Use vacuum excavation for safe digging
April is National Safe Digging month and every year many companies, including 811 and Click Before You Dig, promote the importance of having a plan before you begin digging. Every six minutes an underground utility line is damaged and the growing trend in preventing these accidents is utilizing vacuum excavation. There are many instances when vacuum excavation is the safest and most productive option for digging compared to traditional excavation.
Digging around lines using vacuum excavation is less intrusive to the surrounding dig site and provides a cleaner hole. It exposes the piping without abrasive force compared to a front-end loader or shovel. Air or hydro vacuum excavation dramatically reduces the chance of a cut or break into the utility lines which helps with cost, safety, and time.
Directional-bore projects, specifically those areas where the bore route will cross other utilities, and especially when the bore route crosses natural gas lines buried within the road or other paved areas, is another example of when vacuum excavation is the best option. A gas line strike with traditional excavation is one of the worst disasters a project can incur and happens too often. Vacuum excavation is a much safer alternative when digging around gas lines.
The cost of damaging utilities can range from environmental contamination, project delays, lost time and productivity and even more tragically, death.
Because vacuum excavation is so safe and precise, it is even being used for trench rescues due to the speed and safety of removing the soil from around a victim.
Be sure to use proper protective gear while using a vacuum excavator. This usually includes rubber steel-toe boots, safety glasses, face shield, hard hat, gloves, safety vest and hearing protection.
Vacuum excavation is used worldwide and has quickly grown into the best method for safer digging.

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.

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.
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.
