C-A- ? SIMPSON STRONG-TIE COMPANY INC Restoration Solutions Simpson Strong-Tie Anchoring and Fastening Systems for Concrete and Masonry Crack Injection Guide Important These instructions are intended as recommended guidelines Due to the variability of ?eld conditions selection of the proper material for the intended application and installation is the sole responsibility of the applicator Epoxy injection is an economical method of repairing non-moving cracks in concrete walls slabs columns and piers and is capable of restoring the concrete to its pre ? cracked strength Prior to doing any injection it is necessary to determine the cause of the crack If the source of cracking has not been determined and remedied the concrete may crack again Materials ? ETI-SLV for repair of hairline cracks and those up to in width ? ETI-LV for repair of ?ne to medium-width cracks Suggested width range ? ?? ? ETI-GV for repair of medium-width cracks Suggested width range ? ?? ? Crack-Pac injection epoxy for repair of ?ne to medium non-structural cracks Suggested width range ? ?? ? CIP-F and ETR are recommended for paste-over of crack surface and installation of injection ports ET-HP EDOT ETR or SET adhesives may also be used as a substitute SET is the only paste-over epoxy approved for NSF ANSI Standard ?

SIMPSON STRONG-TIE COMPANY INC Simpson Strong-Tie Anchoring and Fastening Systems for Concrete and Masonry Crack Injection Guide Preparation of the Crack for Injection Clean the crack and the surface surrounding it to allow the pasteover to bond to sound concrete At a minimum the surface to receive paste-over should be brushed with a wire brush Oil grease or other surface contaminant must be removed in order to allow the paste-over to bond properly Take care not to impact any debris into the crack during cleaning Using clean oil-free compressed air blow out the crack to remove any dust debris or standing water Best results will be obtained if the crack is dry at the time of injection If water is continually seeping from the crack the ow must be stopped in order for epoxy injection to yield a suitable repair Other materials such as polyurethane resins may be required to repair an actively leaking crack For many applications additional preparation is necessary in order to seal the crack Where a surfacing material has been removed using an acid or chemical solvent prepare the crack as follows Using clean compressed air blow out any remaining debris and liquid Remove residue by high-pressure washing or steam cleaning Blow any remaining water from the crack with clean compressed air If a coating sealant or paint has been applied to the
