Patch lining has all the benefits of drain liner
renovation, but is often used as an isolated repair
to a particular section of the drainage system.
Patch liner can be used to secure a fractured
drain or seal a root damaged pipe joint. This is
a very quick method of repair with a process
time of only 3 hours from start to finish.
The patch lining process begins by mixing the
resin and hardening agent together then applying
to the fibre glass patch.






The patch is then fitted onto an inflatable packer which
is sent down the drain to the defective area. Once in
place, the packer is inflated and the patch is set to the
walls of the pipe filling cracks and joints with resin.
Once cured, the packer is removed from the drain,
leaving the patch liner formed inside the pipe.










If a drain needs lining but there are lateral connections
from other drains such as gullies or toilets, lateral
cutting is usually the answer.
Prior to installing the liner lateral connection points
are identified and measured out. Once the liner has
cured we are then able to send our robotic cutter
down the drain to the located connection before
lining. The connections are then cut out using a
specially designed diamond blade on a robotic arm.
The cutter is controlled above ground by the engineer working in conjunction
with a CCTV camera unit, allowing us to view and control the cutting process.
