Any thoughts, comments, or hopeflly, product names. Thanks J.

Normally Ostend in detention facilities, their primary feature is that they are "pick proof", but the are extremely durable. Toy may also want to look at the stuff they use for highways and parking structures, Lyntal comes to mind.

Peter offers good advice; most state DOTs do extensive testing on highway coatings and sealants, and publish lists of acceptable products. ken hercenberg Senior Member Username: khercenberg Post Number: 617 Registered: 12-2006 Posted on Monday, October 07, 2013 - 01:34 pm:    Ralph, is the concern water migrating through the concrete or possibly protection of the substrate under the plates? In the past I used a very durable, waterproof concrete floor coating under steel plates subject to forklift or heavy truck traffic but the manufacturer went out of business (for other reasons). As Sheldon points out, most sealants that will be durable enough to withstand that type of abuse may not be able to handle the movement and deflection caused when the forklifts drive across the plates. If you'd like, I can see if I can find an equivalent product to the one I used to use.

It is a prefab freezer mounted on floor frame that sets on the main floor. Basically, a wood frame floor with sub-floor panels. The steel panels 1/4-inch thick are laid over the wood for the traffic load. It is those plates we need to seal. ken hercenberg Senior Member Username: khercenberg Post Number: 620 Registered: 12-2006 Posted on Tuesday, October 08, 2013 - 07:22 am:    If you have an idea as to how much movement and deflection you're dealing with, you might want to call the folks that Peter listed. If they can't help, you may want to check with a more traditional group like Tremco or Pecora and see what they still have in their bag of tricks.
