Basement Waterproofing

  • No.  These are two separate issues and need to be addressed with different solutions.

  • What we hear from homeowners is that they want a long-term warranty and peace of mind the issues will not happen again. That is why the best solution is an interior drainage system.

  • No. However, that is why it is best to consult with a waterproofing professional so that they can design the best solution for you based on the issues you are facing in your home.

  • Yes. Again it is important to work with a professional so that you get a solution with a long-term warranty and a company that gives you the peace of mind that they will do the work right and stand behind it.

  • There is no one size fits all approach. The solution to waterproof your basement needs to be designed specifically to address your issues and to accomplish your goals.

Basement Waterproofing & Drainage

  • Basement condensation occurs when arm, moist air comes in contact with your cool basement walls and floor.  Since the basement is below grade, it is cooler than the outside air temperature in the warmer months of the year. Warm outside air is drawn into the basement like a vacuum and when it comes into contact with the cool, basement air, that is when condensation occurs.

  • Yes, you can take it with you.  It is also very light weight

  • Efflorescence- it is a mineral deposit left behind after water or moisture was present

  • New construction waterproofing is often completed with no or a minimal warranty.  There are different ways in which it can be waterproofed but the most common way is through a spray on sealant on the walls which can be damaged when the soil is backfilled around the house and/or can crack when the house moves or shifts.  Also, exterior drain tile is commonly installed.  Since the tile is sitting in the dirt, it can often become silted closed or damaged during the backfill process.

  • Thrasher/Midwest provides solutions with long-term warranties.  Considerations include the type of waterproofing system you install and the type of sump system you install.  There are different options that offer different levels of protection.

  • If you think your basement is going to flood, you should remove any finished materials that you believe the water will come in contact with.  Also, make sure nothing is on the floor.

Interior Waterproofing Systems

  • This takes a professional to come in and do an inspection to determine an issue.  Most wet basements are caused by exterior issues.

  • Depending on the severity of the problem, there a few systems available to solve a  leaking basement.  Sump pump systems, hydraway systems or edge drains are all systems used to fix water in a basement.

  • Yes. You can even use a sealant but often the moisture is still coming in through the concrete walls and floors which will eventually break the seal of the sealant material and water will get through again.  It is better to fix the problem by install drainage system.

  • There are lots of different types.  The main thing is where they are installed.  If installed next to or below the footing, the drainage system is in the dirt/mud and are more susceptible to clogging.  If installed on top of the footing, the system is out of the dirt and mud and will not clog.

  • It depends on the what is causing the leak in your basement, there are both interior and exterior solutions. Basement drain systems will help prevent flooding and mold while basement wall options allow you to further protect your space.

  • Yes.  It depends on the company and product what the warranty is.  At the end of the day the warranty is only as good as the company that stands behind it.

  • We don't use a "brush on" water sealer to stop water intrusion. Our system of waterproofing includes installation of a WaterGuard® interior drainage system and a TripleSafe Sump Pump system. If you want to restrict moisture and water vapors from entering your basement and add a layer of basement sealer to protect from mold at the same time, we install our CleanSpace® Basement Wall Vapor Barrier.

  • Cracks form in foundation walls for three main reasons; shrinkage cracks from curing concrete, cracks from foundation settlement and cracks caused by expansive soils. Foundation wall cracks vary in severity from a simple cosmetic issue to a major structural problem with your home. However, even serious foundation problems, when addressed early on, can be quickly and permanently fixed.

  • Exterior systems sound just like what they are - systems placed on the outside of your home in the hopes of diverting groundwater, rain and snowmelt away from your foundation. While great in theory, exterior systems definitely have their flaws. The most obvious problem with these types of solutions is that they require the outside of your home's foundation to be accessible. This means bringing in heavy equipment to excavate space all around the affected area so that crews can access your foundation.

  • Yes, there are interior solutions. A drainage and sump pump system placed on the inside of your home to channel water up and out before it has a chance to accumulate. Sometimes called a French drain, these systems are installed below your basement's concrete slab floor around the perimeter of the home. These drains rest against the inside of the foundation wall, collect any water that seeps in, and direct it to a sump pump pit where the water is then pumped up, out and away from your home.

Some of the most common sources of basement water damage include leaky basement walls, basement drains, foundation wall cracks, leaky egress windows, and faulty or damaged basement sump pumps.

Wet Basement Repair

Mold growth can seriously damage your basement walls, your possessions, and even your indoor air quality. Not to mention, a home with a wet basement becomes much more difficult to sell. In fact, a wet basement is one of the most serious "red flags" that deters buyers and lowers your home's value.

  • More than likely, it's a sign of mold. Mold can grow anywhere where there's air, moisture and organic material to feed. It's particularly likely to flourish in damp, humid areas of the home. It's no surprise that basement mold is a common problem for homeowners.

Our patented system that includes a non-clogging WaterGuard® interior drainage system, our TripleSafe Sump Pump System plus, a layer of basement sealer to protect from mold at the same time with our CleanSpace® Basement Wall Vapor Barrier will eliminate the worry of a wet basement.
