Abstract
A method of forming walls for pools, waterfalls and the like having surfaces accurately simulating material surfaces, such as rock surfaces. The method is comprised of the steps of coating a rock surface to be simulated with latex, coating the latex with urethane resin, and allowing the resin to foam in place. The urethane foam-latex member is then removed from the rock to be simulated and is used as one wall of the pouring form for forming the corresponding wall of the pool, etc. In the case of swimming pools, a trench in the position of the desired walls of a pool can be dug with the inner surfaces of the trench provided with the foam-latex panels for forming the simulated rock surface on the resulting pool walls. Alternate embodiments and methods of practicing the invention are disclosed.
Claims6
A method of simulating a natural rock surface comprising the steps of:
- a. applying a material on the surface of said natural rock to form a mother mold having a surface form conforming to said surface of said natural rock;
- b. applying polyurethane to said mother mold such that said polyurethane foams in place to form a mold panel, said polyurethane supporting said mother mold against hydrostatic pressures such that said surface form of said mother mold conforming to said natural rock surface does not distort, said mold panel being constructed of a closed cell semi rigid foam so as to avoid unnecessary water absorption and to provide sufficient support against typical hydrostatic pressures to which the mold may be subjected.
- c. removing said mold panel from said natural rock surface;
- d. supporting said mold panel with the exposed face of said mold in the desired location of the simulated surface;
- e. providing a cementitious material against said exposed face of said mother mold;
- and
- f. removing said mold panel after the cementitious material has cured;
- whereby a natural rock may be simulated including many of the natural details.
A method of forming pool walls simulating rock surfaces and the like comprising the steps of:
- a. digging a trench in the outline of the pool walls to be formed;
- b. providing mold panels formed by the steps of:
- 1. applying liquid latex on the surface to form a rubber film having a surface form conforming to the surface to be simulated;
- 2. applying polyurethane resin to the rubber film and allowing the resin to foam in place to form a rubber film-urethane foam mold panel, said support material supporting said mother mold against hydrostatic pressures such that said surface form of said mother mold conforming to said surface to be simulated does not distort;
- 3. removing the mold panel from the surface to be simulated.
- c. disposing the mold panels in the trench adjacent the inner wall thereof with the latex surface facing outward;
- d. providing a steel reinforcing network in the trench;
- e. positioning the bottom of said network such that bars penetrate the earth adjacent the bottom of said trench at points spaced above said bottom of said trench to form reinforcing tie points for a pool bottom;
- f. filling the remainder of the trench adjacent the mold panels with a cementitious material to form the pool walls;
- g. removing the earth within the pool walls after the cementitious material has cured;
- h. removing the mold panels and;
- i. forming said pool bottom which connects with said reinforcing tie points.
