The CIPMH manhole system from LMK Technologies is engineered to produce a cured-in-place seal that resists freeze/thaw conditions. Since it uses a stretchable liner, site preparation and installation can occur in the same day, eliminating the lead time for ordering. It can be installed as a chimney seal or as a full-depth manhole lining. Once the liner has been vacuum-impregnated and manually inverted into the manhole, the liner will cure ambiently under pressure in one to two hours depending on depth. The end result structurally renews the repaired area while simultaneously reducing I&I. 815/433-1275; www.lmktechnologies.com.
