Drain Relining & Patch repairs
A fast cost effective way to repair a damaged drain or sewer, no digging or excavating is needed. Relining a pipe involves inserting a liner impregnated with a special resin into the existing drain, it is then expanded with an air bladder and the and the resin laden lining bonds with the old pipe work to effectively give it a second skin It is as if you are fitting a brand new pipe inside an old existing pipe.
It is all carried out through the existing inspection chambers / manholes. Full lengths, half lengths or even individual sections can be installed. Bends, curves and offset joints are no problem for this flexible lining to negotiate and repair.
When re-lining is not an option, we are fully equipped & experienced to carry out the traditional methods of excavation and replacement.
The types of drainage our groundworks team can provide include:

Prevents tree root infestation
Patch lining is a cost effective, no mess, no disruptive time saving permanent & watertight solution, eliminating the need for costly & inconvenient dig ups.
It is ideal for repairing cracks, breaks, corrosions, root intrusion and open & displaced joints. The patch is spread out and infused with an epoxy resin before being wrapped around a pipe packer. The packer is then inserted into the drain up to the defective area before being inflated.
After an hour or so the resin cures and the packer can be removed. our drainage engineers have the knowledge and expertise to carry out the work professionally and efficiently.
What is a manhole?
A manhole is also known as an inspection chamber?
It is a covered opening that allows access to the drainage system for surveying, cleaning, unblocking or repairing the underground pipe work
If the cover or frame of a manhole becomes damaged or missing they can be unsightly and pose a safety risk.
They can also lead to damage to the drains that they are designed to protect.
For more information just give our office a call and we will be happy to help.
What is involved
First we remove the damaged cover and frame and safely protect the exposed areas. Clean all loose mortar from brickwork
We then put a fresh bed of mortar down and level the frame and make good the sides once that is complete
we instal a new fully compliant cover.
Not all cases need a complete fix sometimes just the manhole/inspection chamber covers just need placing
