Abstract
A polymeric structural support membrane composed of a polymer that is an initiator induced reaction product of a monomer, a co-monomer, an initiator, and optionally a crosslinking agent and a fire retardant, is applied to the surfaces of an excavation to provide structural support. The polymer is a reaction product of a monofunctional monomer and co-monomer. The membrane formed has a tensile strength and a thickness sufficient to provide support to the exposed surfaces in the excavation and can be applied by spraying, brushing, pumping or rolling.
