NYSTA also noted that a local contractor without roadway experience had previously tried unsuccessfully to bring the slabs back to grade and, while doing so, partially damaged the slabs. Analysis A visit to the site determined that this bridge’s sleeper slab design provided an unusually small footprint for the transition from the approach to the roadway. Due to the smaller footprint and the previous damage, this job had gotten a lot more complicated from an operations standpoint. URETEK’s on-site supervisor and his operations team’s experience was vital in preventing any further damage while bringing the sleeper and approach slabs back to grade as much as the structure would allow. Solution For the bridge stabilization effort, URETEK used the URETEK Deep Injection® (UDI) process and the patented URETEK 486 STAR® polymer to stabilize the soils under the roadway. Dynamic Cone Penetrometer (DCP) testing assessed preinjection soil conditions in each work area and confirmed the operations team’s injection plan. Crews then drilled injection holes on 4’ centers and installed injection tubes at three elevations. The team injected the highly expansive, high strength, lightweight, water-resistant URETEK 486 STAR polymer through the tubes and into the soils beneath the base to fill the voids & stabilize them. Injection continued until 1mm of movement was detected at the roadway’s surface, confirming adequate soil stabilization. Eventually, proper lift was achieved. Result NYSTA was delighted with the result of URETEK’s work. The operations team brought the bridge back to within a ½” of the original grade. The approaches were also lifted at the transition areas so that snowplow drivers could better operate the vehicle without fear of damaging the blades of the plows. For traffic in Buffalo, URETEK provided a repair solution that restored motorists’ smooth ride, and the life span of the bridge was increased at a fraction of cost and labor. URETEK Deep Injection® (UDI) Widely referenced throughout our industry, UDI involves the injection of structural polymer into base and subgrade soils to increase the load bearing capacity. This is achieved by injecting the polymer through small holes drilled directly through the pavement structure to depths determined by site-specific analysis. Our URETEK 486 Star® material flows easily into voids and weak zones within the soil mass below. Through a controlled chemical reaction, the expanding polymer compacts surrounding soils and applies a controlled pressure on targeted areas of the affected pavement above. If needed, a multi-injection design plan is utilized to gently return the pavement to its original grade. The composite material quickly cures into a strong, dimensionally stable, and water-resistant geo-material, providing years of reliable service. URETEK 486 Star® URETEK 486 Star® polymer is a two-component, high-density, expanding thermoset polyurethane system. It was developed to be the ideal solution for under-sealing, void filling, lifting of settled pavement, stabilization and stiffening of weak soils, and for encapsulating and sealing buried infrastructure. URETEK 486 Star® is environmentally inert, non-toxic, and resists underground water erosion or weakening due to its industry-leading hydrophobic properties. Download Case Study Read MoreBridge Settlement Operation in Binghamton, New YorkBridge Settlement Operation in Binghamton, New YorkProblem In Binghamton, NY, significant settlement of up to 2 ½” to 3” had developed transversely across the highway on I-81. It stretched across an area approximately 122’W x 60’L. Moving south across the highway, the settlement created unsafe driving conditions, which was noticeable to passing traffic in an area with very high traffic volume. The area was a central crossing point for the trucking industry and commuter traffic as a passageway in all directions; going west to the southern tier, east to Albany, north to Syracuse, and south to Pennsylvania and beyond. Analysis The customer stated that there was 6’ of soil/fill to work with between the concrete slabs and the bridge structures. URETEK addressed four lanes of traffic in each direction for a total treated area of approximately 7320 sq. ft. (122’x60’). Solution URETEK used the patented URETEK Deep Injection® (UDI) process and URETEK 486 Star polymer to stabilize the soils under the roadway. Making use of a surface grid pattern of approximately 4’x 4’, the operations crew drilled host holes based on the optimal injection depth(s) as determined by Dynamic Cone Penetrometer testing. Injections continued after stabilization to return the required lift back to grade. URETEK used an average settlement grade of 1 ½” to determine the estimated material usage and pricing for this project. Laser instruments monitored the surface to ensure sufficient soil stabilization. Result During the bridge stabilization project in Binghamton, URETEK was able to lift the slabs back to their original grade in two nights of work without any need for excavation while stabilizing the remaining soils and filling voids under the slabs. As operation crews moved transversely across the highway, the original settlement issue was corrected while improving driver safety conditions. Thanks to URETEK, the project was completed successfully while being 60% under budget.

