Manhole SolutionsManhole Rehabilitation and Repair

As long as there have been manholes, there has been a need to repair them.  But, until recently, there have been more problems than solutions.  Now, IPR offers solutions that range from stopping cover leaks to complete manhole rehabilitation.  And we have the expertise to know which product to use in each situation.

Manholes should be protected both inside and out. Chemical grouts are the best protection for the outside.  The inside should be cleaned and lined with a product which will protect it from corrosion and provide structural integrity.  IPR solutions to stop leaks include the following:

  • Fast-set cementitious products that harden in about 1 minute to stop small to medium size active leaks.

  •  A tough, low viscosity, calcium aluminate that stops medium to high volume leaks and has controlled reaction times of 30 seconds to 3 minutes.

  • Grouts, which are a versatile, high viscosity, hydrophobic polyurethane that cures to into a flexible-foam like a hydrophilic. Can be used with or without accelerator to achieve reaction times from 20 seconds to 1 ½ minutes.

 In many cases, a manhole damaged by hydrogen sulfide can be rehabilitated with our calcium aluminate based, fiber-reinforced liner. It can be applied up to 2” thick in one coat. When a calcium aluminate product is just not enough by itself, use our 100% solids epoxy as a topcoat for added corrosion protection. Thicknesses up to 80 mils per coat and designed to provide a minimum service life of 50 years. Holes can be drilled and the grout can be applied internally or external application is easy using a brush, roller or single pot airless spray equipment.
