"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

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

Periodic inspections and addressing drainage issues prevent further damage.
