Legasea Marina Stabilization
Concrete Settlement at a Coastal Marina
At Legasea Marina, concrete slab settlement had created dangerous conditions for workers and equipment. Prior slab replacements had failed to resolve the underlying soil issues, leaving trip hazards and unstable surfaces for forklifts moving boats valued from $50,000 to over $1 million. Located on wet, sandy soil near the water, the marina faced constant erosion and void formation beneath the slabs. JACKCRETE of Virginia was brought in to provide a long-lasting fix using polyurethane foam injection, avoiding the ineffective cycle of demolition and replacement.
Fast, Non-Disruptive Solution
Using TerraThane 24-003 polyurethane foam, JACKCRETE injected beneath the affected perimeter slabs, approximately 20 feet around previous repairs. The foam filled voids, stabilized the soils, and lifted the slabs back into position. The entire project was completed in two days with zero disruption to marina operations. Forklift traffic is now stable and safe, and trip hazards have been eliminated. The marina remains fully operational with no need for further concrete replacement.
Colonial Williamsburg Golf Course
Restoring Golf Course Walkways
At the prestigious Colonial Williamsburg Golf Course, sidewalk slabs throughout all 18 holes had begun sinking and lifting, creating an uneven and hazardous walking surface. Owned by the Colonial Williamsburg Foundation and host of the annual LPGA Tour, the course needed a fast solution that preserved its historic trees and maintained accessibility. Over 1,800 square feet of sidewalk, spread across 35 different problem areas, needed to be addressed without disrupting play or damaging protected landscaping. JACKCRETE of Virginia was called in to resolve the issue using non-invasive polyurethane foam injection instead of demolition or concrete replacement.
Completed While Golfers Played Through
Using Terrathane 24-010 polyurethane from NCFI Geotechnical, JACKCRETE deployed two rigs to lift and level slabs while preserving the integrity of the historic course. Where tree roots had lifted slabs, the surrounding areas were carefully matched to the highest points to eliminate trip hazards without harming the trees. All 35 areas were restored to grade in a single day, bringing the sidewalks into ADA compliance with no interruption to golf operations. The project was completed without heavy equipment, leaving both the landscaping and the course undisturbed.
Coal Terminal Underpinning
Sealing Underground Tunnel Leaks at a Newport News Coal Terminal
At a busy coal terminal in Newport News, Virginia, an underground vehicle access tunnel beneath an active railroad was suffering from severe water intrusion. Standing water on the tunnel floor and visible leaks along the walls created hazardous driving conditions, especially during winter when ice would render the passage unusable. A large void beneath the structure also raised concerns about long-term stability. JACKCRETE of Virginia was called in to provide a fast, non-disruptive solution using polyurethane injection, avoiding the need for extensive excavation or shutdown of terminal operations.
Watertight Repairs in Just Three Days
Using a combination of Terrathane 24-003 dual-component and Terra-lok 24-120 single-component polyurethane, JACKCRETE sealed leaking joints, filled voids, and eliminated all active water intrusion. The entire tunnel was restored to a watertight state in just three days, with no disruption to the railroad above and nightly reopening of the tunnel to maintain vehicle access. This award-winning project provided a permanent solution to the long-standing problem, delivering both speed and precision with minimal impact to terminal operations.
Midtown Tunnel Entrance Ramp Underpinning
Water Infiltration Under an Artificial Stream
The Midtown Tunnel connecting the cities of Portsmouth and Norfolk in Hampton Roads, Virginia, was showing signs of water infiltration. Moisture was leaking through sections of the approach slabs entering the tunnel, potentially impacting the concrete’s usable life and raising concerns of longevity. Fearing that extensive repairs may be necessary to correct these problems, Elizabeth River Crossings reached out to JACKCRETE of Virginia to solve the issue cost-effectively and with minimal intrusion.
Due to the scope and scale of the project, the JACKCRETE team needed to be prepared. An action plan was drafted and a core drilling firm was consulted to reduce complications and allow JACKCRETE to focus on their core competency. Over the course of the multi-day project, the voids present behind the walls of the tunnel entrance were filled and the breaches eradicated. By reinforcing the concrete slabs with a waterproof barrier, further infiltration was eliminated. Since completion, there have been no reported leaks in the areas worked by the JACKCRETE team.
Roadway Work With Minimal Traffic Disruption
One of the core concerns about fixing these water infiltration issues was the need for extensive, intrusive repairs. Heavy machinery would be on site for weeks, and lane closures would be needed throughout the project. JACKCRETE was able to completely bypass these problems- lane closures were only needed while our team was injecting, and the roadway was otherwise not impacted at all. The only machinery we needed on site was a work truck and a crew truck; no backhoes, excavators, or any other heavy equipment.
Shamin Hotels Region-wide Sidewalk Repairs
Hundreds of Sidewalk Slabs Corrected Throughout Dozens of Hotels
Shamin Hotels is a major player in the Mid-Atlantic region, managing dozens of hotels across the East Coast. With scale comes issues, however- many of their hotel locations were beginning to experience sidewalk settlement. For a company representing top hotel brands and focused on providing exceptional facilities, the presence of dangerous trip hazards was a problem that had to be eliminated as quickly as possible. While swift work was important, it was imperative that repairs not impact the guest experience. No loud noise, no pesky sights or sounds, no closures of facilities. After meeting with the JACKCRETE team, Shamin Hotels was convinced we had what it took.
JACKCRETE restored the safety of the walkways at 31 of Shamin Hotels’ 40+ properties over the course of just 7 days. This was accomplished by scheduling projects by proximity along the 1,300 mile route to ensure multiple hotels were repaired each day. Overall, JACKCRETE lifted over 300 slabs that posed a danger to guests at properties from Glen Allen to Suffolk, Virginia. When work was complete, the hotels were left good as new without any trip hazards that could cause injury.
City of Hampton Concrete Repairs
Leveling Sidewalks, Roadways, and Gutter Systems Throughout Hampton, Virginia
The concrete around the city of Hampton, Virginia was in need of repair. City officials knew the work needed to be done, but wanted to find the right service that would be cost-effective and minimally disruptive to traffic. Experience was also a consideration, needing a contractor that had the background to handle a contract of such magnitude. One of the largest challenges facing the city was the diversity of their issues. Concrete roadway slabs, curb & gutter sections, bridge approaches, stormwater drop inlets, and sidewalk sections all needed to be repaired. Work was even needed at the fire department, where the concrete slabs needed to support their 40,000+ pound trucks. Finding the right company was imperative.
JACKCRETE was able to check all of the boxes. With experience in polyurethane foam dating back to the late 1970’s, the team knew how to uniquely address each of the different areas needing repair. Across the city, diverse concrete issues were repaired without having to be replaced. JACKCRETE’s main advantage was the speed of our work since all repairs were made to heavily-used infrastructure. Our unique process and the expertise of JACKCRETE’s applicators significantly reduced the impact to residents by minimizing or completely avoiding road and bridge closures.
