Denver Area Foundation Or Slab Heaving (Upheaval)

Foundation upheaval can lift an entire structure, but more often it forces parts of a foundation or slab upwards, while other sections remain stationary. Either way, the damage that results will require the expertise of a foundation repair specialist

The Problem:

Your foundation or slab floor is moving upwards, leading to cracks in the walls and floors of your home.

Telltale Signs:

How to Fix It:

Unwanted water accumulating in the soil under your home - and the pressure it brings -- is typically the cause of slab and foundation heave. Peak Structural, INC.'s first priority will be to eliminate water sources wherever possible. We will check for underground water line leaks, clogged drains, broken sprinkler lines, as well as faulty gutter and leader systems. Once we have fixed water problems, we can begin making repairs.

Other causes for heaving include tree roots and pressure from adjacent buildings. Regardless of the cause, a certified foundation contractor is the best person to evaluate foundation heaving problems and suggest suitable solutions for your home.

What Causes Foundation Upheaval?

Heave is the upward movement of a foundation or slab caused by underlying soils that expand or swell. This occurs due to an increase in moisture or by freezing forces. Heave is more common with slabs than foundations because slabs have less weight to resist heaving forces. Unless there is a long period of drought, heave most commonly occurs within the first few years of the building's construction.

Slab and foundation heave are most commonly caused by these four forces:

Expansive Soils

A house built on soils with high clay content will be susceptible to heaving forces because clay-rich soil expands significantly when it gets wet.

The excavation for a foundation often gives the soil around and under a house a chance to dry out and shrink, as shown in the photo at right. After the house is built, clay-rich soil that gets soaked during wet spells can cause heaving problems, while also damaging foundation walls.

Frost Heave

Water increases about 9% in volume when it freezes. Wet soil can expand by at least that amount upon freezing. When this happens, the resulting pressure on a slab or foundation can cause it to shift and crack.

The colder the temperature, the deeper the soil will freeze. In frigid temperatures, foundations that were not built below the "frost" or freezing line can experience frost heave.

Frost forces can lift a foundation upwards dramatically, sometimes by several inches or more, leading to serious frost heaving damage. to a foundation.

Plumbing Leaks

Leaks in plumbing lines that run underneath a concrete slab or through a foundation wall can deposit moisture underneath the foundation and slab. This moisture can be from supply lines, waste lines, or even HVAC systems.

Over time, this moisture can cause the soils underneath the foundation to expand, which will then cause them to push up on the structure above.

Prolonged Or Heavy Precipitation

Too much precipitation combined with too little drainage away from the house will lead to increased moisture underneath your foundation. Moisture that comes into contact with expansive soil can result in heaving of your foundation and slabs.

Precipitation can also cause expansion in the soils on the sides of your foundation, leading to bowing, buckling walls.

What NOT To Do:

Cracks on floor slabs that are caused by foundation heave are unique in appearance.

You will see multiple cracks that come together to a point or form an enclosed loop where the heave is greatest.

Before doing any repairs to your foundation, it's important to identify the problem as heaving.

Some contractors who have not been fully educated on the signs of heave can easily misread the cracks in your home and suggest the wrong solution.

The problem? While heave is the opposite of foundation settlement, the symptoms are often similar. To an untrained eye, it may appear that the exterior walls are going down -- – when what’s really happening is that the basement slab is being pushed up near the center of the house.

To apply the right solution to a foundation problem, make sure you’re getting the right diagnosis.