The existing structure is supported by drilled shafts extending into solid rock. The slab, however, is supported by 30’ plus of backfill material. Consolidation of the backfill material had caused slab settlement and voids, creating trip hazards for patients and health care workers throughout the facility. With the safety of surrounding personal compromised, URETEK was called to rectify the settlement issue. Analysis A local consulting firm completed a geotechnical exploration to evaluate the condition of underlying soils. The slab was cored in 12 locations to evaluate the subgrade soils. The study detected weak soils and several voids as large as 1.5” below the slab. URETEK Deep Injection® (UDI) and URETEK Method Injection were proposed for the project as a quick and effective way to stabilize the underlying soils while providing a lift to the settled slab. Solution For the slab settlement project in Henderson, UDI combined with Method was the ideal solution to lift the slab back to grade and stabilize the soils below. During the repairs, URETEK crew performed the Method Process in a grid pattern across the compromised area. UDI was used to stabilize and fill voids along an external grade beam. Crewmembers injected URETEK 486 Star® polymer into the subgrade soils according to a site-specific injection plan. This both stabilized the weak fill soils and filled all voids to ensure that the slab’s bearing capacity requirements were met. Result UDI stabilized the slab, increased the compressive strength of the soils below, and improved safety of hospital personnel. The owner was pleased with the result. Settled slabs were lifted back to grade to alleviate tripping hazards. The repair was completed at night to avoid downtime for the tenants, and all flooring and furniture were left in place during the installation. The tenants were able to work during the day between the crews’ night shifts. Thanks to URETEK, the operation was completed ahead of schedule and with no downtime for the tenants.

These dips and the problems associated with the weak surrounding soils presented both rideability and safety issues for motorists. To preserve commuter traffic flow, engineers needed a solution to salvage their weak subbase soils, so they decided to call URETEK. Analysis URETEK arrived on location, and after some research, it was confirmed that settlement was not the result of faults in the culvert pipes but weak fill soils around them. Dynamic Cone Penetrometer (DCP) testing evaluated the depth of treatment. Low blow counts were encountered mostly to -4’ and as deep as -8’ in some locations. URETEK Deep Injection® (UDI) was proposed for the project as a quick and effective way to stabilize the underlying soils. Solution For the Corbin project, UDI was the perfect solution to repair the culverts and taper out the dips. URETEK crews performed the process, injecting URETEK 486 Star® polymer in a grid pattern over the dip areas. During repairs, one lane was left open while the procedure was completed in the other. Virtually no damage was done to the pavement by using only ¾” holes to complete the operation. Result URETEK was able to stabilize the soils and even out the dips in the culverts. KYTC District 11 engineers were pleased with the results. Compared to full depth replacement and repeated mill and overlay, repair time was significantly reduced by leaving the subbase soils and the pavement in place. The road remained open during the whole process; work was completed in one lane while traffic flowed in the other. URETEK was able to eliminate rideability issues without halting traffic flow while providing long-term repairs that ensured the safety of motorists and the crew.

