Recommendations Install Jay R. Smith Mfg. Co. Enviro-Flo® Drainage Systems in strict accordance with manufacturer's recommendations and shop drawings. Excavate the area for channel placement wide and deep enough to accommodate the standard channel size and a minimum of 4" concrete encasement on both sides as well as underneath the channels. Channels require a minimum of 4" of support and the top of the grate must be evenly aligned with the surface of the surrounding slab. (Note: The thickness of the concrete encasement must be at least as thick as the slab and never less than 4"). |
Installation Channel sections are installed from the outlet end of the system working from either catch basins or large numbers to small numbers. Insert channels from above to allow ends to interlock. Channel sections shall be installed using manufacturer’s recommended installation device to maintain a minimum of 4" thickness of concrete below the channel system, or suspended to obtain correct finished elevation. Cutting will be made if required by installer. During concrete pour, leave plywood in channels to avoid compression and to keep debris out. |
Concrete Placement Protect grates and channel interior during pouring of concrete. Place concrete in a manner that will not dislodge the channels. Concrete shall be at finished level or 1/8" above the top of the channel to ensure efficient drainage and adequate channel edge protection. |
Finishing and Clean-up Following final set of concrete, remove grate protection, place grates in final position and engage locking bolts in correct location. |

Channel Joint Sealing Requirements Heat welding is required to seal channel joint connections for all chemicals listed on the Enviro-Flo® Systems Chemical Resistance Guidelines unless a ** is shown next to the chemical. Chemicals listed with a ** can also be sealed by using Chem-Caulk 900 sealant manufactured by Bostic. |
