Applied Liquid Polymer Systems, Inc has been in the business for a while now.
We specialize in epoxy injection of structural-strength low-viscosity epoxy resins for bonding of cracked, delaminated, and spalled concrete. This process also works extremely wellh2 in repairing damaged wood members, such as glue-lam beams and wood trusses.
We also repair spalled concrete using high-strength polymer-modified mortars, provide placement of machine-based grouts, and applications of CIM specialty liquid-applied waterproof membrane materials.
Whether your needs are Commercial, Residential or Industrial, we have years of experience in the application of epoxy and urethane coatings and look forward to helping you with your foundation, wall, floor or driveway repair or restoration.

Structural Concrete Bonding Process™
Most engineers agree that it is the natural for concrete structures to crack to a minor and major degrees. Concrete cracking indicates that the structure has been forced to absorb the energy of some form of over-stressing. Concrete cracking is caused by:
- Concrete shrinkage during cure, before the concrete has developed full strength.
- Mechanical overload, either static or dynamic.
- Temperature changes in a concrete structure where no provision was made for movement or controlled cracking.
- Base or foundation settlement that most often is limited and ceases after a certain period of time.
Concrete Cracks can be repaired
However, when a concrete structure has cracked for any of those basic reasons, it does not necessarily mean that the structure has failed. On the contrary, any cracked concrete structure can be repaired effectively and most often permanently, provided the structure has not been wholly deformed and the original cause of cracking has stopped. Since 1959, the most effective method of repairing cracks in concrete has been the Structural Concrete Bonding Process, developed by Adhesive Engineering Company, San Carlos, California.
The SCB Process
The SCB Process is a proprietary method of injecting fissures down to 0.002 inches wide for their full depth with a high strength epoxy resin adhesive. When the injected adhesive cures, it seals the crack entirely and also restores the concrete to its original monolithic condition. Injecting repairable cracks in concrete will satisfactorily:
- Restore structural and/or design strength to the cracked concrete structure.
- Eliminate serious spalling of concrete initiated by cracking and aggravated by freeze thaw cycling.
- Prevent corrosion of reinforcing steel and pre-stressing tendons by encapsulating them against moisture or water contact.
- Stop the leakage of water and fluids through concrete structures than can result in contamination or damage to the rest of the structure and expensive equipment and machinery.
- Repair concrete architecturally without any of the unsightly surface marks caused by standard surface crack repairs.
In the past 55 years the SCB Process has been employed worldwide by certified applicators to repair thousands of cracked concrete structures with considerable cost savings compared with conventional repair methods. Those savings were realized because the SCB Process allows repair of cracks in the shortest possible time, thus minimizing downtime. Frequently, repairs can be made without taking a structure out of service.
How SCB Process works
The SCB Process is proprietary and available only through licensed applicators. The following description is essentially an overview:
A temporary seal is applied to the crack face and entry ports are placed in the seal along the crack plane. If the crack extends entirely through the concrete, where possible, the back side is also sealed to prevent adhesive run out.
Two metering pumps drive the two components (resin and hardener] of a fast-setting epoxy adhesive to a special mixing head. The adhesive is mixed at the nozzle and injected through a special gasket that prevents leakage on the face of the concrete.
The adhesive is pumped into the first entry port until it begins to show at the next adjacent port. The operator knows that the adhesive has reached the full depth of the concrete member when the adhesive oozes out of the next port.
The first injected port is then plugged and injection is resumed at the second port. This procedure is followed until the entire crack or void in the concrete is filled. The procedure is the same on horizontal or vertical surfaces. On vertical members the first port injected is usually the lowest and injection progresses upward. Injection pressures range from 2 psi to 200 psi and are controlled by the operator.
After the epoxy adhesive has cured, the temporary surface seal is removed, leaving the face of the concrete smooth and unmarred except for the faint trace outline of the crack. Sacking or painting usually will hide the injected cracks completely.
A wide range of structural applications
- Pre-cast concrete members are joined in place by simple injection of high strength structural adhesive. Wide joints or keys are pre-packed with aggregate.
- Machinery is grouted with non-shrinking, high-strength adhesive after leveling. Large voids are pre-packed with aggregate. Injection assures 100% load bearing on grout bed.
- Cracks and de-lamination in concrete warehouse floors are re-bonded through injection of epoxy adhesive.
- De-laminated Glu-Lam Beams are re-bonded in place, avoiding costly replacement.
- Rock pockets are filled with high-strength structural adhesive avoiding costly demolition and replacement.
- Bolts from fixabolt and other anchors are grouted in place with structural adhesive, thus avoiding air pockets.
For earthquake damage
Nothing more typifies the maximum effectiveness of the SCB Process than the role it has played in restoring concrete structures damaged by earthquakes. Without the high strength, economical repairs made possible only by epoxy injection, scores of buildings would have been scrapped and rebuilt.
