URETEK

A multifamily residential building was occupied and in active use — but its timber pile foundation was failing from fungal deterioration. Conventional pile replacement was not feasible. The building could not be vacated.

URETEK rehabilitated the piles in place: fungal inhibitor treatment, void infiltration, and urea-silicate encapsulation at every identified pile. A 4-phase in-place solution that saved the foundation without displacing a single resident.

A Washington, D.C. redevelopment project needed to support new 98-kip column loads on foundations inside a 100-year-old subterranean structure. Pre-injection plate load testing said the ground couldn’t handle it — 1.38 inches of settlement at design load.

URETEK treated the subgrade with chemical injection. Post-injection test result: 0.07 inches. An order-of-magnitude improvement, confirmed by load testing — not estimated.

A California coastal seawall was leaking badly enough to transport backfill out of the embankment. The extent of voiding was unknown. Dewatering was prohibited. Excavation was impossible in the public waterfront corridor.

URETEK injected structural polyurethane through penny-sized access holes — sealing leaks, filling voids, and restoring backfill support along 215 linear feet. Full turbidity monitoring and environmental compliance throughout.

The corridor reopened 15 minutes after the final injection.

A working marine facility on the Oregon coast was slowly sinking into its own foundation — loose saturated sands, active void development, and tidal influence making conditions worse with every cycle.

URETEK stabilized the subgrade with deep polymer injection. No excavation, no dewatering, full marine permit compliance. Crane lifts and boat traffic continued throughout.

Post-injection testing confirmed treated soils with strength comparable to compacted rock.

A deep excavation project in Pelham, NY had a neighbor problem: an occupied 3-story building immediately next door, with the water table well above subgrade. Dewatering without groundwater control meant risking settlement beneath the adjacent foundation.

URETEK installed a chemical grout curtain to control inflow while protecting groundwater levels outside the excavation. Rising-head testing confirmed performance. Monitoring wells tracked settlement throughout.

Zero settlement at the adjacent building. Zero water infiltration at verification locations.

Hurricane Ian’s floodwaters left visible damage — but the bigger problem was underground. Beneath an Altamonte Springs parking garage, soils had washed away from footings and a nearby retention pond kept driving groundwater (and more soil) under the structure even after the storm.

URETEK restored bearing capacity under every undermined footing and installed a grout curtain to cut off the ongoing groundwater migration. Full building operations throughout.

No exterior access. No canal-side staging. No adjacent property access. The leaking seawall joints in this Southwest Florida canal corridor could only be reached from one place: inside the box culvert.

So URETEK sealed them from the inside — injecting a continuous hydrophobic foam barrier at each panel-to-panel joint through ports drilled through the interior panel face.

Leaks controlled. Schedule met. Canal undisturbed.

A Florida marina seawall was slowly losing ground — tidal action pushing water through aging joints and washing out the embankment beneath a busy public waterfront promenade. The void condition was a public safety risk, not just an infrastructure concern.

URETEK sealed every joint and filled every identified void using a 3-depth injection grid. Containment booms protected marina waters throughout. No excavation. No wall replacement.

The city was extremely pleased with the result.

The parking garage beneath a Florida beachfront condominium flooded with every high tide — water pushing through foundation walls driven by coastal groundwater and tidal action. The problem was not going away on its own.

URETEK sealed the structure from below using polymer injection through 700 injection points along the perimeter walls. Ten working days. Garage in use throughout.

No new leaks. Dry garage. Long-term groundwater protection.

A floodwall is only as strong as its weakest point. A coastal service facility in the Bronx had unavoidable discontinuities — utility penetrations and sheet-pile transitions — that created seepage paths under storm surge.

URETEK installed permeation grout curtains at each vulnerable gap. No excavation. No disruption to the active facility. Treated locations stayed dry through tidal cycles.
