Pouring the concrete slab

5.4.1 Rebar

Before pouring the concrete, lay the top layer of welded rebar mesh (type ST25C) over the floor of the
excavation (the mesh should be set back 3 to 5 cm from the edge around the entire periphery). Some
cutting around the supporting braces will be necessary.
The mesh should overlap by one and a half squares and should be connected together using metal ties.
The mesh should be raised using spacers to ensure that will sit in the centre of the slab. If you are using
self-levelling concrete, you should place a layer of polyethylene sheeting under the rebar mesh because
the concrete is very liquid and could flow into the spaces between the gravel. Use C25/30 grade concrete
as a minimum.

5.4.2 Slab dimensions

The characteristics of the concrete slab are provided in
The dimensions of the slab are such the feet of the wooden pool access ladder will not rest on the slab.
However, we recommend that the feet of the ladder rest on a solid surface (cement blocks or slab for
example).
While pouring the slab over the floor of the excavation, make sure that the upper rebar mesh is properly
encased in the concrete: the layer of concrete above the mesh must be at least 3 cm thick.
Refer to Figure 5 to determine the depth of the slab to be poured: it should be 150 mm thick, and of a
height to ensure that the distance between the surface of the slab and the top of the excavation is 1303
mm if the pool is to be installed in-ground.
Level and smooth the slab carefully to void surface defects that will have to be corrected later.
The slab provides seating for the wooden structure. Any levelling defects will become apparent when
the pool is filled with water. Similarly, significant surface defects will detract from the quality of the
finish of the pool floor.
