Pavement and Slab Settlement

Raise and stabilize sunken pavement slabs without major excavation or slab demolition.

Engineering overview

Causes of Ground Distress

Backfill under slabs suffers from inadequate compaction and is disturbed repeatedly by long-term dynamic vehicle loads.

Rainwater seeps under slabs, erodes bedding soil and creates voids, leaving slabs without support.

What to assess

Typical Performance

Sinking of concrete slabs

Slab displacement and warping

Panel cracking and broken slabs

Voids and hollowing under slabs

Pumping and mud ejection on pavement

Damaged and leaking joints

Staged injection · real-time measurement

Our approach

How Hengxiang Hongye Performs Remediation

Through our non-destructive and controllable patented technology, the weak soil layer of the holding layer is consolidated as a whole, and the consolidated and reinforced foundation soil forms a composite foundation, whose bearing capacity value can reach nearly three times of the original bearing capacity, and well support the upper load.

01
Drilling
Bore holes in the affected area with a diameter of 6–10 mm.
02
Injection
Inject a specialized inorganic material.
03
Solidification
The material rapidly solidifies with soil, filling voids and stabilizing the ground.
04
Re-balancing
Lift and reinforce the foundation until re-leveling is achieved.
