Interior Waterproofing

Waterproofing a basement from the interior is the best option for most homes because it is more affordable and less intrusive than excavating on the outside. Digging a trench around the inner perimeter of the basement floor, building a drain, and adding a sump pump are all parts of an internal drainage system, often known as a French drain. Our basement waterproofing system diverts water from leaks in the walls and where the floor and walls meet to a sump pump that removes the water from the basement using a buried drainage channel.

Exterior Waterproofing

A French drain is often installed underground, and polymers and membranes are applied to the exterior of the walls. Sometimes both techniques are used to waterproof a foundation from the outside. Exterior drainage efficiently waterproofs a basement correctly, but costs are involved. The cost and likelihood of blockage are the two main drawbacks. First of all, excavation is pricy and very disruptive. Exterior drains have the additional drawback of being prone to clogging, which may result in a flooded basement.

The source of the issue and your budget will ultimately determine which basement waterproofing option is ideal for you if your property exhibits indicators that the basement needs waterproofing.

Basement Waterproofing FAQs:

Basement Waterproofing FAQ (Frequently Asked Questions) is a comprehensive guide that aims to address common queries and concerns related to basement waterproofing. This resource provides valuable information to homeowners, contractors, and anyone seeking to understand the importance, process, and benefits of basement waterproofing.

Will basement waterproofing fix existing water damage in my basement?

Basement waterproofing is primarily aimed at preventing future water damage rather than fixing existing damage. While it can help mitigate the risk of future leaks and moisture problems, it may not directly address the damage that has already occurred. If you have existing water damage in your basement, it is important to address it separately. The specific approach to repair and restore the damage will depend on the extent and nature of the water damage. It may involve removing and replacing damaged materials, drying out the space, addressing mold or mildew growth, and implementing appropriate repairs or renovations. It’s recommended to consult with professionals experienced in water damage restoration to assess the situation and determine the necessary steps to rectify the existing damage.

What are the common causes of basement leaks?

Common causes of basement leaks include poor waterproofing, cracks in foundation walls, faulty or insufficient drainage, plumbing leaks, poorly sealed windows or doors, subsurface water, basement window wells, and condensation. These issues can allow water to infiltrate the basement, leading to moisture problems and potential damage. Properly addressing these causes often involves implementing effective waterproofing measures, repairing foundation cracks, improving drainage systems, fixing plumbing issues, sealing openings, and managing humidity levels in the basement.

 

Can I install a sump pump as part of my basement waterproofing system?

Yes, installing a sump pump is a common component of basement waterproofing systems. The sump pump is typically equipped with a float switch that activates the pump when the water level in the sump pit reaches a certain point. By incorporating a sump pump into your basement waterproofing system, you can enhance its effectiveness in preventing water damage and maintaining a dry basement environment.

Will basement waterproofing fix foundation settlement or structural issues?

Basement waterproofing typically focuses on addressing issues related to water intrusion and moisture management rather than directly fixing foundation settlement or structural issues. While some waterproofing measures, such as sealing cracks in the foundation walls, can help mitigate water infiltration resulting from settlement cracks, they do not fix the underlying structural problem.

Foundation settlement and structural issues require separate assessment and repair by a qualified foundation contractor or structural engineer. These professionals can evaluate the extent of the settlement or structural damage and recommend appropriate repair methods, which may involve techniques like foundation underpinning, helical piers, or wall stabilization systems. It’s essential to address foundation settlement or structural issues properly to ensure the long-term stability and integrity of the building.

What services do you offer for basement waterproofing?

We provide a range of services, including interior and exterior waterproofing, foundation crack repairs, sump pump installations, basement drainage systems, and basement sealing solutions.

Can basement waterproofing prevent water damage during heavy rainfall?

Yes, basement waterproofing is designed to prevent water damage during heavy rainfall. It helps divert water away from your foundation, keeping your basement dry and protected.

How much does basement waterproofing cost?

The cost of basement waterproofing can vary widely depending on several factors, such as the extent of the water damage, the size of the basement, the location, and the chosen waterproofing method.

Interior waterproofing methods, such as sealants and drainage systems, are typically less expensive than exterior solutions.

