With an eye on educating new technicians and reinforcing training in more experienced grouting crews from Quebec and Ontario, Aries Industries Inc., Logiball and Prime Resins joined together to host a Municipal Grout School.

Trenchless Technology
Sewer grouting is new again. The proven trenchless technology has been a staple in the sewer industry since the early 1960s and while a lot of the processes have remained the same, the concepts and techniques have changed dramatically over the last 10 years.

River Valley Highlands (RVH) in Lancaster, Ohio, is a 10-year-old subdivision with a developer-constructed sewer system. Prior to development, surface runoff followed the natural topography, running into a bowl in the middle of the development followed by a swale to the west.

City officials in Norwich, Connecticut, discovered an unusual problem involving 2,695 ft of 14-in. force main pipe in September 2019. The gritty materials, pumped on a regular basis, had worn away the bottom of the 45-year-old cast iron pipe.

As the pipeline rehabilitation market has grown, more and more technologies have reached the market and jostled for primacy as the rehab solution of choice.

Canadian Underground Infrastructure
Groundwater infiltration of sewer pipes is a common problem encountered by municipalities, especially those with aging infrastructure.

When it comes to sewer pipe rehabilitation, cured-in-place pipe (CIPP) lining and pipe bursting get most of the headlines.

The scaling of lateral connections with chemical grout is a proven technique to permanently climate infiltration from a collection system.

Trenchless Technology
Chemical grouting used in municipal sewers through remotely operated packers is typically performed from within structurally sound pipes with opened joints, leaking gaskets, annular spaces between liners and host pipes and circumferential cracks
