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.
3) Place and level patio blocks into trenches. Make sure that the
top of the slab is 8cm (3 1/4”) deep. Top of framework must be
level with pool area.
