The Andidrain service goes beyond
investigation and cleaning, with a
comprehensive lining and patching
Often, the first sign to the customer of a drainage
problem is a blockage. This may have an underlying
cause, for example, root masses penetrating through
a broken pipe. Cleaning and cutting back the roots
will relieve the symptoms in the short term, but may
not cure the underlying problem. Left untreated, the
situation may present itself again and again, causing
further disruption and potentially more extensive
A further serious issue could be that of exfiltration,
where a damaged pipe causes effluent to escape
into the surrounding soils leading to the potential
contamination of groundwater and pollution. This
may also cause leaching away of the surrounding
ground structure, leading to further, more extensive
Customers may be concerned at the disruption that
digging down and replacing sections of broken pipe
can cause, but with a variety of no-dig (or
'trenchless') techniques now available, this need not
be the case.
Full Length Lining
Where defects are found to exist over a longer area of pipe,
a full-length lining is more likely to offer the most
Installed from manhole to manhole, a number of methods
are available depending upon the particular situation.
Lateral (side entry) connections are logged and reopened
using our own high performance robotic cutters.
Andidrain carry out Cured in Place (CIPP) lining works on
diameters from 150mm to over 1000mm.
Based on the ProKasro Ultra Violet (UV) cured system, the
Andidrain Lining Division are able to carry out lining using
state of the art equipment delivering effective results in a
fraction of the time taken by older and less environmentally
When compared with more conventional Water or Steam
Cured in Place Lining, UV offers the following advantages:-
• More Environmentally friendly - no Styrene odours and no
Styrene contaminated curing water to dispose of.
• No scaffold towers needed - more adaptable for locations
with height restrictions e.g. underpasses, tunnels, overhead
• Smaller working footprint needed on site.
• No large volumes of clean water needed, therefore no risk
of cross contamination via hydrants.
• Faster installation & cure.
• Less reduction in cross sectional area of host pipe, due to
glass fibre reinforcement allowing thinner liners.
• More gradient friendly and no risk of burst due to pressure
at laterals and downstream portals.
• Fewer access restrictions.
• No risk to personnel / public from steam or hot water
Where the problem is isolated to only one or two areas
within a pipe, the most cost effective method may be the
installation of a short length of lining to 'patch' the area in
Andidrain personnel are fully trained and we have carried out
many installations in the UK.
