The building procedure behind Biodesign pools involves 7 steps:
1st step – Shaping the excavation
During the excavation, the pool is shaped directly in the earth with various depths, including beaches and underwater seating areas. (Different to what occurs in the building of traditional pools, where the excavation is larger than the final pool, resulting in backfilling.) Once the excavation has been completed, the water circulation system is positioned.
2nd step – Placement of protective geo-textile material
Once the necessary hydraulic components for the correct operation of the filtration system have been positioned, a protective sheet of geo-textile material is spread in order to protect the EPDM waterproofing layer from possible damage caused by sharp stones or roots within the excavation.
3rd step – Placement of waterproof EPDM liner
A waterproof liner in EPDM is spread over the geo-textile material. Its high degree of elasticity makes allowance for any ground movement without undergoing damage or water loss. In this stage all the returns, drains and skimmers of the circulation system are flanged.
4th step – Placement of the structural net for the foundation
The first structural net for the consolidation of the rough layer is placed over the EPDM liner.
5th step – Spreading of the rough layer of structural paving
Natural granulated quartz is mixed with non-toxic resins and then spread by hand over the entire area of the pool surface.
6th step – Placement of the intermediate structural net
Once the first layer of granulated stone has dried, a second structural net is laid for the consolidation of the final layer.
7th step – Spreading of the final layer of structural paving
The granulated stone is mixed chosen by the client for the finish with non-toxic resins and spread in a second layer by hand over the entire surface of the pool. After lightly sanding the surface, a final layer of non-toxic resin is applied.
