Concrete Bearing Surface Injection

Concrete Bearing Surface Structural Injection

In heavy civil engineering and industrial construction, the bearing surface is the most critical point for load transfer. Bearing Surface Injection is utilized to treat honeycombing, segregation, or voids that occur at the interface between structural elements. EG Core employs high-strength, low-viscosity resins to restore 100% surface contact, ensuring that structural loads are distributed exactly as the engineers intended.

Restoring the Structural Load Path

Even microscopic voids beneath a bearing plate or column base can lead to stress concentrations, causing localized concrete crushing or eccentric loading. Our Epoxy Injection process uses pressure-controlled pumps to permeate the concrete matrix and fill all internal cavities. This restores the full load-bearing capacity of the element without the need for costly demolition or structural replacement.

Technical Performance Specs

  • Typical Scenarios: Bridge bearing seats, machine bases, and column footings.
  • Resin Systems: High-modulus, non-shrink structural epoxies.
  • Key Benefit: Full-load transfer restoration with superior compressive strength.
  • Target: Elimination of point-loading and seismic joint stabilization.

Precision Leveling & Grouting

For large-scale infrastructure and industrial machinery, precise leveling is non-negotiable. We provide structural grouting that remains dimensionally stable under dynamic loads. By injecting high-performance resins into the shim space, we create a permanent, vibration-dampening support that protects both the machinery and the underlying concrete foundation from premature fatigue.
