ABSTRACT:
The customary method to prepare the pool bottoms in order to install the vinyl liners is with even, smooth surfaces. Difficulties occur when draining a vinyl liner pool in order to change the water, repair the liner, clean the grease from the liner, or remove the impurities from the pool bottom.
In the method which I propose, the pool bottom is finished with plastic or rubber tiles which are pitched in the ground. The upper surface of the tiles is deeply impressed with geometrical designs and cramped channels which allow flow of the underliner air towards a permanent vacuum system at any time. Thus, whenever it is necessary, the liner is sucked to the pool bottom by higher pressures than the normal water pressure of the pool, and the liner maintains its shape firmly until the pool is able to be refilled.
