Foundation & Infrastructure Support
Specialized foundation support services including micropiles, underpinning, and ground improvement for structures on challenging soil, settling foundations, and infrastructure requiring enhanced capacity.
Understanding Foundation & Infrastructure Support
Foundation support requires understanding why existing foundations are failing and designing systems that provide permanent solutions. Our approach combines geotechnical investigation to identify ground conditions with specialized installation techniques that work in challenging access situations.
Micropiles are our most versatile underpinning solution—small-diameter drilled piles that develop high capacity through friction in dense soil or rock bond. Our low-headroom drill rigs work in basements with only 6 feet of clearance, allowing micropile underpinning inside existing structures. Piles can handle loads up to 500 kips and work in any soil or rock condition.
Tieback anchors provide lateral support for foundations affected by slope movement or overturning loads. High-capacity PTI-certified anchors resist forces up to 500 kips while maintaining structure stability during construction. Rock anchoring secures structures to bedrock for seismic and wind load resistance.
Pressure grouting fills voids beneath foundations and improves surrounding soil. Compaction grouting densifies loose soils; permeation grouting stabilizes granular materials; compensation grouting can even lift settled structures back toward original grade.
For foundations threatened by adjacent excavation or slope movement, soldier pile walls provide earth retention during construction. Horizontal drains address groundwater that may be contributing to settlement or instability.
Specialized applications include dam and spillway stabilization using tensioned anchors and grouting, bridge pier rehabilitation with micropile groups, and historic building preservation requiring minimal vibration and maximum care. Our drilling capabilities handle any ground condition from soft alluvium to granite.
When Foundation Support Is Needed
You may require foundation stabilization or improvement when you notice: settlement or cracking in structures; tilting or rotation of retaining walls; soil loss or void formation beneath slabs or footings; groundwater infiltration or erosion undermining support; increased loading from new construction or road widening; slope movement affecting foundations; or pavement deflection or subsurface voids. Early intervention prevents costly structural damage and safety risks.
Without proper intervention, these conditions typically worsen over time. Early assessment and appropriate remediation can prevent costly emergency repairs and protect the assets and people that depend on stable ground.
Common Causes
- Weak, compressible, or collapsible soils
- Undetected voids or subsurface erosion
- Groundwater pressure and poor drainage
- Overloading or design-life exceedance
- Seasonal moisture changes or frost heave
- Construction vibration or excavation nearby
- Slope movement affecting foundations
- Bearing capacity failure in weak ground
- Deterioration of original foundation materials
- Seismic damage to foundation elements
Restoring Foundation Integrity
We approach foundation problems systematically—first understanding why the foundation is failing, then designing solutions that address root causes while providing lasting support. Our techniques work in any soil condition and can be installed with minimal disruption to occupied structures.
Foundation Assessment
Document existing conditions including crack patterns, settlement measurements, structural distress, and drainage issues. Assessment identifies the failure mechanism and establishes baseline for measuring repair effectiveness.
Subsurface Investigation
Borings and soil testing determine soil properties, depth to competent bearing material, and groundwater conditions. This data is essential for designing underpinning systems that will perform long-term.
Engineering Design
Engineers analyze existing loads, required capacity, and installation constraints to design the optimal foundation support system. Design considers access limitations, vibration sensitivity, and construction sequence.
Deep Foundation Installation
Micropiles, helical piles, or driven piles are installed adjacent to or through existing foundations. Piles extend to competent bearing strata, developing capacity through end bearing, side friction, or both.
Load Transfer
Structural connections transfer loads from existing foundations to new piles. Connections may include pile caps, brackets, grade beams, or direct attachment depending on foundation type and access.
Verification & Monitoring
Load testing verifies pile capacity meets design requirements. Monitoring tracks settlement and confirms stabilization. Documentation provides records for owner, engineer, and insurance purposes.

Why Choose Rock Supremacy
Techniques We Use
Proven engineering methods that deliver long-term stability and protection.
Cable Anchors
Cable anchors (also known as strand anchors or post-tensioned anchors) provide high-capacity reinforcement for slopes, retaining systems, cut faces, and rock masses. These anchors transfer load deep into competent ground, offering reliable, long-term stabilization.
Epoxy-Grouted Dowels
Epoxy-grouted dowels provide rapid-set, high-strength reinforcement by bonding steel bars into holes drilled in rock or concrete. This technique is ideal for small to medium stabilization tasks, repairs, or situations requiring fast loading and strong adhesive properties.
H-Pile Walls
H-pile walls use driven or drilled steel H-beams with lagging between flanges to create robust earth retention systems for deep excavations, bridge abutments, and permanent retaining structures.
Horizontal Drains
Horizontal drains are drilled drainage systems designed to lower groundwater pressure and improve the stability of slopes, embankments, and rock faces. By relieving pore pressure, these drains significantly reduce the risk of landslides, sloughing, and long-term slope movement.
Micropile Underpinning
Micropile underpinning strengthens existing foundations by transferring loads into deeper, more competent soil or rock. This technique is essential for repairing settlement, stabilizing structures in landslide areas, or supporting new loads for renovations and expansions.
Micropiles
Micropiles are small-diameter, high-strength deep foundation elements used to transfer loads into competent ground. Their versatility makes them ideal for underpinning, slope stabilization, and situations with limited access or difficult geology.
Pressure Grouting
Pressure grouting strengthens ground, fills voids, and reduces water infiltration by injecting grout into soil, fractured rock, or void spaces. This technique supports slope stabilization, foundation improvement, landslide remediation, and structural repairs.
Rock Bolting
Rock bolting stabilizes fractured, jointed, or unstable rock masses by anchoring steel bars deep into competent rock. By tying loose blocks back to stable substrate, rock bolts improve the overall strength and cohesion of slopes, cuts, tunnels, and vertical faces.
Soldier Pile Walls
Soldier pile walls are proven earth retention systems for stabilizing deep excavations and steep slopes. Steel beams installed at intervals with lagging placed between them provide flexible, economical support that adapts to site constraints.
Structural Shotcrete
Structural shotcrete is high-strength, reinforced concrete applied pneumatically to create durable retaining walls, tunnel linings, and slope support systems. Engineered to carry significant loads, it provides monolithic construction that conforms to irregular surfaces.
Tieback Anchors
Tieback anchors provide active lateral reinforcement for retaining walls, excavation support systems, and slope stabilization by transferring loads deep into stable ground or rock. These post-tensioned elements are essential for deep excavations and high-load applications.
Weep Drains
Weep drains provide surface-level drainage relief by allowing water trapped behind shotcrete, retaining walls, or stabilized slopes to escape. These drains prevent hydrostatic pressure buildup, which can compromise structural stability.
Industries Impacted
We serve these sectors with specialized expertise in their unique challenges and regulatory requirements.
