ABSTRACT
Microbiologically enhanced crack remediation (MECR) utilizes a biological byproduct, CaCO3 which has shown a wide range of application potential as a sealant (Ramachandran et al, 2001). Its prospective applications include remediation of surface cracks and fissures in various structural formations, in-base and sub-base stabilization, and surface soil consolidation. In principle, MECR continues as microbial metabolic activities go on. This inorganic sealant not only is environmentally innocuous but also persists in environments for a prolonged period, (Bang et al, 2001).
