Z886 PERMA-TRENCH
INSTALLATION INSTRUCTIONS
Z886 Connecting
the Trench
Channels should be installed from deep or outlet end
to shallow end. This allows the next shallower channel’s
male connection to easily set onto the previous channel
lip. Stake in place with No. 4 rebar (by others) and attach
with the provided connection hardware.
SEALING
• Channel connections are designed to be a good seal,
meaning concrete aggregate will not intrude into
the trench.
• Silicone sealant may be used as a gasket between the
channels for a better seal.
• Channel connections may be welded with an HDPE
welding gun for the best seal.
CONNECTIONS
• The maximum gap between frames is 1/4" [6].
Rebar length dictated by trench depth and substrate for positive
anchoring while setting to resist floating.
