Pipe Rehabilitation


The Smartest Way to Rehabilitate Pipes

Pipeline rehabilitation is a hot topic as rust, leaks and earthquakes result in old pipelines being damaged. They also need to be repaired to meet new regulations. While the old pipelines are often still functional and may provide desired levels of water pressure, they have some negative side effects. Long-term effects can range from soil contamination to city gas explosions. Our rehabilitation liners can be used for all leaking transfer pipes, whether from drinking water, methane gas, sewage, or industrial chemicals. Installing the liner is done via pull-through. This ensures guaranteed service life and the existing pipe remains in place. Before installation, a regular clean-up of host pipe has to be done; use Polly Pig or other caterpillar tools.

The main advantage of our pipe renovation liners is that it drastically reduces downtime. You don’t need to invest in new pipes or disrupt traffic with endless excavation works. Leaks and corrosion are stopped and water quality is improved. The liner is flexible in terms of the diameter variation of the original pipe, and it easily passes sharp bends even at longer lengths.
