From: Joseph Murar <murarjm(--nospam--at)wwics.com> Subject: Slab on grade joint repair I need some information and ideas on repairing spalling at the construction and control joints in an existing concrete slab on grade. =20 The slab is about 7 years old and 6" thick 4000psi concrete with #4s @ 24" o/c E/W. The control joints are cut in 15 feet square to a depth of 1 =BD" deep and filled with an elastic joint filler.=20 Ever since the client switched from pneumatic tire to hard tire forklifts there has been noticeably cracking at the joints. The capacity of the old & new lifts and the loads they carry are identical.=20 Has anyone had this experience and what was the method of repair, did it hold after some months of being exposed to traffic? Also is there a reference were one can compare impact loading between pneumatic and solid tire lifts? Metzger/McGuire Co. makes a heavy duty joint filler for that type of application. They are in Concord NH (800) 223-6680 Roger Davis SDS Architects, Inc.
