The H-Forms system requires a fraction of resources used on conventional Concrete Masonry Unit (CMU) landscape wall construction, and virtually eliminates waste.
H-Forms are manufactured with expanded polystyrene (EPS), a closed-cell, lightweight rigid-foam made from by-products of the refining of crude oil. EPS does not contain chlorofluorocarbons (CFCs) or formaldehyde. Easily recycled, EPS is a commodity of high value for producers of recycled plastic. They are manufactured under strict EPA guidelines and tested periodically by UL.
H-Forms blocks have one-third to one-quarter of the embodied energy (the energy required to mine, harvest, grow, manufacture, ship and unload material to a building site) of concrete masonry units (CMUs).
