Trash Transfer Station

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I’m in the process of putting together some bid documents for the repair of a severely eroded framed slab at a trash transfer station. We will be milling the top of the concrete down and going back with a mineral aggregate topping (L&M Emerytop 400) of 1½ to 2 inches in thickness.


The material supplier has recommended that we provide control joints at least 12 feet on center in the topping and I am concerned about the durability of any sealant we fill the CJ with.  In addition, I am debating whether a tooled CJ or a sawn CJ would be less susceptible to the wear and tear environment of the trash tipping floor.


Any input would be appreciated.
