"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.

A few other tips include performing regular foundation checks, cleaning spouts and gutters, and installing exterior drains if needed. For those living in a hot and arid area, you should water your foundation every other day.

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.

Crawl spaces are the more desirable option overall because they provide additional space for storage and utilities, but they are more expensive to install and maintain. Slab foundations are considered a better option in warmer climates where the depth of the frost line isn’t an issue because they’re more affordable, but crawl spaces are better in areas where the frost line is deep or where flooding can be an issue.

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.

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