Retaining walls are common along roadways, parking lots, and bodies of water. Basement walls are also a type of retaining wall — and similar repair options are available for both.
Your retaining wall is showing signs of failure.
What is a Retaining Wall?
Retaining walls serve to retain the lateral pressure of soil. More simply, retaining walls are used to hold back soil and substrate from moving due to the effects of gravity and erosion. Retaining walls are typically designed out of concrete, stone, wood (including railroad ties), vinyl, masonry, steel, or brick.
How to Fix It:
We install either a wall anchor system or helical tieback system along the retaining wall to reinforce the structure.
Maintaining a safe and stable home is important to longtime homeowners in Fredericktown, OH. That is why they were motivated to address a worsening structural issue before it resulted in serious damage.
The homeowners noticed the exterior retaining wall adjacent to their garage was beginning to cracking and bow outward. Retaining walls can fail due to a variety of issues including poor construction and hydrostatic pressure exerted on the wall by the soil.
The owners contacted Ohio Basement Authority after seeing one of our TV ads, and we installed some of our many reliable foundation repair products. These included a Helical Pier and two Wall Anchors. Both of these durable products permanently stabilize, straighten, and reinforce the retaining wall.
The homeowners now have peace of mind knowing these reliable solutions have helped them create a safer living environment.
During the last several years, homeowners in Westerville, OH, have been monitoring a potential structural issue outside their home. They noticed a retaining wall outside their basement walk-out was beginning to fail. It was cracking and slightly tilting inward.
The homeowners were not only concerned about their safety, but how these issues could affect the future resale of their house. They were motivated to contact Ohio Basement Authority after seeing our TV ads. After meeting with one of our inspectors, the homeowners were equally excited for one of our crews to fix these problems for good.
First, the crew excavated the earth outside the retaining wall down to the wall’s footer. The wall was then pushed back to as plumb as possible. Then, two Wall Anchors were installed to further straighten and stabilize the retaining wall. Wall Anchor Covers were placed over the visible anchor plates to conceal them, and all cracks were repaired and filled.
The homeowners are pleased this reliable repair solution has helped enhance the safety and appearance of their home.
Signs of a failing retaining wall are usually easy to identify, as shown in the different examples below. The important thing to know is that these symptoms will become increasingly worse over time. Unless proper repairs are made, the wall will eventually fail completely.
Most often, a retaining wall will show signs of failure in one of three ways:
Collapsing/Tilting Retaining Walls
Soil issues and/or poor construction are often the culprits for retaining walls that are tilting. This can happen if the footing toe is too small or if the wall wasn’t properly reinforced. Railroad tie retaining walls can begin to collapse due to wood rot or deterioration.
Most retaining walls require drainage “weeps”. If water accumulates behind the wall, this additional weight can cause clay soils to expand, leading to cracks and tilting.
Retaining Walls Separating From Adjacent Walls
Like collapsing/tilting retaining walls, walls that are separating from adjacent walls are often caused by poor quality construction.
A separating retaining wall may not have been designed to withstand the weight that actually bears on the wall. Poor drainage and inadequate reinforcement or connection to the adjacent wall are other possible causes. In unusual cases, expansive soils may also cause a retaining wall to separate from an adjoining wall.
Crumbling/Failing Retaining Walls
Retaining walls can crumble for a wide variety of reasons, most related to the improper design of the walls itself.
Often, the wall was not designed to bear the weight load behind it. In the case of concrete retaining walls, the issue may be inadequate, weak, or poorly mixed concrete.
Concrete retaining walls may also have been designed with inadequate steel rebar, resulting in insufficient strength.
To repair retaining walls, we at Ohio Basement Authority typically recommend either wall anchors or helical tiebacks to restore structural integrity.
Both wall repair techniques use a strong steel wall bracket on the exterior of the retaining wall to brace the wall and properly distribute the anchor’s clamping pressure.
With both wall anchors and helical tiebacks, your foundation repair contractor will also attempt to return the wall to its original position, restoring its appearance and structural integrity.
Wall anchors accomplish this by driving an anchor rod through 1″ holes driven into the retaining wall. These rods are connected to earth anchors that are placed within augured holes within the soil beyond the retaining wall.
Once assembled, the wall plate is installed, and the rod assembly is tightened. This can potentially straighten the wall and return it to its original position.
Helical anchors are installed from the exposed face of the retaining wall, through a hole cut in the wall. The anchor’s helical blades help to pull it deep into the soil and anchor it there. After closing the hole in the retaining wall, a wall plate is installed and a nut is tightened over the protruding threaded rod to brace the wall.
Wall anchors are generally the more economical solution to repairing a retaining wall. However, in some cases, wall anchor installation is not a possibility, and helical anchor installation must be considered.
This includes situations where rocky soil is an issue, or when space restrictions make auguring a hole beyond the retaining wall an impractical solution. Your foundation repair specialist will be able to advise you on the most appropriate solution for you.
