Engineered FRP Systems for Structural Strengthening & Repair
Carbon and glass FRP systems engineers specify to strengthen beams, columns and slabs, and to restore corroded piles and seawalls, often without cofferdams, excavation or shutdowns.
Three systems carry most of our work: wet layup FRP for strengthening, SPiRe®+ panels for seawalls and beams, and PileMedic® for piles. Engineers specify them, contractors install them, and our team supports every project.
The advantage was that the broken pile could be repaired and reinstated up to the required bearing capacity and strength value, and no additional piles needed to be installed. This reduced cost and timing in repair method.

Hundreds of FRP technical papers, design guidelines and product data sheets, free for engineers specifying repair and strengthening projects.
What is FRP, and how does it strengthen a structure?
FRP (fiber reinforced polymer) is a composite of high-strength carbon or glass fibers embedded in an epoxy resin. Bonded to beams, columns, walls, piles and pipes, it restores or increases their strength without adding significant weight or size.
Can piles and seawalls be repaired underwater?
Yes. PileMedic® and SPiRe®+ systems are designed for underwater installation, so submerged piles, seawalls and bulkheads can often be repaired without cofferdams or dewatering.
Can pipelines be repaired without excavation?
In most cases, yes. PipeMedic® FRP repairs are typically trenchless, lining or strengthening water, sewer, gas and industrial pipes from 4 in. to over 180 in. in diameter from the inside with zero or minimal excavation.
Can you provide specifications and design details for our engineer?
Yes. Our team will recommend the right QuakeWrap® system and provide product data sheets, specifications and sample design details for your engineer of record.
Is FRP repair cheaper than replacing the structure?
In many cases, yes. FRP repair restores the existing structure in place, often without cofferdams, excavation or shutdowns, which avoids much of the cost and downtime of replacement.
