"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."

"Jeff and his crew waterproofed our basement last February after we dealt with water leakage issues for three years. They did a tremendous job for us and finished the job in a timely manner and on budget. As proof of the quality of their workmanship, our basement was bone dry after the 5.5 inches of rain that fell on Metamora/Germantown Hills, and the greater Peoria area on July 15. Thanks to Pivotal, I'm not bailing out my basement this morning. Thanks again Pivotal--you're the best in the business, and we are so happy our neighbor recommended you to us."

"They are great to work with. Communication was superior. They stand by their work. A few years ago I had waterproofing done in my basement and this time they spray foamed the cavities of the basement too. Both times they did awesome work and cleaned up too! I highly recommend this company!"

"Joe and his crew have done a tremendous job over the last 10 months helping me get my home ready so I can put it on the market this summer. From the beautiful bath remodel to painting ceilings, walls, re-caulking my basement walls and power washing my roof and deck, they've always gone over and above what I've expected. My messages are promptly returned and Joe dispatches his crew out to my house in a timely manner. Thanks for running over to "fix" a problem that turned out not to be a problem at all! Thanks again to you and your capable crew at Kitchen and Bath Specialties!! Joan"

"My husband and I began notcing cracks in our basement walls within the last few months so we contacted Frank to diagnose the problem. He was very knowledgeable and promptly told us what needed to be fixed. His crew began work within a week of us meeting, they worked quickly and efficiently and the job was done in 4 days. They knocked out 30 feet of our basement wall that had been damaged and the work was done in an extremely clean manner. They left the area meticulously clean. We also had 38 feet of wall on the other side of our house piered because it was settling. Frank lifted the house and piered the wall with a jacking system. We were extremely surprised as to how quickly all of the work was done and appreciated the professional manner in which it was completed. Frank even provided us a lifetime tansferable warranty. We highly recommend using Frank for any foundation repair work.

Basement Waterproofing questions, answered by experts

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

Below-ground shelters are the best in terms of durability, but there is a risk of flooding and obstruction. Modern technology and rigorous construction requirements make above-ground shelters a better option for accessibility, safety, and, usually, your budget. They may not have the same aesthetic appeal, but many of their features make above-ground shelters a better option. 

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

You don’t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It’s ideal for homes in humid areas.

In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.
