Engineering overview

Causes of Ground Distress

Groundwater seepage continuously scours soil particles, washing away fine grains and gradually forming cavities inside the soil.

Pipeline leakage and poor drainage aggravate soil erosion, and collapse occurs under superimposed loads.

What to assess

Typical Performance

Local collapse pits on ground surface

Hollowing and voiding of subsurface soil

Sudden sinkholes on pavements

Scour and loss of slope soil

Collapse of boundary and retaining walls

Voids beneath structures

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.
