggest source of moisture in the basement. The first step towards avoiding this is by ensuring that the drainage system directs underground and rainwater away from your basement foundation. Depending on the type of soil on your basement foundation, there are different types of drainage systems to explore.

Carefully study your home surroundings. Ensure the ground is sloping away from your basement foundation. If not, a sump pump comes in handy. It helps in pumping water from the inside and directing towards other areas.

However, always try and ensure that the system is not over-reliant on power. It is important as a cost-cutting measure and also helps in ensuring continuity of operation even in the absence of power. Setting up such a drainage system may not be a walk in the park. It would be wise to get a professional do it for you.


Weak drainage systems, improperly installed gutters, condensation, and the soil type are some of the leading causes of moist basements. Wet basements are not only uncomfortable but also hazardous. Basement repair can also be time-consuming.

Adopt preventing measures earlier on. This could include interior and exterior wall waterproofing as well as basement waterproofing. Always ensure that your drainage system is functioning correctly and never overlook even the smallest warning signs such as cracks on the walls. If you happen to notice them developing, contact a contractor to conduct a detailed inspection and recommend the best way forward.
