Pressure Grouting
Small holes are drilled and tubes driven under the perimeter footing, and through the tubes a cementitious grout, cement sand-slurry, polyurethane foam, or other chemical mixture is “injected” into the soil, filling voids and strengthening the soil.
Why it makes sense: Most cost-effective repair and least invasive. Quick cure time and most projects completed in less than 3 days.
Risks: Highest potential for future movement after repair if grading and drainage is not properly serviced and maintained. Most contractors provide estimates to certain depths, and if failures exist beyond those depths
Push Piers
Steel brackets are attached to the footing, then rugged steel tubes are hydraulically driven through bad soil down to competent soil. The result is lifting the home and transferring significant building loads to bedrock or competent strata.
Why it makes sense: Takes soil out of the equation and lifts the home back to as level as possible. Provides the best possible lifting opportunity.
Risks: Does not remediate lateral movement or any other form of movement other than vertical settlement.
Helical Piers
Steel tubes with blades are screwed into the ground to target depths and torques as designed by an Engineer. After targets are achieved, brackets are attached to the footing and the building is lifted.
Why it makes sense: Although more expensive, these piers resist both settlement and heave, and provides a degree of lateral resistance.
Risks: Improper design or failure to use an Engineer can lead to improper depths or torques, rendering the repair ineffective. Greater depths significantly increase costs.
