We answer our most commonly asked question in our latest blog post. Find out how these two distinct CFRP fabric weaves are best utilized for common structural strengthening applications. In the two fabrics offered by SRS, the SRS-600UNI and SRS-660BI, the UNI is short for unidirectional and BI is short for bidirectional. Unidirectional carbon fiber means all of the fibers run in the same direction. In the case of the SRS-600UNI the weave consists of and aerial weight of 600

Increase the load capacity of structural wall openings
The use of carbon fiber for strengthening of the openings of new or existing concrete structures has become a widely used and common repair for this application. Concrete restoration contractors who specialize in these types of repairs often comment on the obvious advantages of CFRP vs traditional strengthening methods. The ultra thin profile of the reinforced composite can easily be installed around mechanical components that often prohibit traditional steel installations th

Flexural strengthening of beams for increased load capacity.
Structural strengthening of existing reinforced concrete structures to meet increased load capacity requirements has become a common application for CFRP and is one of the most effective materials for beam strengthening. In this case the SRS-600UNI serves as supplemental external reinforcement, resisting a portion of the tensile forces from the structure as higher load capacities were required in order to support modifications to the building.

Carbon Fiber Strengthening systems that can perform like a Swiss Army knife
When we set out to develop our roll kits, one of the objectives we had in mind was to provide contractors with systems that had utmost versatility in the field without compromise. Unidirectional and Bidirectional Carbon Fiber can solve a vast spectrum of repairs. Each roll kit is designed to perform in the most demanding of applications - from beam and flexural strengthening to bowed wall stabilization. It was imperative to us that contractors could confidently install SRS co

Bidirectional and Unidirectional Carbon Fiber working together
In this case, a combination of both bidirectional and unidirectional Carbon Fiber are being used to strengthen a block CMU wall. The SRS-660BI is used as a localized crack repair but also provides restraint between the vertical straps similar to a waler system. The SRS-660UNI vertical straps provide increased flexural strength over the entire height of the wall. #structuralstrengthening #structuralengineers #concreteconstruction #structuralengineering #concreterepair #concre

CFRP column wrapping for increased load carry capacity
Load carrying capacity can be increased by wrapping columns horizontally. The strength added is similar what you get from the spiral or hoop rebar typically included in these columns. If the design load is being increased or if there is section loss in the existing reinforcing steel, CFRP can be used to remedy this situation and help prevent a compressive failure in the column. Other possible solutions to handle such situations are to add a reinforced concrete jacket or addit

Carbon Fiber column confinement for increased flexural capacity
Unidirectional Carbon Fiber Reinforced Polymer (CFRP), is frequently used for increasing flexural capacity of reinforced concrete columns subjected to bending and compression As we all know, concrete is great in compression but lacks the tensile properties necessary for the demands so is usually poured with steel rebar embedded in it. This rebar provides the necessary tensile requirements so that the concrete can perform for the intended application. If this rebar is missing

What’s the difference in the SRS Carbon Fiber weaves? SRS-600UNI vs SRS-660BI
In the two fabrics offered by SRS, the SRS-600UNI and SRS-660BI, the UNI is short for unidirectional and BI is short for bidirectional. Unidirectional carbon fiber means all of the fibers run in the same direction. In the case of the SRS-600UNI the weave consists of and aerial weight of 600 grams of carbon fiber per square meter running the length of the roll. Bidirectional carbon fiber means that the fibers are running in two different directions. In the case of the SRS-66

Concrete Column Repair
SRS-660BI Carbon Fiber is commonly used to wrap support columns or other structural components, adding a tensile capacity of 35,496 lbs per 12” When a column is wrapped with a bidirectional carbon fiber not only is the confining/load bearing strength of the column increased, but also the flexural strength of the column itself. As the fabric wraps the column it must lap back onto itself in order to achieve the necessary bond capacity to act as a continuous wrap. #structural

Bowed Wall Stabilization using Unidirectional Carbon Fiber
Crossroads Foundation Repair was called out to a house in Brownsburg, Indianna to inspect a home where the basement walls were exhibiting some signs of horizontal and step cracking as well as bowing. Upon the completion of the inspection Kyle Leeman, Owner of Crossroads Foundation Repair, suggested the use of carbon fiber to reinforce the walls and prevent any further movement or damage. Kyle reached out to Structural Reinforcement Solutions, to obtain material for the repair
