How to install GeoTree Solution' RenewWrap FRP
FRPs (Fiber Reinforced Polymers) are composite materials made of a polymer reinforced with fibers. The polymer is usually an epoxy, vinylester or polyester thermosetting plastic that is combined with a fiber, such as glass or carbon, in order to make the polymer strong and stiff.
Currently, these polymers are used in almost every kind of advanced engineering, from aircraft to bridges.
GeoTree delivers a range of FRPs under its RenewWrap offering:
RenewWrap FRP
The RenewWrap FRP strengthening system comprises a wide range of carbon and glass FRP reinforcements and compatible saturating resins including our ICC-ES certified (ESR-3663) FRP strengthening system.
With hundreds of projects completed, RenewWrap FRP is a proven system in multiple applications including strengthening and seismic upgrade of buildings and structures, bridges, columns, caps, piers, and many other areas of need.
RenewWrap NSM CFRP Bars
RenewWrap pre-cured carbon fiber bars are designed to be used in near surface mounted (NSM) strengthening applications. RenewWrap carbon fiber bars are manufactured with a grit surface to promote adhesion with the bonding resin.
RenewWrap NSM CFRP Bars may be used to strengthen or retrofit a wide range of concrete and masonry structures. They are most commonly used where traditional wet lay-up FRP systems are not suitable or where the FRP reinforcement requires additional protection from abrasion or vehicular traffic.
NSM bars are used for strengthening existing structural members (concrete, wood, stone, or masonry) in flexure and shear. Structures that are deficient due to either a structural flaw, deterioration or a change in use, can often be brought to useful capacity using NSM bars.
RenewWrap Strand Sheet
RenewWrap Strand Sheets are unidirectional reinforcement sheets consisting of an assembly of pre-cured carbon fiber micro bars. Sheets are externally bonded to existing steel, concrete, and masonry structures to enhance their strength and stiffness. Strand Sheets combine the best features of traditional wet lay-up fabric and pre-cured plate FRP system creating a cost effective method for strengthening steel structures.
