GigaCrete refers to a family of cementitious building products that consist of a proprietary non-silica mineral-based binder and filler materials that may include coal ash, non-silica-based sands, agricultural waste, and/or post-industrial recycled materials.[1][2] The filler varies with application and availability.[2] GigaCrete products do not contain silica-based sands [3] or Portland cement, the binder used in traditional concrete. [1][4]


GigaCrete was conceived in the early 21st century by British-born architect and industrial designer Andrew C. Dennis whose impetus was to create cementitious green building materials that are strong and lightweight.[4][5] Mr. Dennis is founder and chairman of the company.

Green building material[edit]

GigaCrete PlasterMax, a LEED qualified interior wall coating,[6] was listed as a green building material by Architectural Record [7][8][9] and selected by BUILDERNews magazine [10] as a Best Products 2007 Winner.[11][12]

The Greenguard Environmental Institute (GEI) certified GigaCrete PlasterMax as a Low-Emitting Listed Product.[13] "The GREENGUARD Environmental Institute is an industry-independent, non-profit organization that oversees the GREENGUARD Certification ProgramSM. As an ANSI Authorized Standards Developer, GEI establishes acceptable indoor air standards for indoor products, environments, and buildings." [14]

In 2007, Popular Mechanics magazine awarded a Best in Green Design to panels made with GigaCrete hydraulic cement and waste materials.[2]

On February 14, 2008, the U.S. Department of Energy (DOE) challenged the homebuilding trade to construct 220,000 "high-performance" homes by 2012 that score 70 or lower on the EnergySmart Home Scale.[15] To qualify as high-performance, a home must use 30%-or-less energy than a typical new home built per the 2006 International Energy Conservation Code.[15] In early 2009, Next Gen 09 LLC, in partnership with the DOE Builders Challenge program, built a high-performance 5,200-square-foot (480 m2) demonstration home outside Las Vegas, Nevada.[16] The Pittsburgh Post-Gazette reported that GigaCrete PlasterMax was used as the interior-wall finish of that high-performance Las Vegas home.[17]

Plastermax on ICF[edit]

GigaCrete Plastermax is a fire-resistance rated[18] interior wall coating for insulating concrete forms (ICF), thereby providing a green alternative to gypsum drywall on ICF. When sprayed or troweled onto the polystyrene foam facade of stacked ICF blocks, Plastermax forms an abuse-resistant surface.[19][20]
