Foundation Repair and Waterproofing
This is the H2
Exterior Wall Crack Sealing
Arrow Foundation Repair provides basement crack repair. Depending on your situation, one method of crack repair is to seal the crack from the outside of the wall. The area outside of the crack is excavated to expose the foundation crack. The concrete wall is then cleaned, a flexible polymeric waterproofing membrane is applied over the concrete crack and the excavated area is backfilled. This method prevents water from getting to the crack. It also prevents water from entering your basement if there is any future movement which compromises a sealed crack.
Epoxy Crack Repair
Epoxy crack injection is a common way to fix basement wall cracks, but keep in mind that epoxy injection crack repair does not fix the source of the water problem. It’s important to identify and solve the water and drainage issues to permanently stop water from seeping into your basement. Epoxy is extremely strong – stronger, in fact than the basement walls themselves. Epoxy injections can fix cracks of many sizes and have the ability to fill even the smallest of wall cracks. A primary advantage of epoxy is its high compressive strength. This is the main reason why engineers will recommend epoxy injections for many structural foundation repairs. Epoxies are used in many applications, from commercial and industrial buildings, residential structures, even major infrastructure such as bridge and highways. This method of basement wall repair seals the foundation and creates an impervious barrier to basement water seepage.
Interior Drain Tile
A drain tile system is a network of drain pipes and gravel installed around the foundation of your home or commercial structure. The pipes are perforated so that water that collects around and under your foundation drains into them. The pipes then run the water into an interior sump pit.
The sump pit contains a sump pump that automatically pumps out the water away from your house. Homes without a drain tile system, or with a clogged or failing drain tile systems, often find their crawl spaces and basements flooded. Interior drain tile systems are part of a complete drainage solution to control water issues around and under the foundation and is the best solution to address hydrostatic water pressure frequently present under basement slabs and outside of foundation walls.
Leaky basements occur for a number of reasons. First, groundwater collects under or around the foundation of your home. Hydrostatic pressure refers to a water pressure and is a major cause of basement water problems.
Hydrostatic pressure increases in proportion to depth measured from the surface, because the increasing weight of fluid is exerting downward force from above due to gravity. When there is enough hydrostatic pressure, the water will find a way in… either through a crack, seam, or through a wall or floor slab. Hydrostatic pressure can easily drive groundwater into the basement through gaps and cracks in the masonry. High water pressure can also cause seepage through solid concrete.
Secondly, if you have a blocked or failing drain tile system, the water will have no way to be drained away from your foundation. Just like groundwater, this rainwater will find a way into your basement. Finally aside from groundwater and rainwater basement leaks, many leaks are the result of wall cracks, which can let in any type of water or moisture into your basement.
A foundation waterproofing membrane is a waterproof barrier for your home’s foundation. Most of these waterproofing membrane products are rolled-sheet products that are fastened to the concrete wall after application of a primer or liquid adhesive that can be applied manually with a roller or with spray equipment. Liquid membrane can also be applied with a roller or a sprayer and when it cures, the membrane becomes a single seamless coat that does an excellent job waterproofing your home. Most waterproofing membrane sealants have a high degree of flexibility, so they can stretch with heating and cooling expansion and contraction – and even stretch to cover cracks that form after the initial application.
Basement Waterproofing Systems
A basement waterproofing system refers to a combination of the above waterproofing fixes and prevention techniques. These types of systems are unique to each home or structure and must be customized to ensure that water around the foundation does not enter, and that water that collects around the basement foundation is collected and drained properly. A complete system often includes downspout drainage, french drains, berms, swales and/or other custom surface drainage methods depending on your home’s unique water drainage issues.
Foundation settlement problems are common in many parts of the country, but here in Kansas City, our hot summers and cold winters combined with dry spells and periods of heavy rain make our area especially vulnerable to foundation issues. Foundation settlement problems are common, mainly because homes and buildings are heavy and some types of soil have a poor load-bearing capability. Foundation settlement can happen over time when soil settles or erodes because of rain or water leaks. Signs of foundation settlement include:
- Concrete stairs that sink or tilt
- Leaning or tilting chimneys
- Vertical cracks in concrete foundation walls
- Cracked stone veneer or exterior stucco
- Cracked and sinking slabs
- Cracks in drywall around window & doors
- Doors & windows that are hard to open and close
Foundation settlement repair solutions typically include some form of underpinning or piering including concrete piers, steel pier foundation repair and helical pier foundation repair.
Bowed Basement Walls
Bowed basement walls are caused by too much ground pressure pushing against your basement walls. When rainwater is absorbed by the soil around your basement foundation, the soil expands as it absorbs water and pushes against your exterior basement walls. When the soil dries, it moves away from your foundation walls again. This cycling of expansion and contraction creates bowing and weakens your basement walls. Arrow Foundation Repair provides several solutions for bowed walls:
- Wall Bracing
- Tie Backs
- Concrete Tie Backs
- Steel Plate Tie Back
- Helical Torque Tie Back Anchors
In some cases when bowed walls represent a more serious problem, Arrow Foundation Repair may recommend wall straightening. In simple terms, basement wall straightening involves pushing or pulling your foundation walls back into place. In order to apply this solution, we need to excavate the soil down to the foundation’s footing. Then we repair and straighten the wall. Since the foundation is exposed it’s often cost-effective to address the issues including fixing the cracks, applying a basement waterproofing membrane, and installing or repairing your drain tile system.
