Open the CIPO recordAbstract From the Canadian patent
A modular brickwork form for producing a regular pattern in brickwork construction. Raised ledges have concave and convex dimples to interconnect with adjoining forms avoiding added space and deformation experienced by present day forms. The modular brickwork form has raised dividers and the ledges to form a continuous pattern. The lack of overlapping U-shaped edges also avoids added space between bricks and an irregular pattern of bricks. The raised ledges are also tapered to allow nesting of the forms when stacked. The forms may include ports for drainage and corrugation for added strength.
