Grouting should not take place until after the specified curing period provided by the EOR.
Prior to grouting the PS=Ø couplers or joint, verify all of the materials have arrived on-site. Confirm condition of grout, size of joint, and usage of PS=Ø Closure Strip. Check the couplers for debris and water. Please be sure to review ACI Hot/Cold Weather Concrete Procedures.
Our grout has a working temperature range of 45° F to 90° F, avoid grout from freezing overnight. Grout has a shelf life of 12 months from date of manufacture, store in a cool, dry, indoor environment.
