Abstract
A stay-in-place concrete formwork system allows stucco to be applied directly to the formwork, avoiding the need to provide a further surface treatment of the wall prior to applying stucco. Apertures are provided on an exterior facing wall of the formwork panel to receive and embed stucco therein. The panel may also be formed with outward stucco-engaging projections. Other features include using rigid insulation to brace the stucco and keep concrete from the apertures, a sealing joint element, extendible panels for use in curved formwork, rainscreen features and an alligator connector panel for adjustable lengths of formwork faces.
Claims9
A method of using a modular panel adapted to be interconnected to other formwork panels to form stay-in-place concrete formwork to form an outward-facing wall panel of said formwork and having an outward facing substantially planar surface, wherein said modular panel has a plurality of apertures substantially throughout said surface for receiving stucco through said apertures and a plurality of projections extending inwardly from said planar surface, comprising:
- assembling said stay-in-place concrete formwork;
- installing rigid insulation against said projections such that a gap is formed between said rigid insulation and said modular panel;
- pouring concrete into said formwork;
- and
- applying stucco to an outside side of said planar surface so that said stucco embeds into said apertures and said gap.
