"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."

Foundation Drain Installation FAQs, answered by experts

Gravity can make it difficult to make plumbing work in a garage if your plumbing is lower than your drainage point. Fortunately, there are ways to create drainage when adding a bathroom to a sunken garage. Plumbers will recommend using an upflush system that discharges into a pump from the back of the toilet.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

No, you can’t drain your sump pump into your home’s sewer system. In fact, it’s against the law in many places because dumping extra water into a municipal water system can disrupt or overwhelm the treatment process. And for similar reasons, you shouldn’t discharge a sump pump into your septic system, either.

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.

Whether professional drainage installation is covered by insurance depends on your specific policy and the circumstances. In some cases, homeowners insurance may cover the cost if drainage problems pose a risk to your home's foundation or structural integrity. However, it's essential to review your insurance policy, understand the terms and conditions, and consult with your insurance provider to determine if your particular situation qualifies for coverage. Coverage may vary, so it's crucial to clarify the details with your insurer.
