Sewpercoat® - Other Installation Methods

Besides the usual low pressure wet spray and high-pressure dry spray methods, SewperCoat® can be installed in other specialty applications (like as a pipe lining for example) through various methods.

  • The centrifugal lining process and the spinning process are typically used to install SewperCoat® in ductile iron and steel pipe.
  • The bi-directional packerhead method is used to install SewperCoat in large diameter concrete pipe.
  • The ROCLA process is another method to apply a cement mortar lining inside a concrete pipe.
  • SewperCoat® can also be batched and mixed in large quantities and wastewater shapes, like manhole and lift station sections, can be traditionally formed and cast.

Have a look to the slide show to the right to see some examples of these installation methods.


On-going centrifugal lining of ductile iron pipe. SewperCoat® mortar is fed inside the rotating pipe by a moving head and the centrifugal force spreads it evenly on the inner surface. The centrifugal force also expels some of the mix water, making the mortar even denser and more resistant to corrosion.

Mechanical resistance test on bi-directional packerhead concrete pipe internally lined with SewperCoat®. Note that SewperCoat® has been dyed red for this test to facilitate the observation of the lining.

Concrete pipe made with the ROCLA process with an internal protection lining of calcium aluminate mortar. SewperCoat® can be applied by the same process if biogenic corrosion conditions call for it.

Example of precast manhole sections cast with calcium aluminate concrete. For very severe biogenic corrosive environment, such equipment can be cast with SewperCoat®.
