Manhole Lining & Repair

manholelining01Altair Environmental Group is an approved installer of Cementious Manhole Lining System, products used for the relining and repair of wastewater collection system manholes, wet wells or lift stations.

This is a calcium aluminate mortar pre-mix product designed specifically for the municipal wastewater industry and provides a structural, abrasion and corrosion resistant, protective lining against biogenic corrosion resulting from hydrogen sulfide (H2S) commonly found in wastewater environments.

Altair operates purpose built application systems for the installation of lining products. These systems comprise hydraulic mixer/pump units and applicators for spray application in wastewater collection systems.

Manhole, wet well and lift station rehabilitation services include the cleaning, surface preparation and inflow elimination prior to the lining application.

A range of lining products are available, some which are unique from other manhole lining materials due to its capacity to inhibit bacterial activity by effectively neutralizing sulfuric acid production in wastewater environments. These unique properties result from the chemical and mineral phases formed during the hydration process.
