What Causes Foundation Damage?

Your home is only as stable as its foundation. Changing soil conditions, age, or improperly compressed soils often result in uneven distribution of weight leading to significant structural damage.

Water Retention / Hydrostatic Pressure:

All soil can expand and contract after a heavy rain or drought. When the soil supporting your foundation changes, it can cause your home to shift. During wet weather, water saturates surrounding soil, causing it to swell and push against subterranean walls. This lateral pressure can make basement walls bulge or leak, causing a wet and smelly basement.

Erosion / Washout:

As water flows through soil, it can cause the earth beneath or around your home to erode, leaving your foundation on less stable ground.

Plumbing Leaks or Improper Drainage:

Even a small crack in underground plumbing can lead to a massive amount of water retention in soil near your home. Poor drainage traps rainfall or underground water in surrounding soil causing substantial pressure against foundation walls.

Poorly Compacted Soil:

If a pre-construction site isn't correctly prepared, the soil can compress under the weight of the structure and cause an unstable foundation.

Bowed/Cracked Basement Walls

Basement walls are designed to support the downward weight of your home. Unfortunately, these walls are not intended to resist significant lateral pressure produced by expansive soil. Over time, this pressure can cause the horizontal seam between rows of concrete clock to bulge - resulting in bowing or cracking walls. Since basement walls are integral to a stuctures's stability, a damaged wall can cause serious issues for your foundation and greatly decrease your home's value.

What causes bowed walls?

  • Vertical columns of block are usually staggered, creating a strong and cohesive set of columns. Due to this staggering, cracking rarely runs up and down a basement wall.
  • Horizontal rows of block run in perfect rows, creating a weakness to exterior pressure. This is why subterranean block walls frequently crack horizontally.
An example of how external pressure can bow a basement wall.

How Do I Fix It?

Acculevel offers a variety of solutions for bowing or cracked basement walls. From carbon fiber straps to helical tiebacks or wall anchors. Acculevel has a solution that will best fit your specific problem.

Carbon Fiber Straps

Acculevel uses carbon-fiber kevlar straps in combination with incredibly rigid epoxies to reinforce basement walls with stronger-than-steel strength. These epoxies are designed to bond the carbon fiber straps directly to the structure by permeating both the foundation and carbon-fiber. After application, both materials harden into a permanently bonded structure.

This combination of bricks in staggered columns and strap-reinforced rows creates a strong "grid" ideal for combating exterior soil pressure. The repaired basement wall can also be painted leaving an almost invisible repair.

Sagging Floors

Are you noticing furniture leaning toward the center of the room, or do your floors have excessive bounce? Most sagging floors can be fixed relatively inexpensively. Acculevel can evaluate if you would benefit from our permanent floor support system.

Acculevel provides expert solutions for sagging floors

How Do I Fix It?

Acculevel can repair your sagging floors with structural supports that are installed with minimal invasion and cost.

Structural Supports

Metal beams supported with adjustable steel posts offer an easy, cost-effective solution in a crawl space. After installation, the system can be tightened and adjusted appropriately to secure, support, and sometimes lift the floor above.

Mid-span Support Jacks

Mid-span crawl space support jacks transfer the load of a house from the original weak or overloaded beams to metal beams. Steel is our first choice because it’s more durable, stronger, cleaner, and faster to install than concrete beams. Acculevel uses 6” I-Beams and a 18”x18” pre-cast footing. Most competitors rely on a much smaller 8”x8” footing and 4” I-Beams. We use the very best materials to ensure a longer lasting repair and the best distribution of weight possible. Additionally, they’re fully compatible with a crawl space encapsulation system.

Support & Joist Repair

Crawl space floor support and floor joist repair costs vary greatly depending on the size of the structure and location of trouble areas.

Foundation Repair Solutions

Helical Piers

Helical piers are long, screw-like shafts that can be drilled down to deep, stable soil. By leveraging the resulting resistance, the piers lift your foundation to a level state using heavy duty brackets.


Tie-backs are also long, screw-like shafts just like those used in helical pier installations. When installed at an angle instead of straight down, they can provide lateral stability to basement or retaining walls.

Wall Anchors

Wall anchors are comprised of metal plates and a steel shaft. These anchors provide supplemental lateral force to stabilize bowed and cracked walls. This installation is quick and requires minimal excavation or disturbance to the surrounding landscaping.

Carbon Fiber Straps

We combine carbon-fiber kevlar straps with incredibly rigid epoxies to reinforce basement walls with stronger than steel strength. These epoxies are designed to bond the carbon fiber straps directly to the structure by permeating both the foundation and carbon fiber.
