"we had concrete pads added after home construction. One pad had a 2 inch settlement on one corner. Complicating this was a stone wall sitting atop the pad. Excellent restoration was done by Groundworks From Bozeman. After a thorough evaluation by Ben, Chelsea and Tyler were prompt, educational and successful. I Highly recommend this company for your concrete/foundation needs."

"They came to my residence and provided a cost and time estimate in a friendly neighborly manner. They stayed in touch to confirm our scheduled work date and time. They were punctual and thorough in explaining how the work would be done and listened when I commented on the locations of sprinklers and best approaches as to keep our lawn from unsightly track marks. The work was completed professionally as per our agreement. I would highly recommend them, and will use them for future landscaping work."

Basement Waterproofing questions, answered by experts

To maintain an outdoor structure, perform regular inspections for damage, leaks, and weak joints. Clean the structure regularly, treat or repaint wood surfaces for weather resistance, and reinforce any weak joints to prevent deterioration and ensure its longevity.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

Yes, many repair services include reapplying waterproofing and UV-resistant coatings.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.
