MAIN FEATURE


Globally, around 15,000 km of CIPP is installed per year at a value of $3.5 billion!


To date, starting from the first installation 50 years ago, over 200,000 Km or 125,000 miles has been installed worldwide. This length is the equivalent of 5 laps around the planet!


associated with trenchless work, particularly when working near existing infrastructure.


4. Basic Construction Skills: Familiarity with general construction practices, including excavation and backfilling, is essential for workers engaged in trenchless projects.


High-tech trenchless technology incorporates advanced methodologies and sophisticated equipment, providing greater precision and efficiency. Notable high-tech trenchless methods include:


1. Microtunnelling: This technique uses a remotely controlled microtunnel boring machine (MTBM) to excavate a tunnel. It is suitable for installing large- diameter pipes in urban areas with minimal surface disruption. Microtunnelling is characterised by its ability to navigate complex underground conditions.


2. Directional Drilling: Also known as horizontal directional drilling (HDD), this method employs a guided drilling system to install pipes beneath obstacles. It is widely used for installing telecommunications, gas, and water lines across various terrains.


3. Sliplining: This technique involves inserting a new pipe into an existing one. Advanced technologies, such as robotic cameras, are often used to inspect and prepare the existing pipe for sliplining.


4. Cured-In-Place Pipe (CIPP) Lining: CIPP lining is a trenchless rehabilitation method for existing pipelines. A
