1. A method of forming architectural concrete walls, comprising the steps of:
- selecting a plurality of modular form panel units, each comprising a generally rectangular support frame of multiple parallel base beams normally disposed horizontally, a plurality of closely spaced pairs of backing beams normally disposed vertically and secured to a back of said base beams, a plurality of backing sheets secured to a front of said base beams, a plurality of facing sheets overlying and secured to said backing sheets, each facing sheet having a smooth facing surface defined by a plastic material, and an elastic seal member mounted along a side edge of each modular form unit, the seal member being supported on the backing sheet and disposed at the edge of the facing sheet for sealing between adjacent modular form units for preventing water leakage;
arranging a plurality of said form panel units in opposed facing relationship for forming a predetermined section of wall;
positioning said elastic seal means between adjacent modular form panel units for preventing water leakage;
installing a tie rod assembly in aligned tie holes of opposed form panel units;
installing a seal tube assembly for sealing each tie rod assembly;
tieing said opposed form panel units together by means of said tie rod assembly;
filling the space between the form panel units with a quantity of concrete mix;
allowing said concrete mix to cure and;
removing the form panel units.

Abstract
A system for forming architectural concrete walls, comprises a plurality of modular form units, each form unit comprising a generally rectangular support frame, a backing sheet and an overlying facing sheet, each facing sheet having a facing surface defined by a plastic material, an elastic seal along an edge of the form unit for positioning between adjacent form units for preventing water leakage, a minimal number of tie holes extending through the each form unit, a seal tube assembly for positioning between the tie holes, and a tie rod for each tie hole.

13. A method of forming architectural concrete walls having a highly polished surface appearance, comprising the steps of:
-
selecting a plurality of modular form units, each comprising a generally rectangular support frame of multiple beams, a plurality of backing sheets secured to a front of said beams, a plurality of facing sheets overlying and secured to said backing sheets, each facing sheet having a facing surface defined by a smooth plastic material, and an elastic seal member mounted along a side edge of said modular form unit, disposed along edges of the facing sheet for sealing between adjacent modular form units for preventing water leakage; arranging a plurality of said form panel units in opposed facing relationship for forming a predetermined section of wall; installing a tie rod assembly in aligned tie holes of opposed form panel units; installing a seal tube assembly for sealing each tie rod assembly; tieing said opposed form panel units together by means of said tie rod tie assemblies; filling the space between the form panel units with a quantity of concrete mix which includes a quantity of gray diatomaceous earth; inserting a vibrator inside the form during pouring of the concrete; operating said vibrator a sufficient length of time to eliminate surface air pockets and thereby provide a smooth surface having a polished marble-like appearance; allowing said concrete mix to cure, and removing said modular form units. - View Dependent Claims (14)

15. A method of forming architectural concrete wall panels having a highly polished surface appearance, comprising the steps of:
-
selecting and arranging plurality of modular form units into an three dimensional array forming a three dimensional cavity for molding concrete into a wall panel having a finished surface, said step of selecting includes selecting at least one of said panels comprising a generally rectangular support frame of multiple beams, a facing sheet formed of a laminate of plywood having a facing surface defined by a smooth plastic material of about one-tenth inch thick, said facing sheet mounted on and secured to said support frame, and an elastic seal member mounted along edges of the facing sheet for sealing between adjacent modular form units for preventing water leakage; forming a mixture of pourable concrete having a quantity of diatomacous earth in sufficient quantity to impart a marble like color to a surface formed by said concrete; pouring a quantity of said concrete into said cavity formed by said array of form panel units; inserting a vibrator into said cavity after pouring at least some of the concrete; operating said vibrator a sufficient length of time to eliminate surface air pockets and thereby provide a smooth surface having a polished marble-like appearance; allowing said concrete mix to cure; and removing said form units. - View Dependent Claims (16, 17)
