CERTIFIED CONTRACTOR
Bristol FX is a Certified Deep Foamjection™ Contractor
Bristol FX — through our parent company Foundation Tech, Inc. — is a certified polyurethane deep injection contractor trained and authorized to install HMI’s patented Deep Foamjection™ system. Our team has injected over 1 million pounds of foam to lift and stabilize properties across the western United States.

THE SOLUTION
A Smarter Way to Stabilize & Lift
Traditional foundation and soil repair methods are invasive, expensive, and time-consuming — requiring heavy excavation equipment, days of disruption, and significant property damage just to access the problem area. Polyurethane foam injection changes everything.
Using dime-sized holes and precision injection tubes, Bristol FX delivers high-density structural foam directly to the source of the problem — deep underground — where it expands, fills voids, strengthens weak soil, and lifts settling structures back to their original position. Faster, cleaner, and more affordable than any traditional alternative.
Bristol FX has been injecting polyurethane foam for over 14 years — making us true experts at diagnosing exactly when foam injection will solve your specific problem, and when more extensive repairs are needed.
Our Honest Assessment
Polyurethane foam is not always the right answer for every foundation problem. Severe structural damage, major foundation movement, or certain soil conditions require more robust solutions like push piers or helical piers. Bristol FX will always recommend the right solution for your situation — not the most expensive one.
WARNING SIGNS
Is Foam Injection the Answer for Your Property?
These are the signs that tell us foam injection is likely the right solution. If you’re seeing one or more of these on your property, a free inspection will confirm it.
- ✓ Sunken or uneven driveway, sidewalk, or patio
- ✓ Concrete slabs that rock or move when walked on
- ✓ Trip hazards at slab joints or edges
- ✓ Gaps forming under slabs or at foundation edges
- ✓ Pool deck panels that have shifted or dropped
- ✓ Garage floor sloping toward or away from the door
- ✓ Water pooling on or around concrete slabs
- ✓ Foundation settling — doors sticking, floors sloping
THE SMART CHOICE
Repair vs. Replace — Why Foam Wins Every Time
01
Save Up To 70%
Foam lifting and soil stabilization costs a fraction of full concrete replacement or traditional excavation-based foundation repair.
02
Same-Day Results
Most repairs are completed in a single visit. Concrete slabs can be walked or driven on within hours of treatment — not days.
03
No Demolition
No jackhammers. No hauling. No concrete waste. Your property stays clean and intact throughout the entire process.
04
Permanent Fix
HMI structural foam does not biodegrade, wash away, or compress over time. We address the root cause — not just the surface symptom.
ADVANCED TECHNOLOGY
Deep Foamjection™ by HMI
Deep Foamjection™ is HMI’s patented, trenchless process for deep soil stabilization and foundation repair. Unlike traditional concrete raising methods that only address surface-level problems, Deep Foamjection™ targets the root cause — unstable, voided, or water-eroded soil deep beneath your structure.
What Makes Deep Foamjection™ Different
- ✓ Reaches depths far beyond traditional slabjacking methods
- ✓ HMI hydrophobic structural foam injected at over 124 PSI
- ✓ Sets up in wet conditions — displaces water as it expands
- ✓ Trenchless — no excavation, no heavy machinery
- ✓ Fills voids and increases soil load-bearing capacity
- ✓ Permanent, faster, and cleaner than traditional methods
- ✓ Completed in hours — not days of disruption
THE PROCESS
The 4-Step Deep Foamjection™ Process
Drill
Small, dime-sized holes are drilled through the slab or into the ground at precisely calculated locations — no large openings, no heavy equipment.
Place
Injection tubes are placed at specific, engineered depths — targeting the exact layer of weak, voided, or water-eroded soil causing the problem.
Pump
HMI’s hydrophobic structural foam is pumped at over 124 PSI, expanding rapidly to fill voids, displace water, bind soil, and lift the structure above.
Verify
Results are verified on-site. Lift levels are confirmed, holes are patched, and your property is restored — often within the same day.
APPLICATIONS
Where We Use Deep Foamjection™
APPLICATION 1
Foundation Stabilization & Settlement Repair
When soil beneath a foundation loses strength due to erosion, drought-shrinkage, or poor compaction, the foundation above begins to settle unevenly. Deep Foamjection™ targets this weak soil layer directly — injecting structural foam deep beneath the footing to stabilize, strengthen, and lift the settling foundation without any excavation.
This is especially effective for homes where pier installation is not practical due to access limitations, or where soil improvement rather than structural underpinning is the appropriate solution.
- ✓ Stabilizes weak or voided soil beneath foundations
- ✓ Lifts settled foundations back toward original position
- ✓ No excavation — trenchless process
- ✓ Works in wet or water-saturated soil conditions
APPLICATION 2
Sinking Concrete Slabs
Driveways, sidewalks, patios, pool decks, garage floors, and commercial slabs all sink for the same reason — the soil beneath them loses density and voids form. Deep Foamjection™ fills those voids from below, lifting the slab back to level and preventing future settlement.
Around swimming pools, slab settlement creates particularly hazardous conditions where wet feet and uneven concrete combine to create dangerous falls. Pool decking that has settled also allows water to pool against your home’s foundation — creating moisture problems and potential structural damage.
- ✓ Driveways, sidewalks & walkways
- ✓ Pool decks & patios
- ✓ Garage floors & warehouse slabs
- ✓ Roads & commercial paving
APPLICATION 3
Seawalls, Roads & Soil Stabilization
Deep Foamjection™ is uniquely suited for applications where water is part of the problem. HMI’s hydrophobic foam is specifically engineered to set up in wet and saturated conditions — actually displacing water as it expands and cures. This makes it ideal for seawall void filling, road base stabilization, and any application where traditional dry-fill methods would fail.
For hillside stabilization, deep injection at multiple depths and locations binds unstable slope soil and prevents erosion-driven movement — protecting homes and structures from slope failure.
- ✓ Seawall void filling & stabilization
- ✓ Road base & subgrade stabilization
- ✓ Waterfront & marine structure repair
- ✓ Works in fully saturated soil conditions

FAQ
Frequently Asked Questions
What is polyurethane geotechnical foam and how is it used in foundation repair?
Polyurethane foam is a rapidly expanding material used to lift concrete slabs, stabilize foundations, and improve soil compaction beneath your home. It can also block excess water from saturating the soil below your foundation.
What is polyurethane slab lifting?
Polyurethane slab lifting involves injecting expanding foam through small ports in your concrete to lift and stabilize settled slabs. This is a fast, non-invasive process that restores level surfaces with minimal disruption.
What is deep foam injection, and when is it needed?
Deep foam injection delivers specialized geotechnical foam deep into the soil to stabilize loose or poorly compacted ground. The foam expands to compact and strengthen the soil, helping to support foundations and prevent further settlement.
Can polyurethane foam be used for water mitigation?
Yes. The foam can be strategically injected to block water infiltration and reduce the risk of water-related foundation problems, keeping your home’s foundation dry and secure.
Is foam injection a permanent solution?
When foam injection is the right solution for your specific situation, it provides permanent results. The foam does not biodegrade, wash away, or compress over time. Bristol FX’s 14 years of expertise ensures you get the right diagnosis and the right fix the first time.
