ABSTRACT:
A concrete in-ground swimming pool is given a resin bonded glass fiber liner that is securely bonded to the upper rim of the concrete pool wall 10 just below the coping 11. This is done with two saw cuts 15 and 16 inclined to each other to diverge with increasing depth of about 3/4" into the concrete wall below the coping so that material between the saw cuts can be cleaned out to form a dovetail shaped recess 17. A mixture of polyester resin and glass fibers fills the dovetail recess and covers over the upper pool wall and a narrow band around the upper rim of the pool in the region of the dovetail to form a bonding surface 21 locked to the recess. This is sanded smooth after the resin sets, and then the pool is lined with glass fiber mats 25 coated with polyester resin 26 that bonds to the bonding surface to form a waterproof liner bonded to the upper rim of the pool and supported by the concrete that serves as a mold.
