Vac-Tron Equipment has developed a new gamechanger in the Micro Trenching process

Micro Trenching is one of the installation methods being utilized by contractors to bring fiber networks to consumers. Micro Trenching is an installation method in which a narrow and relatively shallow trench is cut, usually on an asphalt roadway. Trench dimensions can range from .75 to 2.24 inches wide and 8 to 16 inches deep. While cutting, a vacuum system connected to the cutter wheel cleanly diverts and transports debris away from the worksite. Once the conduit is laid, the trench is backfilled with a grout compound. Advantages of Micro Trenching include minimal cutting width that boosts installation production, reduce costs of backfill, shallow depth placement which helps avoid encounters with existing utilities and jobsite cleanliness thanks to the vacuum spoil that removes debris.

New Milton sewer tunnels through environmentally sensitive areas

The population growth of the Town of Milton, Ontario in recent years has been phenomenal. With the province’s Places to Grow legislation, this growth is expected to continue for many years. The Boyne Trunk Sanitary Sewer was identified in the Halton Region’s Wastewater Master Plan as being critical to convey existing and future flows to the Mid Halton Wastewater Treatment Plant in Oakville. The existing sewage pump station and force main conveying sewage from Milton was at its maximum capacity. The commissioning of a new major trunk sewer to replace the existing system and to convey future flows from the northern part of the region was of critical importance.

Finding the keys to Rebecca Trunk

In order to balance the needs of growing the Region of Halton with the protection and preservation of its natural and heritage resources, Halton initiated Sustainable Halton which developed goals that serve as a blueprint for building a sustainable and healthy community. The need to upgrade the existing wastewater network to service future intensification in Oakville’s Urban Growth Centre was identified as part of the process.

Geopolymers 101: Ease of application, resistance to corrosion and light environmental footprint among advantages compared to competing spray technologies and CIPP

Geopolymer is a term originally coined by French researcher Joseph Davidovits to describe a class of “cement” formed from aluminosilicates. While traditional Portland cement relies on the hydration of calcium silicates, geopolymers form by the condensation of aluminosilicates. Geopolymers are known to provide comparable or better performance to traditional cementitious binders but with the added advantages of significantly reduced greenhouse emissions, increased fire and chemical resistance, and reduced water utilization.

Dealing with root causes

On Eastlawn Street in the City of Windsor, Ontario, heritage homes on double lots with mature trees beautifully line the narrow street. Not so beautifully, white sewer access caps dot the lawns of more than half of the homeowners. It is a telling sign of the ongoing battle between concerned homeowners and the roots they cannot see underground.

A tale of two manhole fixes
