Stop basement water intrusion to keep your basement dry, safe, and habitable.

What is Interior Basement Waterproofing?

Interior Basement Waterproofing addresses water intrusion inside the basement from all 3 points, such as the wall leaks. the cove joint ( footing, wall, and slab joint where all 3 connect) and the under-slab pressure. 

The process involves installing an interior drainage system that captures wall and floor seepage before it reaches the basement floor. This water is then redirected to a sump pump system to funnel water away from your home. Sealants and coatings are also applied to the interior wall and floor surfaces to block any remaining moisture. 


It is a strong and durable waterproofing system that will help hydrostatic pressure build up and prevent a wet basement. It ensures moisture is kept outside and won’t cause further damage. This allows you to utilize your basement for storage or additional living space.

What Causes Water to Get Into Your Basement?

Experiencing water in your basement can be overwhelming and stressful, especially when you don’t know where it came from. The following are the most common ways water enters basements.

Why is Interior Basement Waterproofing Necessary?

Interior basement waterproofing is not just a preventive measure; it’s a smart investment to maintain your home’s structural integrity and value.  This process effectively tackles water intrusion, providing a durable solution to manage moisture and prevent water damage.


There are several key reasons why it is important:

Signs You Need Interior Basement Waterproofing

Many homeowners experience problems with moisture and water in their basements. Ignoring these issues might seem easy, but it can result in significant problems for your home and your family.


Here are some key indicators that suggest a need for interior basement waterproofing:

Knowing these common causes can help you identify and address the problem before it escalates, saving you from costly repairs and preserving the value of your home.

Components of LUX Interior Basement Waterproofing

Using advanced engineering techniques, interior basement waterproofing from LUX Foundation Solutions works by creating an effective barrier that prevents water from seeping through the basement walls, keeping it dry and safe. Our installation process includes the following:

1. Excavation

The concrete around the area to be treated inside the basement is broken up to create a trench approximately 6 to 18 inches away from the foundation wall. This is the first step in the process, allowing the installation of the drainage system and sump pump.



2. Interior Drainage and Sump Pump Installation

An under-slab drain system, such as a sectional or perimeter drain, is installed in the trench created during the excavation. Then, a layer of ¾ clean gravel is put over the drain system to gain maximum drainage to the drain. The system directs any water seeping into the basement towards a sump pump, which pumps the water outside and away from the house.


3. Crack Sealing and Repairs

Any visible cracks or damages in the basement walls or floor are sealed using synthetic cement epoxy or polyurethane and repaired to prevent water seepage. This is a critical step as water often finds its way through these cracks.


4. Waterproof Membrane or Vapor Barrier Installation

A waterproof membrane or vapor barrier is applied on the exposed interior walls of the basement, acting as a shield against any moisture that may seep through the walls.


5. Concrete Replacement and Quality Check

Then, a layer of concrete is installed over the exposed trench, and a thorough quality check is performed to ensure the system is completed as designed and engineered and all components of the waterproofing system are functioning properly. The system is flood-tested to simulate normal conditions as the final step.


6. Installing a Dehumidifier (optional)

The final step is optional but recommended, particularly in damp climates. Installing a dehumidifier helps to control humidity levels within the basement, keeping the environment dry and preventing condensation.

When should I consider interior basement waterproofing for my home?

Consider interior basement waterproofing for your home if you notice signs of basement water problems like dampness, water stains, or mold. If cracks appear in the foundation walls or floor, leaks can occur during heavy rainfall. Additionally, if you plan to finish or renovate your basement, it’s wise to address waterproofing beforehand to protect your investment. 

Interior waterproofing is a proactive measure to manage existing water issues and prevent potential damage to your home’s foundation. Consult with LUX professionals for a thorough assessment to determine the most appropriate time to undertake this waterproofing project based on your specific circumstances.

Is interior waterproofing effective?

Yes, it’s an effective solution for managing and preventing basement water intrusion. While exterior waterproofing addresses the issue at its source, interior waterproofing is a practical alternative that can effectively control water already entering the basement.

The effectiveness depends on the specific circumstances and the chosen techniques. Consulting with professionals, such as LUX Foundation Solutions, can help determine the most suitable interior waterproofing methods for your home based on its unique characteristics and the severity of the water intrusion issue.

Why is water coming through my walls when it rains?

Water coming through your walls during rain may be attributed to various factors. The most common reasons include cracks in the walls, gaps around windows or doors, deteriorating mortar joints, or insufficient waterproofing. Heavy rainfall can saturate the soil around your foundation, increasing hydrostatic pressure and forcing water through any openings or weaknesses in the walls. 

Poor exterior grading, lack of gutters, or clogged downspouts can also contribute to water pooling near the foundation and seeping into the walls. Identifying the specific cause requires a professional inspection. Contact our LUX team, and we will assess the issue, determine the source of water intrusion, and recommend effective solutions to prevent further wall leaks during rain.

Can water in the basement damage the foundation?

Yes, water in the basement can damage your home’s foundation. When water accumulates around the foundation, it creates hydrostatic pressure, exerting force against the walls. Over time, this immense pressure can lead to cracks, leaks, bowing walls, and structural damage. 


Water infiltration can also compromise the integrity of concrete walls and contribute to the deterioration of building materials, such as wood framing and insulation. Additionally, prolonged exposure to moisture creates conditions conducive to mold growth, further impacting the foundation’s indoor air quality and structural elements. 

Promptly addressing water issues is crucial to preventing potential damage to the foundation and maintaining the overall stability of your home. Contact us today so we can provide professional assessments and effective solutions to mitigate water-related risks and protect your foundation.

Can I waterproof my basement myself?

Waterproofing your basement is a complex task requiring professional expertise and specialized equipment. While some DIY waterproofing products are available, achieving effective and lasting results involves thoroughly understanding your basement’s specific issues and applying appropriate solutions.


Professional waterproofing experts have the knowledge to assess the unique characteristics of your basement, identify the root causes of water intrusion, and implement tailored solutions. They also have access to high-quality materials and equipment to ensure the job is done correctly and offer warranties on their materials and workmanship.

Attempting to waterproof yourself may not address the underlying problems adequately, potentially leading to ongoing issues and costly repairs. Contact us now, and we will provide a comprehensive and effective waterproofing solution based on your specific needs and the condition of your basement.
