Installation Records For Every Pier
Depth, torque, final driving pressure and location are logged for each element, giving engineers and owners a verifiable record of what is under the building.
About Us
To restore and preserve the structures people depend on by transferring their loads to reliable soil and rock, with engineering discipline, careful installation and records that prove the work.
Who We Are
About Our Company
Invraplusinfrastructure.com is a foundation contractor specializing in underpinning, structural stabilization and deep foundation retrofit. We install helical piers, push piers, micropiles and grouted systems that transfer load from distressed footings to stable soil or bedrock, working from design drawings prepared by licensed engineers. Our crews are trained in torque-correlated helical installation, hydraulic push pier driving to refusal, drilling and grouting micropiles, and the lift-and-level procedures that follow. Every project includes documented installation records, so engineers and owners can verify depth, torque, capacity and final load.
Serving and neighboring regions, Invraplusinfrastructure.com works on residential, commercial, industrial and historic structures where soil movement, poor fill, expansive clay, erosion or nearby excavation has compromised the foundation. We perform our own installations rather than subcontracting the critical work, and we take the time to understand why the structure moved before proposing a fix. Our goal is lasting stability: addressing the cause, installing proven systems and leaving the building safer, level and ready for use.
Core Capabilities
- Post-installation elevations are surveyed and compared against pre-work levels.
- Settlement cause is investigated including drainage, soils and loading.
- Load transfer brackets are installed to the manufacturer's specification.
- Lifting is monitored with levels and is halted if distress is observed.
- Installation torque or driving pressure is recorded for every pier installed.
- Pier depth and termination in competent material are documented per location.
Our Mission
To treat every foundation problem as a diagnosis first and a repair second, so the solution matches the cause and the building stays stable for decades.
Our Advantages
Why Clients Choose Us
Lift And Level Experience
Controlled hydraulic lifting restores elevation gradually, protecting finishes and plumbing, with monitoring so movement stops where the engineer specifies.
Engineer-Backed Designs
We work from geotechnical data and stamped drawings, with capacities verified by installation torque, driving force or load testing as the design requires.
Minimal Disruption
Many installations require no heavy demolition and little spoil removal, which keeps occupied buildings in use and reduces restoration costs afterward.
Root Cause Thinking
We examine drainage, soil moisture, utilities and original footing design, because stabilization fails when the cause of movement remains.
Low-Headroom Capability
Compact rigs and hand-held equipment get deep foundations into basements, crawlspaces and tight alleys where large piling rigs cannot operate.
Disruption Kept Down
Access routes, excavation extents and reinstatement are agreed in advance, so the repair does not leave you with a landscaping project as well.
Cause Investigated First
Drainage, soils, trees and loading are examined before piering, since treating the symptom of a plumbing leak leaves you with both problems.
Lifting Judged Carefully
Recovering elevation is only proposed where the structure can tolerate it, because lifting a rigid building can cause more damage than the settlement did.

Insights & Updates
Reading Cracks: What They Say About Settlement
Diagonal, stair-step and horizontal cracks tell different stories. We outline how patterns hint at the cause of movement and when professional evaluation is needed.
Torque Correlation In Helical Pier Capacity
Installation torque is a practical indicator of helical pier capacity. We explain correlation factors, limits and why load testing still matters on critical projects.
Protecting Neighbors During Deep Excavation
Adding a basement or building next to an existing structure demands careful underpinning, monitoring and communication. A look at sequencing and settlement thresholds.
Drainage Problems Behind Many Foundation Failures
Poor grading and downspout discharge saturate soils and erode support. Stabilization works best when water management is corrected alongside the piers.
Client Feedback
What Clients Say
They explained why the building moved, not just how to prop it up. The piers were logged one by one, the lift was gradual, and the readings afterward gave our engineer exactly the confirmation she wanted.
H. LindqvistOwner, Commercial Property
Our neighbor was nervous about the excavation next to their wall. The underpinning sequence and monitoring plan kept everyone calm, and we never saw movement beyond the limits set in the design.
G. PetrenkoDevelopment Manager, Residential Builder
They got micropiles into a basement with barely any headroom and finished ahead of the plant outage. The paperwork was clean and accepted by our engineer without comments.
