Do you know Trenchless Technologies (no-dig) with plastic pipes?

1) DRIVEN DRILLING. At present it is being used horizontal driven drilling with PE pipes up to 1200 mm diameter and over. It is ideal to overcome obstacles and existing services.  It allows junctions at different depths always working in the surface. It is used for any type of service. […]

Why using Trenchless Technologies (NO-DIG) with plastic pipes. IbSTT

Pipes, as well as building facades, need to be rehabilitated within a few years. Between 25% and 40% of existing pipeline networks in Europe need to be rehabilitated, to avoid causing damage to human life and environment. […]

Second part of the interview to Domènech Pintó, manager of Catalana de Perforacions

. . . continuation of the previous post. In which applications can have higher use the No-Dig Technologies? The first thing to take into account is that during the last 50 years it has been developed in the city countless of canalizations, collectors and drainages. Formerly we were used to see how it was installed on the surface the poles of telephone lines, the electrical wires, the high voltage towers, etc., while now the tendency is to bury all these kinds [...]

First part. Interview to Domènech Pintó, manager of Catalana de Perforacions

“The Trenchless Technologies offer very efficient technical solutions” This post is based on the interview that David Muñoz of Interempresas.net did to Domènech Pintó on the 21st October, 2014 and that according to its content I have considered interesting to include it in Blogplastics. […]

The punctual reparations of the pipe will be normally executed by opening a hole in the damaged spot and repairing the pipe from the exterior. In under certain circumstances it can’t be accessed to the spot in question for several reasons, because it is under a railway, an important highway, a building, etc. so it must be repaired without the opening of such hole, that is, it must be repaired from the internal side of the pipe itself el interior.

• Fittings for outlets Instead of using metal fittings or expensive reduced tees, it is already possible to perform PE outlets for suckers or other elements of the network both in the shop and in work, such as it is seen here. It is important when we want to do an outlet from a huge PE diameter. […]


We remember you that the System Standard EN 12201 specifies the general aspects of the system of channelling at pressure of polyethylene (PE), main and service systems, for buried and aerial applications, intended to water supply for the human consumption, including the water before subjection it to treatment, the sewage and sanitation at pressure, the systems of vacuum sanitation, and the water intended to other uses and it is applicable to PE pipes, fittings and valves, its joins and joins with [...]

Sea transport of PE pipes of huge lengths and diameters

It was 1990 and in June Uponor, which had bought Resiplast, invited to some technicians to visit its Company situated in Stathelle in the south of Norway which manufactures pipes in huge length and diameters, that exit directly to the fjord that were next to them and where they were “stored” for their following transport towed by a ship to other countries like UK, Ukraine or Brazil. […]

IbSTT- Iberian Association of NO-DIG Technologies

For a City without Digs The IbSTT (Iberian Society for Trenchless Technologies) is a scientific-technical and non-profit association, which was constituted on the 16th July 1995 with the aim of promoting “techniques without digs”. The Water and Gas Services when perform new installations or replace the existing networks, they often find access restrictions in roads, streets, highways or spaces that are continuously occupied. More and more the use of the No-Dig Technologies without the opening of a trench is solving these [...]
