The Perma-Liner trenchless CIPMH (cured-in-place manhole liner) one-size liner provides all the benefits of CIPP. It is simple to install and completely renews a manhole in a couple of hours. It requires no digging, resulting in minimal disruption to the public. It is made to fit all manholes, including barrel sections, eccentric and concentric cones constructed of brick and mortar, precast or block. The liner for chimney or full-depth manholes eliminates infiltration and inflow through manhole walls. This universal-sized liner is engineered to resist freeze-thaw cycles and create a watertight, corrosion-resistant structural lining. 866/336-2568; www.perma-liner.com.
