Basement Waterproofing

Basement Water Damage

When your basement undergoes water damage it can become the perfect breeding ground for several different molds as well as other problems. If water sits in there for an extended period, it may sink down into your foundation and disrupt the structural integrity of your home and put your family at risk. Fortunately, our experts are well-versed in dealing with the effects of water damage in a basement and can offer tailored solutions for your situation.

Foundation Waterproofing

If you notice pools of water surrounding the edges of your foundation after a heavy rain fall, it may be time for foundation waterproofing. This can also lead to your home experiencing structural problems. This arises from not including the appropriate measures to waterproof the foundation during initial construction. We offer a variety of solutions to help keep your basement dry and your foundation waterproofed permanently.

Basement Sump Pump

As Wilmington experiences year-round rain, it isn’t uncommon for basements to flood. To prevent moisture-causing damage, it is imperative to install a sump pump. When water flows into your basement, it is collected first by an interior drainage system. The water then trickles down to the sump pit where a float switch is triggered by water reaching a certain level. Afterwards, the water drains out of your home through a discharge line and is directed far away from your basement

Crawl Space Repair

Crawl Space Mold

For mold to thrive in an environment, it needs moisture and organic materials to feed off which are both found in your crawl space. Knowing that your home is having mold issues can be scary as it can lead to health concerns and in worse case, structural problems. One of the major concerns is its ability to weaken wood over time since it is an organic material. To address the issues mold is causing, it’s important to tackle the root cause. The underlying cause of mold anywhere is moisture.

The Stack Effect

Also known as the chimney effect, the term refers to the process by which warmer, lighter air rises while colder, denser air sinks. This can lead to mold spores spreading throughout your home, as well as an increase in energy bills because of elevated humidity. The main reason this happens within your crawl space is because of open vents and unsealed doorways. By covering your property’s crawl space vents and encapsulating it from moisture, you’ll prevent your home from experiencing the Stack Effect.

Crawl Space Encapsulation

The process of encapsulating your crawl space is a technique that seals out moisture, as well as deters pests and other insects from getting in. To begin this, our experts will inspect the condition of your crawl space, fix any prior issues, and then seal it up with a 20-mil plastic vapor barrier, making sure that its safe from the elements. Giving your home a permanent solution to water damage and peace of mind for your family.

Concrete Lifting

Commercial Concrete Repair

At Groundworks, we offer PolyRenewal™, a proven solution to lift and stabilize uneven concrete slabs, such as sidewalks, driveways, roadways, and warehouse floors for commercial properties. PolyRenewal™ uses a two-part urethane polymer that expands into high-density foam to fill voids, lift and stabilize concrete and solve a wide range of geotechnical and structural applications.

Sidewalk Repair

Every day, the sidewalks and walkways around your home experience constant wear and tear. When the soil underneath the concrete slabs starts to shift or settle, it can lead to cracking and sinking, resulting in uneven slabs, and tripping hazards. Voids or gaps in the soil can be due to erosion, rainwater runoff, or intruding tree roots. Thankfully, we can fill and lift your cracked and sinking sidewalk to ensure it doesn’t sink any further, instead of having to repour it completely.

Concrete Step Repair

If you’re dealing with cracked or sinking steps, concrete lifting with PolyRenewal™ is a practical and affordable solution. The concrete around your home can sink or settle due to loose soil, tree roots, or water damage over time. Since PolyRenewal™ foam injections only take 15-20 minutes to cure in the right conditions, you’re able to use your steps the same day, without disrupting your entire landscape.

Frequently Asked Questions

Soil erosion is defined as a natural occurring process in which soil wears away due to an external factor. Soil erosion is extremely detrimental to your property because it displaces the soil that is supposed to be holding up your home. Without the soil, your foundation is at the mercy of any extra weight, pressure, or movement that comes from within or outside your home. Soil erosion can cause settling, ruin the way water flows through your property, and allow for the over-saturation of soil. All in all, it’s a pretty disruptive occurrence for a homeowner.

Sagging floors is one of those problems homeowners don’t usually see to right away. Sometimes, the floor begins to sag slowly over time, so it may not seem like a big deal as homeowners become accustomed to walking on an uneven floor. Other times, the thought of having to replace the floorboards and wooden joists is such a hassle that homeowners would rather put it off for later. However, did you know that if you act fast, not a single piece of wood in your foundation needs to be replaced? It all depends on what’s causing the sag and how quickly you’re able to fix it. One of the reasons your floor is sagging is because of damaged wood. This can be either due to breakage or due to wood rot. If it’s wood rot, you can kill the mold if it hasn’t softened up the wood significantly. To make sure the wood rot is completely gone and to protect yourself from manipulating dangerous chemicals yourself, contact an expert who can eliminate the rot and coat the wood with a primer to strengthen it. Another reason your floor is sagging would be due to foundation settling.

Uneven concrete slabs are pretty dangerous on their own, but things get even riskier if it’s an uneven pool deck. The settling that occurs around pool decks are more likely to cause accidents because of the water, and those that don’t know how to swim run the risk of falling into the pool. But what exactly causes uneven pool decks? Is it the same thing that causes concrete settling in your driveway or garage? Well, sort of, but there’s a bit of a twist to it that involves the pool’s construction. A pool is made by digging a hole large enough to fill a pool. Once all the walls are put into place, soil is backfilled around the excavated area until there’s no sign of the hole. The problem with this is that while the soil surrounding the pool is compacted, dense, and capable of holding up the pool, the soil that’s used as backfill is very loose. Because of the soil’s looseness, when the concrete slabs are poured over the soil, it compresses together, forming a gap under the concrete that causes settling. There’s very little that can be done about this during the construction of the pool itself, so all you can do as a homeowner is repair the settled slabs.

The Wall Anchor System permanently stabilizes your foundation walls, offering the best opportunity to straighten the walls without the cost and disruption of foundation replacement. Heavy-duty, galvanized earth anchors are embedded in stable, undisturbed soil outside your foundation wall. Each anchor is connected by a steel rod to a wall plate that provides clamping pressure against the inside of the foundation wall. This method also offers the potential to straighten the wall back to its original position. Wall anchors are the most versatile wall repair method because they can be used to stabilize walls with a variety of problems, including bowing walls, tipping walls, and walls that are pushing in at the bottom. Wall anchors are installed independently of a home’s floor systems, making them the ideal installation under appropriate conditions. In order for a wall anchor system to work effectively, several feet of access is needed on the outside of your home. In areas where homes are only a few feet apart, wall anchors are not a valid option. If this is the case in your situation, we will recommend another wall repair option.
