Water entering a basement through a foundation crack can be worrying. So can a crack that appears to be widening, a wall that seems to be bowing, or dampness that returns after every storm. One possible factor is hydrostatic pressure: the force groundwater exerts against a foundation when water builds up in the soil around it.
Hydrostatic pressure can contribute to water intrusion and stress on foundation walls, but it is not the only cause of cracks or leaks. The right repair depends on what is happening at the property—whether the issue is primarily water seepage, structural movement, or both.
Alpine Companies has helped Colorado property owners with foundation repair since 1963. Our team evaluates the crack, wall condition, and site factors to recommend a repair appropriate to the problem. In some cases, that may include structural epoxy injection. In others, addressing water management or considering a different repair method may be necessary.
What Is Hydrostatic Pressure?
Soil around a foundation can absorb water from rain, snowmelt, irrigation, or changing groundwater conditions. When water collects in the soil beside a basement wall, it can create pressure against that wall. This is called hydrostatic pressure.
The amount of pressure and its effect on a foundation depend on factors such as soil type, drainage, grading, groundwater conditions, and the wall’s construction and condition. Water pressure is not automatically the cause of every basement leak or foundation crack, but it is an important possibility to consider during an inspection.
How Can Water Build Up Around a Foundation in Colorado?
Several site conditions can allow soil near a foundation to stay wet or become saturated, including:
- Poor drainage or water that does not flow away from the foundation
- Downspouts that release water close to the home
- Ground that slopes toward the foundation
- Heavy or prolonged rain and seasonal snowmelt
- Irrigation that repeatedly saturates the soil near the foundation
- Soil conditions that retain water
- High water tables and fissures
- Underground Streams
- Missing or leaking window wells and improperly installed egress windows
Colorado properties vary widely. Expansive clay soils in some areas can change volume as their moisture content changes, while elevation, weather, drainage, and site conditions also affect how water behaves around a foundation. An on-site evaluation is needed to understand the conditions at a specific property.
Signs That Water or Pressure May Be Affecting a Basement Wall in Colorado
Possible signs include:
- Water entering through a visible crack or joint
- Damp areas, water stains, or recurring moisture on a basement wall
- White, powdery mineral deposits known as efflorescence
- Musty odors or repeated wet areas after rain or snowmelt
- Cracks that appear to change over time
- A wall that appears to be leaning, bowing, or moving
These signs do not identify the cause on their own. For example, a crack may be related to water entry, settlement, soil movement, construction conditions, or a combination of factors. A crack that is leaking is not necessarily structural, and a structural crack may not be actively leaking.
If a wall appears to be sinking, bowing, tilting or the crack is changing, arrange a professional evaluation from Alpine Companies rather than relying on a surface patch alone.
Why Patching the Visible Crack Is Typically Not Enough
A surface seal can sometimes hide the visible opening without addressing the full depth of a crack or the conditions that caused the problem. If water continues to collect against the wall, it may find another route into the basement. If the wall is moving, a cosmetic patch may not provide the structural repair needed.
That is why an effective repair starts with understanding the problem:
- Assess the crack and wall. Look at the crack’s location and pattern, the condition of the concrete, and any signs of movement.
- Consider water and site conditions. Review where water may be coming from and whether drainage, grading, or seasonal moisture could be contributing.
- Select a suitable repair. The repair should match the condition of the crack and wall—not just the visible symptom.
- Explain any additional work that may be needed. If water management or structural stabilization is also a concern, crack repair alone may not address the whole problem.
How Alpine Companies Has Been Evaluating Foundation Cracks For Over 60 Years In Colorado
Alpine Companies provides foundation repair, epoxy injection, chemical grouting and concrete restoration services in Colorado. Our team evaluates the property and the nature of the crack before recommending a repair. Where a project calls for engineering input, Alpine’s in-house structural engineering capabilities help inform the repair plan.
The evaluation considers whether the crack appears suitable for epoxy injection, whether there are signs of ongoing movement, and whether water-related conditions need to be addressed as part of the solution. The goal is to select a repair based on the condition of the foundation—not to recommend epoxy injection for every crack.
When Structural Epoxy Injection May Be Appropriate
Structural epoxy injection is designed to bond suitable cracks in concrete. Using (LV) Low Viscosity or (SLV) Super Low Viscosity low-pressure process, a qualified crew injects epoxy into the crack so it can penetrate and cure within the concrete. When the crack and surrounding concrete are appropriate for this method, the cured material can restore a structural bond across the crack.
Epoxy injection may be considered when a crack requires structural bonding and the conditions allow the material to be installed correctly. It is not a universal solution for every leaking or moving foundation wall. For example, an epoxy injection repair does not by itself relieve hydrostatic pressure, correct a drainage problem, or stabilize every wall that is bowing or shifting.
The condition of the crack, moisture in the concrete, active water flow, and the cause of movement can all influence the repair plan. If water is actively entering the crack, the repair may require a different material, additional preparation, or a separate water-control approach. Alpine can evaluate those conditions and explain which options are appropriate.

Water Management and Structural Repair Address Different Problems
It is important to distinguish between (controlling water) and (repairing concrete).
- A structural crack repair is intended to address the crack and, when appropriate, restore a bond in the concrete.
- Water-management work is intended to reduce or redirect water around the foundation.
- Some properties need one type of work; others may need a combination, depending on the source of the water and the condition of the wall.
A successful plan should account for both the visible damage and its likely contributing conditions. Alpine’s inspection can help determine whether structural epoxy injection is suitable and whether other measures should also be considered.

Frequently Asked Questions
Does hydrostatic pressure always cause foundation cracks?
No. Hydrostatic pressure can contribute to stress on a foundation wall, but cracks may also result from settlement, soil movement, construction conditions, or other causes. An inspection is needed to assess the likely source.
Can epoxy injection stop a basement leak?
Epoxy injection can seal and structurally bond certain suitable cracks. Whether it is the right choice for a leaking crack depends on the crack, wall, and water conditions. It does not by itself correct the source of groundwater pressure or a drainage problem.
Is every leaking foundation crack structural?
No. Some cracks allow water entry without indicating significant structural movement; others may be associated with movement or damage. A professional assessment can help distinguish between them.
What if water is actively flowing through a crack?
Active water can affect which repair materials and methods are appropriate. The crack and surrounding conditions should be evaluated before choosing a repair. In some situations, water control or a different injection approach may be needed.
Should I be concerned if my basement wall is bowing?
A wall that appears to be bowing, leaning, or changing should be evaluated by a qualified foundation professional. Do not assume that injecting the visible crack alone will resolve the wall movement.
Does Alpine inject every foundation crack with epoxy?
No. Epoxy injection is appropriate for certain cracks, but the right repair depends on the concrete, the crack, water conditions, and any signs of movement. Alpine evaluates those factors before recommending a repair.
