PART 2B
PREPARING THE BASE FOR A ROUND POOL
Important:
The area under the pool must comply with the following conditions:
1) It must be level,
This means to a tolerance of maximum of 2.5 cm.
2) It must be covered with a thin layer of sieved sand,
This means that sand will level any small flatness differences in the area arising
after the use of work tools (pick, hoe, etc.). The layer should not exceed 2cm and
must cover the entire area of the pool.
3) It must be compacted,
It should be sufficiently firm that a person weighing at least 80 kg leaves no
visible traces on the surface.
1. MARK OUT THE AREA
a. Drive a pin into the ground at the point which should be the centre of the pool
(Fig. 2B-1).
b. Use a length of string tied between the pin and a can of sand or lime, flour,
etc., and mark a circle on the ground. The radius of the circle will be at least 15
cm bigger than that of the pool. (Image 2B-2). The length of the string for the
corresponding pool size is shown in the table.