If your house has basement walls that are cracked, leaning or bowing, you likely have a serious foundation issue that needs to be resolved. A bowed, cracked or buckling foundation wall often raises great concern for homeowners and the thought of contacting foundation repair companies in Kansas City can be intimidating. Many of our Kansas City homeowner customers are relieved to find out that an Arrow Foundation Repair engineered wall support system can permanently fix their failing basement walls at a fraction of the cost of many other foundation repair methods. Wall anchoring involves using galvanized anchors that are buried out a considerable distance from your foundation walls. These anchors are steel wall plates with anchoring rods. The plates and anchors will hold your basement wall in place, and depending on the system used, can be adjusted to straighten a wall over time.
As discussed in other sections, foundation settling is more and more common. Older homes settle over long periods of time and their foundations are often weaker than new homes with advanced foundation and concrete technologies. Newer homes, however, are being built on unstable soils – so while the foundation and basement wall may be stronger, the earth which they rest on may not be. In either case, foundation issues are becoming more common. Foundation piering (also known as underpinning) is the process of attaching steel piers to the foundation of your house to keep it from sinking further, or to keep your foundation in place after it has been raised or fixed. In order for the steel foundation piers to be permanently effective, they often need to be installed deep into the earth to reach bedrock or load-bearing strata. Arrow Foundation Repair is Kansas City’s leader for this type of foundation repair.
Crawl Space Repair
Crawl space repair often referred to as crawl space encapsulation is a foundation repair industry term used to describe a crawl space that is equipped with a moisture barrier on the floor and walls of the entire crawl space area.
By recovering and sealing your crawl space, you can keep out insects and critters. More importantly, crawl space encapsulation helps to improve air quality, reduce energy costs, and keep moisture out of the area – which in turn reduces the chance for mold, mildew and other problems that sub-surface moisture can create for your home. Encapsulation typically involves cleaning and prepping the area, installing a vapor barrier, and sometimes even installing a humidifier and/or an interior drain tile and a sump pump to collect and remove water away from the crawl space area.
Heaving refers to the upward movement of a basement foundation or concrete slab. While there are several root causes, the end effect is that underlying soils expand or swell and push the concrete out of place. Heave is more common with slabs than foundations because slabs (like floors, driveways, and sidewalks) are lighter and often at surface level. Heave most commonly occurs within the first few years of the building’s construction but can also occur after extended drought conditions. Slab and foundation heave is most commonly caused by:
- Expansive Soils
- Tree Roots
- Frost Heave
- Plumbing Leaks
- Long-Term Precipitation
- Poor Drainage

Helical anchors and helical anchor tiebacks are hydraulically installed to a predetermined torque to support the weight of your house. Our patented brackets are then installed to support the structure.
Crack Injection Repair
Foundation cracks can be caused by many things – poor construction materials or workmanship, shifting earth caused by an excess of rain or fill dirt settling, etc. Cracks in a basement foundation or crawl space wall can allow water into your home. What’s worse is if these cracks get water in them that freezes in the winter. The frozen water expands increasing the damage to your foundation and making the crack worse. If you see cracks in your basement walls, don’t put it off. The sooner you repair the crack, the less damage and expense you will have to deal with. And we are concrete crack repair experts! Here are two services we provide:
Interior Wall Epoxy Crack Sealing
A foundation wall crack can be sealed from the inside with either an epoxy injection or polyurethane injection. This method of concrete crack repair is fast, easy and inexpensive. We fill the crack with a strong epoxy that seals the edges and keeps water out. The downside to this approach is that there is little allowance for further movement of the wall without the seal being compromised. It’s a quick fix to keep water out, but it won’t last forever if there is more movement.
Exterior Wall Crack Sealing
Another service we have for basement crack repair is to seal the crack from outside of the wall. The area outside of a crack is excavated to expose the entire crack. The wall is cleaned, an adhesive polymeric membrane is applied over the crack and the excavated area is backfilled. This approach stops water from getting to the crack and will not allow further movement of the wall to compromise the seal.
Do you have a sagging crawl space beneath your home? What starts in the crawl space doesn’t stay in the crawl space. Half or more of your basement air flows upward into your house, bringing odors and mold spores with it. Pests also will travel into the upper levels of the house to find warmth and food. If these problems become severe enough, they could put your family’s health at risk. Arrow Foundation Repair can offer a crawl space encapsulation system that seals out moisture and blocks unwanted pests. A piering solution will also stabilize and reinforce the structure on which it sits.
