Mudjacking / Slabjacking in Troy, NC

Mudjacking and Slabjacking are non-invasive methods used to raise and stabilize sunken concrete slabs. This process involves injecting a slurry mixture or expanding foam beneath the slab, which fills voids and gently lifts the concrete back to its original position.

Common Causes of Sunken Concrete

• Soil Erosion and Settlement – Water washes away supporting soil, causing slabs to sink or crack.
• Poor Compaction During Construction – Weak soil beneath the slab settles over time, leading to uneven concrete.
• Heavy Loads and Traffic – Excessive weight from vehicles or heavy equipment accelerates slab sinking.
• Water Accumulation and Drainage Issues – Poor drainage creates voids under the slab, causing it to sink.
• Tree Root Growth – Expanding roots disrupt the soil beneath concrete, leading to uneven surfaces.

Mudjacking and Slabjacking Methods We Use

• Traditional Mudjacking – A cement-based slurry is pumped beneath sunken slabs to lift and level them.
• Polyurethane Foam Injection (Polyjacking) – Expanding foam is injected to raise concrete without adding excess weight.
• Void Filling – Soil gaps under the slab are filled to prevent future sinking.
• Concrete Resurfacing and Sealing – Once lifted, slabs are sealed to prevent further deterioration.
