3. MAKE THE AREA MARKED OUT FLAT, LEVEL AND
COMPACTED
Remember: Your pool must be perfectly level. Any deviation in the level plane must not
exceed 25 mm (Fig. 2B-6).
a. Replace the pin with the flat-topped stake with a cross-section of at least 25x25
mm and a length of at least 15 cm. Drive it down flush with the ground surface.
b. Use a 5x10 cm block whose length corresponds to the size of the pool (see the
above table). Drive a sufficiently long nail into one end. Use the nail to keep the
end of the block on the stake when you are rotating the block in the circle (Fig.
2B-4).
c. Drill a hole in the centre of the stake, sufficiently large and deep so that the nail
can rotate in it. It must be possible to pull out the nail easily from the stake and
enable it to rotate freely around its own axis.
d. Now insert the block with the nail into the stake hole. Put the spirit level onto the
block and shift the block into the circle around the end driven into the stake and
identify the high spots and low areas this way (Fig. 2B-5).
e. Remove all the high spots with a shovel, hoe or rake. Remember, your pool must be
level within a tolerance of 25 mm across the pool (Fig. 2B-6).
f. Do not fill in low areas (Fig. 2B-7). Filling will create an unsafe foundation for your
pool. Holes from small stones and small dips and hollows may be filled in, but the
soil must be hard-packed with a tamping tool.
g. In order to ensure the future stability of the pool it is now necessary to compact
the base by using a tamping tool. If the base is not compacted, it can settle down
under the pressure of the filled pool and thus cause the pool to collapse. Fill in and
compact the low areas.
Hint:
Walk on the surface. No traces should be visible on a properly
compacted surface.
Remember:
The outer 30 cm of the cleared oval area must be perfectly flat (Image
2B-8). The bottom edge of the pool must rest flat on the ground and have no gaps
under it. Ensure this area is perfectly flat, level and compacted.
Hint:
We would recommend that a felt pad is laid on the compacted sand
base prior to assembling the bottom rails.
