Services
Compaction Grouting
Compaction Grouting injects low-slump grout into loose soils to increase bearing capacity. This technique effectively addresses sinkhole remediation and foundation settlement issues through controlled soil densification. Our proprietary injection process minimizes fracturing risks while maximizing soil compaction efficiency.
Micropiles
Micropiles provide deep foundation support in challenging access conditions. Our installation process combines steel casing and high-strength grout to create load-bearing elements for unstable soils. This solution works particularly well in sinkhole-prone areas when combined with compaction grouting.
Slabjacking
Slabjacking restores sunken concrete surfaces through strategic grout injection. This cost-effective alternative to concrete replacement lifts slabs back to original grade with minimal disruption. Our precision drilling and pressure control ensure even lifting across affected areas.
Soil Nail Walls
Soil nail walls reinforce slopes and excavations using grouted steel elements. Our top-down construction method provides immediate stabilization for retaining walls and foundation excavations. This technique maintains structural integrity while minimizing ground disturbance.
Mobile Grout Plant
Our mobile grout plant batches materials on-site for optimal consistency control. This system eliminates delivery delays and material waste associated with pre-mixed grout. Real-time mix adjustments ensure perfect material properties for each project's specific requirements.
