Structural Evaluation & Diagnostics
Before any rehabilitation work begins, we must understand the true condition of the structure. Our structural evaluation services provide comprehensive assessment of infrastructure assets, enabling informed decision-making and targeted interventions. We conduct visual inspection to systematically assess visible distress including cracking, spalling, staining, and deformation. We employ advanced non-destructive testing techniques such as rebound hammer for concrete strength evaluation, ultrasonic pulse velocity for uniformity assessment, ground-penetrating radar for rebar location and cover depth, and half-cell potential for corrosion risk mapping. Our laboratory testing services include chloride content analysis, carbonation depth measurement, and petrographic examination. We perform load rating and capacity analysis to assess structural capacity against current and future loads, and durability studies to evaluate remaining service life and deterioration projections. For submerged structures, we conduct underwater inspection using divers or remotely operated vehicles to assess bridge piers and marine structures.
Concrete Rehabilitation & Repair
Concrete deterioration is one of the most common challenges facing aging infrastructure. Our concrete rehabilitation services address the full spectrum of deterioration mechanisms, restoring structural integrity and extending asset life. For bridge decks, we perform hydro-demolition to remove deteriorated concrete, apply repair mortar placement, install overlay systems, and implement corrosion mitigation strategies. For bridge piers and abutments, we conduct spall repair, concrete replacement, structural strengthening, and cathodic protection installation. For tunnel linings, we perform crack injection, concrete repair, waterproofing integration, and shotcrete application. For runways and pavements, we conduct joint repair, slab stabilization, overlay systems, and heavy-duty concrete repair. For marine structures, we perform tidal zone repair, pile rehabilitation, corrosion protection, and application of marine-grade repair mortars. Our concrete rehabilitation services restore structural capacity and safety, extend service life by decades, improve durability in aggressive environments, and provide a cost-effective alternative to replacement.
Waterproofing Systems
Water infiltration is a primary cause of infrastructure deterioration. Our waterproofing solutions protect critical assets against moisture ingress, ensuring long-term durability. For bridge decks, we provide liquid-applied membranes, sheet membranes, and traffic-bearing systems that withstand the constant pounding of vehicles while keeping water out. For tunnels, we offer sheet membranes, spray-applied membranes, crystalline systems, and injection grouting to create continuous, watertight barriers against hydrostatic pressure. For underground structures, we provide below-grade waterproofing, drainage systems, and protection boards that direct water away from foundations and prevent moisture intrusion. For expansion joints, we deliver preformed joint seals, injection systems, and custom flashings that accommodate structural movement while maintaining absolute watertight integrity. These systems ensure that water—the silent enemy of concrete structures—is kept at bay, protecting the reinforcement and concrete from the deterioration that moisture inevitably brings.
Cathodic Protection
Corrosion of reinforcing steel is the leading cause of concrete deterioration in infrastructure assets. Cathodic protection is the only proven technique that actively stops corrosion, regardless of chloride contamination or concrete condition. We offer impressed current cathodic protection for large structures such as bridges, tunnels, parking decks, and marine structures—systems that use an external power source to drive current through inert anodes to the reinforcing steel, providing adjustable, long-term protection. We also provide sacrificial anode systems for localized protection, repair zones, and smaller structures—maintenance-free systems that use more active metals that corrode preferentially to protect the steel. Discrete anode systems offer targeted protection for high-risk areas, while thermal-sprayed coatings provide large-area protection for steel and concrete structures. Cathodic protection stops active corrosion at the source, extends structural life by decades, reduces long-term maintenance costs, and protects the significant investments represented by infrastructure assets.
Soil Injection & Ground Stabilization
Infrastructure assets are only as strong as the ground beneath them. Soil injection and ground stabilization address foundation issues that threaten the stability and performance of bridges, roads, tunnels, and other structures. Our compaction grouting services densify loose soils and address settlement under bridge abutments and foundations. Permeation grouting fills pore spaces and improves soil strength for embankments and slopes. Chemical grouting provides rapid stabilization, void filling, and water flow control for urgent situations. Jet grouting creates soil-cement columns for deep foundation support where traditional methods are insufficient. Underpinning strengthens existing foundations for increased loads or when settlement has occurred. These techniques stabilize the ground, ensuring that the foundations supporting critical infrastructure remain stable and capable of carrying the loads placed upon them.
Structural Strengthening
As traffic loads increase and usage patterns evolve, infrastructure assets may require strengthening to meet new demands. Our structural strengthening solutions enhance capacity without the need for costly replacement. We offer fiber-reinforced polymer (FRP) wrapping for column strengthening, beam reinforcement, and slab upgrades—a lightweight, corrosion-resistant solution that adds significant capacity with minimal added weight. External post-tensioning strengthens bridge girders and enhances load capacity, using high-strength steel tendons to add active force to existing structures. Steel plate bonding provides structural reinforcement and flexural strengthening through bonded steel plates that increase section capacity. Section enlargement increases member dimensions and capacity by adding additional concrete and reinforcement. Carbon fiber reinforced polymer (CFRP) laminates strengthen bridge decks and girders, providing high-strength reinforcement in a thin, lightweight profile. These strengthening solutions extend the life of infrastructure assets, allowing them to meet the demands of growing populations and increasing traffic volumes.
Fire Protection Systems
Fire protection is essential for tunnels, airports, and other critical infrastructure assets where the consequences of fire can be catastrophic. Our fire protection systems are designed to detect and suppress fires quickly, protecting lives and assets. We provide fire alarm systems with addressable detection and notification for tunnels and transport facilities, ensuring early warning of any fire event. Sprinkler systems including wet pipe, dry pipe, and pre-action systems protect terminals and stations where fire risk is elevated. Special hazard systems such as foam systems for hydrocarbon fires and clean agent systems for sensitive areas address specific risks. Tunnel fire protection includes water mist systems that create a fine spray to absorb heat and suppress flames, fire-resistant linings that protect tunnel structures, and ventilation control systems that manage smoke and provide safe egress. Fire pumps and water supplies provide high-capacity fire water systems for large infrastructure, ensuring adequate water pressure and flow when it is needed most.
Restoration & Rehabilitation
Complete restoration services combine multiple protection and strengthening techniques to return aging infrastructure to optimal condition and extend service life. Our comprehensive bridge rehabilitation services include structural evaluation to assess condition, concrete repair to restore integrity, cathodic protection to control corrosion, waterproofing to prevent moisture intrusion, joint replacement to restore functionality, and bearing replacement to accommodate movement. Tunnel rehabilitation encompasses lining repair to restore structural capacity, waterproofing to prevent leakage, drainage improvement to manage water, and fire protection upgrades to enhance safety.
