P.W. Trenchless Construction Inc. offers a trenchless solution to your underground utility problems at a competitive cost.
Environmental concerns

The use of Trenchless Technology allows for the installation of required underground infrastructure with a much lower carbon dioxide release to the atmosphere.
The lack of open trench means less excavating no removal of native ground to dump sites and the required hauling of imported fill material for the trench. Trucks emission are kept to a minimum during Trenchless operations

PW Trenchless Construction has been active in writing and researching articles for various constrcution magazines. Trenchless Technology Magazine and Website offer a large amount of info on all trenchless technology.

The Earliest Trenchless technology was tunneling but pipe jacking has been used since the 1890's. Used under railroads, cast iron pipe was installed with the use hydraulic jacks. In the 1930 reinforced concrete pie with sizes up to 72 was installed via pipe jacking.

Technology from the oil fields was used to successfully install electrical utility cables during the late 1940's. Development of a machine with a wet boring device using hollow stem drill rods with a cutting head rotated by a oil drill rig.

The 1960's saw a new surge in trenchless technology as an effort was made to service all communities with utilities. By the 1980's many of these utilities were under sized and needed to be upsized and/or rehabilitated. Rehabilitating existing lines saw a surge in the 1970's and in most cases it decreased the capacity of the line. Internal spot repairs were developed to look after local problems. Pipe Bursting, a method of destroying the existing pipe while pulling through a newer and possibly large pipe was developed and used extensively. British Gas was one of the pioneers of this technology to service many older gas lines.

Micro tunneling was developed in the early 1970's and is similar to the system used to build the tunnel between France and England.

The mid 1980's saw steerable horizontal drilling and it's use at crossing under rivers and then in the 1990's used to install sewer mains on grade.

By Constant improvement and research many of these technologies are being utilised in many parts of the world, and are a huge step forward in the installation of utilities with the minimal disruption to the local community.

P.W. Trenchless offers pipebursting, sliplining and directional drilling, giving you an alternative to open cutting through sensitive areas. P.W. Trenchless Construction allows you keep trees, retaining walls, patios, and in some cases entire buildings untouched.
Even though it has only been in existence since January 2000, P.W. Trenchless Construction Inc. has one of the most experienced trenchless resumes in the province of British Columbia, because of it's personnel.
Trenchless Construction
We were
...the first to perform microtunnelling in B.C. in 1996, on Clark Drive for the City of Vancouver...
the first to install an extensive sanitary sewer system, 4500m by directional drilling at flat grades in Queensborough from 1994 to 1999 for the City of New Westminster...
the first to install a large diameter sewer (36" diameter) in Surrey, also on a flat grade in 1999 for the G.V.S. & D.D.
Pipebursting
We have been pipe bursting since 1996, completing our first work for the City of New Westminster. We have completed contracts for the City of New Westminster, Richmond, Delta, Surrey, White Rock, Vancouver, Victoria, Revelstoke, West Vancouver, Port Coquitlam and Burnaby; all of which have been successful.

We are active in the promotion of trenchless technology in that our president, Mr. David O'Sullivan, is a director of the NASTT-BC, the present Trenchless Technology group in B.C. and we actively support their efforts at education.
