"My certified inspector MatthewCote out of the Belgrade, MT office found i have a natural spring comming up in my crawlspace. I knew I had water streaming all over crawlspace and my husband believed it was due to watering lawn of the hill our house sits on. Matt was great to work with, he was totally professional. He explained my situation and showed me in photos and map of my basement what this ssprincause, how it had eroded and damage caused. It has been going on for quite a few years, of which I noticed escalation of water even though I decreased watering on above lawn. I wish I had researched this sooner. But MATT assured me it's not too late. He was clear and concise as to what I needed done to resolve and eliminate further damage by installing 2 sump pumps, installing trenches & piping to drain all areas of water, draining ouside of house past septic and leach field, add a humidifier and encapsulation of crawlspace. I highly recommend Groundworks and Matt to anyone."

"Several times we asked Peter if he had a Superman outfit hidden under his work attire. For every problem we encountered during the bathroom remodel, Peter had a solution. Every time we asked "Can we do this?" he answered "We can do whatever you want." He was so easy-going and always in a good mood. He turned a dated bathroom into a 5-star hotel experience. Peter did such a good job for us that we are planning to use his services again for a new deck. Thanks to Peter and his amazing wife/manager Piper!"

Basement Waterproofing FAQs, answered by experts

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

“Basement waterproofing” sometimes refers to applying a waterproof sealant to basement walls, in which case you would use a waterproof paint, often made of latex. However, there are many methods you can use to waterproof a basement, including exterior drainage systems, interior drainage systems, dehumidifiers, and more. As such, the materials you use can vary depending on the methods you use.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.
