Foundation Repair

When cracks keep widening, doors stop closing, and floors slope toward one corner, the foundation has moved and the soil under it won't stabilize on its own. We install micropile underpinning, helical piers, and pressure grouting to transfer load past the failure to stable ground below.

Overview

Complete Foundation Repair Solutions

Foundation repair requires understanding why your foundation is failing and designing a solution that addresses the root cause. Our approach combines thorough assessment with proven repair techniques that provide permanent stabilization.

Micropiles are our most versatile foundation repair solution. These small-diameter drilled piles 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. Individual piles handle loads up to 300+ tons.

Helical piers are ideal for lighter residential foundations. These screw-in piles install quickly without the spoils and vibration of drilled systems. We use helical piers for single-family homes, additions, and structures on soft soils.

Pressure grouting addresses foundation problems caused by voids or loose soil. Compaction grouting densifies weak soils; permeation grouting stabilizes sandy or gravelly materials; compensation grouting can lift settled foundations back toward original grade.

For basement walls that are bowing or cracking from lateral earth pressure, tieback anchors provide the restraint needed to stabilize and straighten the wall. We drill through the wall into stable soil beyond, then tension high-strength anchors to hold the wall in place.

Every foundation repair project includes a thorough assessment of existing conditions, subsurface investigation to determine soil properties and depth to stable bearing material, engineered design by licensed professionals, installation by experienced crews, load testing to verify capacity, and documentation for insurance, resale, and peace of mind.

Horizontal Drains
Horizontal Drains icon

Horizontal Drains

Horizontal drains are slightly upward-inclined drilled drains (50 to 500 plus ft, 2 to 4 inch slotted PVC or HDPE) installed into a slope or embankment to lower the groundwater table and relieve the pore pressure that drives landslide movement. Standard slope-drainage tool per TRB Special Report 247 and FHWA-NHI-08-097.

Micropile Underpinning
Micropile Underpinning icon

Micropile Underpinning

Micropile underpinning strengthens or replaces an existing foundation by transferring load to deeper bearing strata through small-diameter drilled-and-grouted piles, allowing settled or undersized foundations to be repaired without demolishing the structure above.

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 icon

Pressure Grouting

Pressure grouting injects fluid grout into soil pores, rock fractures, or open voids to densify loose ground, seal water pathways, fill cavities, and lift settled foundations. Compaction, permeation, fracture, and chemical grouting variants address different host-ground conditions.

Tieback Anchors
Tieback Anchors icon

Tieback Anchors

Tieback anchors are post-tensioned ground anchors that drill through a wall facing into competent soil or rock, develop bond along a deep fixed length, and are stressed to lock in 100 to 600 plus kips of holding load. They provide the active lateral restraint behind soldier pile walls, secant pile walls, foundation tie-ins, and dam abutments where passive systems would not develop adequate capacity.

Questions

Foundation Repair FAQ

Foundation repair costs depend on the number of piers or piles needed, depth to stable bearing material, access conditions, and the type of repair system. Residential projects typically range from $15,000 to $100,000+, with most homes falling in the $25,000-$60,000 range. Commercial and infrastructure projects vary widely based on scope. We provide detailed estimates after a site assessment, early repair is almost always less expensive than waiting for conditions to worsen.
Warning signs include: cracks in interior walls (especially stair-step or diagonal cracks), cracks in exterior brick or block, doors and windows that stick or won't close properly, sloping or uneven floors, gaps between walls and ceiling or floor, visible settling of the structure, and cracks in the foundation itself. If you notice any of these signs, a professional assessment can determine whether they indicate foundation problems requiring repair.
In most cases, yes. Our low-headroom equipment and clean drilling methods allow us to work inside occupied homes. We access the foundation through strategic floor openings, complete the repairs, and restore flooring when done. Some areas may be temporarily off-limits, but many homeowners continue living in their homes throughout the project.
Most residential foundation repairs take 1-3 weeks depending on the number of piles and access conditions. The piles reach design capacity within days of grouting, allowing rapid load transfer. We coordinate work to minimize disruption and maintain access to critical areas of your home.
Yes. Properly designed micropile underpinning provides permanent foundation support with a design life exceeding 75 years. We use corrosion-protected steel reinforcement and durable grout to ensure long-term performance. Our repairs often provide better support than the original foundation because piles extend to deeper, more stable bearing material.
Common causes include: weak or compressible soils that can't support the foundation load, poor drainage allowing water to saturate and weaken soil, tree roots extracting moisture and causing soil shrinkage, improper site preparation during original construction, erosion undermining the foundation, slope movement or landslides, and natural settling over time. We identify the root cause during our assessment to ensure our repair addresses the underlying problem.
Foundation repair protects and often increases your home's value. Unrepaired foundation problems can reduce home value by 10-15% and make properties difficult to sell. A professionally repaired foundation with documentation gives buyers confidence and removes a major obstacle to sale. Many homeowners report that foundation repair paid for itself at resale.
Yes. Our foundation repairs include warranties on materials and workmanship. The specific warranty terms depend on the repair system and project conditions. We also provide complete documentation of the repair, including load test results, that you can share with future buyers or insurance companies.
In many cases, yes. Once underpinning piles are installed, we can use hydraulic jacks to carefully lift settled portions of the foundation back toward original grade. The amount of lift possible depends on the structure's condition and how much movement has occurred. We assess lift potential during our evaluation and discuss realistic expectations before work begins.
Micropiles are drilled and grouted, a hole is drilled, reinforcement placed, and grout pumped to create a bonded pile. They work in any soil or rock and develop high capacity through grout-ground bond. Helical piers are screwed in like large screws and develop capacity through bearing on helical plates. Helicals are faster to install and work well in soft soils, but micropiles are more versatile for hard soils, rock, and high-capacity applications.

"We engaged Rock Supremacy for a very challenging cliffside project that involved the stabilization and reinforcement of a retaining wall which ultimately required a total of ten drilled horizontal rock anchors, multiple vertical stabilization pilings and encapsulation with concrete structural reinforcement. Even though my residential project, as large as it was to me, was of a much smaller scale than the company often deals with, it approached the task with all of the consideration and professionalism I could hope for. Notably, they were not hesitant to take on a challenging terrain even with its limited access. From the outset, Corey Muir was very engaged in the project and with finding workable solutions. He was eager to explore alternative options for accomplishing the goals and worked diligently with my engineering consultants to tweak the design for a practical, affordable solution. Throughout the planning process, he maintained excellent communications with myself and our structural engineers. Corey was careful to make sure, prior to our final agreement, that all details were fully understood. The company began the project exactly when anticipated. The on-site crew, David, Nate and Jules proved to be the "A" team. They are very skilled and professional. I found them considerate, easy to interact with, and flexible with regard to change possibilities. The team showed careful concern for my property and all possible avoidance of collateral damage while completing a job that involved some very heavy equipment. When the concrete supplier was unduly delayed, they took it in stride and made the best of the situation. The job was actually finished a little ahead of schedule. Definitely a five star rating for this group, I would be happy to further discuss my experience with anyone contemplating the use of Rock Supremacy's services."
