SITE LEVELLING

For an oval pool, the bottom must absolutely be levelled, using a
carpenter's level and a straight plank. Eliminate any protrusions.
Ensure that the surface is free of debris such as rocks, wood, etc.

TRENCHES FOR BUTTRESS ASSEMBLIES

1) Dig trenches to a depth equal to the thickness of the patio blocks
(2" thick slabs recommended) and the thickness of the buttress
assembly beam 8cm (3 1/4").
(Refer to illustrations for trench layout details).
2) Make sure trenches are smooth and leveled without compacting
them.
