System and method for forming prefabricated building panels

A system according to any preceding claim, wherein the resilient spacers are cut from a strip of resilient material of indeterminate length.

A system according to any preceding claim, wherein the resilient spacers are formed from a rubber, plastic or foam resilient material that is flexible, elastic, durable and releasable from concrete.

A system according to any preceding claim, wherein the at least one planar member has a surface coating that is releasable from, or resists bonding to, concrete.

A system according to any preceding claim, wherein the at least one planar member comprises expanded plastic sheet material.

A kit of parts, comprising:

• at least one planar member having a two- or three-dimensional surface pattern formed thereon or therein;
• and
• a plurality of resilient spacers removably positionable on or in the surface pattern to form a surface relief pattern of spaced-apart recesses on the at least one planar member.

A method, comprising:

• forming a surface pattern on or in at least one planar member;
• and
• providing a plurality of resilient spacers that are removably positionable on or in the surface pattern to form a surface relief pattern of spaced-apart recesses on the at least one planar member.
