"Groundworksâ listened to our input and throughly evaluated the requirements to support the basement walls and prevent water from coming in. They were on time and communicated clearly and timely. The Foreman did an evaluation and recommended a couple changes to the plan that I agreed with and weâ re beneficial. The 3 workers knew what they were doing and worked hard. I appreciate the manner they communicated and they were very friendly. Overall, they did a great job!"

Concrete performance depends on planning, from subgrade prep to finish and cure. An excavating company in Glenwood , will compact the base, set forms, and confirm reinforcement placement before the first truck arrives. In cooler mornings typical of Glenwood, IA, crews may adjust mix timing and finishing sequence to avoid surface tearing. Control joints are laid out to manage cracking, and edges are tiled where traffic or freeze-thaw cycles are common. Pro Site Company coordinates with excavation and grading teams to align pads, sidewalks, and approaches with site elevations and shed water. Where runoff is a concern, drains or drainage tubes are set before the pour, and slopes are checked with levels to maintain flow. For farm or outbuilding slabs in Mills County, we may recommend thicker edges, fiber reinforcement, or a vapor barrier based on intended loads.

Basement Waterproofing FAQs, answered by experts

Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.

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.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.
