Finding the Right Solution

Basement waterproofing is no easy task to handle. However, finding a viable solution might help you save both time and extra costs in the long run if you’re dealing with basement walls that leak or water rising through the floor.

It is not advisable to store belongings or live in a damp basement because it smells terrible and is likely to develop mold issues. There are several causes of water seepage, leaks, flooding, and moisture in basements; some are simple to remedy, while others call for assistance from a specialist in waterproofing basement. Mold growth, foundation problems, and low indoor air quality can all be avoided using a reliable basement waterproofing solution.

There is nothing as a one-size-fits-all method for waterproofing a basement. The source of the issue, your home’s location, and the kind of foundation you have will all affect your house’s best course of action.

Advantages of Basements Waterproofing

There are many advantages of a clean and dry waterproof basement. A few of these are:

  • Prevention of Propertys Structural Damage
  • Reduced energy bills and consumption
  • No possibility of odd or unpleasant scents in the basement
  • Protection of your and your family’s health. Mold removal is arguably the biggest benefit of getting your basement waterproofed.
  • Water conservation

Types of Basement Waterproofing

Here are some details on the most popular interior and exterior waterproofing basement techniques to aid your choice.

Applying Sealants & Epoxy Injections

Although sealants and epoxy injections are sometimes viewed as temporary repairs, some homeowners choose a basement waterproof sealant when installing a drainage system that is out of their price range. These masonry waterproofing materials are applied to stop moisture from seeping through basement walls.

Applying sealants over painted walls or efflorescence is not recommended (white mineral deposits accumulate on the surface of concrete walls). In addition, when the foundation walls expand and contract, the substance in many epoxy injections might break, which is a common issue.

To prevent flooding, it’s crucial to establish a drainage system in addition to patching up leaking wall fractures. Thus, applying sealants and epoxy injections are well worth it. The same is true for crawl space waterproofing.


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.

Get the right solution

Some homeowners choose a short-term solution depending on the severity of the issue. Still, they frequently need to install a drainage system to effectively solve their basement water problem. Because outdoor waterproofing requires more workforce, heavy equipment, and time to accomplish than interior waterproofing, it often costs substantially more.

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.

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.

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.
