Self-Propelled Canal Liner
G&Z offers a complete range of self-propelled, canal liners capable of lining anything from watercourses to small main canals. These liners are built using the same proven tractors found in G&Z’s popular and highly maneuverable, 4 track, highway and airport slipform pavers, featuring telescopic tractor frames with bolsters, swing legs and automatic steering and grade control that can operate in reference to a single stringline, a stringless system, or by tracing the fine-graded canal subgrade.
The maximum top width of your present or future canal typically determines which G&Z paver model is best suited. A key advantage of this system is flexibility: once your canal project is completed, the canal liner can be converted into a highway or airport slipform paver with minimal additional investment.

Efficient Concrete Placement
​
Mounted beneath the G&Z paver tractor is a full-section or half-section canal mold with a liquification hopper. The hopper is divided into compartments by baffles, each equipped with a poker vibrator for uniform concrete consolidation and finishing. A concrete distribution auger is positioned on each slope in the liquification hopper to ensure consistent coverage across canal slopes and the bottom.

For small canals with wider top widths, a concrete shuttle conveyor can be mounted off the front of the tractor to ensure concrete delivery to slope opposite the concrete feed side. As an option, charging conveyors can be provided on both sides of the canal. The charging conveyor is fed by either transit / truck mixers or a material placer when end-dump trucks are used. An access walkway — with the option to add a transverse joint cutter (“Guillotine”) — is provided at the rear of the canal mold to provide access for finishing.
-
The canal mold and attachments are sectionalized in increments of a foot or meter to accommodate different canal cross-sections. If needed, the paver tractor frame can be modified to pave in a half-span configuration for larger canals.
Mobility and Maneuverability
To navigate around obstructions in the canal alignment, the relatively lightweight canal mold can be quickly detached from the paver tractor and moved by crane and trailer and depending on the mold size a large front end loader or excavator. The heavier paver tractor is self-propelled / self-moving, highly maneuverable using the 90 degree steering mode making it easy to reposition.
