Basement Waterproofing & Foundation Repair Service in Dover, DE

If your Dover home is experiencing problems with the foundation, crawl space, or basement, it may be due to the problematic soil that it rests on or the unpredictable climate.

Located on the St. Jones River in the Delaware River coastal plain, Dover experiences a warm temperate climate in the summer, and brief, but heavy thunderstorms are common. Winters are usually moderate, with light snowfall throughout the season. The prominent soil type in the area is Greenwich and is mostly comprised of well-drained clay. Since the summer season can bring heavy rain, this can lead to your foundation, basement, or crawl space getting flooded, resulting in serious structural damage. If you are experiencing problems with your home’s foundation, a wet or leaky basement, or structural problems with your crawl space, let the experts at BQ Basements & Concrete help. Our proven, warrantied solutions can help restore your home back to its original state and bring you peace of mind for years to come.

Basement Waterproofing in Dover, DE

Basement Water Damage – If you notice musty odors or elevated humidity when you step into your basement, you may have an issue with water damage. This can be from faulty plumbing, wall cracks from hydrostatic pressure or flooding after a heavy rainfall. At BQ Basements & Concrete we offer proven solutions to help repair and restore the damage in your basement by installing interior drainage and sump pumps; to covering the walls with a vapor barrier.

BasementGutter™ Interior Drainage – Choosing to install our BasementGutter™ Interior Drainage can help guarantee your home is well-equipped to deal with any water that comes its way. If your basement regularly experiences flooding or pooling water near the cove joint where the walls and floor meet, this could be the right system for you! This proven solution stops and directs leaking water to a sump pump to ensure it stays dry and moisture-free.

Basement Sump Pump – Many homeowners believe that installing a sump pit and a sump pump won’t help solve their water issues, and this isn’t the case. Our superior sump pump system gives you peace of mind when and if water begins to leak into your basement. By pumping the water collected by the interior drainage system through a discharge line and away from your home, you won’t have to worry about water destroying your basement area and causing other related issues.

Crawl Space Repair and Encapsulation in Dover, DE

Crawl Space Mold –Unfortunately, mold tends to spread throughout crawl spaces that are wet and damp since it’s the ideal environment for it to thrive in. As it feeds off the wood that makes up your floor joists, it leads to decay and rot and other serious structural issues. At BQ Basements & Concrete, our experts can waterproof your crawl space and seal out any moisture, preventing mold growth from happening again.

The Stack Effect – As warmer, lighter air rises and colder, denser air sinks, this creates what is known as the stack effect. This phenomenon leads to the air in your crawl space being circulated all throughout your home and eventually finding its way out through your roof. This can result in the spread of mold spores, elevated humidity, and other toxins within the air you breathe. If you have uncovered crawl space vents, the professionals at BQ Basements & Concrete can install a high-quality cover to put a stop to the stack effect.

Crawl Space Encapsulation – By encapsulating your crawl space from moisture, pests, and other natural elements like mold, it prevents your home from experiencing damage in the future. By having crawl space vents that are open, as well as no vapor barrier in place, it puts your home’s environment and structural stability at risk. When our experts encapsulate your crawl space, you can be sure it is being protected from the damaging effects of moisture, humidity, mold, and pests, and stays dry and clean.

Foundation Repair IN Dover, DE

Sinking/Settling Foundation – When the soil under your home can no longer hold the weight of your home, your foundation may begin experiencing issues with sinking and settlement. This can arise from loose backfill soil during construction, excess ground moisture content, and maturing vegetation within your landscape. To stop this from causing any more damage, our team of experts can restore your foundation by installing heavy-duty steel piers under the footing of your home’s foundation.

Tilting Chimneys – Tilting chimneys are usually correlated to foundation settlement, as they begin to separate from the rest of your home due to changes in the soil underneath. Some key signs of this happening are leaning or tilting, gaps between the chimney and your home’s walls, and cracks along the joint with the foundation. At BQ Basements & Concrete, we’ll install our helical pier system to lift your chimney back to its original position.

Wall Straightening – Our wall anchors or SettleStop IntelliBrace™ Wall Repair System will permanently repair and stabilize your failing foundation walls. If you’ve come across this problem in your home, it may be because of problems with your foundation settling into the soil, causing walls in your home to shift, and become unstable.

