» Assessment of existing Structures

Existing structures can require assessment for a variety of reasons: determination of maintenance and/or repair needs, signs of deterioration or overstress, and damage due to natural disasters. Our non-destructive visual assessments include documentation of existing conditions, determination of the causes of overstress or deterioration, and recommendations for repair or strengthening.

Restoration & Fiber-Reinforced Polymer Strengthening

» A Leader in FRP strengthening process

For more than 15 years, Cornerstone has been using this technology as a cost-effective solution for various applications. Glass fiber-reinforced polymers (GFRP) and carbon fiber-reinforced polymers (CFRP) are used in structural engineering for their notable strength and elasticity. The FRP method has been used by experts in the repair and rehabilitation of buildings and structural elements across every industry.

Trusted throughout the region as a source of expertise in the assessment and repair of existing structures, Cornerstone has long specialized in the use of fiber-reinforced polymers as effective, lightweight strengthening agents in damaged or compromised structures. Our expertise in this area is second to none.
