An upcoming NCFI webinar will address common engineering concerns about polyurethane injection, including project suitability, risk management, and specifications. […]
Polyurethane is one of those technologies that seems simple on the surface. Drill, inject, lift. Done. But the performance really comes down to how it reacts in the ground and how it interacts with the […]
Coal handling facilities are tough environments for concrete, especially when long-term water intrusion begins to undermine operations below grade. In this NCFI case study, a coal terminal was dealing with persistent underground leaks in a […]
The reuse of existing foundations can offer significant schedule, cost, and sustainability benefits on large renovation projects, but it also introduces geotechnical challenges that are not always straightforward to address. One such challenge is how […]
SlabJack Geotechnical recently tackled a challenging project in Everett, Washington, where a two-year-old tilt-up panel building faced serious subsidence issues. The building, which featured a 30-foot fill CMU block retaining wall, had settled by 2.5 […]
HOUSTON, TX— As part of the New Jersey Turnpike Authority’s (NJTA) $1 Billion Capital Projects Campaign “to boost mobility and improve safety for generations to come,” box culverts are suddenly big business. “Most people take […]
Two recent projects using TerraThane™ geotechnical polyurethane grout were successful in solving seepage problems. TerraThane™ is a two-part geotechnical polymer that when mixed at the injection location, expands to many times its initial volume and […]
Problem There’s an old saying, “If you have a 14′ stormwater drain that has some severe voids behind it, then you’re asking for trouble if you don’t fix it!” That’s not actually an old saying, […]
When culverts, storm drains, and manholes age or settle, joints that once were tight begin to open up. When that happens, water and soil can migrate through these cracks, termed inflow and infiltration (I&I). It […]
This is a great application of polyurethane grouting, to fill voids and stabilize soil behind a seawall at the Port of Los Angeles. Check out the video below from EagleLIFT.
