DRAINAGE REPAIRS & PIPE RELINING
Drain Repairs
Repairing and renovating
drains can now be done with the minimum of cost and
disruption. We have available a range of alternative, cost
conscious solutions in addition to excavation. |

Why drains need
repairing - Drains and sewers may crack due to ground movement,
subsidence, tree root infiltration, or corrosion - or they may
totally collapse. The result is a structurally defective drain
causing repeat blockages or leaks into the surrounding soil.
Finding the most effective, cost conscious repair solution -
Whatever the problem, the most appropriate solution can be
determined via jet flow's CCTV Surveying Service. This will
detect the nature and extent of any structural fault, which will
in turn assist the engineer in recommending the most appropriate
repair technique.
Different Methods Of Drain
Repair
Excavation - Normally used to:
a) replace short sections of pipe at a shallow depth or
b) a collapsed or structurally defective pipe which cannot be
repaired using any of the
No-Dig techniques listed below.
No-Dig (repairs without excavation)
Where defects are localised in a small area, this can be
"patched" to produce a permanent high quality repair. Patches
are applied by coating a fibre-glass mat with epoxy resin. The
mat is then wrapped around an inflatable packer and pushed into
position. The packer is inflated and the resin left to cure.
Section Lining - Where the drain is damaged along its length,
the whole section can be lined. It involves the insertion of a
lining "sock" impregnated with a polyester resin fibre along the
length of the damaged drain. It is then moulded into place using
air or water pressure and left to cure. The result is a new
fibre reinforced pipe within the old damaged pipe.
