The federal government has ordered other cities to spend millions on green drainage methods — $42 million in Cleveland alone.
This work raises the possibility of using recycled rubber from tires as a drainage layer in green roofs, substituting the porous stone materials currently used (such as expanded clay, expanded shale, pumice, and natural puzolana).
Specifically in this paper the possibility of using rubber crumbs as drainage layer in green roofs instead of the porous stone materials currently used in some commercial solutions (such as expanded clay, pumice, natural puzolana, etc) is suggested.
Pérez et al. (2012) investigated the use of rubber crumbs as drainage layer in green roof establishment.
Technical experts say the green drainage measures should generally be cheaper than running the water into the sewers, but house builders want flexibility.
Technical experts say this is a poor solution compared with surface features, adding that green drainage measures are typically cheaper than carrying water away in a pipe.
The results of their research raised the possibility of using recycled rubber from tires as a drainage layer in green roofs, substituting the porous stone materials currently used.
