Backfill Compaction Deficiency

Inadequate backfill compaction is one of the leading causes of foundation problems in U.S. commercial and industrial buildings. Many projects are built on graded fill areas or old landfill sites. Non-uniform fill, excessive lift thickness or poor compaction leads to long-term consolidation. When water infiltrates, pore pressure dissipates and soil volume continues to shrink, causing floor settlement, wall cracking and differential foundation movement, with high repair costs and liability risks.

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.
