Manhole to Manhole Rehabilitation Lining

EZ1 & EZ2 Liner Inversion Products

The EZ1/EZ2 Inversion Units uses water or air pressure, depending on the model, for inversion without the need of high scaffolds or lift trucks. The EZ1 model inverts with water only and the EZ2 model inverts with air or water. When using water, the EZ Series utilizes public water available from hydrants. A hot water boiler is then used to cure the liner. Gauges on the EZ Series are used to monitor and control the pressure(s) throughout the inverting and curing process.

Sanitary sewer systems across the country are showing signs of their age. Cracks and leakage in these systems can cause sewage to be diluted, increase the volume of sewage, and decrease the efficiencies of wastewater treatments.

So if your Florida plumbing or contracting business offers manhole-to-manhole rehabilitation lining services, PrimeLine Products, Inc. has a TRY TEK Controlled Water Pressure Inversion Unit that can help you complete your projects with reliable results.

The Challenges of Traditional Manhole Repair

Manholes, sewer, and stormwater systems are exposed to a lot, which can cause them to deteriorate and fail over time. Traditional methods of excavating and replacing them can be expensive, messy, time-consuming, and disruptive to communities.  

Traditional methods requiring big trucks and heavy equipment can also struggle to operate effectively under bridges and power lines, inside tunnels and alleys, and through backyards and smaller properties.

To avoid these problems, some operations have turned to steam curing or compressed air inversion to install liners; however, there can be risks associated with these methods, too. The high-temperature steam can melt or blister manhole liners and potentially harm the technicians carrying out the process. Additionally, continuous-feed air units may not always invert as far through a pipeline as water pressure inversion.

The PrimeLine Manhole-to-Manhole Rehabilitation Lining Method

Our manhole-to-manhole rehabilitation lining method can help limit these issues and more. The TRY TEK Controlled Water Pressure Inversion Unit uses a process called water inversion to limit the amount of water that enters pipes during your team’s manhole rehabilitation process. Your professional operators can inflate a pipe liner with pressurized water, provide a controlled amount of heat to the water as the resin-saturated liner hardens, and wait for the lining to successfully form. This cured-in-place process can run in excess of 1000 feet, easily navigate bends and irregularities in the host pipe, provide protection to the host pipe, and completely cure the pipeline with reliable results.  

Throughout the process, the TRY TEK inversion unit can help your team create a complete lining that should restore the system to a condition that’s essentially brand new.  

The Benefits of Manhole Lining

There are several reasons why your business should consider water inversion manhole-to-manhole rehabilitation lining over traditional repair methods:

  • Greater cost-efficiency. Repairing and lining existing manholes can help eliminate costs associated with excavating and restoring streets, properties, landscaping, and traffic areas.
  • Increased structural integrity. Lining manholes can protect them, solidify their interiors, and increase their life spans.
  • Easier operation. Water inversion should reduce lifts and soft spots so your operators can have greater control and maneuverability.
  • Higher reliability. The liner remains constantly inflated during water inversion, so the probability of host-pipe damages and cave-ins should be reduced.
