CHALLENGE

Existing 1350 mm diameter CSP culvert under

Bathurst Street had deteriorated under 6

lanes of roadway. This culvert went from an

existing maintenance hole to the ditch at

Bathurst Street and Teston Road. The ditch

at the outlet end was going to be filled as

part of the reconstruction of Teston Road

and a new catch basin added to connect the

outlet of the pipe to be direct buried.

SOLUTION

Line the CSP with 1016mm diameter HDPE

Weholite Pipe and extend the liner an

additional 20m to be direct buried and

connect to the new catch basin.

PROJECT OVERVIEW

The access to this culvert was restricted on the

east end as access was through the

maintenance hole in the shoulder. The project

was a success and was completed in less than

one week. Terrafix Geosynthetics Inc. provided

drawings and burial calculations to the engineer in

charge and worked closely with the owner and

contractor to ensure that the project went well.

At Terrafix, we provide powerful new technologies in geosynthetic

products and services for construction and environmental applications. These new technologies can save you installation time and money.... and we can prove it!

Weholite Pipe meets the design criteria for direct bury

pipe and can be used for storm and sanitary sewer

applications as well as sliplining applications. For

sanitary sewer applications we can offer a leak-free

system which will save you money by lowering

treatment costs as well as lowering maintenance and

repair costs. Leak-free systems are achieved by heat

extrusion welding the joints of the Weholite HDPE Pipe.

Currently, Weholite Pipe is being used in low pressure

applications at the Lou Romano Wastewater Treatment

Plant in Windsor Ontario.
