No-Dig technical Guide

Welcome to the Online Guide to the use of Trenchless Technology for installation of PE100 pipes.

This Guide has been developed by the PE100+ Association and co-sponsors TEPPFA, Exova, Radius Systems and Downley Consultants with the purpose of enabling users, designers, specifiers and decision makers to make use of the full range of trenchless technologies to install PE100 pipe either as new pipe or for rehabilitation and replacement of existing underground pipes.

The Guide will identify the properties, benefits and applications of PE100 in trenchless techniques for use by designers and decision makers and will enable you to decide which methods are applicable to a specific project.

PE100 pipe is central to water and gas distribution systems in many regions of the world. PE100 is approved for these applications and is the preferred pipe material in small and medium diameter pressure networks for customers in many countries. PE100 is also ideally suited for use with a range of trenchless technologies. Whether new installation, rehabilitation or replacement of existing mains, trenchless technologies are often the most efficient and cost-effective, and least disruptive, methods to use. In all of them the objective is to have a PE100 pipe in the ground carrying water, gas or wastewater safely and efficiently.

This Guide will help you to decide whether trenchless techniques could be used to install PE100 on a specific project, which ones could be used most effectively, and what key points need to be considered in deciding which technology to specify and use. The Guide includes a decision process to identify applicable trenchless methods based on project parameters as well as descriptions of all the methods and their practicalities. Links are included to manufactures of materials, components and equipment for further information where you may need it.

This is not a design guide. When considering decisions on specific projects the user will need to undertake a design based on hydraulic (or gas) capacity requirements in order to establish the diameter and pressure capability of the PE100 pipe. These two design results will be used as input data to the decision process in this Guide which will lead to solutions showing how the design requirements can be met with PE100 and trenchless technology.

Using the guidelines

You can use the Trenchless Guidelines in one of two ways. Firstly as an informative tool by browsing through the list of Trenchless Methods. This route contains the information for you to assess for yourself whether a method is applicable to your needs. Alternatively by selecting the Design and Decision route you will be led through the design requirements and input process to gather your project specific and other relevant data. Through this route you will be guided by our tool to the trenchless methods which may be applicable for your project.
