Trenchless – Pipes Rehabilitation

INTRODUCTION

Trenchless technology uses non-disruptive pipe repair methods that do not require digging or breaking the host pipe.

All work is carried out inside the piping by qualified personnel with specialized machinery representing the best house worldwide.

NO-DIGGING pipe repair is an innovative but at the same time 100% successful method with multiple benefits, compared to conventional ones that require deep excavations, breaking, damages to surrounding facilities, traffic disruption, high costs, and environmental destruction.

The main benefits of this method are that there is no disturbance in the repair areas from unnecessary damages, noise from breaking and digging, short execution work time, and a small environmental footprint.

In addition and also important, by choosing to repair the damage with this particular method, we do not need to call a second or third professional workshop to complete the work, such as repair of cracks, backfilling of excavations, or repair of excavated cover surfaces.

HOW DOES IT WORK

1. INSPECTION WITH ENDOSCOPIC CAMERAS (CCTV)

Without trenches digging and breaking surface covers, we use endoscopy cameras of a Closed Circuit TV system of the latest generation – high resolution for an accurate result.

2. PROBLEM IDENTIFICATION

We locate the problem at the exact point of damage and not approximately, as a result of which we save time of repair.

3. DUCT CLEANING

We clear the pipeline of any obstruction, facilitating the flow in all types of pipes, quickly and efficiently.

4. USING THE REPAIR CURE IN PLACE PIPE (CIPP) METHOD

The world’s most flexible NO-DIGGING duct repair system. It provides waterproofing and extra resistance against wear and corrosion.
