Water SystemsReference — Not a Buildable Spec

GCCM (Concrete Fabric / Concrete Canvas) Pond Lining

A dry-cement fabric mat that cures rock-hard in ~24hrs — a faster, walkable alternative to poured ferrocement or EPDM liner.

Status

Product mechanism is manufacturer-documented/verifiable (ASTM D8364 GCCM standard). Application notes here are Claude-assisted synthesis, not yet field-tested by Zach. Needs further investigation: verify specific product/brand, seam overlap spec, source video.
