When manufacturing equipment needs to be anchored to the shop floor, bolts are set at predetermined locations recommended by the equipment manufacturer. EPS (expanded polystyrene) blocks are typically used as block-outs at the bolt locations when the concrete slab is poured. The EPS block-outs can be installed with or without the bolts in place. For this project in Ephrata, Pennsylvania, the contractor was able to use 4” x 8” x 15” blocks of .9lb recycled EPS to secure the bolts in place prior to pouring the slab. Once the concrete sets up the EPS is removed and grout installed in the remaining opening, securing the bolts in place. This same process is also used to secure awnings and walkway covers to sidewalks and concrete patios.
