"I want to recognize three young men who recently completed our basement work through Groundworks: Matt, Taylore, & Gavin. The work was thorough, clearly explained, & the finished product looks excellent. But the biggest positive was the crew. They worked incredibly hard every day on a physically demanding, messy job, yet remained professional, disciplined, & respectful. They took great care of our home, kept debris contained, & cleaned up afterward. Matt took time to explain the full system to us & went above & beyond to help replace insulation that had fallen, even though it wasn't part of the job. Taylore & Gavin were equally helpful, helping us salvage & store shelving materials and remove a few stubborn pieces we couldn't manage ourselves. I'm genuinely impressed by their work ethic, attitude, & pride in doing the job right. I would absolutely recommend Groundworks, but especially these three young men. They represented the company exceptionally well!"

Basement Waterproofing questions, answered by experts

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

The purpose of soffits is to circulate air, so a blocked soffit means the air in your attic becomes stagnant. This can lead to a number of problems, mostly moisture-related, that can cause damage to your health and your home. The good news is that unclogging soffits is relatively straightforward, and if your attic is easy to access, an easy DIY project.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

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.

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
