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.

1-17. (canceled)
A modular formwork system comprising modular interconnectable face panels maintained in opposed spaced relationship by modular transverse connectors, at least one course of said face panels comprising connector panels, each connector panel having a male end and a female end;
- said female end having opposed faces defining a space between them and successive rows of rearwardly inclined opposed teeth depending from said opposed faces;
- said male end being engageable into said female end of a same connector panel by inserting said male end for engagement between and against said opposed teeth, said male end being selectively engageable at varying depths between successive ones of said rows of teeth.
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, said modular panel having a plurality of apertures substantially throughout said surface for receiving stucco through said apertures, and wherein said modular panel comprises a male end and a female end;
- said male end comprising a stem terminating in a wedge-shaped tip, and a face extending in spaced relationship with said stem on the inside of said modular panel and extending past said tip;
- said female end having opposed faces defining a space between them and successive rows of rearwardly inclined opposed teeth depending from said opposed faces;
- said male end being engageable into said female end of a same modular panel by inserting said tip for engagement between and against said opposed teeth, said tip being selectively engageable at varying depths between successive ones of said rows of teeth.
