Don’t panic when concrete walls begin to disintegrate. Patch. Throughout a rainy Oregon winter, basement walls frequently experience peeling and collapsing. You may repair the wall by applying a bonding agent that allows fresh concrete to adhere to the old and then fixing the damaged area.
First, prepare the patching area. Using a tiny paint scraper, remove all loose debris, and then brush away the dust. You can utilize masonry or concrete repair mixes that are sold in home improvement stores, or you can purchase a bottle of concrete bonding agent and a bag of mortar. Allow the bonding agent to get tacky before applying it to the old concrete.
Mix the mortar or patching concrete with water until it has a peanut butter-like consistency. Smooth the surface using a trowel after applying the material. For substantial patchwork, you may need to further dilute the mortar to create slurry and apply it with a paintbrush.
After the patch has dried (typically a few days), apply a waterproofing solution or paint using a paintbrush. Check and alter gutters or install a French drain to deflect water away from the foundation as a precaution. — Homes & Gardens staff Sign up for OregonLive.com’s newsletters if you want to receive a daily homes and gardens tip automatically.

Why is my concrete wall falling apart?
Why Is Your Concrete Foundation Falling Apart? Your collapsing concrete foundation may be the result of a process known as scaling (or spalling). Scaling often occurs when your concrete foundation is exposed to freezing and thawing water, causing it to collapse or chip.
Scaling can also result from age or regular pressure washing or sandblasting of the foundation. Scaling may first appear to be a minor aesthetic issue, but if left addressed, it can develop into a structural concern. Frothing and Freezing Although it appears sturdy and lasting, concrete is permeable and will absorb water.
When this trapped water within the concrete freezes, it separates the cement binder. This expansion and the subsequent contraction caused by the refreezing of the water produces crumbling. If you reside in a region where winter temperatures are cold enough to freeze water, you should seal your concrete stairs or walkway once a year to prevent water from entering.
Minerals Gravel is required as an aggregate in concrete. When the stone used for this gravel includes certain mineral deposits, these minerals progressively leach out and cause concrete to fracture and crumble. This is mostly caused by pyrites in residential concrete. Other minerals, such as silica and mica, contribute to degradation when present in excessive quantities.
Modern testing procedures for concrete eliminate these issues in newly poured concrete, however older concrete structures may be prone to this problem. De-icing Frost-covered concrete driveways become slippery and hazardous to walk on when salted. A small amount of rock salt may facilitate melting and provide traction, but it will also harm the concrete’s surface.
- Due to a chemical reaction, rock salt, also known as sodium chloride, causes pitting and cracking on the surface of concrete.
- Using magnesium chloride or potassium chloride as alternate de-icing crystals prevents this from occurring.
- Excessive Water Concrete is available in dry form, either in bags of cement or already mixed with gravel.
Cement reacts chemically with moisture and begins to harden as soon as it is mixed with water. According to the Portland Cement Association, the chemical linkages that generate a strong and durable concrete surface will be weakened if too much water is added during the mixing process.
Why Reappear? – “I’ve also discovered that carrying a few bags of resurfacer in the truck might come in helpful when dealing with unanticipated concrete concerns on the job site that require immediate attention. It has helped me keep consumers satisfied on several occasions.” — Thomas Werline, seasoned builder, finisher, and mason By spreading a thin layer of pre-blended, polymer-modified flowable mortar over an existing surface, resurfacing is a proven approach for restoring the resilience and look of deteriorated concrete.
Compared to replacement, resurfacing concrete is substantially less costly. It costs between $3.50 and $5.00 per square foot to break up, carry away, and construct a new slab of concrete, but resurfacing concrete costs just approximately 25 cents per square foot. In addition, resurfacing requires less effort and is less disruptive than concrete replacement.
Ultimately, resurfacing can provide contractors with a large number of profitable concrete restoration contracts. Experience gained by contractors indicates that high-quality, well-formulated, and correctly applied resurfacers can increase the life of concrete by years.
Although a variety of elements, including adequate surface preparation and application (which will be discussed later), contribute to the effective restoration of concrete, resurfacing offers contractors a number of specific benefits. Resurfacers eliminate the time, effort, and cost associated with removing old concrete and pouring a new slab.