After inspection, it was determined that the metal had rusted out. Along with other, smaller areas of disrepair along the pipe, this decreased the operational purpose of the culvert because the stream bed was flowing under it, not through it. This destabilized the soils around the culvert, causing settlement of the roadway and a small sinkhole to develop. Significant settlement of approximately 4” had formed across the lanes and shoulders of the twolane asphalt roadway. Analysis URETEK arrived at the location and determined that crews would need to build a protective wall around the culvert’s top and sides to restore the soils’ bearing capacity above and around the culvert. Once the voids were filled around the culvert, URETEK would need to have the bottom section repaired to get the water flowing back through the culvert. Dynamic Cone Penetrometer (DCP) testing determined optimum injection depths for the URETEK Deep Injection® (UDI) process. Solution For the soil stabilization effort in Town of Florida, UDI was employed by injecting our 486 Star® polymer to stabilize the soils under the roadway and around and above the culvert. Crews also injected at an angle from inside the culvert, injecting every 4 feet running the full 60’ length to fill the voids and stabilize the pipe’s lower section. Crews would inject a few feet from the bottom of the culvert on each side, injecting into the soils using a surface grid pattern of approximately 4’x 4’. The work area on the road was approximately 42’ wide by 40’ long. After a successful process, all injection tubes were recessed and grouted after the completion of the project. Result MassDOT was delighted with the result of URETEK’s work. The soils were stabilized above and around the culvert using multiple injection techniques. URETEK started the project in the winter and even worked during a snowstorm, stopping only when the weather became a safety issue. The project was completed during the following spring. The culvert was interlined, and water is now flowing through the pipe without hindrance. After a significant culvert repair operation in Town of Florida, Massachusetts, URETEK provided efficient, attentive, and cost-effective repair solutions that will outlast traditional methods.

The station was about 20 years old, with settlement only occurring in the last five years. The wet well was 10’ in diameter, extended 23’ below grade, and was experiencing about 1” of differential settlement. Surrounding the wet well was a transformer pad and a valve pit that had settled as well. After careful consideration, the city called URETEK. Analysis A local consulting firm completed a geotechnical exploration to evaluate the condition of underlying soils. Soil borings were conducted at various locations around the site. Weak clay backfill was discovered in some areas, particularly around and beneath the wet well. Based on the soil borings, bedrock was encountered an additional 10’ beneath the wet well. After all necessary testing was completed, URETEK Deep Injection® (UDI) was proposed to bypass the rock and solve the settlement issue. Solution UDI was an excellent solution to stabilize the wet well, valve pit, and transformer pad. URETEK crew performed the UDI process using URETEK 486 Star® polymer in a grid pattern beneath all three structures. For the crew to access the floor of the wet well, the sanitary flow had to be diverted, and the well had to be pumped out. This area was also beneath the water table, so the crew was injecting against head pressure while avoiding flooding their workspace. Result URETEK successfully stabilized the foundation beneath the transformer pad, valve pit, and wet well. The city was delighted with the results. Due to the wet well’s depth, traditional excavation would have required removing the transformer pad and valve pit while disconnecting all electric connections and plumbing. The 25’ plus excavation in weak clay soils would have needed sheet pile walls or benching. URETEK provided significant savings to time and cost by leaving the underground structures in place and stabilizing the existing soils.

However, Moxy was required to preserve and reuse the front face of the building. Due to structural age and limited accessibility, the contractor and engineer decided that a shear wall would be installed in the basement to extend the structure’s full height. This would support the front face during demolition. The foundation soils beneath the new shear wall needed to be strengthened to support the construction loads. The engineer recommended using URETEK. Analysis A consulting firm in Cincinnati completed a geotechnical exploration of the problem area. The study encountered voids and weak soils in the fill material just below the proposed location of the shear wall foundation. The largest void found was 2.5”, and the fill soils were composed of loose to medium dense sand, which were not adequate for foundation support. Due to access limitations, there was no way to get any excavation equipment into the building, so hand digging and removal of the slab by hand would have been required without URETEK. Solution URETEK Deep Injection® (UDI) was proposed as a quick and effective way to fill and stabilize the underlying soils for the operation. URETEK crews performed the UDI process in a grid pattern across the proposed foundation area. They injected URETEK 486 Star® polymer into the foundation area according to a site-specific injection plan. This both stabilized the weak fill soils and filled all voids to ensure that bearing capacity requirements were met. Result URETEK completed the repair in 1 day, and the owner was delighted with the results. This would have been a multiday process with many other challenges like removing, replacing, and compacting fill material and concrete. The UDI process easily provided the required 1500 psf bearing capacity. It also improved constructability by allowing foundation construction to be completed on top of the existing slab.

