Basement Wall Caving In

If you notice your basement walls are bent, bowed, leaning, or they look like they’re caving in, they should be repaired right away to prevent water damage and other structural issues. These walls represent the foundation of your home, so if they start to lean or bend, the structure of your home could be at risk.

Complete Fix For A Basement Wall That Is Caving In

Carbon Fiber Staples

This is only a short-term solution, and does not repair completely a basement wall caving in issue.

Cracked walls that are repaired with only injected material may suffer from long-term creep and fatigue causing failure over time due to foundation movement. By cross-stitching concrete crack repairs with staples, this creep is eliminated and the long-term performance of the repair material improves.

The staples are made of high-tensile-strength carbon fibers encapsulated in a thermal-set resin and cured under pressure during manufacturing. A peel-ply fabric is adhered to the staples, and when removed, it leaves a prepared bonding surface ready for adhesion to a prepared substrate. A manual vacuum lamination process ensures a void-free bond of the staples on severely deflected walls. The typical staple is 10 inches long by 0.38-inch wide, with 1-inch legs. The staples can be used with various crack repair materials, including carbon fiber straps, and add little additional cost to the entire crack repair.

To make sure your basement walls have the support they need to keep water at bay, we’ll install carbon-fiber kevlar straps with incredibly rigid epoxies. These heavy-duty straps cling to the walls, giving them stronger-than-steel strength. This straightens the walls in your basement, repairing cracks in the foundation. Once we install the straps over the walls, the materials will harden and become flush with the rest of your basement to create a securely bonded structure. This creates a grid-like pattern with the bricks or concrete in your basement running horizontal and the straps running vertically. We can even paint over the straps once they’re dry to ensure that your walls look seamless.


To prevent soil expansion and excess water from pushing against the walls of your basement, we will also install heavy-duty tie-backs, or long, screw-like shafts, to keep your walls in place. We install these tie-backs at an angle for more lateral stability to keep your walls from bending, leaning, or cracking in the future. For more protection, we can also install wall anchors comprised of metal plates and a steel shaft. These anchors stabilize leaning or bowed walls. They require minimal excavation, so you don’t have to worry about our team ruining your yard or your home’s landscaping.

This technique then restores the integrity of the wall structures and overall foundation of your home hence ensuring a lasting and secure home. To ensure the walls remain upright standing at all times, we fit long-lasting tie-backs or metal shafts to keep your walls intact.

This then enhances the wall stability. Steel shaft anchors can also play a similar role in preventing walls from bending, leaning, or cracking for the foreseeable future. Once you apply this particular fix, you should never have to worry about soil expansion and excess water pushing your vault walls.


Causes For A Basement Wall To Cave In

Over time, soil and excess water will push against the walls of your basement, forcing them to bow, bend, crack, or eventually cave in.

Soil Expansion –

As the soil absorbs water it becomes saturated. To the point beyond which the soil particles become loose forcing it to expand and push against the wall foundation. This pressure is too much for your walls that they begin to buckle to the pressure of the soil. 

Typically, bowed, bent, or crumbling basement walls are caused by soil expansion. Water and other changes to the soil around your home can put added pressure on the walls of your basement. These walls are designed to support the downward weight of your home, but not lateral pressure due to soil expansion.

Rainwater –

Excessive rainwater seeping through your structural foundation especially due to cracks or gaps in the wall may result in excessive saturation, which in turn weakens by enlarging the said gaps. When the gaps are big enough water will get into your basement.

Improper Drainage

– This occurs due to a poor drainage system in your home originating from say, a plumbing failure. When such excess water cannot find its course, it gradually drips down your vault walls, essentially dampening and weakening the wall structure.

Consequences Of A Basement Wall Caving In

Foundational Failure –

The soil around your foundation absorbing excessive water may in essence affect the overall stability and strength of such a foundation. In the long run, your home could be in danger of collapse or chronic structural damage towards your basement walls.

Once water gets into your home, it will lead to lasting structural damage that will make your home less safe. The walls will continue to cave in, and part of your home could even collapse. This will lower the overall value of your home. If you’re planning on selling your home, you will have to lower the price as the home inspector brings these issues to your attention.

Cracked Walls

– Excessive water forcing its way down the vault through its walls may subsequently expand any tiny gaps in the wall, thus leaving behind a trail of more cracks. Such cracks are bound to accentuate the effects of overall structural damage.

Basement Flooding

– This may happen to unsuspecting homeowners who do not regularly assess the safety of their cellars. Over time, percolating water may find its rest on your vault floor and gradually rise to flooding levels. This may damage any personal belongings stored in the cellar.

As soil and water continue to push against the walls of your basement, the foundation of your home will become less secure. Water will start to leak through the holes or gaps in the walls, leading to water damage and the spread of mold.

