CertainTeed’s CertaForm flexible flatwork form

CertainTeed’s new CertaForm flexible flatwork form allows contractors to more easily tackle curved designs for projects such as patios, driveways, and decks. CertaForm is made of cellular polyvinyl chloride (PVC) that does not absorb moisture, is chemical resistant, cleans quickly, and does not warp or crack. It can be reused multiple times, is easy to transport, and can be easily drilled, nailed, and staked.