As part of the project, a box overpass was constructed for traffic to access a rest area just past the new exit. Soon after construction, settlement began to occur around the box overpass in all four lanes. Patching efforts were unsuccessful as the area continued to settle. Kentucky Transportation Cabinet began receiving more and more complaints from motorists about this area. The client needed the safety and rideability issues remediated immediately. Analysis A site visit and some research into the construction process confirmed URETEK’s assumptions that fill soils were likely poorly compacted. It was determined that the URETEK Deep Injection (UDI) was the best solution for KYTC. URETEK arrived at the location and used Dynamic Cone Penetrometer (DCP) testing on both the eastbound and southbound lanes to evaluate the area’s soil strength. It was determined that the EB lane only needed a correction of -4’ while the WB lane needed a correction of-8’. The goal was to fix all safety and rideability issues. Solution For the soil stabilization effort in Georgetown, URETEK Deep Injection® (UDI) was employed by injecting the 486 Star® polymer into the soils across all four lanes to increase soil strength enough to carry traffic loads. This both stabilized the subbase soil and tapered out the dips, restoring the safety and rideability to the Lexus Way corridor. The crews were able to save time and preserve commuter routes by keeping only one lane closed during work hours to ensure a steady traffic flow. Result URETEK stabilized the underlying soils and lifted the asphalt roadway back to grade without causing significant traffic closures. KYTC District 7 engineers were pleased with the results. After receiving numerous complaints from motorists prior to the procedure, they were delighted to have had none since completion. Compared to full depth replacement and repeated mill and overlay, the time of repair was greatly reduced due to the preservation of the subbase soils and the pavement. Due to this, the cost was significantly reduced. Virtually no damage was done to the pavement by using only ¾” holes to complete the UDI.

Despite trying to repair the problem with mud jacking grout in the past, the dip kept reappearing. This had been a problem for the local NYSDOT Maintenance Residency Office and its heavily traveled commuter traffic to the Syracuse area for years. Analysis URETEK arrived at the location and assessed that water was probably coursing under the roadway and coming off a hill and under the street before creating sinkholes in the highway’s median strip. Dynamic Cone Penetrometer (DCP) testing determined optimal injection depths for URETEK Deep Injection® (UDI) using a surface grid pattern of approximately 4’x 4’. Taking these steps addressed the stability of the soils in each area that they would be injecting. Solution For the soil stabilization effort in Onondaga County, UDI was the perfect solution to stabilize the soils and bridge the weak area. URETEK drilled injection holes on 4’ centers as determined by the DCP. Crewmembers injected URETEK’s 486 Star® polymer through the tubes and into the soils beneath the base to fill the voids. The work area mainly included lanes and shoulders, creating a treatment area of approximately 2,000 sq. ft while minimalizing traffic closures. Laser instruments monitored the surface to ensure optimum soil stabilization. Result URETEK was able to stabilize the foundation soils and lift the asphalt roadway back to grade while at the same time staying under the NYSDOT budget limitations. Afterward, two other locations on both the west and east sides of Rt. 5 in need of repair were discovered. It was decided that this project will now be the first part of a three-year plan to completely stabilize the foundation soils where necessary along this section of the roadway. After an ongoing soil stabilization issue in Onondaga County, NY, URETEK ensured quick, efficient, and long-term repair provided at a fraction of both cost and labor. URETEK Deep Injection® (UDI) Widely referenced throughout our industry, UDI involves the injection of structural polymer into base and subgrade soils to increase the load bearing capacity. This is achieved by injecting the polymer through small holes drilled directly through the pavement structure to depths determined by site-specific analysis. Our URETEK 486 Star® material flows easily into voids and weak zones within the soil mass below. Through a controlled chemical reaction, the expanding polymer compacts surrounding soils and applies a controlled pressure on targeted areas of the affected pavement above. If needed, a multi-injection design plan is utilized to gently return the pavement to its original grade. The composite material quickly cures into a strong, dimensionally stable, and water-resistant geo-material, providing years of reliable service. URETEK 486 Star® URETEK 486 Star® polymer is a two-component, high-density, expanding thermoset polyurethane system. It was developed to be the ideal solution for under-sealing, void filling, lifting of settled pavement, stabilization and stiffening of weak soils, and for encapsulating and sealing buried infrastructure.
