Three Tips for Achieving Long-Term Results With Interior Basement Waterproofing
Interior basement waterproofing is a waterproofing technique that prevents moisture from seeping through the basement walls and floors. This method is ideal for existing construction, as it does not involve excavating the ground to install drainage systems. Therefore, it is affordable and easy to execute. However, incorrectly done interior waterproofing can fail, leading to moisture damage to the structure. With this in mind, check out these tips for achieving long-term results with this waterproofing technique.
Address the source of the moisture
Interior basement waterproofing methods work by preventing water from seeping into the structure. Therefore, in many cases, homeowners don't address the cause of the moisture infiltration. Unfortunately, failure to fix the source of the moisture can weaken waterproofing sealants, causing them to fail.
For example, if your basement is flooding due to poor grading and a lack of guttering systems, interior waterproofing methods may fail to work. Runoff and water from the roof will exert pressure on the foundation walls from the exterior. Over time, the sealants will wear off and allow moisture to infiltrate your basement.
You don't have to spend money on extensive exterior waterproofing methods. However, you can take simple measures to address moisture issues and increase the effectiveness of your sealants. For example, install gutters and downspouts to redirect rainwater away from the foundation. Also, improve the grading around the building to ensure the slope moves away from the foundation.
Repair cracks on walls and floors
Cracks in concrete basement walls and floors are a leading cause of moisture infiltration. Before applying any sealants to the surfaces, you should repair the cracks. Remember, since you don't have any exterior systems in place to keep out moisture, it may still seep into the building from outside. However, interior waterproofing sealants will prevent water from damaging the basement's interior.
When there are cracks in the basement walls and floors, moisture seeps into the cracks and exerts pressure on the concrete due to temperature changes. Consequently, the cracks widen and weaken the sealant, allowing water into the basement. Repairing all existing cracks will prevent moisture from further damaging the foundation walls and floors. It will also increase the efficiency and lifespan of the waterproofing sealant.
Apply quality sealants
Waterproofing sealants are available in varying qualities. Some can last longer and resist hydrostatic pressure better than other products. If you go for an inferior product, it will fail within a short period of time, especially if you haven't addressed the moisture problems in your home's exterior. Therefore, opt for quality sealants that can last a significant period of time. If possible, install a sump pump to relieve the foundation of hydrostatic pressure.
Keep these issues in mind when waterproofing your basement. For professional services, consult your contractor.
