ANGULAR PALLET
PT 1½ “ x 3/16
Fig. 15
These steps should be followed when filling in the joints :
a. Use the angular pallet to remove any strange elements from the
joints. The size of the pallet will depend on the thickness of the
joint.
b. Use the angular pallet to compact the natural soil of the joint. The
pallet is useful for two purposes: cleaning and compacting.
c. Prime the inner surface of the joint with a tar and kerosene
solution in a proportion of 1 to 3, so that it has the viscosity of
malleable paint. It should be applied with a paint brush.
d. Place a mixture of hot tar and fine sand in a proportion of 1 tin of
tar to 4 tins of sand. Begin by heating the tar, then add the sand
gradually, stirring constantly until it has the consistency of black
sugar.
This mixture should be applied to the banks first and then to the bottom
in layers, compacting it with the same angular pallet. Try not to extend
beyond the level of the canal lining.

the canal is built.
