<p>A system for forming architectural concrete walls comprises a plurality of modular form units (32), each form unit comprising a generally rectangular support frame, a backing sheet (34, 36) and an overlying facing sheet (56; 58), each facing sheet having a facing surface defined by a plastic material, an elastic seal (68) along an edge of the form unit for positioning between adjacent form units for preventing water leakage, a minimal number of tie holes (26) extending through each form unit, a seal tube (74) assembly for positioning between the tie holes, and a tie rod (80) for each tie hole. An architectural concrete wall having minimal tie holes and surface cavities and a highly polished marble-like surface is formed of a concrete mix including diatomaceous earth to impart a grey marble color and appearance.</p> |
