Cracks in Your Foundation?
Don’t Wait to Fix Them.
Even a hairline crack in your foundation can let in water, increase humidity, or weaken structural integrity over time. At Montana Basement Solutions, we specialize in professional foundation crack repair that not only seals the damage but protects the structural integrity of your home for years to come.
Whether you’re seeing visible cracking, water intrusion, or signs of settling, our team will diagnose the cause and deliver a permanent, non-invasive fix—often without the need for excavation.
Why Foundation Cracks Happen in Montana
Foundations in Montana face unique challenges. Shifting soil, clay expansion, seasonal freeze/thaw cycles, and groundwater pressure can all lead to cracks—even in newer homes.
Common causes include:
- Hydrostatic pressure (water pushing against the wall from the outside)
- Poor soil compaction
- Inadequate drainage or grading
- Aging or drying concrete
- Frost heave and seasonal ground movement
Some cracks are purely cosmetic—but many are not. We help you identify the difference and address the real cause.
Types of Cracks We Repair
Vertical or Diagonal Wall Cracks
Cracks Near Windows, Doors, or Pipe Penetrations
Horizontal Cracks (Often More Serious)
Hairline Cracks With Water Staining or Efflorescence
Floor Cracks or Slab Separation
Cracks in Block, Poured Concrete, or Stone Foundations
We also inspect and treat cracks found in crawlspace walls, garage slabs, and daylight basements.
Our Foundation Crack Repair Methods
Flexible Polyurethane Injection
For active water intrusion or recurring leaks, we use a hydrophobic polyurethane foam that expands deep into the crack and creates a permanent, flexible seal—even if the foundation continues to shift slightly over time.
- Seals the entire depth of the wall
- Water-activated foam expands to fill voids
- Bonds to wet or dry surfaces
- Remains flexible to resist future cracking
This method is ideal for poured concrete walls and is typically completed from the inside—no excavation required.
Epoxy Injection
For structural cracks (those that compromise the integrity of the foundation), we use epoxy resins that cure to a rigid, high-strength bond. These are applied under pressure to fully seal the crack and restore original strength.
- Structural-grade bonding
- Best for load-bearing cracks
- Can be painted or finished after curing
Our team will assess whether your crack requires structural or non-structural repair during your initial inspection.
Exterior Waterproofing Add-Ons
In some cases—especially for larger or multiple cracks—we may recommend exterior waterproofing upgrades like:
- Wall waterproofing membranes
- French drains or grading adjustments
- Foundation coatings or sealants
- Sump pump installation
We always start with the most efficient, least invasive repair method—but we’ll never skip steps if your home needs more protection.
When to Repair Foundation Cracks
You should schedule an inspection if you notice:
- Water seepage through cracks
- Cold drafts or damp smells from foundation walls
- Mold growth or increased humidity
- Wall bowing, uneven floors, or shifting door frames
- Cracks growing over time or showing new patterns
The sooner we address the issue, the less likely you’ll face more costly repairs—or damage to your belongings.
