GEOTECHNICAL: Relating to the practical application and science to the behavior of earth materials to solve problems. Geotechnical engineering, a branch of civil engineering, utilizes the principles of soil and rock mechanics to design solutions related to erosion, subsidence and other geological phenomena.
GEOTECHNICAL SPF: Spray and injected polyurethane foam systems designed for use in direct contact with soil or rock. Typical uses include soil stabilization, soil modification, concrete lifting, void filling, and infrastructure asset repairs. Geotechnical SPFs may be HYDROPHILIC or HYDROPHOBIC depending on site specific requirements.GLASS EYES, GLASS WINDOWS: A thin, clear membrane that forms over elongated polyurethane foam cells. Glass eyes may break when coated, forming a PINHOLE. (See also PINHOLE.)
GLOSS: The shine, sheen, or luster of a dried film.
GRANULE: Size No. 11 ceramic aggregate embedded into wet coating over polyurethane foam for aesthetics, traction, and mechanical resistance.GRAVEL STOP: The roof edge treatment designed to retain gravel.
