Slab Lifting

Preventing Liabilities and Damage with Polyurethane Slab Lifting



Damaged slabs and structures pose serious liability risks and often signal further damage if left unattended. The good news is that these issues can be efficiently resolved using Polyurethane resin. Under ideal conditions, slabs and structures can be lifted within 1/8” of their original level. Compared to demolishing or replacing the slab, Polyurethane slab lifting is a more efficient and cost-effective solution.

Concrete Slab Lifting


Concrete slabs, known for their durability, are not immune to damage. If you notice sinking or cracked concrete in your residential, commercial, or industrial property, call Green Line Services right away. 


Causes of Sinking Concrete


Several factors can lead to concrete damage, including:


  • Erosion: Poor drainage, leaks in drain pipes, damaged water lines, and improperly placed downspouts can cause erosion.
  • Water Damage: Concrete is porous and can absorb water, leading to a settling foundation.
  • Heavy Loads: Excessive weight on concrete can cause it to shrink.
  • Poor Compaction: Improperly compacted backfill can result in sinking concrete.
  • Void Spaces: Empty spaces in the soil beneath concrete can lead to cracking and caving.
  • Biological Decay: Slabs built over biodegradable materials can sink as these materials deteriorate.


Damaged or uneven concrete not only causes property and equipment damage but can also lead to sinkholes, personal injury, and lawsuits. While full replacement is often considered, it is messy, expensive, and environmentally unfriendly. Mud jacking, though less costly than replacement, is also messy and not a permanent solution, as the mud can wash out completely.


Expert Slab Lifting in Houston, TX


Subsidence is a rampant problem in Texas, especially in Houston, where high rates of sinking ground increase the risk of floods. This can cause water to penetrate the subsurface, weaken the soil, and lead to uneven surfaces, concrete cracks, and foundation issues.

Polylifting, also known as polyjacking, is cleaner, more durable, and less costly than mud jacking or full slab replacement.
