For the majority of projects, Ungar provides all material, labour, equipment and services necessary for the construction of the project. When needed, Ungar coordinates specialized subcontractors to perform portions of the work required. Project managers are assigned to ensure that communication between the contractor, engineer and customer is always kept.

Water and Sewer Installation/ Municipal Infrastructure - Residential and commercial servicing to 1500mm trunk main. Ungar has extensive experience with high density polyethylene, PVC, cast iron, stainless steel and concrete pipe of all sizes. Ungar provides solutions for dewatering, sewer bypassing and temporary water.

Ungar Construction has provided water, sewer and storm sewer infrastructure services for municipalities, corporations and private developments for over 35 years. Generally these projects require a variety of pipework materials, geosynthetics, and granular materials. We always have trained, professional, and qualified installers oversee the installation and construction of all components of the project, but primary pipelayers are tasked to install the following pipework materials:

  • HDPE
  • PVC
  • Concrete
  • Steel
  • Stainless steel
  • CSP

Most projects require tie into existing infrastructure, with necessary upgrades, some are greenfield sites. Our qualified installers can assess and recommend necessary upgrades if needed to ensure the best value for the owner. Techniques include trenching, directional drilling and pipe bursting. We work with qualified professionals when conventional trenching methods are not an option for the project.

Ungar employs Journeyman and Apprentice crane operators. Ungar owns an American 60T Crawler crane and Peterbuilt 30T mobile crane.

20+ years of experience in derailment cleanup for Canadian Pacific Railway, Canadian National Rail, Mosaic mines, Bunge, Louis Dreyfus and Broadgrain. Railroad Emergency 24-Hour Line- 306-621-8286 or 306-621-3989

Process, supply and delivery of: Ballast, Sub-Ballast, Type 8 Subbase, Type 33 Base Course, 1” Minus crushed rock, Rip-rap and Sand.

Some of these projects have been our favourites. We have constructed primary and storage lagoon cells, as well as landfill cells where groundwater was problematic resulting in significant inflow into excavations. We will accommodate the owners schedule and if needed, facilitate winter construction. Many sites require erosion control blankets, geotextiles and synthetics liners, as well as tying into existing infrastructure from neighboring communities, or if a landfill, construction of a leachate collection system is necessary. Ungar Construction can source and secure all the materials for the project including granular material. Collaboration with the engineers and owners is always a priority and often we compare and share survey data to enable our GPS automated equipment to streamline the construction process.
