Foundation Repair Contractors in Dundalk, MD
Walk into the basement of a mid-century Dundalk home and you will usually find a concrete block foundation wall, laid when the town was growing up around the Sparrows Point steel mill. Block is strong under the weight of a house, but it has a weakness: it does not handle sideways pressure well. Years of wet clay pushing against the outside, and frozen soil adding to the load each winter, can leave those walls cracked, leaning or bulging inward, sometimes slowly enough that the change goes unnoticed for a long time.
Best Buy Waterproofing provides foundation repair in Dundalk, MD for bowing walls, cracked block, settling corners and the floor problems that come with them. Our in-house crew stabilizes walls with carbon fiber straps or steel I-beam wall braces, rebuilds block sections that have failed and installs push piers or helical piers under settling foundations. Because we also do waterproofing, we can deal with the water pressure that often caused the damage, so the repair holds up.

Foundation Repair Solutions for Dundalk Homes
Stabilizing Bowing Basement Walls
Bowing basement walls are one of the most common structural problems in older block foundations. On the low ground around Dundalk, the soil against a foundation can stay wet for long stretches, and wet clay swells and pushes inward. Freeze-thaw cycles add more pressure every winter. Block walls tend to respond with a horizontal crack partway up, stair-step cracks near the corners or a visible bulge, and the movement usually continues if nothing is done.
Wall stabilization holds the wall in its current position so it cannot keep moving. We measure how far the wall has shifted and recommend the method that fits, from carbon fiber straps for early movement to steel braces for walls that need more support.
Carbon Fiber Straps for Early Movement
When a wall is cracked or has bowed only slightly, carbon fiber straps are often the right fit. The straps are bonded to the inside face of the wall with a high-strength epoxy and secured at the top and bottom. Carbon fiber is very strong for its weight, so the straps resist further inward movement while staying thin and close to the wall.
That low profile suits narrow rowhouse basements. Straps can be painted, and they leave the wall ready to finish later. No digging outside is required.
Steel I-Beam Wall Braces
Walls with more noticeable bowing need more support than straps can give. Steel I-beam wall braces run vertically from the basement floor to the floor framing above and are secured at both ends. They brace the wall against the soil pushing on it and keep it from moving further inward.
Wall braces are installed entirely from inside the basement, so they work well for Dundalk rowhouses and duplexes where there is no room to dig along the outside wall. We space them based on the length of the wall and how far it has moved.
Rebuilding Failed Block Walls
Some walls have moved too far to be held in place. If a block wall has sheared at the base, leaned badly or broken into loose, crumbling block and mortar, stabilization alone may not be reliable. In that case, we temporarily support the house, remove the damaged section down to sound material and lay new block back up to the framing, tied into the existing wall.
We only recommend a rebuild when the inspection shows the wall cannot be stabilized. Because water pressure is usually behind the failure, we also look at drainage so the new wall does not face the same conditions.
Push Piers for a Settling Foundation
A settling foundation looks different from a bowing wall. Instead of pushing inward, part of the house sinks, often at a corner where downspouts dump water or where soil has softened or washed out from under the footing. The signs include cracks that are wider at the top, sloping floors and doors that no longer close cleanly.
Push piers are steel pipe sections driven down beneath the footing until they reach firm, load-bearing soil. The weight of the house is then transferred onto the piers, which helps stop further sinking and can sometimes lift the section back toward its original position.
Helical Piers for Lighter Loads
Helical piers are steel shafts with screw-like plates that are turned into the ground until they reach soil that can carry the load. They work well for lighter structures and for spots where push piers are not the best fit, such as porches, additions and some smaller homes. On layered Coastal Plain soils, finding firm bearing below the soft upper layers is what makes either pier type effective.
We recommend push piers or helical piers based on the weight of the structure, the soil and access around the foundation.

Foundation Repair FAQs
Is a horizontal crack in my block wall serious?
Usually, yes. A horizontal crack in a block wall typically means soil pressure is pushing the wall inward, and the movement tends to continue. It is one of the most common warning signs we see in older Dundalk basements. A free inspection measures the wall and tells you whether straps, braces or a rebuild is the right fix.
Can foundation repair be done in a rowhouse basement?
Yes. Carbon fiber straps and steel I-beam wall braces are both installed from inside the basement, so no digging is needed along the outside of the wall. That makes them practical for rowhouses and duplexes with little yard space. We plan the layout around your stairs, utilities and the room you have to work with.
Can a bowing wall be pushed back to straight?
The goal of wall stabilization is to hold the wall where it is and stop further movement, which protects the house above. A wall that has moved too far, or whose block is breaking apart, may need a section rebuilt instead. During the inspection, we measure the bow and tell you what is realistic for your wall.
What is the difference between push piers and helical piers?
Both carry a settling foundation down to firm, load-bearing soil. Push piers are driven beneath the footing using the weight of the house and suit most heavier structures. Helical piers are screwed into the ground and work well for lighter loads like porches and additions. We recommend the type that fits your home and soil.
Why did my foundation start moving after so many years?
Foundation problems build slowly. Years of wet soil, freeze-thaw cycles and changes like a clogged gutter or a new patio that sends water toward the house can tip a wall from stable to moving. On low ground, where soil stays saturated after storms, that pressure is hard on older block walls.
Should I fix the water problem before the foundation?
Often both should be planned together. Water pressure is usually what makes walls bow, so stabilizing a wall without addressing drainage leaves the cause in place. Our team does both foundation repair and basement waterproofing in Dundalk, so we can sequence the work and avoid redoing anything later.
