Manhole Rehabilitation

Manhole grouting is a viable rehabilitation technique utilized to prevent runoff and groundwater from seeping into manhole. Grouts have a variety of chemical formulas that are matched to be compatible with local soil conditions and manhole materials to prevent the growth of fungus and resistant to erosion of waste water; thus enhancing the lifespan of manhole.
