Stair step cracks on walls are a common sign of foundation problems caused by settlement and soil issues.
If you've seen cracks in your foundation walls or floors, have bowing or buckling walls, or are dealing with uneven floors, your first instinct is to blame the foundation and the way it was built. However, the real cause of the issue may not actually be your foundation, but the soils around it.
When a foundation is dug out and poured, the removed soil is replaced as backfill. Unfortunately, this process can weaken the soil around the foundation and eventually lead to problems. For many homeowners, this is an unknown source of trouble. At Erickson Foundation Solutions, we can identify soil issues around your home and prevent them from causing further issues with your foundation.

This homeowner in Westford, Massachusetts had a cracked concrete pier under a support post. This post supports the addition of the home and the homeowner would like this fixed ASAP. They decided to call EFS for a free inspection.
Design Specialist Justin Wenners found that the pier had a considerable chunk taken off of the top.
Crew Lead Chris Tremblay and his team removed the old concrete pier and installed the new EZ post where the old pier was.
This home was built on an old fill site, and one day began settling at a rapid rate. In total, the home sank 9 inches. We used push piers to stabilize the home and keep it from sinking any further. We were even able to lift the entire foundation and home up almost back to level, without doing any damage to the structure. In these before and after photos, notice how the lally columns are completely detached from the supporting beams in the basement. We lifted the foundation walls on the perimeter, but the slab in the basement itself was still sunken and crumbling. These columns were replaced with Smartjacks.
The home owners who were once distraught and worried about losing their home are now thrilled and happy to have a stabilized home.
A homeowner in Merrimack, New Hampshire, needed some support added to the addition at the back of their home. The addition in the back of their home had been deemed unsafe by the homeowners. They didn't let anyone go into that room for fear that it would collapse. The homeowners decided to call EFS for a free inspection of their addition. Our design specialist recommended installing EZ post to support the addition.
A homeowner in Londonderry, New Hampshire, had to lift their porch up every year for the past five years. They would also want to fill the void under their pool deck. The homeowners wanted a permanent fix so they reached out to EFS. Our production team installed EZ Post and filled the void underneath the pool deck.
This homeowner in Londonderry, New Hampshire had an issue where the supports of their sunroom were failing. They decided to call Erickson Foundation Solutions for a free inspection.
Design Specialist Michael LaMalfa arrived at the home and inspected the sunroom. He found that the supports under the sunroom are sinking and beginning to bow. In addition to inspecting the outside of the sunroom, Michael also inspected the inside of the sunroom. Michael discovered that the sunrooms floors are out of level. Michael recommended to the homeowners that they should have EFS replace the sunroom supports and replace them with EZ posts.
Crew Lead Nick Carelli and his team arrived at the home and began installing temporary posts in order to remove the old posts. After the old posts are removed, the team installed new EZ posts. Using the EZ posts the team was able to level the floor of the sunroom.
This detached barn in Dunbarton, New Hampshire was originally installed on several concrete columns. Over the years, the columns shifted or sunk, leading to the barn becoming unstable. EZ Post helical piers were installed to replace these failing concrete columns and permanently stabilize the barn.
Understanding foundation soils is the key to understanding foundation repair problems. The type of soil your home sits on plays a huge role in the risk of foundation damage you have. Sand and sandy loam soils allow water to pass through, making them more stable and less likely to expand and cause foundation problems. On the other hand, clay soils absorb water, expand, and put pressure on the foundation. This pressure can lead to floor cracks, wall cracks, and other foundation problems.
There are several layers of soil under your foundation, including bedrock, untouched "virgin" soils, and the active zone, which is where foundation problems can happen. The active zone is the area that is affected by moisture and climate change, causing soil to expand and contract. These soil movements can severely impact your foundation, causing bowing walls, wall and floor cracks, and lessening stability. Depending on where you live, the active zone can be a few feet below grade or as much as 30 feet below the surface. Our foundation repair services can solve a wide variety of foundation soil problems.
The soil under your foundation is comprised of several different layers, some of which were disturbed when your foundation was originally dug out. When one of these layers can't support the weight of your foundation, it will begin to sink and settle. This is a slow process that will not be immediately obvious, but over time it can have serious effects on your home.
Common signs of foundation settlement include floor cracks, stair-step cracks in walls, cracks in interior drywall, and windows and doors that are difficult to open and close. Foundations usually settle unevenly, causing damage to walls and floors that can eventually lead to failure if not addressed. We use foundation piers to stabilize settling foundations and provide a long-lasting solution.
Foundation heave occurs when soils under your home expand and force the foundation upwards. This process is generally caused by over-saturation of soil. Underground water, prolonged or heavy precipitation, poor drainage, and frost heave can all be causes of foundation heave. Foundation heave will cause cracks in floors, bowing walls, and sticking windows and doors.
It's important to note that although the symptoms of foundation heave and foundation settlement are very similar, the causes are very different and the solution for one won't work for the other. One easy way to spot heave is to examine floor cracks and see if they form an enclosed loop. The area inside that loop is where the greatest pressure is being exerted. In order to fix foundation heave, we use solutions such as improved drainage, soil stabilization with polymer injections, and mechanical foundation repair.
When your foundation is dug out, the removed soil is backfilled into the empty space once the foundation is poured. Backfill behaves differently than "virgin" soil because it no longer has the tightly packed, watertight properties that undisturbed soil develops over decades and decades. When excess moisture enters backfilled soil, it expands and exerts pressure on your foundation walls. This is known as hydrostatic pressure, and it can cause serious damage to your foundation walls.
Foundation walls that are subject to pressure from expansive soils will bow inwards and develop cracks. If too much pressure builds up over time, the foundation walls could eventually fail. We can repair this problem with our wall anchor system, which will stabilize the wall by tying it to stronger soils and preventing inward movement.
If your foundation soils are causing cracks in your foundation, bowing or buckling walls, sticking windows and doors, or any other foundation issues, call the local experts at Erickson Foundation Solutions today. We can solve all types of foundation repair problems caused by foundation soils.