As water and moisture spread, mold can collect in your family’s basement, which poses a danger to you and your loved ones’ health. Mold can lead to respiratory issues, skin and eye irritation, intense coughing, and other health issues

Preventing Having A Wall Caving In

my suggestion is to avoid having a wall caving in as a plan for the future. Have your typical four inch gutters replaced with six inch gutters and make sure that the ground around the house is regraded properly to minimize any excess water reaching the wall.

Furthermore, when you do a foundation inspection, ensure that a checking if the basement wall is caving in or buckling is included in the checklist thereof.

Recommended Articles

We have some articles that I would like to recommend to the readers.

Foundation Repair And Maintenance

We have described here the type of foundations, what is a foundation inspection and what should be included in a good foundation inspection checklist. We can discover problems in the foundation to make us ask ourselves if it is safe to live in a house with foundation problems, and what entails a foundation repair. Not only the repair activity itself but how it affects our wallets.

I explain if the foundation repair is actually covered by homeowners insurance and the actual foundation repair cost. We disaggregated these foundation repair costs and determined, the cost per pier when footings or piers are the solutions for the settlement of a foundation.

To repair a foundation, the service provider might require an underpinning system using piers: push piers vs helical piers where helical piers are preferable for residential real estate objects, despite their costs. Also when you compare helical piers with concrete footings, we can determine that helical piers are more cost-efficient than concrete footings, in my opinion.

We have water in the crawlspace, which can be an issue for the whole foundation if the problem persists, and an additional difficulty when selling a house with water in the crawl space, as it can provide the prospective buyer with a lot of bargaining power, so what can we do: I explain what to do when the crawlspace is flooded or there are simply puddles of water always standing, thus I describe how to remove quickly the water in the crawlspace and how to prevent the problem for the future. So I discuss if it is normal to have water in the crawlspace after a heavy rain, and the importance to perform a crawlspace waterproofing thereafter, normally by installing a vapor barrier.

I describe how to improve the air quality in the crawlspace and to accomplish this, I am reluctant to use lime powder in this article, where I explain the pros and cons, as I would be using lime powder only to avoid the dangers of raw sewage under the house.

We discuss the sill plate replacement cost and how to avoid the outdoor sump pump freezing because it happened to me once.

There are always new methods for repairing foundations. One of them that we investigate here is the Powerbrace foundation repair method.

Animals can be a problem when they live near the foundation: In the following articles, we describe how to remove them and how to prevent them from digging and burrowing. The articles are about animals digging holes around the foundation or when they are burrowing below concrete, below a concrete slab, or between gaps in concrete footings, for example.

In regards to basements, I describe how to solve the hydrostatic pressure in the basement, which is a lateral pressure that is the main cause for having a basement wall that is bowing, or that can be caving in or buckling. While a slight inward curve for basement wall bowing is acceptable, after that degree, you have to address the issue and face sometimes relatively high basement wall repair costs.

I provide to you some reasons why we will need a certified specialist to deal with a risky sewage backup in the basement because bacteria survive a long time in a contaminated sewage network, and also we discuss how to deal with a basement drain backing up in general and what to do when it happens only when flushing the toilet, something that is not a DYI project at all.


I explain here the process of concrete lifting or concrete raising, which can be done through mudjacking or slabjacking. We recommend the latter, which injects polyurethane foam.


There are some interesting articles here, in this Framing category. I refer to sistering floor joists, as a methodology to reinforce existing floor joists with some emphasis on sistering 2x6 floor joists or sistering with 2x8 instead, and about the building code for sistering joists, for sistering rafters, and the code for notching floor joists.

Many of these problems have a consequence: sinking or sagging floors.

Water Heaters

About water heaters, we have a complete guide about water heater types and their installation requirements, about power vent water heaters, and venting in tankless devices, and I also explain in detail the difference between a mobile home water heater and a standard water heater. I also describe in detail how to remove the heating element without an element wrench using just a socket, and how to fix leaks.

We have a few reviews when a water heater falls into our hands, such as the Titan product portfolio, Navien lineup, the Titan N-160 reviews, the most praised by our readers, and the Rinnai R94LSi.

I study several water heater capacities and tested 20-gallon water heater units and a comparison between point of use and tankless water heaters.

We open a tankless water heater to show how does it look like inside a tankless water heater, and how to protect your water heater against the effects of hard water. I also explain the pros and cons of tankless water heaters because many people consider that tankless units are better than standard heaters and it is not always the case.

After the lifecycle of the water heater is over, I reveal to you different options to proceed with its disposal.


Just because they became popular and related to current news, I study how to identify aluminum wiring and once discovered, how to proceed with its remediation or retrofit.

Pest Control

I have a featured article where I compare Orkin vs Terminix pest control services.