Exterior waterproofing methods, which involve excavating the soil around the foundation and applying waterproof membranes, can be more costly.

Call us now to assess your specific situation and provide accurate cost estimates.

How can I ensure proper drainage around my foundation to prevent water issues?

To ensure proper drainage around your foundation and prevent water issues, consider the following measures:

  1. Grade the landscape away from the foundation.
  2. Install downspout extensions to divert water away from the foundation.
  3. Clean and maintain gutters for proper water flow.
  4. Consider installing French drains for excess water management.
  5. Apply a waterproofing membrane to the foundation walls.
  6. Avoid planting large-rooted vegetation near the foundation.
  7. Install window well covers.
  8. Regularly inspect for signs of water intrusion and address issues promptly.

If you have any questions or concerns about finding the most suitable drainage solutions for your specific situation, please don’t hesitate to reach out. Our team of professional landscapers, drainage contractors, and foundation specialists is here to provide expert guidance and tailored recommendations to address your property’s unique needs.

Is it possible to waterproof an existing finished basement?

Yes, it is possible to waterproof an existing finished basement. While it can be more challenging compared to waterproofing an unfinished basement, there are methods and techniques that can be employed to mitigate water issues and protect a finished basement from moisture damage.

What should I do if I notice water seepage or leaks in my basement after waterproofing?

If you notice water seepage or leaks in your basement after waterproofing, it is crucial to promptly address the issue.

Check for any maintenance issues with your gutters, downspouts, and drainage systems, ensuring they are clear of debris and functioning properly. Taking swift action will help identify and resolve the source of the water seepage, preventing further damage to your basement.

 

Will basement waterproofing eliminate musty odors in my basement?

Basement waterproofing can help reduce or eliminate musty odors in your basement, but it may not be the sole solution. Musty odors are often caused by excessive moisture or the presence of mold and mildew, which can result from water infiltration or high humidity levels. While waterproofing measures can help prevent water seepage and reduce moisture, additional steps may be necessary to address existing musty odors. These may include improving ventilation, using dehumidifiers, removing any existing mold or mildew, and ensuring proper drainage and airflow in the basement. If musty odors persist after waterproofing, it may be beneficial to consult with professionals experienced in mold remediation and indoor air quality to identify and address the underlying causes.

Are there any environmentally friendly options for basement waterproofing?

There are several environmentally friendly options available for basement waterproofing. These include exterior excavation and drainage systems that redirect water away from the foundation, interior water management systems that capture and remove water that enters the basement, exterior waterproof coatings formulated with eco-friendly materials, French drains that collect and redirect water, and sustainable landscaping techniques that promote natural drainage. By opting for these eco-conscious methods, homeowners can effectively waterproof their basements while minimizing the use of harmful chemicals and reducing their environmental impact. Consulting with a professional basement waterproofing contractor will help determine the most suitable and environmentally friendly solution for individual needs.

What steps should I take if I discover water in my basement?

What steps should I take if I discover water in my basement?

Are there any long-term benefits of basement waterproofing besides water protection?

Yes, basement waterproofing offers several long-term benefits beyond water protection. These include preventing structural damage to your home’s foundation, reducing the risk of mold and mildew growth, improving indoor air quality, and increasing the overall value of your property.

Annette Casatelli

I received a few quotes to get the walls in my home filled in with blown in insulation. Zavza Seal was affordable and they did an excellent job.

They were very concerned with cleaning up, which I appreciated. I felt the difference in my home immediately. No more freezing cold walls. I recommend them, hands down.

Five Stars Reviews 3

Ellen Szuchmacher

Efficient, courteous and responsible workers. The job was quoted as being completed in 2 days but more work was required and they returned on the 3rd day and completed the job without additional charges. They reinsulated my crawlspace (not an easy job). I recommend Zavza Seal without reservation.

Michael Rutigliano

Couldn’t be more satisfied with the job Zavza Seal did. Brendan and Jake were accommodating, fair and extremely knowledgeable. Their team worked incredibly hard that day under difficult conditions and did a great job. I manage a multi-unit HOA and we will definitely be using them again.
