Solve sewer and pipeline problems without digging or disrupting
Offers many specialist methods for even the most hostile
Safety and liability risks are minimal
Large cost benefits
The Lining Process:
lining system comprises of the inversion into the defective pipe
of a polyester felt tube which has a Polyurethane outer coating.
The liner is impregnated with a liquid resin which is chosen to
suit the situation in which the liner is to operate, and which is
designed according to individual specification for thickness.
For the defective pipeline in a manhole either the inversion tower,
or a Pressure water system is used to apply the head of water pressure
needed to invert the liner tube into the pipe. At points of access
along the sewer thermocouples are positioned to monitor curing temperature
along the liner.
When the liner is fully inverted, high pressure water is used to
propel the liner forward. After completion of inversion we deploy
the boiler from whence hot water is circulated to the temperature
required to cure the liner.
Most widely used trenchless method for restoring structural
integrity and removing infiltration from sewers.
This method results in a seamless, joint less "pipe-within-a-pipe"
with a smooth, continuous inner surface which increases flow capacity.
The benefits of using CIPP lining system
It can be quickly installed without excavation causing minimal
Forms a structural and durable new pipe within the old pipe
Bridges and seals gaps, holes, cracks etc.
Eliminates infiltration from joints
Resistant to chemical attack and corrosion
Forms to any shape of pipe and bends
Improves the carrying capacity and flow characteristics
Used for cleaning or jetting the sewer. Using high pressure jet
of water to clean the sewers, followed by sucking out the sludge
by vacuum extraction before installation of the lining.
The CCTV Survey:
Prior to the installation the sewer line is inspected using a CCTV
camera. This is to ensure that the pipeline is free of silt, debris,
tree-roots or intrusions, which could adversely affect the lining
With a range of cameras able to survey and record information from
pipe sizes 75mm to 2000mm the EOL CCTV survey division has already
completed over 100s of kilometers. The CCTV van is made to our specifications
to suit our projects.
