Repairing Leaking Foundation Wall Cracks & Penetrations
Proven Solutions For Foundation Wall Crack Issues
Permanently Sealing A Wall Crack
Concrete expands and contracts naturally as moisture and temperature conditions fluctuate.
To properly repair a wall crack, a flexible, expandable material must be used to seal the opening.
Water will enter a basement anywhere it can, starting with the path of least resistance. If there is an unsealed opening in your basement wall, this will often be the route that water uses.
Often, this opening in the wall is in the form of a crack -- either in the concrete or the mortar joints. It is also common for water to seep in around a pipe, cord, or wire that penetrates your foundation wall.
This can create a significant flooding nuisance -- one that's creates a particular nuisance if the homeowner is planning to finish the basement. The cracks must be reliably and permanently sealed before walls and insulation is installed.
Fortunately, provided that this is not a structural crack, we have a simple, common-sense solution for sealing these openings. Our crack repairs include a written warranty that can be transferred to the next owner of the home, should you decide to sell.
If you do have a structural issue, we recommend that you contact Foundation Supportworks, Inc. -- our sister network. They serve throughout Canada and the United States, specializing in structural issues of all kinds.

How To Repair Leaking Wall Cracks & Penetrations
At Basement Systems, our solution to leaking wall cracks and penetrations is our FlexiSpan™ Wall Crack Repair System -- a patented, award-winning system available exclusively from Basement Systems Dealers.
The FlexiSpan System is installed in three simple steps:
Injection Of A Polyurethane Sealant
Our first step in sealing your wall crack will be to inject the crack with a sealant.
The material used to seal your walls should be flexible, and able to stretch out to many times its size without breaking or coming loose. This requirement eliminates many common sealing materials, including caulk, waterproof paints, and hydraulic cements. In the case of hydraulic cements, even when they do hold, the rigidity of the cement patch can lead to a new crack can form farther down the wall!
Additionally, many products work poorly when injected into a wall crack. Mortars may seep through the other side of the crack, while caulk will need to be applied to a clean surface to work properly. In most cases, a basement wall crack leaking with groundwater is not clean!
We have developed a unique polyurethane sealant that can flex to many times its size, will not seep through the far end of a crack, and can be applied in basement cracks that are not clean. This powerful sealant is durable enough to hold strong, even as the walls flex and shrink naturally due to temperature and moisture conditions.
Create A Secondary Drainage Strategy
No crack sealing solution is perfect. Therefore, as with other waterproofing systems, the best systems are designed with quality products, and also include at least one level of redundancy to serve as a backup.
The FlexiSpan Wall Crack System's polyurethane sealant is backed by a foam strip that's laid over the top. This foam strip is designed to collect any water that finds a way past the seal, directing it downwards to the perimeter drain of your waterproofing system. If a perimeter drain is not present, we will construct a small dry well (about 5-10 gallons in size) below the floor before sealing the wall crack.
In most cases, this foam strip backup is not needed at all. But if you're finishing your basement, using it to store valuables, or selling the home, it's great to know that you have a reliable, multilayered system solving the problem.
Complete The Job & Add Finishing Touches
We pride ourselves on leaving all our jobs looking clean, neat, and professional. Once the polyurethane sealant has been injected into the wall crack, and the foam strip is in place, we will coat the entire repair with a polyurethane sealant and tool it off to look neat and clean.
If a drywell was constructed beneath the floor, we will restore your basement floor with fresh concrete. Any debris created during the installation, is cleaned up and removed by your installer.
At the end of the installation, you will receive a warranty, in writing, for your foundation crack repair. Now you can rest easy, knowing that your problem is solved and your basement is protected from leaking issues.
