Backfill reinforcement employs precision, low-disruption ground improvement methods to enhance the performance of engineered fills supporting retaining walls, bridge abutments, wingwalls, culverts, and buried structures. Through controlled subsurface injection, specialized polymer or grout materials are distributed within the backfill to densify loose zones, bind granular soils, and fill hidden voids that can develop over time. This targeted treatment increases shear strength, improves lateral load resistance, and creates more uniform stress distribution along the structure–soil interface. By reducing differential movement and limiting water migration through the backfill, the process minimizes creep, rotation, and progressive settlement that can compromise structural alignment. Installation is typically performed from the surface with minimal disturbance to adjacent infrastructure or ongoing operations. The result is a more resilient backfill system that better supports structural loads, mitigates long-term deformation, and extends the service life of critical retaining systems while lowering future maintenance and repair risks and operational disruptions.
Below-Grade Structure Sealing
Below-grade structure sealing employs advanced, engineered barrier systems designed to prevent groundwater infiltration into underground facilities and foundations. These specialized sealing solutions are strategically installed to create a durable, impermeable boundary that protects concrete, masonry, and embedded infrastructure from water-related damage. By effectively blocking seepage pathways, the process helps mitigate corrosion, material degradation, and moisture-driven deterioration that can compromise structural integrity over time.
This method is particularly critical for foundations, tunnels, basements, vaults, and other subsurface structures that are continuously exposed to hydrostatic pressure and fluctuating groundwater levels. Beyond immediate protection, below-grade sealing enhances long-term performance by reducing maintenance needs, preserving structural stability, and extending service life. Additionally, it contributes to improved environmental control within underground spaces by minimizing dampness, mold growth, and water accumulation, ensuring safer and more resilient infrastructure.
Culvert Rehabilitation
Targeted injection and sealing technologies provide a trenchless approach to restoring aging, corroded, or structurally compromised culverts. Rather than relying on full excavation and replacement, engineered grouts, liners, and polymer systems are strategically applied to seal cracks, fill voids, and rebuild lost structural capacity from within the existing pipe. This process effectively halts groundwater infiltration, reduces erosion, and prevents soil migration that can undermine the surrounding roadway or embankment. By strengthening the culvert in place, the treatment improves load-bearing performance, enhances hydraulic efficiency, and protects against future deterioration caused by water, chemical exposure, or repeated traffic loading. Designed for rapid deployment, this rehabilitation method significantly reduces construction time, limits environmental disturbance, and minimizes traffic closures—allowing critical drainage infrastructure to be renewed, stabilized, and extended well beyond its original service life with long-term reliability.
Backfill Reinforcement
Cut-Off Wall Construction
Cut-off wall construction involves the installation of engineered, low-permeability subsurface barriers designed to effectively interrupt groundwater movement and manage seepage pathways. These barriers are formed through the controlled injection of specialized grout materials into the soil or rock, creating a continuous, impermeable zone that restricts water flow. By isolating groundwater, cut-off walls help prevent unwanted infiltration into excavations, foundations, and underground structures, reducing the risk of erosion, soil instability, and structural deterioration. This method is widely used in civil and geotechnical applications, including dam construction, levee reinforcement, retaining wall support, and environmental containment projects. In addition to controlling seepage, cut-off walls enhance overall site stability by minimizing hydrostatic pressure and mitigating the potential for slope failure or subsurface movement. Their trenchless installation process also limits surface disruption, making them a practical and efficient solution for protecting critical infrastructure, preserving soil integrity, and ensuring long-term performance in water-sensitive environments.
Deep Foundation Underpinning
Deep foundation underpinning is a precision ground improvement process designed to restore stability to structures affected by weak or shifting soils. Using engineered grouts, high-strength resins, and strategically placed reinforcement elements, technicians transfer structural loads to deeper, more competent strata while densifying and strengthening the surrounding ground. The treatment can be tailored to a wide range of conditions, including compressible clays, loose granular soils, and areas impacted by erosion or groundwater movement. By systematically rebuilding support from below, underpinning arrests ongoing settlement, re-levels compromised foundations, and reduces the risk of future displacement. The minimally invasive approach limits excavation, vibration, and disruption to building operations, utilities, and adjacent properties. Over time, deep underpinning enhances bearing capacity, improves structural alignment, and provides a durable, long-term solution that protects asset value, extends service life, and delivers reliable performance for residential, commercial, and industrial foundations across diverse geotechnical and environmental conditions around the world.

This system helps preserve the integrity of backfill, reduces differential settlement, and mitigates the risk of erosion-related failures over time. Designed to integrate seamlessly with conventional construction methods, trench breakers provide a durable, low-maintenance solution that improves long-term trench performance while protecting critical underground assets from water-related deterioration and structural instability.
Expansive Clay Mitigation
Expansive clay mitigation involves the strategic application of engineered ground improvement methods designed to counteract the damaging effects of moisture-sensitive soils. Expansive clays naturally swell when wet and shrink during dry conditions, creating cyclical ground movement that can place significant stress on foundations, slabs, and underground structures. Through targeted subsurface treatment, these soils are strengthened, densified, and stabilized to reduce their tendency to expand and contract over time. This process helps control differential movement, limit cracking, and prevent uneven settlement that can compromise structural performance. By addressing the root cause of soil instability rather than just the visible symptoms, expansive clay mitigation enhances load-bearing capacity, improves ground consistency, and provides a more predictable and durable subgrade. The result is increased foundation resilience, reduced maintenance needs, and greater long-term reliability for residential, commercial, and industrial structures built on problematic clay soils.
Groundwater Control
Effective groundwater control is essential for the stability, safety, and long-term performance of below-grade structures, foundations, and excavations. Using engineered grouting, resin injection, and advanced sealing systems, subsurface water pathways are strategically intercepted, contained, and redirected away from vulnerable assets. Low-viscosity permeation grouts migrate through granular soils to reduce permeability and form continuous underground barriers, while structural grouts seal cracks, joints, and construction interfaces that commonly act as leakage points. These integrated treatments decrease groundwater flow, relieve hydrostatic pressure acting on walls and slabs, and limit soil erosion or piping around buried infrastructure. By stabilizing moisture conditions in the surrounding ground, the approach reduces risks of uplift, settlement, corrosion, and material degradation. The result is a durable, minimally invasive solution that protects utilities, tunnels, retaining systems, and underground facilities, lowers maintenance demands, and supports reliable performance in challenging, water-sensitive environments.
MSE Wall Repair
Mechanically stabilized earth (MSE) walls can experience deformation, bulging, differential settlement, or loss of facing alignment over time due to poor drainage, foundation weakness, soil movement, or increased loading. To address these issues, targeted injection and structural reinforcement methods are deployed to re-establish stability from within the reinforced soil mass. High-strength polymers, grouts, or micro-piles are installed through the wall face or behind the reinforcement zone to densify weak soils, fill voids, and reconnect the wall to a competent bearing stratum. Supplemental tiebacks or anchors can be integrated where lateral support is insufficient. These minimally invasive, trenchless interventions limit excavation, reduce traffic disruptions, and protect adjacent utilities and infrastructure. The result is a restored internal reinforcement system that improves global stability, reduces outward movement, enhances load-bearing performance, and significantly extends the long-term durability and service life of the MSE wall.
