Foundation Repair

Common Foundation Problems

Foundation problems are more than an eyesore; they can put your home’s safety and value at risk. Foundation problems are a required disclosure when selling your home. What might start out as a small crack, a very slight sag in the floor or some surface moisture gathering, could grow into a very expensive repair.

When your home was built, the foundation should have been properly set on compact, load-bearing soil. Over time, and with the seasons, that changes, shifting moisture levels and temperatures causing loosening soils to expand or contract, exerting significant hydrostatic pressure. That process is often accelerated by changes outside your home, including erosion, tree growth and new structures. This can lead to a number of foundation problems, including sinking or heaving floors, buckling, bowing and cracking walls, basement water issues and leaning chimneys.

Thrasher’s team of certified foundation repair experts is backed by 45+ years of experience and a team of structural engineers. We offer unparalleled expertise, superior installation methods and patented, industry-leading products and processes that set the standard for foundation repairs everywhere, all backed by the best, transferrable warranties.

Sunken Foundation Repair When your basement floors or walls are sinking, sunken foundation repair restores them to their original position and repairs any damage, restoring your home’s structural integrity. Sunken foundation repairs often require push or helical pier solutions, shifting the weight of your home onto brackets and hardening unstable underpinning soil with injections.

Foundation Crack Repair Repairing foundation cracks will restore your foundation’s structural integrity, waterproofing your basement and preventing moisture, foul odors and other infestations from coming in. Wall anchors, braces or carbon fiber straps are common solutions for wall cracks, while push or helical piers are common repairs for floor cracks, but every foundation crack repair system is as unique as your home and the ground holding its footings.

Leaning Chimney Repair One of the heaviest structures of your home, a leaning chimney can leads to gaps in your siding or foundation, falling bricks or most dangerously, combustible gas leaks. Depending on the specifics of your chimney, the ground underneath and its connection to your home’s foundation piers, smart jacks and wall braces can help straighten a leaning chimney.

Street Creep Repair As concrete street and pavement around your home expands in warmer weather and contracts in colder weather, debris can fill the cracks in between sidewalk, street or driveway slabs, gradually negating expansion joints that would normally absorb the change in pressure and creating a very slow but very powerful force on your garage and foundation walls and floors. Installing new expansion joints and reinforcing walls with anchors can repair this street creep.

Foundation Repair Solutions

Your entire house sits on its foundation, so making sure your home is structurally sound and protected starts with making sure its foundation is solid and intact. When your foundation needs repair, you are protecting your biggest investment, as well as the health and safety of its occupants. Ignored too long, you risk foundation collapse, causing significant structural issues and very expensive and time-consuming repairs.

Foundations need repairs for a number of reasons, mostly involving improper construction, drainage issues and hydrostatic pressures created by soil in the moisture expanding and contracting with seasonal changes over time. The first signs your might need foundation repairs can be fairly minor – a window or door sticking, a small crack in the floor or wall, maybe some moisture gathering or condensing in a window.

As these problems worsen, this can lead to cracking, bowing or leaning walls, as well as sagging or heaving floors, allowing moisture, foul odors and other infestations into your basement. Foundation problems rarely go away and almost always worsen left unaddressed.

Foundation repair solutions are unique to your home and its setting, ranging from anchors, braces and carbon fiber straps for walls to push or helical piers for floors and footings.

Wall Repair Systems Wall repair systems – whether wall anchors, braces or carbon fiber straps – help repair and cracking, buckling and bowing walls, preventing moisture and infestations from getting into your basement and restoring your home’s structural footing.

Foundation Piering Foundation piering systems – often either push pier or helical pier – help repair sagging, sinking or heaving walls and basement floors, shifting weight off of unstable soil onto brackets attached to the piers anchored in compact, load-bearing soil.

Frequently Asked Questions

How long does a typical foundation repair project take and how much of my yard will be disturbed?

A foundation repair project generally takes less than a day to complete with the proper
assessment, trained experts and the right equipment. For repairs that require some yard
disturbance – wall anchors or pier solutions -- a small surrounding area must be excavated,
although disturbance is kept to a minimum, allowing for working in tight areas. The more
widespread foundation problems are, the larger the repair system required, taking extra time.
Once the project is completed, all signs of work will be covered as dirt is put back into place and
landscaping restored.
I want to finish my basement, is there a way to guarantee a dry basement all of the time?

If a foundation is properly set on the right soil, the house sits on a crown so water flows away and the gutters and drainage all properly work, your basement should be dry all of the time. Now,
even if all of these things are true when a home is constructed, it can change over time. To
guarantee a dry basement all of the time, you will have to make sure all of these factors remain
intact over time, requiring extra viligance. Even the best viligance, however, won’t be able to
catch everything, especially changes to the soil alongside and beneath your home, though
proper drainage can go a long way to preventing these changes.
How can I tell where the water in my basement is coming from?

Sometimes the source of water intrusion into your basement is obvious, for instance a clogged
drain, crack in a wall or failing mortar between blocks that allows water to get in. However,
knowing the full path and source of that water leak can take some serious foundation detective
work, requiring a trained expert with the right moisture detection tools. The cold joint, where the
basement wall meets the basement floor, creating a natural seam, is a frequent point of water
intrusion. Hydrostatic pressure, water building in loose soils, can also force moisture through
porous blocks, joints and cracks.
I have some cracks in my foundation and a few in my basement, how do I tell if they are serious?

Many minor cracks are simply visual, and not indicative of serious structural damage. However, to distinguish this from cracks that might show larger problems, you must look at the size and
number of cracks. If cracks are more than 1/8 inch or spanning a large surface area, that's probably serious. If the cracks are growing over time, it likely signals the foundation starting to give way under pressure,which could become a very serious issue.
I have cracks in the drywall on some of my interior walls. What caused this?

Drywall cracks, if not caused by seasonal changes in humidity, may also be caused by structural
problems. For example, poor settlement leading to cracks in concrete slabs often indicates that
sagging walls are next and drywall is soon to follow. If your house is built on uneven soil, the
shifting and sinking will result in cracks forming on your interior walls.
What steps should I take to best prepare my basement for finishing?

There are several precautions to take when preparing your basement for finishing. First, make sure there are no moisture issues, including leaks, pooling water or condensation or dampness gathering on walls or other surfaces. Second, make sure all of the basement walls are plumb (straight vertical) and the floor is flat horizontally. If either of these things are off, that could indicate deeper structural issues that need to be remedied. Third, get your basement checked for radon and take appropriate steps to have any radon mitigated.
