We stopped the leaks in this storm sewer culvert with urethane injection, which forms expansive, closed cell foams when it contacts water and then adheres to the concrete surfaces. Our urethane injection provides a permanent repair.


Chloride contaminated and carbonated concrete had threatened the structural integrity of this beach house.The support columns were restored to a better than new condition.


Renovation of a settling historic home required injection of soil stabilizer to a depth of four feet below the existing footer. The stabilizer binds together loose soils and provides tremendous compressive strength. This system is inert when cured, is non-hazardous, and will not pollute. The soil is stabilized, therefore the structure is stable.


To all parties involved, this job appeared impossible at first, second and third glance. There was excessive vibration in the walkways in an aeration tank—the only aeration tank in the system—it could not be taken out of service. The engineers had determined that the column bases had degraded and were no longer properly secured. Our job was to repair and expand the column bases that were twelve feet deep in wastewater. We were in deep but through the resourcefulness of our entire group, everyone, including the customer, came out smelling like a rose.


An overhead Double T beam exhibited stress cracking. Carbon Fiber Reinforcing was specified to restore structural integrity. Although access was difficult, infrared testing indicated that the carbon fiber strips were well bonded. The alternative to restoration was replacing the beam—Carbon Fiber Reinforcing was the least expensive, structural remedy.
