Void Filling in Hobbs, NM

Void filling is a critical process used to stabilize and reinforce the ground beneath concrete slabs, driveways, foundations, and other structures. Over time, erosion, soil movement, and underground water flow can create empty spaces (voids) under concrete, leading to cracks, sinking, and structural instability.

At Hobbs Foundation Repair, we specialize in advanced void-filling techniques to ensure that your home or commercial property remains safe, stable, and properly supported.

Why Void Filling is Necessary

Voids beneath a foundation or concrete slab can cause significant damage if not addressed in time. Some key reasons why void filling is essential include:

• Prevents Foundation Settlement – Filling voids helps support sinking structures.
• Eliminates Uneven & Sunken Concrete – Stops further slab sinking and cracking.
• Reduces Soil Erosion & Washout Issues – Stabilizes weak ground conditions.
• Enhances Load-Bearing Capacity – Strengthens soil to support heavy structures.
• Prevents Water Damage & Moisture Intrusion – Reduces the risk of mold and foundation deterioration.

Common Causes of Voids Under Foundations

Voids can form due to a variety of environmental and structural factors:

• Soil Erosion from Poor Drainage – Water washes away supporting soil, leaving empty spaces.
• Expansive Soil Movement – Texas soil expands when wet and contracts when dry, causing shifting.
• Plumbing Leaks Beneath the Slab – Water leaks weaken soil and create sinkholes.
• Heavy Rain & Flooding – Excess moisture leads to soil displacement.
• Improper Soil Compaction During Construction – Loose soil beneath a structure can lead to settlement over time.

Signs You Need Void Filling

If you notice any of the following warning signs, void filling may be necessary:

• Uneven or Sunken Concrete – Driveways, patios, or foundations appear lower in certain areas.
• Cracks in Walls, Floors, or Slabs – A sign of movement due to voids underneath.
• Gaps Between the Ground & Concrete Structures – Indicates settling due to missing support.
• Frequent Water Pooling Around Your Home – Can lead to soil erosion and void formation.
• Foundation Heaving or Sinking – Visible movement of concrete or foundation elements.

Our Void Filling Techniques

We use advanced void-filling solutions to stabilize and reinforce foundations, slabs, and driveways:

1. Polyurethane Foam Injection

• Expands to Fill Voids & Lift Concrete – Lightweight yet highly durable.
• Fast-Acting & Long-Lasting – Hardens within minutes and supports heavy loads.
• Waterproof & Moisture-Resistant – Prevents further soil erosion.

2. Mudjacking & Slabjacking

• Cement-Based Slurry Injection – Fills voids and lifts sunken concrete.
• Cost-Effective & Efficient – Ideal for driveways, patios, and sidewalks.
• Restores Stability Without Full Replacement – Avoids the expense of new concrete pouring.

3. Compaction Grouting

• Strengthens Weak or Loose Soil – Prevents future void formation.
• Deep Injection for Maximum Stabilization – Fills underground gaps effectively.

4. Soil Stabilization & Void Prevention

• Prevents Further Settlement – Reinforces ground conditions for long-term protection.
• Chemical Soil Injection for Added Strength – Hardens weak soil and stops erosion.
