Proven Foundation, Crawl Space, and Basement Repairs in Sioux City
Groundworks, foundation solutions crafted with pride
Schedule Free Inspection
Situated near the northwestern part of Iowa, Sioux City is located in both Woodbury and Plymouth counties, with the majority of the city being in Woodbury County. “Siouxland” refers to Sioux City and the surrounding areas of northwestern Iowa, northeastern Nebraska, and southeastern South Dakota and is a term of endearment amongst local residents.
Situated at the furthest upstream point of the Missouri River, Sioux City is both a travel destination as well as a peaceful area to live. With an average annual rainfall of nearly 26 inches, it is slightly below the national average. However, it’s the fact that more than 60 percent of that rain falls during the summer months when humidity levels often reach 90 percent, that’s the problem. Add in the annual 30 plus inches of snow, and it’s no wonder Sioux City homeowners deal with wet basements and crawl spaces nearly year-round.
The area’s soil differs depending on where you live in Woodbury or Plymouth County. Most soil is silt loam-based with varying levels of clay. The soil across the region also has different degrees of drainage, ranging from well-drained to poorly-drained. To sum it up, homeowners in Sioux City can experience several different types of foundation problems because the soil conditions differ considerably from area to area.

I purchased a home in need of repairs. I looked around at different options to have a basement wall secured. I decided to go with Groundworks because the pricing was fair compared to other companies. Three men arrived, they worked very hard in the blistering cold to make sure the job was done correctly and professionally. Adriel explained in detail about the work being performed. They were on time when they said they would arrive, took great care of the house and did a fantastic job. After my experience with Adriel, I will recommend this company to friends and family. Thank you!!

Nick Waldron and Mike Wrenn both helped to plan and install an expansion joint in my driveway. Service was exceptional. Nick was very detailed in his explanation and helped me understand the value of the expansion joint installation. Mike arrived on time and got straight to work. He was very professional and efficient. I was very happy with the whole process. Very professional and will recommend.

We highly recommend Groundworks. Paul Winder was so professional and knowledgeable about what we needed to do to fix the foundation of our home. There were no pushy sales pitches and Paul was very honest and straight forward about what we needed and didn’t need. With the financing they have to offer it’s very affordable and we now have a peace of mind that our home will be solid for many years to come. Thank you Groundworks and Paul Winder.

I had such a great experience with CLS. Dave, the owner personally came out to the house to give me a quote. I really like that the owner prefers to meet each client to fully understand the situation. The crew came out and was respectful and clean. They did a great job and the price was better than the other quotes I received. I highly recommend CLS.

Sioux City Foundation Repair
The many soil types across the region mean Sioux City homeowners can experience foundation problems for several reasons. Foundation and drywall cracks, bowing basement walls, and settling homes are all common problem signs.
When the soil beneath your house fails to support the weight of your home, it sinks and settles until it finds resistance. You’ll not only notice uneven floors but also stair-step cracks, sticking doors and windows, and drywall nail pops. Groundworks has been repairing sinking, settling foundations for more than 30 years. It remains one of the more complex foundation repairs, so it’s important to choose a company with a proven track record to ensure you’re getting a permanent solution the first time.
Our pier systems permanently stabilize your sinking foundation by using metal piers driven deep into stable soil. Your Groundworks inspector will determine the correct pier for your home. Once installed the weight of your home is transferred from the failing soil to the piers and lift is attempted. When the lift is accomplished, foundation cracks and gaps above doors and windows repair themselves.
Common Foundation Problems
Basement Waterproofing in Sioux City
Given the large amount of precipitation Sioux City sees year-round, both in the way of rain and snow, it’s no wonder so many homeowners struggle with a wet, leaking, moldy basement. All the water and snow saturate the soil surrounding your home and eventually finds its way inside through cracks or vulnerable points like where the wall and the floor meet.
Once water finds a way in, the problem won’t stop until corrective measures are taken. Mold, humidity, and mildew all cause long-term issues for homeowners. Mold weakens wood, and the spores cause health problems for your family, especially those with allergies and asthma.
Groundworks has a full lineup of water management products, from interior drains that are installed at the basement perimeter, to sump pumps that collect the water and pump it out of and away from the home, to an energy-efficient, self-draining dehumidifier. Your basement may or may not need all these products, but a free foundation inspection will give you a better picture of what needs to be done to keep your basement dry and healthy.

Sioux City Crawl Space Encapsulation
Sioux City has a mix of new and older homes. Unfortunately, both have issues with crawl space moisture and mold, but typically only older homes have crawl space vents. Old building science thought humid air would flow in and flow out, causing no harm to the crawl space or your home’s structural integrity. This was proven to be incorrect, although homes are no longer built with crawl space vents, plenty still remain in older homes.
Vents allow humid outside air into the crawl space where it becomes trapped and unable to exit. When the air of a different temperature mixes with the original air, condensation happens. This leads to mold, mildew, wood rot, and an overall unpleasant living environment.
We know that half the air we breathe comes from the crawl space, so you’re breathing mold and mildew spores, pest droppings, and humid, musty air if your crawl space is untreated. Groundworks offers several options to seal your crawl space from the outside environment and create dry, usable space.
Where crawl space flooding or moisture issues are prevalent, crawl space drainage can help direct water to a specially designed sump pump. From there it will be pumped out of the crawl space and away from your home. To seal moisture from the rest of your home, a high-quality 20-mil vapor barrier is installed on the walls and floor, locking out moisture and creating a dry, clean space.
Concrete Lifting in Sioux City
If the concrete surrounding your Sioux City home is spongy or sounds hollow when you walk on it, there is most likely a settlement problem. Concrete slabs rely on the soil beneath them to stay level. If the soil erodes or washes out, nothing is left to support the weight of the slab. Eventually, the slabs sink, commonly cracking while doing so. Uneven slabs create tripping hazards and are especially scary around a pool deck or stairs, plus they look unsightly.
Support needs to be given back to the slabs with a material that won’t wash out again. Groundworks’ SettleStop PolyRenewal™ uses waterproof polyurethane foam to fill voids and gently lift the slab. This support can be relied on permanently because of its waterproof material, it won’t wash out.
Small holes, the size of pennies, are drilled into the slab, and polyurethane is injected using a handheld device. Foam is formed beneath the slab, providing a gentle lift. Once complete, the holes are repaired and smoothed. With a cure time of only 15 minutes, your home and life are only minimally disturbed.