Resurfacing does not require any specific abilities or training. In one to two days, resurfaced concrete can be reopened to vehicle traffic. Resurfacers may be applied in a range of thicknesses, making them suitable for a number of restoration repair applications.
In addition to repair and restoration, resurfacers preserve concrete to reduce future maintenance. For extra aesthetic appeal, resurfaced concrete can be tinted, stamped, and/or stained. Thomas Werline of Orlando, Florida, a seasoned contractor, finisher, and mason, has resurfaced concrete on residential and commercial projects of all kinds from New Jersey to California over the past 45 years.
“Depending on the thickness of the material placed, resurfacing concrete is useful since it may be used to make small aesthetic modifications or extensive repairs. Using a concrete resurfacer such as that manufactured by QUIKRETE has been extremely advantageous to contractors like myself, particularly during the building slowdown 10 years ago “accordance with Werline
How does one conceal a deteriorating wall?
3:75 || RECIPIENT: – Media Platforms Design Team After months of spackling, sanding, and repainting, the hairline cracks in your living room wall are driving you insane. THE QUICK FIX First, gently enlarge the crack by scratching it with the can opener’s pointed end.
Foundation Cracks – Structural foundation cracks (cracks that weaken or potentially weaken the foundation) can be repaired as long as the structural integrity of the concrete is still intact and the stem walls have not rotated out of plumb. Nevertheless, (e.g.
Perimeter foundation cracks, basement wall cracks, etc.) may be signs of foundation collapse and, as such, should be addressed by a foundation repair professional such as Sinai Construction. This is especially true if the fissures are wider than a quarter inch. Neglecting warning signals when they first arise may result in more extensive damage, and hence much higher repair expenses.
The foundation and other structural parts meant to give structural integrity to the structure and resist seismic movement must be continuous in order to perform their intended function. Cracks are discontinuities in this continuity and hence potential locations of structural breakdown.
How do you repair a crumbling basement wall?
How to Select the Appropriate Basement Wall Repair Method frequently has leakage and seepage issues in the spring when snow and ice begin to melt, as well as throughout the year after heavy rainfall. Seepage occurs when groundwater slowly seeps through the pores of a wall and appears as a moist area or spots.
Leakage is the rapid passage of groundwater via joints and fissures in a pressured wall. Only when the foundation walls or surrounding soil are moist and the foundation has a weak area do these issues arise. After locating the source of the moisture, the problem can be remedied as follows: Repair and maintain your gutter, eaves trough system, and downspouts if roof runoff is the issue.
Ensure that the eaves trough discharges at least 3 feet (91.44 centimeters) away from the house and slopes away from the foundation. If window wells are collecting water, well covers should be installed. If there are gaps between the soil and the basement wall, fill them with a material such as pea gravel.
Depending on the amount of extra groundwater, you may need to install a sump pump to drain it. If there is significant leakage or pressure, you may need to add weep pipes to aid with drainage. If your walls are built of poured concrete, you should clean any cracks before repairing them using mortar, hydraulic cement, or polyurethane.
If your walls are formed of concrete blocks or the cracks are wider than half an inch (1.3 cm), plug the crevices using a mixture of sand and epoxy. Install a footing drainage system around the exterior of your basement walls if the problem is too severe for any of the preceding solutions.
The potential for damage is considerable and widespread. In a later stage, the wall has begun to lean inward and swell. This image was captured by an Acculevel project manager during a normal consultation for a free estimate.
Can a wall made of concrete be resurfaced?
Apply the Resurfacer – The resurfacer must be applied to a damp surface in order to prevent the concrete from absorbing moisture from the resurfacer while it cures. Just before mixing and applying the resurfacer, spray the slab with the hose to cool it and clear away any standing water.
- Pouring a little amount of concrete resurfacer onto the surface and immediately spreading it uniformly with a light, long-handled squeegee is the easiest way to apply it.
- The resurfacer can also be applied with a trowel or a brush.
- Work no more than approximately 144 square feet at a time.
- If at all feasible, divide your work so that each application reaches the margins of control and expansion joints.
If a second coat is required, allow the surface to dry for two to three hours before applying a second coat using the same process. The selection should be based on how successfully the first coat has concealed minor flaws.
