"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"Out of the three basement waterproofing experts we called to offer solutions after getting a lot of water in the basement of our 1925 home, Joe at The Real Seal was the only one who seemed to take serious time in investigating the cause. He even came back a second time after we got more water in another spot to see what could be causing it and what a cost-effective solution might be. On top of that, the price was right! We never ever felt pressured into committing to the work, and they seemed confident in their skills to get the job done. Our partial interior drain tile job was finished in two days. While we can't yet vouch for the drain tile's efficacy since we haven't gotten a large spring rain yet and we're still in the process of refinishing our basement after it was demoed for this work, we expect we'll have a dry basement!"

"I worked with Austin Werner at Real Seal to get some basement sump pump work done. He came out initially and gave me a quote and different options for my basement sump pump. He was very knowledgeable and gave pros and cons of different options. The quote was priced very fairly. They were able to get us on the schedule quickly. On the day off, the Real Seal technician called me the morning to let me know what time they would be here. The job was done very professionally and they answered all my questions. They cleaned up after the install. Highly recommended."

"I needed the sill plate and rim joist replaced, sister in the joist in the front of our house. They had many jobs going on so they brought in a crew Anthony, Jerry and Jose from New Jersey so the could get mine done. Anthony let me know what they were doing as things progressed. He asked me if I had questions as he worked. Everyone in the crew where so considerate. The laid down tarps to walk on so as not to damage my floors and they cleaned up everything and the end of the day. I would recommend Chicago Basement Solutions to anyone who needs work done in their crawl of basement."

Basement Waterproofing questions, answered by experts

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

Encapsulation can take the place of crawl space vents since it protects the area from moisture and air all year round. Determining whether you should open or close crawl space vents can be complicated since it often depends on the weather and humidity. Skip this step by investing in crawl space encapsulation whenever possible.

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.
