Lining & Excavating
There are two options for Brighton drain repair: lining and excavation.
Drain lining does not require extensive work to extract the
former drain structure. Instead a new drain is laid within the
existing drain, using it as a guide and adding futher support to
the existing drainage structure.
Drain Lining - no dig repairs without
excavation.
Localine - Where defects are localised in a small area of
the drain, this can be "patched" to produce a permanent high
quality drain 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.
The benefits of lining as a drain repair solution are:
- Minimal cost
- Minimal disruption and inconvenience
- Resistant to leaks or root penetration
- Minimal cross section loss
- Speedy return to full function
- Suitable for all types and sizes of pipework from 75mm diameter upwards
Drain excavation requires full excavation and removal of the existing drainage system and replacement with new materials. Drain excavation is normally used to:
- replace short sections of pipe at a shallow depth, or for:
- a collapsed or structurally defective pipe which cannot be repaired using any of the No-Dig techniques listed.
