1 ITW PO LYME R TE CH N OL OGIES130 Commerce Drive Montgomeryville, PA 18936 215-855-8450 Fax Bulletin #1600 BBulletinDescriptionThe following Grout Installation instructions apply to standard ESCOWELD Epoxy Grout applications onconcrete foundations where the Grout thickness is within the specified range. Outside this range, pleaseconsult your CHOCKFAST distributor for ListThe following materials are required to effectively install ESCOWELD epoxy Grout . Assemble allmaterials prior to starting any supply ofESCOWELD 7505E/7530 Epoxy Grout . We recommend ordering 10% to15% extra to account for spillage, waste, on location of covering for floors and compressor, hoses, chipping gun and auxiliary masks, goggles, hard hats, rubber gloves and ear check with on-site safetypersonnel for safety equipment vacuum anchor bolts if equipment, ventilation equipment if or split hoses for isolating anchor bolts from materials: lumber,Styrofoam,chamfer strips, nails, putty, weather stripping, paste waxand carpenters mixing equipment.

2 Wheelbarrows, mortar hoes and buckets or mechanical mortar mixer soapy water or clean-up solvent and rags for clean up adequate number of people to help mix and install the the foundation to successfully absorb vibration from the equipment there must be a solid connectionfrom the equipment down through the baseplate and foundation and into the soil underneath. Thisrequires a solid connection between the epoxy Grout and the baseplate as well as the epoxy Grout andtheconcrete foundation. The recommendations below are provided to help ensure this connection surfaces to be in contact with the ESCOWELD7505E/7530 Epoxy Grout should be dry andfreeof grease, paint and rust for optimum bonding.

3 A bright metal surface can be obtained bysandblasting or grinding. In high humidity areas, equipment should be grouted immediately aftersandblasting or grinding. If immediate grouting is not practical, these surfaces should be protectedwith a thin coat of ITW Rust Inhibitive on which the Grout will bear should have attained its design strength and shrinkage beforegrouting. The design strength, curing information and shrinkage information is available from theconcrete supplier. All concrete surfaces that are to come into contact with ESCOWELD 7505E/7530 Epoxy Grout should be chipped approximately 1 inch in depth to removelaitanceand provide arough surface for good bonding and shear strength.

4 If concrete is oil soaked, chip away concreteuntil oil or contaminants are removed. Only sound concrete is shims, leveling screws, wedges and blocks that will eventually be removed from the installationshould be covered with putty or wax prior to pouring ESCOWELD 7505E17530 Epoxy 7505E/7530 Grout InstallationProcedure for Installing Heavy EquipmentESCOWELD 7505E/7530 Grout InstallationBulletin No. 1600B, Page2 Rail / Soleplate Installation6"6"2" " " around anchor bolts completelywith ESCCWELD 7505E/7530 EpoxyGrout restricts the spring effect capabilitiesof the full length of the bolt and should beavoided as bolt sleeves should be packedwith foam rubber, spray urethanefoam, asphalt or other bolts should be wrapped toprovideabarrierbetweentheESCOWELD7505E /7530 EpoxyGrout and the anchor to contain the epoxy Grout are typically made from inchplywood and 2x4 s and 2x6 s.

5 Thefollowing are some recommendations to improve the quality of the embedded machines, forms tocontain ESCOWELD 7505E/7530 Epoxy Grout should be designedto provide a Grout level of one-inch minimum above the engineframe bottom and to chamfer theoutside edge of the Grout . For railor soleplate mounted machines,forms shall be designed to providea Grout level of inch minimumbelow the top of the rails should be liquid tight topreventlossof epoxy groutmaterials. Any open spaces orcracks in forms at the joints orbetween forms and the foundationblock should be sealed off usingputty or duct form material should be coatedwith 3 coats of heavy paste wax onall areas that will come into contactwithESCOWELD7505E/7530 Epoxy Grout to prevent engines having a V-shaped oilpan, a seal may be made using awaxed or polyethylene wrapped firehose to prevent the Grout fromleaking under the crankcase.

7 The expansion joint shouldbe 1/2 to 1 thick. It is very important that the expansion joint material bonds to the Grout so that itdoes not provide a path to the concrete for oil, water and other contaminants. In deeper pours closedcell foam can be bonded to thin wooden bracing material and tacked into the base of the form. Thetop of the foam expansion joint should be level with the finished surface of the Grout .

The gaps then may befilled with ITW Expansion Joint Compound. This will prevent oil penetration to the concrete. It issuggested that expansion joints be placed so that they isolate each soleplate or rail.

9 In full bedapplications, expansion joints should be placed every 4-6 or reinforcing bars or rods can improve the overall strength and soundness of a groutedfoundation. The following recommendations will improve the effectiveness of the pouring deep or long pours, steel-reinforcing bars may be used to minimize stress distribute the stresses under these conditions, #4, or #5 rebar should be placed at 12-18 centersparallel to the rebar should be placed approximately 2 below the Grout surface and if the rebar is tiered, thebottom rebar should be located 2 above the foundation on the ESCOWELD packaging labels relating to safety precautions in handlingESCOWELD 7505E/7530 material components should be closely unit consists of.
