Basement Waterproofing in Denver, Colorado

Like your foundation, your basement is also affected by the bentonite clay in the Denver area. The clay-like soil can become saturated during times of heavy rain after a drought or excess snowmelt. This creates pressure against your basement walls and floors. Issues like basement water damage and water buildup will occur as a result of cracks formed by the pressure. These problems lead to even more damage like wet drywall and flooded stairs. Basement waterproofing is the key to a dry basement. We offer basement dehumidifiers to remove excess condensation, as well as basement sump pumps to remove large quantities of standing water. 

Foundation Repair in Denver, Colorado

Bentonite soil makes your home’s foundation very shaky, and the harsh weather in the area further contributes to a foundation in disrepair. In addition to the soil conditions, Denver experiences periods of drought, which causes the soil to shrink, creating cracks along your foundation. Foundation settlement is a dangerous problem that can lead to additional issues like sticking windows and doors, and even a tilting chimney. We offer a plethora of solutions that are designed to stabilize your foundation. Foundation piers prevent further settlement, while wall anchors work to stop your walls from bowing and cracking.

Crawl Space Encapsulation & Repair in Denver, Colorado

Denver’s soil – known as bentonite clay soil – is very expansive and unstable. This instability negatively affects your crawl space, causing sagging floors and other structural damage. Denver experiences hot summers and cold, dry winters; however, the ground freezes. The freezing and thawing cycles that occur leave the soil saturated with water. If your crawl space has not been encapsulated, which includes the installation of a vapor barrier, insulation, and more, then you will notice problems. Mold, high humidity, and water in your crawl space are telltale signs something is wrong with your crawl space.

Concrete Lifting in Denver, Colorado

Due to the instability of the soil in Denver, the concrete around your home can start to crack and sink into the soil. Soil washout is also common in the area due to the bentonite soil. The harsh winters and wet fall seasons will cause some concrete deterioration like pitting, flaking, and staining. Our innovative PolyRenewal™ polyurethane injections repair your home’s concrete by filling in gaps, expanding, and lifting the concrete in as little as 15 minutes. Repair your damaged concrete before someone is harmed from tripping and falling on the uneven concrete structures around your home.

While concrete damage can be caused by a variety of things, most of them boil down to what is underneath the concrete – the soil. The soil acts as a foundation for the concrete, and when there is a problem with one, that means there is a problem with the other. Because soil is exposed to the elements, it can take on various damage. Soil tends to shrink when it is dry and become too compacted when there is too much weight placed upon it. Both of these instances can lead to soil settlement beneath the concrete.

Building code typically calls for homes with crawl spaces to have vents. This was meant to allow for better airflow to reduce the chance of elevated humidity and mold growth. However, foundation experts have found this to be a detrimental process that causes the very problems open vents were meant to avoid. A vented dirt crawl space allows outside air, water, pests, and other nuisances into the crawl space. This results in a dirty, unhealthy area that also affects the rest of the home. Things like mold spores and pest dropping odors can circulate in the air throughout your home because of the stack effect.

The stack effect can impact your home especially if you have a vented dirt crawl space. Outside air, water, and pests enter the crawl space through the open vents. Any unhealthy conditions like high humidity, pest droppings, unpleasant odors, mold spores, and mold growth can circulate in your home as warm air rises from your crawl space. So, whatever is in your crawl space is also in your home and affecting you and your family.
