Z886 PERMA-TRENCHINSTALLATION INSTRUCTIONSZ886 EncasementA 4" [102] new concrete encasement is minimum. Guidelinesfor reinforcing an encasement would be to use the samethick-ness and reinforcing used in the surrounding concreteslab. Concrete must be vibrated to remove air voids inencasement, especially under the frame rails.Specifying engineer is responsible for concrete encasementand reinforcing based upon application and local codes.ExcavationTrench excavation must include the minimum of 4" [102] onboth sides and underneath or the slab thickness surroundingthe trench. Soft and/or shifting soil substrates may causecracking of the concrete and consequent movement ofthe trench. It is critical that the concrete be poured on anadequate foundation. Verify depth of trench excavation toallow for the same thickness of concrete under and besidethe trench as the surrounding slab thickness.44 [102]MIN.6-1/4 [159]4 [102]INVERT1-1/4 [32]4 [102]MIN.

Z886 PERMA-TRENCHINSTALLATION INSTRUCTIONSZ886 LayoutUpon completion of the excavation, the channel shouldbe placed in numeric order alongside the excavationaccording to the job layout. Each trench section has a trenchidentification number and flow direction indicating itssequence within the system. It is best to work from the deepor outlet end to the shallow. Grates are not installed at thistime.Four (4) shipping/installation bars per channel;recommended spacing is approximately 3"-6" [76-152] fromend of rail for end pieces and 26"-29" [660-737] from end ofrail for center pieces. All shipping/installation bar locationsare approximate.Must be installed onchannels without HDor HDS framesFemale End5

This ensures each trenchwill have a grate on it.6Scrap

Z886 PERMA-TRENCHINSTALLATION INSTRUCTIONSZ886 Connecting theTrench with Sidewalls1When using sidewalls with a joint connector, be sure tokeep the trimmed pieces to attach to the sidewall portionof the trench using the hardware provided.Z886 Connectingthe Trench2 Attach to the channels with the hardware provided.Non-HD FrameChannels should be installed from deep or outlet endto shallow end. This allows the next shallower channel’smale connection to easily set onto the previous channellip. Stake in place with No. 4 rebar (by others) and attachwith the provided connection hardware.SEALING Channel connections are designed to be a good seal,meaning concrete aggregate will not intrude intothe trench. Silicone sealant may be used as a gasket between thechannels for a better seal. Channel connections may be welded with an HDPEwelding gun for the best seal.CONNECTIONS The maximum gap between frames is 1/4" [6].Rebar length dictated by trench depth and substrate for positiveanchoring while setting to resist floating.10HD Frame

This should be done for all sizes of basins.Scrap2 Cutting the hole in the basin can be easily accomplishedwith the use of a hand saw or power reciprocating saw.Cut out the material inside of the traced area, includingthe upper lip under the frame. Do not cut the frame.Scrap3 After the channel outline is removed from the catch basin,cut the inlet adapter to the height of the hole in the basin.Secure the inlet adapter to the basin using the hardwareprovided. Be sure to use silicone caulk or constructionadhesive to seal the adapter to the basin.4 Slide the male end of the channel into the inlet adapter,attaching them together with the supplied hardware andsilicone caulk or construction adhesive.11

Z886 PERMA-TRENCHINSTALLATION INSTRUCTIONSZ886Setting the TrenchNEW CONSTRUCTIONTypically, a trench system is assembled from the outlet back.Starting with the deepest section or catch basin, set the firstchannel utilizing the integral rebar clip anchoring system.Rebar clips are on both sides of each trench drain for easyattachment to No. 4 rebar stakes. Slide the rebar into therebar clips. Then drive the stakes into the ground for positiveanchoring. Secure the trench to the rebar stakes with thehardware provided with bag No. 841.Adjust the trench to the desired elevation and repeat theprocess with the next channel.14Set trench on rebar 1" [25] above final grade — this allowsfinal elevation adjustment with a hammer prior to pouringconcrete.It is recommended to pour concrete the same day the trenchis set.Recess trench 1/8" [3] below finish grade to ensure positiveflow into trench grate.

Z886 PERMA-TRENCHINSTALLATION INSTRUCTIONSZ886 ConcretePour and FinishRemove shipping/installationbars as you finish trowelingPour the concrete around the three sides of the trenchdrain. Be certain to adequately vibrate the concrete asit is being placed. Proper vibration will eliminate anyunwanted voids within the concrete pour. If sidewallsare used, a first and second pour are recommended.Verify layout is correct prior to pouring concrete.PLACING CONCRETE Adhere to check that the trench drain is in thelocation required per the layout drawings prior topouring concrete. Standard concrete practices with expansion andcrack induction joints shall be followed based uponlocal codes and standards. The trench drain shall not be used as anexpansion joint.75" [19]5.5" [140]The use of nominal 1x6 (3/4" x 5-1/2") [20 x 140] lumber supplied byothers may be used to keep channel clear during the concrete pour.Finish troweling should be done to set the top edge of thetrench drain 1/8" [3] below the floor grade. Remember tocompensate for the concrete shrink that may occur duringcure so that the edge of the trench drain does not protrudeabove the finished floor grade.16
