LMK’s universal, stretchable, one-size fits all CIPMH™ manhole system is engineered to produce a structural cured-in-place seal that resists freeze thaw conditions.  Since the CIPMH™ utilizes a patented, stretchable liner site preparation and installation can occur in the same day which eliminates the lead time for ordering. CIPMH™ can be installed as a structural chimney seal or full depth CIPP manhole lining. Once the liner has been vacuum impregnated and manually inverted into the manhole the liner will cure ambiently under pressure for one to two hours depending on depth.

CUES offers new software for Manhole Assessment that is easy to use, leverages GIS and GPS map data, and ensures that inspection data is checked for errors and retained in a central office database for analysis and prioritization.  Granite XP software is designed to support both custom coding standards as well as NASSCO’s MACP (Manhole Assessment and Certification Program).  Granite XP identifies each specific component of the manhole so they can be prioritized into a City’s Capital Plan.  Contact CUES for a discussion and demonstration!

PAM Covers  
There are over 6 million PAM units in the ground around the world utilizing technically advanced materials and engineering. Our focus on the needs of the end-user – rather than developing products merely to meet a minimum performance standard – led us to ductile iron, a superior alternative to cast iron in terms of weight, strength and designability. PAM manhole covers and gratings represent a quantum leap in ergonomics, safety, durability and overall product performance.


SewperCoat®, the only proven 100% calcium aluminate solution, is designed specifically for the municipal wastewater industry to provide a structural, abrasion and corrosion-resistant, protective lining against biogenic corrosion relative to hydrogen sulfide (H2S) found in wastewater environments.  With decades of worldwide performance, its unique chemistry resists the effects of biogenic corrosion for generations.

Both the cement and aggregate are 100% pure fused calcium aluminate.  This provides a level of protection that other CA based mortars with a natural aggregate system simply cannot achieve.   In addition to its proven track record, SewperCoat® is also backed by a no-nonsense 10-year labor and materials replacement warranty.
