New Installation

For areas where this is no pipe to rehabilitate or replace via Pipe Bursting, we turn to Pipe Jacking, Horizontal Directional Drilling (HDD) and Microtunneling for solutions. On projects that are so short as to not justify Pipe Bursting, open cut pipe installation can be used.

PW Trenchless has often worked with HDD contractors as the general contractor and provides the equipment needed to stage the pipe, prior to and during the drill, to dig the entrance and exit pits, and to complete the tie-ins to existing utilities. Sometimes they work with an HDD contractor to provide the excavating expertise and to help with staging the pipes etc.

Depending on the size of the pipe being installed via HDD, the entrance pit and exit pits can be very complex. Also, depending on the pipe size, the welding or fusing of the pipes can require much planning, manpower and equipment.

For Microtunneling, PW Trenchless completed the first Western Canadian Microtunneling project. The City of Vancouver needed a new trunk line for their Sanitary Sewer and the run up Clark Drive under Hastings Street was completed using Iseki equipment and only one technician from Iseki to control the microtunneling.

PW Trenchless has formerly completed many projects using conventional open cut techniques for pipe installation. If the project requires it, PW Trenchless has all the equipment and trained technicians needed to complete any open cut project. Many projects have a number of bursts, CIPP lining and new sections of pipe, all part of an overall contract to upgrade a City’s infrastructure.

Projects with New Installation

New Westminster 2015 Sewer Rehabilitation Program – Pipe Bursting

A prime example of the less invasive nature of trenchless construction in action. Intricate work zones accurately positioned throughout densely tree-lined streets allowed for the replacement of deteriorating sewers. Up-sized to exceed current capacity requirements, providing results long into the …

Our Services

Design - Build

An alternate tendering process where the contract is awarded to one entity which comprises both engineering and contracting.

Because PW Trenchless Construction offers such innovative solutions for underground utilities, it is often beneficial for the owner to request solutions based on a performance specification. This allows PW Trenchess to offer unique solutions while working with equally innovative engineering companies.

Pipe Replacement & Rehabilitation

In this day & age of pipe systems reaching the end of their projected lifespan, pipe replacement and pipe rehabilitation have become major fields of engineering.

PW Trenchless Construction provides viable options such as pipe bursting, loose fit lining and internal pipe re-construction whether partial & fully circumferential.

Culvert Rehabilitation

The aging culverts under roads and highways in many case have reached the end of their engineered life-span. We consider the rehabilitation or replacement of these culverts to be vital to our built environment.

PW Trenchless has been a pioneer in working with MOTH, railway companies and municipalities in developing rehabilitation methodologies for the hundreds of thousands of culverts that currently exist in BC. We have offered solutions in both procurement and construction from design-build to sliplining, invert rehabilitation and full circumferential relining.

Point Repairs

Often pipe failure can be concentrated to one section, for various reason, leaving the rest of the pipe in good condition. The repair of these localized failures are know as external point repairs (EPR's).

EPR's demonstrate PW's ability to work as both a trenchless and civil contractor, completing EPR contracts using our civil contracting skills and assisting other pure trenchless contractors who only have the capacity to work in an existing pipe.

Pipe Upsizing

Pipe upsizing is the fundamental concept of pipe bursting.

The vast majority of pipes are less than or equal to 200mm in diameter, but with today's densification practices of urban design, there is a major demand to increase current capacity to handle extra flow. Pipe bursting provides the ideal solution to this issue, particularly in an urban setting .

Horizontal Directional Drilling

Horizontal Directional Drilling is a low impact Trenchless construction service where pipe is installed in a shallow arc along a bore path which has been created by a drilling rig. Often the terms Horizontal Directional Drilling (HDD) and Directional Boring are used interchangeably, but in our industry we use the word “boring” when we utilize smaller sized drilling rigs with small diameters for short crossings in the hundreds of feet, and we use the word “drilling” when we utilize larger rigs with large diameters for long crossings in the thousands of feet.

Join Our Team

When you join PWT, you become part of a community of people who are engaged in the most innovative practices in the Trenchless Industry. We have been instrumental in setting up a scientific method for cities to gain carbon offsets/credits from their use of trenchless construction. This system has been reviewed by the BC Government and has been approved as of December 2018. We expect to see it in common use shortly.
