Your Full-Solution Partner for Composite Strengthening Systems™

Simpson Strong-Tie Composite Strengthening Systems (CSS) provide efficient solutions for the structural reinforcement and retrofit of aging, damaged or overloaded concrete, masonry, steel and timber structures. The primary benefit of Composite Strengthening Systems versus traditional retrofit methods is that significant flexural, axial or shear strength gains can be realized with an easy-to-apply composite that does not add significant weight or mass to the structure. Many times it is the most economical choice given the reduced prep and labor costs and may be installed without taking the structure out of service.

Two Solutions for your CSS Projects

FRP – Fiber-Reinforced Polymer

For the structural reinforcement of concrete, masonry steel and timber elements we provide corrosion-resistant and high-performance FRP products including carbon fiber (CFRP) and e-glass fabrics, North America’s first code-listed pre-cured laminates and FRP anchors. The primary benefit of FRP systems versus traditional retrofit methods is that significant flexural, axial or shear strength gains can be realized with an easy-to-apply composite that does not add significant weight or mass to the structure.

FRCM – Fabric-Reinforced Cementitious Matrix

The new FRCM Composite Strengthening System combines high-performance sprayable mortar with a carbon-fiber grid to create thin-walled, reinforced concrete shells without adding significant weight or mass to the structure. Its advantages are similar to those of FRP (that is, strength, low weight, and ease of application), but also that it may be applied to repair and resurface, strengthen and protect in one application, as well as greater resistance to heat and better long-term durability.
