Excavation - Instruction
For general instructions, follow these steps:
Dig a hole 20 cm longer, 20 cm wider and 30 cm deeper than the dimensions of the pool basin, place the drainage pipes around the entire bottom and attach them to the drainage well, attention! drainage pipes must be wrapped with fleece and placed on the rubble bed, drainage pipes placed in the rubble are connected to the drainage well, which is placed in one corner of the trench (drainage pipes should be laid with a slope towards the drainage pit) a submersible pump should be placed in the drainage pit / drainage, which will automatically pump out all groundwater that will be collected in the well (insulated! the water pipe from the submersible pump must be connected to a storm pipe or sewer pipe)
spread the non-woven fabric across the bottom on the rubble
10 cm of sand-cement mixture (10: 1 or 8: 2 or 7: 3), moisten with water and compactly compact with a compactor
lay out 10cm mm XPS 200 polystyrene, polystyrene
check that everything is level
lift the pool with a crane and place it in the trench on a properly prepared surface
place concrete blocks under the second step of the pool (measured from the top of the pool) to support the steps and lift them gently
fill 30 cm of pool water
start scattering 30 cm around the pool, sand with cement, moistened with water and thoroughly compacted
again 30 cm of water into the pool and again 30 cm of backfill around the pool
start gluing the hoses, when you get to the skimmer and nozzles, insulate the hoses!
cover the skimmer, nozzles and lamps with sand only, no cement
the entire pool should be covered around
Beat carefully and pour water over the mixture under each step.
Make sure that the hoses coming out of the pool do not get submerged when re-sprinkling with sand and cement. You should lift the hose a little with a string attached to the hose, which can be hooked on one of the boards above the ground.
