DRAINS - DRAIN LINING (NO DIG TECHNOLOGY)
No Dig Technology is a proven and established method of placing a new pipe within an existing
damaged pipe without excavation and with minimal disruption.
|
CCTV inspection can locate
a number of reasons that causes pipe
failure including leaking
and open joints, root intrusion and
cracks
|
|
The new pipe material
is similar to GRP (glass reinforced
plastic)
and in all cases will be superior in
quality
and strength to the pipe which it
lines. The
new pipe is moulded into the damaged
pipe by
an ingenious method called 'inversion'
using
water or air pressure, fitting it
tightly against
the wall of the existing pipe. When
the inversion
is complete the new pipe (which is
originally
flexible) is now rigid, resulting in a
strong,
tough pipe tightly fitted within the
existing
pipe with only a minimum loss of cross
section
of approximately 6%.
The liner is manufactured
from a special dense impermeable felt
and is
designed and tailored to fit exactly
the internal
dimension of the pipe to be
refubished. The
thickness of the lining material can
be varied
according to design specifications
required.
We have a selection of three special
resins
systems - Polyester, Silicate and
Epoxy with
different curing times - suitable for
various conditions and applications.
These are
impregnated into the liner
prior to
installation in the pipe. The
liner is
suitable for sewers and vertical
rainwater down pipes etc, 75mm -
300mmØ.
It is resistant to most
aggressive chemicals
and can withstand extremely high
temperatures.
A special resin containing an
activating catalyst
is impregnated into the pipe liner prior
to installation.

lining is

The liner is resistant to most

and can withstand extremely high
temperatures.
Once the pipe is cured,
the inversion liner is removed
leaving a strong and tough new
pipe within the existing pipe. Any
lateral pipes are reconnected
by a remote controlled robotic
cutter.

A new liner is
first impregnated with a special
resin containing an activating
catalyst before being winched
through the damaged section
|
|
An inflation hose is inverted
into the new liner by air or water
pressure
|
|
This shapes the liner into
the existing pipe and holds it in
position while it cures. Hot
water or steam can help control
the curing process

THE
ADVANTAGES OF NO DIG TECHNOLOGY.
|
|
The
customer will benefit in many ways.
- Eliminates
costly excavations and general
disruption
to the property.
- Capable of
repairing
and curing leaking and open joints,
root
intrusion, cracks and all other
associated
pipe failure.
- Suitable for
domestic,
industrial, commercial and municipal
applications.
- Achieves
permanent
structural repair.
- Guarantees improved
flow
characteristics.
- Will
withstand
ground movement far in excess of
traditional
drainage materials such as saltglaze,
clayware,
concrete etc.
- Any
cross-sectional
loss is adequately compensated by
increased
flow efficiency.
- The process
is
accepted by Local Authorities, Loss
Adjusters,
Surveyors, Civil Engineers and
Architects
etc.
- Continual
lengths
of up to 100 metres can be installed
in
one length.
- Minimum
lengths
of 0.5 of a metre can be installed for
a
local structural repair.
- The materials
used
are extremely strong, abrasive
resistant
and do not rely on the existing pipe
for
its structural integrity.
- A drain
liner
refurbishment
will be ready for use within hours of
installation.
- Very cost
effective,
up to 75% savings have been achieved
by
drain lining over conventional methods.
- Superior
quality
at lower cost means good value for
money. The drain liner we use (Renoline)
conforms with European Standard
BSEN13566-F:2002.
