09: LIMITATIONS
Surface must be clean and sound. It may be dry or damp, but free of standing water and frost. Remove a light layer of concrete from the surface work
areas. Consult the current product data sheets for DRICORE™ PRO Concrete Repair Unidirectional Carbon Fiber for additional information on surface
preparation.
Existing uneven surfaces must be filled with an appropriate repair mortar/hydraulic cement. The adhesive strength of the concrete must be verified, after
surface preparation, by random pull-off testing (ASTM D-4541) at the discretion of the engineer. Minimum tensile strength, 200 psi (1.4 MPa) with
concrete substrate failure.
Preparation Work: Concrete - Blast clean, shotblast or use other approved mechanical means to provide a roughened, open-textured surface.
Round all corners to 1/2” radius in certain “contact critical” applications and at the engineers discretion, a thorough cleaning of the substrate using low
pressure sand or water blasting may be sufficient.
Application prior to placing the fabric, scarify the concrete surface using a dustless grinding system. The fabric may also be manually saturated
using your hand, a roller prior or scraper to placement. In either case, installation of this system should be performed only by a trained contractor. In
fiber direction, overlapping of the fabric must be at least 10mm or as per the project specifications. Overlapping sections of additional layers should
be distributed over the column circumference.
Fabric can be cut to appropriate lengths by using scissors. Since the dull or worn cutting implements can damage, weaken or fray the fabric, their use
should be avoided.
•Design calculations must be made and certified by an independent licensed professional engineer.
•System is a vapor barrier. Concrete should not be fully encapsulated in areas of freeze/thaw.
