Inspected and Correctedtm
A DRY Basement, No Matter What The Problem!

So why use Basement Flood Protector for corrective basement waterproofing? 3 main reasons:
1. Expertise. We have been in this business for decades and have inspected, corrected, and protected over 25,000 Chicagoland families' basements. We are NOT the biggest, but our reputation proves that we are the BEST. Our crew members have been with us for many years so you aren't getting workers from some big company with no training and experience.
2. Quality and Technology. After thousands of DrainShield installations (Interior Drain Tile) we have NEVER had to provide a warranty correction! That means a LOT when it comes time to putting the basement back together!
3. Price and Warranty. We are not in business to be the cheapest or expensive. We simply price the job at a fair price that reflects the market and also hand you the BEST warranty in the business.

A dry basement is within reach! Don't let water intrusion steal valuable living and storage space from your family. We can inspect and correct any basement seepage/flooding problem and make a repair recommendation that will last a lifetime. The four most common issues covered on this page are: Foundation Leaks, Seepage, Sump Pits, Exterior Foundation Membranes. Also, you can download our Water Damage Spec Sheet for more detailed infomation on potential water damage problems.

Foundation Leaks:

Poured concrete foundations often crack simply because of settling. If the crack grows or the foundation wall is deflected, the advice of a structural engineer may be required. However, most cracks are completely harmless to the integrity of your home and might not even leak. We suggest our injection method on any crack that leaks or will be inaccessible in the future because of basement finishing, etc.

We use an injection method to repair leaking cracks in poured foundations because it is the most permanent and time-tested repair available. Injection ensures that the crack is completely filled from the inside out. Other companies use materials that merely cover the surface of the inside or outside of the crack (note: injection from the outside is rarely possible). Or they may simply install materials to allow the crack to continue to leak, but to do so under the floor or into a baseboard channel.

We select from several proven injection materials depending on the crack. Epoxy resin will provide more rigidity, but may be susceptible to re-cracking. We use urethane more commonly, since it will seal permanently, but also provide elasticity in the event the foundation may experience slight seasonal movement. Performing crack injections properly is a difficult process and takes years of expertise, so be suspicious of any companies that criticize this valuable skill.

Here is a typical repair by a competitor. This crack caused thousands of dollars of damage to a finished basement. The crack was repaired on the surface, but not injected:

Only Basement Flood Protector pressure injects the crack and then hands you a lifetime, transferable warranty:

Spec Sheet


Excessive hydrostatic pressure in the soil surrounding your basement walls and floor can lead to seepage problems. Typically, this seepage will enter the basement through floor cracks and where the floor and wall meet. Often, failed outside drain tile (or a home built without drain tile) water pressure will build up under your floor causing water seepage up through the floor. Installing an interior drain tile system will solve this problem for a lifetime. Beware of other contractors that push shallow channel, or "trak", systems that only drain water just under the floor level, and cost nearly as much. Real drain tile with real perforated pipe, real washed stone, in a real 8-12" deep trench, covered over by real concrete is the best way to solve hydrostatic pressure. Don't take our word for it... ask any reputable engineer or architect. It only costs a bit more to do it right, even though it's way more work (for us... hmmm, makes you wonder why the other guys charge so much for the shallow, easy version). There are no short cuts when it comes to drain tile, the best way IS the hard way.

The first picture shows an installed interior drain tile immediately before final stone backfill and concrete. Note the drain tile is placed alongside the foundation footing. The competitors' trak systems cannot achieve this proper level of drainage. The second picture is what the DrainShield job typically looks like when finished. The third picture is an excellent cutaway of what has been installed:

If you have a radon remediation system in your basement, installing the DrainShield interior drain tile system can often improve your radon system's effectiveness (check with licensed radon remediation contractor for verification). We can usually install the DrainShield interior drain tile after the radon system is installed or with cooperation from the system's installer. Our genuine DrainShield installation provides you with a lifetime warranty against pressure related seepage in your basement!

We are often asked if we can do the drain tile from the outside. We can, but strongly discourage you from doing this since yards, landscaping, sidewalks, etc. can be destroyed as seen below in the pictures of jobs we have done:

Sump Pits:

A sump pit is a fundamental part of basement flood protection. The sump collects water from the drain tile and houses the sump pump(s). Over the years we have installed and replaced thousands of sump pits. Once the pit is installed, you will need an electric sump pump to serve as your primary protection and a battery backup sump pump to to serve as a backup to protect against power failure or primary pump failure.

NEW!!! The better sump pit is finally here! Introducing The Protector "Big Bottom Basin" . A two chamber, extra wide bottomed, clear cover sump pit, this pit will extend the life of your pump equipment because of it's larger storage capacity, reducing the frequency of pump cycling. In addition, The Protector Pit will allow more room for pump equipment to fit comfortably and operate freely, without risk of common tight space issues.

Exterior foundation membranes:

Leaks through block, brick, or stone foundations that cannot be repaired by epoxy injection, as described above, can often be repaired by a rubber membrane. A rubber membrane can be adhered to the exterior of the foundation, providing a waterproof barrier. Of course, excavation of the foundation and significant prep work is typically required.

These pictures demonstrate a membrane application.

What if I have a finished basement?

Our services can still be done in a finished basement. It usually does, however, require more prep work. For interior drain tile drywall or paneling on walls must be removed at least a foot or two up from the floor. Then, the studs must be cut in order to accommodate the cove plate system of the interior drain tile (if cove plate is not being installed, removing the studs is not necessary). We will work with you to accommodate your specific needs. We work with homeowners everyday to accommodate finished basements.

Occasionally, a drain tile can be installed without doing this described prep work. The inferior shallow channel/trak systems (see above) don't always require this prep or it's possible that the way the finished walls are built will allow for us to install the drain tile and cove plate strip without much removal.

These pictures show some of the steps to prep for an interior drain tile:

Do you structurally repair or correct settled foundations?

We do not perform structural repair or correct settled foundations, but we highly recommend our friends at Dave Pate & Son's, Ltd. for such problems. You can visit them at
