Typical Installation Steps for Epoxy Grout • After the concrete is fully cured, chip the foundation down 19 mm - 25 mm using a light duty, hand held pneumatic chipper with a chisel type tool, removing all laitance and defective or weak concrete. • Chamfer all the foundation edges at a 45˚ angle, in order to remove stress concentration. • Remove all dust, dirt, chips, oil, water, and any other contaminants. • The final baseplate or soleplate elevation should allow 51 mm to 76 mm of grout between the surface of the foundation and the lower baseplate flange or the underside of the soleplate. • Fill the foundation anchor bolt sleeves with a non-bonding, pliable material, such as spray insulation foam to prevent the epoxy grout from filling the anchor bolt sleeve. Apply tape to the shanks and threads of all anchor bolts. • Build grout forms out of 18 mm thick plywood securely braced with 3.8 cm x 8.9 cm. Forms must be liquid-tight. Seal off any open spaces or cracks in forms, or at the joint between forms and the foundation using RTV sealant. Install 45˚chamfer strips along the top inside edges of the form at the final elevation of the grout as well as in all vertical corners. • Install expansion joints as required depending on the length of pour and specific grout chosen. • Coat the inside of the forms with three coats of paste wax on all areas that will come in contact with the grout to keep the grout from bonding to the forms. • Install and align the baseplate without any pumps or motors installed using jacking bolts. Jacking bolts should fall on round metal landing pads epoxied to the surface of the concrete. Apply a heavy coat of non-melt grease to the jacking screws so they can be removed later. www.chockfastgrout.com
Typical Installation Steps for Epoxy Grout • Mix the epoxy resin and hardener with a Jiffy Mixer for about three [3] minutes. Pour the mixed solution into a wheelbarrow, mortar box, or mechanical mortar mixer. • Slowly add aggregate to the mix one bag at a time. Mix the resin and aggregate only long enough to wet out all the aggregate. • Grouting should be continuous until all sections or compartments of the baseplate are completely filled. A head box can provide a hydraulic head to force the grout to the vent holes. • The use of a head box provides a surge volume for the grout, as well as provides the critical hydraulic head. • Tools and equipment can be cleaned with medium pressure water immediately upon completion. • Forms may be removed when the epoxy grout is adequately cured. This generally occurs in approximately 24 hours at 22˚ C when the surface becomes firm and not tacky to the touch. • The baseplate is to remain supported by the jack screws for 48 hours before removing them. The jack screw holes shall be filled with RTV or epoxy after being solvent cleaned to remove any bond breaker. The foundation anchor bolts can now be torqued. The frame shall be dial indicated at each anchor bolt and coupling, to determine any movement during torque. • Re-install the pumps and motors after the baseplate has been grouted and after the grout has cured for a minimum of twentyfour (24) hours.
