Spreading paste-over into a thin film (approximately 1/8") on the mixing surface will slow curing by allowing the heat from the reaction to dissipate. Note: CIP-LO and ETR are a fast cure and when manually mixed may harden prematurely if left in a mixed mass on the mixing surface while installing ports. As a rule of thumb, injection ports should be placed 8" apart along the length of the crack.Īllow the paste-over to harden before beginning injection.

Place the port at one end of the crack and repeat until the entire crack is ported. To adhere the port to the concrete, apply a small amount of paste-over around the bottom of the port base. Sealing of the Crack and Attachment of E-Z-Click™ Injection Ports If the surface coating is covering the crack, it may be necessary to route out the opening of the crack in a “V” shape using a grinder in order to get past the surface contamination. Under the pressure of injection, these materials may lift and cause a leak.
If a coating, sealant or paint has been applied to the concrete, it must be removed before placing the paste-over epoxy.
Blow any remaining water from the crack with clean compressed air. Remove residue by high-pressure washing or steam cleaning. Using clean, compressed air, blow out any remaining debris and liquid. Where a surfacing material has been removed using an acid or chemical solvent, prepare the crack as follows: Other materials such as polyurethane resins may be required to repair an actively leaking crack.įor many applications, additional preparation is necessary in order to seal the crack. If water is continually seeping from the crack, the flow must be stopped in order for epoxy injection to yield a suitable repair. 
Best results will be obtained if the crack is dry at the time of injection. Using clean, oil-free compressed air, blow out the crack to remove any dust, debris or standing water. Take care not to impact any debris into the crack during cleaning. Oil, grease or other surface contaminant must be removed in order to allow the paste-over to bond properly. At a minimum, the surface to receive paste-over should be brushed with a wire brush.

CIP-LO, CIP-F and ETR are recommended for paste-over of crack surface and installation of injection ports. Crack-Pac Flex-H2O polyurethane crack sealer for repair of fine- to medium-width cracks (suggested width range: 1⁄32"–1/4"). Crack-Pac® injection epoxy for repair of fine to medium non-structural cracks (suggested width range: 1/64"–1⁄4. CI-GV for repair of medium-width cracks (suggested width range: 3⁄32"–1⁄4"). CI-LV FS and CI-LPL for repair of fine to medium-width cracks (suggested width range: 1/64"–1⁄4. CI-LV and CI-SLV for repair of hairline cracks (0.002") and those up to 1⁄4" in width. If the source of cracking has not been determined and remedied, the concrete may crack again. Prior to doing any injection it is necessary to determine the cause of the crack. Due to the variability of field conditions, selection of the proper material for the intended application and installation is the sole responsibility of the applicator.Įpoxy 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.
