McLaughlin launched its biggest machine to date at the CONEXPO-CON/AGG 2017 trade show. The McL-60 Workhorse is a 60-inch (152.4-cm) auger boring machine designed with operator convenience in mind. The low-profile engine design, remote control operation and Rabbit Travel help water, sewer and pipeline contractors install large-diameter casings at a lower cost than directional drilling
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.
Advanced Drainage Systems, Inc. (ADS) (NYSE: WMS), a leading global manufacturer of water management solutions, today announced its latest breakthrough in storm water pipe technology, HPXTM 75. This new technology provides heightened levels of stiffness, is available in a range of sizes, and yields significant cost benefits for customers compared to alternative products.
TT Technologies recently introduced a new cutterhead configuration for its Grundoburst static pipe bursting system. The new configuration consists of three specially designed bladed, roller cutterheads in succession. The bladed roller cutting head configuration allows contractors to burst/split large diameter steel and ductile iron pipes when used with larger Grundoburst static bursting systems. The new special cutterhead design allows for a smoother host pipe cut and greater protection for the new pipe.
Vac-Tron Equipment is on a roll. Only one year after releasing their very first HTV (Hydro Truck Vac) PTO, they are now introducing their NEW JTV (Jetter Truck Vac) PTO series. The JTV 873 PTO is a new series of PTO truck driven systems that combine vacuum excavation with high pressure jetter capabilities putting this truck in a league of its own.
Avanti International’s AV-248-LV Flexseal LV, AV-275 Soilgrout and AV-315 Microfoam are now certified by the Water Quality Association (WQA) as tested and certified against NSF/ANSI Standard 61 - Drinking Water System Components. Avanti’s products are used to stop leaks, stabilize soil, and control groundwater in municipal, industrial, and geotechnical applications. According to technical director Roger Borremans, “These three products join three other Avanti resins earning Potable Water Certification. Engineers now have more choices between hydrophilic and hydrophobic resins for specifying the exact right product in potable water applications.”
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.
When an old storm water sewer that crossed below a highway and a highly frequented shopping avenue in the City of Quebec partly collapsed and had to be replaced, the city government was presented with a challenge. The solution required a method to renovate the pipeline while keeping traffic disruptions to a minimum.
McLaughlin has introduced the new ECO truck-mounted vacuum excavator series to answer the market’s demand for a compact vacuum excavation system that focuses on performance and improved fuel efficiency. Powered by 49, 85 or 99 horsepower (37, 63 or 74 kW) auxiliary engines, ECO Series vacuum excavators offer utility contractors fuel economy, lower operating costs and reduced maintenance. With the ability to choose from 500- to 1200-gallon (1892.7 to 3028.3 L) spoil tank capacities ― and the ability to mount ECO Series units on both new and used truck chassis ― contractors can customize the truck vacuum excavator to their specific needs.
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.
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.
Canadian contractors are cost effectively rehabilitating failing manholes and sewers without excavation or barrel replacement using the Permacast and CentriPipe systems developed by AP/M Permaform (AP/M) and distributed by Martech, Inc. Edmonton-based OSCO Mudjacking & Shotcreting Ltd. applied Permacast on two manhole projects with widely varying challenges:
- A new 9-metre manhole installed as part of Edmonton’s massive project converting the QE II Highway and 41 Avenue SW connection to a grade-separated interchange.
- Six failing manholes in remote Carmacks, a Yukon village.
