TWO IMPORTANT PHASES TO REMEMBER:
First of all, the geotextile (bidim) is placed at the bottom of the excavation so that it conforms to the dimensions of the pool. Marks will be established to allow the correct positioning of the hull when it is wedged in place.
Then, it is necessary to fill in with crushed gravel up to the height of the defined rules. The gravel is spread over the surface of your earthwork to a thickness of between 10 and 15 centimetres. This will allow any defects in the earthwork to be rectified. It is important to remember that crushed gravel must always be used in the construction of a draining base.
