Basement Crack Injection in Round Rock, TX
Cracks in your basement walls or floors may start small, but here in Round Rock’s shifting clay soil, they can quickly turn into major water leaks and structural problems. When moisture starts seeping through concrete, it leads to mold, damage to stored items, weakens the foundation, and can even cause your basement to feel damp and uncomfortable.
At Round Rock Foundation Repair Group, we provide professional basement crack injection services to permanently seal cracks, stop leaks, and restore the integrity of your foundation. Whether you’re dealing with moisture seepage, a leaking basement wall, or long cracks spreading across concrete, our injection methods offer a reliable and long-lasting fix.
Why Basement Cracks Form in Round Rock
Expansive Clay Soil Movement
The soil around Round Rock expands when wet and shrinks during dry spells, putting pressure on basement walls and floors. This movement commonly causes cracks, especially near joints or corners.
Poor Drainage Around the Foundation
Water pooling near the home can force moisture into cracks, leading to basement leak repair needs or foundation water leak repair.
Hydrostatic Pressure
Water buildup in the soil pushes against the basement walls, creating cracks or enlarging existing ones.
Age and Wear
Older homes naturally develop concrete cracks over time, especially if waterproofing was never done.
Construction Weak Points
Improper foundation installation or lack of reinforcement can leave weak areas that crack under pressure.
Signs You Need Basement Crack Injection
Water Leaking Through Cracks
If water enters during rain, the crack has penetrated the wall completely.
Damp or Musty Smells
Moisture entering through cracks often causes odors and mold.
Vertical or Diagonal Wall Cracks
These typically indicate settling, often requiring sealing foundation cracks or foundation inspection and repair.
Efflorescence (White Powdery Stains)
A sign that water is moving through the concrete and leaving mineral deposits behind.
Floor Cracks Spreading Across the Basement
These are often corrected with basement floor crack repair and injection techniques.
If you notice any of these issues, the sooner you act, the easier the repair.
Our Basement Crack Injection Process

Inspection and Moisture Source Evaluation
Our team begins with a thorough inspection to determine:
Crack depth and pattern
Whether the crack is structural or surface-level

Understanding the cause helps us create a long-lasting repair plan.
Polyurethane and Epoxy Injection Options
Depending on the type of crack, we’ll choose the best injection material.
Polyurethane Foundation Crack Repair
Polyurethane expands inside the crack, forming a flexible, waterproof seal. This is ideal for active leaks or cracks exposed to water.
Epoxy Foundation Crack Repair
Epoxy is used for structural cracks because it bonds the concrete back together, restoring strength. It’s perfect for deeper or wider cracks.
How Injection Works
Ports are placed along the crack.
Material is injected under controlled pressure.
Resin fills the entire crack from inside the wall or floor.
The material cures, creating a solid waterproof seal.
Injection repairs the crack from the inside out, ensuring long-term protection.
Finishing and Protection
After the crack is sealed, we reinforce the area to prevent future issues.
Wall Surface Sealing
We apply protective coatings to keep humidity and moisture out of the concrete.
Carbon Fiber Wall Reinforcement (If Needed)
For walls showing bowing or stress, we install carbon fiber straps to stabilize and strengthen the wall.
Improving Drainage
If poor drainage is causing repeated leaks, we can provide foundation drain repair or grading improvements.