Driveway Repair – When you begin to spot cracks, sunken concrete, and uneven slabs, it’s time for a driveway repair. Fortunately, the specialists at BQ Basements & Concrete can quickly and effectively repair your driveway by lifting the concrete, rather than tearing out and replacing it. Using our proven solution process called Poly Renewal™, we’re able to raise the existing concrete slab back to its original position and you’re able to use your driveway the same day.

Interior Slab Lifting – If your basement floor is sloping or uneven, it may be time to restore your floor’s integrity with interior concrete slab lifting. Over time, the concrete slabs within your home will settle and sink, causing severe structural damage if left unrepaired. At BQ Basements & Concrete, we provide quality interior slab lifting with PolyRenewal™, a non-invasive solution that can lift your concrete slab back to its original position.

Sidewalk Repair – When soil underneath your sidewalks or walkways begin to erode, or roots from nearby trees intrude, the concrete slabs will begin to crack and become uneven, or in worst cases, break away. Although this is a common phenomenon, it presents a dangerous tripping hazard to anyone using it, as well as lowers the aesthetic value. Fortunately, our experts at BQ Basements & Concrete can fill and lift your cracked and sinking sidewalk by using our proven PolyRenewal™ foam injections.

About Waterproofing, Crawl Spaces & Foundation Repair in Dover, DE

The soil immediately surrounding your foundation is a lot looser than the soil farther away. This is because when your home was built, a bowl-like hole was excavated, and the foundation was built in this space. After the foundation was built, the gaps were backfilled with the soil that was previously removed. The problem with this is that the soil used as backfill is a lot more porous that the densely packed soil the foundation sits on. This porous soil is able to absorb a lot of water, making it a dangerous threat to your foundation. The clay bowl effect is something many homeowners in Dover have to worry about. This problem is incredibly persistent in areas where the soil is primarily made of clay. These soils already have a high expansion capacity, but in a state like Delaware, the soil is capable of getting saturated quite easily. When it rains, not only does the rainwater directly affect the soil, it also raises the water table. Because of the soil, the weather, and the clay bowl effect, foundations in Dover are in constant need of repairs.

A good way to determine whether your basement or crawl space has high humidity levels is to check if the concrete has efflorescence stains. Efflorescence is a white, powdery substance on the surface of concrete. If you touch it or scrape it, it feels grainy and some of it flakes off. At times, homeowners will confuse efflorescence for mold, but this is incorrect. Efflorescence is salt, which you can feel the texture of if you scrape it off the concrete.

Efflorescence appears on your concrete either due to primary efflorescence or secondary efflorescence. Primary efflorescence usually occurs 48 to 72 hours after the concrete is poured and it’s a result of an excess amount of water in the cement mixture. As the cement cures, the water evaporates and rises to the surface of the concrete but brings along with it all the salts and minerals from the cement. Even professionals get a bad mixture from time to time, but an experienced contractor is less likely to make cement that produces efflorescence.

If you’re looking for the best way to lift your settled concrete slab, look no further than polyurethane injections. This concrete lifting system utilizes polyurethane foam to lift concrete back into place. Small holes are drilled into the concrete in order to inject the polyurethane foam until there’s enough under the slab to lift and support it. This is a modern, innovative approach to concrete lifting that solves every problem associated with traditional methods. What makes this method so great is all about what the material is made with. Mudjacking, the traditional method of concrete lifting, consists of pumping a cement slurry under the concrete to lift the slab. However, because of how heavy and rough the cement is, it puts pressure on the soil below, increasing the chances of displacement and settling. The cement is also too rough to properly fill the gap under the slab, so some parts remain unsupported after the job is done. Mudjacking is also rather tedious because it can take hours for the work to be completed and you still need to wait hours more for the cement to cure before putting any pressure on the slab. Polyurethane foam eliminates all those inconveniences.

Having a beautiful, healthy tree growing on your property makes your yard look interesting and visually pleasing. However, there’s a good chance that your tree is ruining your foundation and causing those pesky leaks in your basement or crawl space. Many homeowners misunderstand how a tree is able to do so much damage and believe that the tree roots themselves are the issue when it’s actually the soil. Like most problems pertaining to foundation damage, expansive soils are the culprits, not the tree roots. The characteristics of clay soils make it so trees encourage shrink-swell capacities and soil displacement.
