Let�s make your basement or Crawl space dry, We have been servicing Illinois since 1979 and pride ourselves on the quality of work that we provide to our homeowners.

"My basement has always leaked and was never dry. I called Donnie Felton, who was highly recommended by a few friends, he was very knowledgeable and explained exactly what he would do step by step. He showed up the following week and completed the job in two days. My basement is now dry and does not see a drop of water even during the heaviest rain. I love not seeing any water in my basement. I would highly recommend Donnie Felton."

Pivotal Basement Solutions, LLC is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty, and responsibility in all of our jobs. We are a locally owned and operated business serving Peoria, Bloomington, and surrounding areas.

"I own a house which is around 90 years old. Its basement had compromised walls, one of which was seriously bowed. In addition, after heavy rain, the basement floor would be wet. I got estimates from three companies to correct these problems. Pivotal was a clear standout. The owner Jeff, his family members Andy and James, along with the rest of the crew make up a terrific team. Jeff and Andy visited my basement twice for long and detailed planning sessions. The actual work took 7 days for completion with James as foreman. All the problems of my basement were fully addressed. My bowed wall is now vertical, with strong supports along all walls every few feet. A complete waterproofing system was installed which feeds to my sump pump. Cleanup after completion of the work was very thorough. Bottom line: Pivotal is a totally trustworthy top quality company!! "

Basement Waterproofing questions, answered by experts

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

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.
