Simply the Strongest Straps
BowGuard delivers class leading strength of commercial grade SRS-600 Unidirectional carbon fiber and ultra high strength structural epoxy to form the strongest composite bowed wall strap available.
Combined with the ICC-approved Simpson Strong-Tie® Universal Retrofit Foundation Plate* with inset sill plate flexibility, and SRS-1000 Epoxy Slab Lock, these components form a continuous load-transfer path from the sill plate to beneath the slab — delivering faster, cleaner, and stronger top-to-bottom stabilization than any other system on the market.
Seamless Stabilization
Now Available with Seismic-Certified Protection
ICC-approved Simpson Strong-Tie URFP bracket delivers engineered, earthquake-rated anchorage—a level of structural reliability unmatched in typical bowed-wall systems.

Class Leading Strength with Commercial Grade Carbon Fiber
600 gsm Uni-Directional Carbon Fiber Fabric Designed to Perform Under Pressure
SRS Carbon Fiber Composite Straps permanently secure and stabilize the basement wall against any further inward movement. The industrial strength adhesive epoxy penetrates deep into the pores of the concrete, while saturating the carbon fiber providing a permanent bond to the foundation.The SRS-600UNI composite straps exhibit a design tensile strength of over 39,000 lbs to permanently stop inward movement related to the external soil pressure.
The SRS-600UNI straps spaced at 4’ on center on an 8” cmu wall will provide over a 3X safety factor to resist the pressures from standard soils weighing around 100 pounds per cubic foot.
Even as soil properties change, this safety factor allows room for variations to ensure that a proper safety factor is achieved. We limit the spacing to 4’ on center per the requirements of the standard masonry reinforcement codes.
The Strongest Base Connection in the Industry
The SlabLock Epoxy Shear-Guard Connection creates a seamless, monolithic bond between the wall and slab—something other bowed-wall systems simply can’t match. Formed with SRS-1000 structural epoxy, this detail encapsulates the carbon fiber within an anchored block of cured resin that mechanically locks the strap to both the concrete wall and slab edge.
By eliminating extra anchors, brackets, and hardware, the SRS-1000 SlabLock connection delivers a cleaner appearance, faster installation, and a stronger, continuous load path at the base of the wall. It forms a fully integrated structural connection engineered for long-term stability and proven performance.
Tested to ASTM C881 and AASHTO M235,
SRS-1000 provides verified reliability in demanding conditions, giving contractors, engineers, and homeowners complete confidence in every installation.

Engineered for maximum safety & reliability
SRS's advanced composite strengthening system provides additional tensile capacity on the inside face of bowing walls in order to resist the external soil pressures on the wall. If the wall is constructed properly with the sill plate properly tied into the top of the wall as well as anchored to the house framing, then the use of the externally bonded reinforcement is often all that is needed to provide additional resistance to stop the inward movement of bowing walls.
High performance carbon fiber fabrics require high performance adhesives
SRS bowed wall straps use 6" wide, 600 gsm unidirectional carbon fiber engineered specifically for structural wall reinforcement. When combined with our structural epoxy, the system forms a high-strength composite providing 196,000+ PSI tensile capacity. This allows contractors to stabilize CMU or poured walls with a permanent, low-profile solution that integrates cleanly into finishing systems.
The epoxy is mixed at a 2:1 ratio and is available in three different formats:16 oz and 33 oz cartridges and three-gallon bulk kits.
Three Modes of Structural Defense
Why do CMU walls fail?
Block, CMU, or concrete walls fail for a number of reasons from lack of reinforcing steel to excessive loads due to expansive soils or excess ground water. When shearing at the base is a concern, contractors have a couple of options. They can use the standard practice of adding grout filled reinforced cores at the base. If the slab is being removed for a waterproofing system, they can run the bowed wall straps all the way down to the footer before pouring the wall back. These straps can even be anchored to the footer or in cases where the floor is not being removed, small sections can be removed at each strap location to achieve the same result.
When the wall is not constructed properly
If there is a concern with the walls tipping, there are several options to address this. Firstly and most commonly, the contractor should ensure there is an adequate connections between the house framing and the top of the wall. In cases where additional resistance needs to be provide, top connections connecting the bowed wall straps to the house framing can be added. Blocking or angles can be used to provide additional shear resistance as well. In cases where the bow/opened mortar joints are high on the wall, these top connections in additional to the SRS-660 Bidirectional Carbon Fiber reinforcement across the top of the wall can be used.
In cases where the walls are not constructed properly and tied in at the top or where shearing or danger of shearing at the base is present, we have additional solutions that can be incorporated into the system to ensure that the walls are properly stabilized.
It's important to ensure that you have the right components and design for your specific application. SRS 600-UNI BowGuard provides the flexibility required to deal with shear stress at the base of the wall.
SRS has you Covered With the Most Advanced Rapid Cure Repair Paste Available
Why void filling is an important step before any carbon fiber installation
Since carbon fiber needs to remain in contact with the wall in order to remain in tension, it is important to fill the 'hinge point' where the wall opens up on this mortar joint. This important step prevents the wall from receding backwards and potentially de-bonding the carbon fiber. Any voids, cracks, or mortar joints should also be filled with this high compressive strength, non-sag 2100 Repair Paste.
