Stop Digging. Start Rehabilitating.
Digging up driveways, concrete floors and gardens to repair damaged drainage systems can be disruptive, expensive and time-consuming.
At Utilimap Ltd, we use modern no-dig pipe rehabilitation technology to restore damaged drainage systems from the inside out.
Our specialist solutions include Cured-In-Place Pipe (CIPP) lining, internal spray and brush coatings, and localised structural patch repairs.
These innovative techniques allow us to repair and rehabilitate existing pipework with minimal disruption to your property or business.
Why Choose No-Dig Pipe Rehabilitation?
Minimal Excavation
Avoid unnecessary damage to driveways, paving, concrete floors and gardens. Our specialist systems allow repairs to be carried out through existing access points and manholes.
Rapid Turnaround
Most lining and patch repairs can be completed within a single day, helping to minimise inconvenience, disruption and business downtime.
Long-Term Structural Protection
Our WRc-approved resin systems create a durable, jointless ‘pipe-within-a-pipe’, providing structural strength and resistance to future root intrusion.
50-Year Guarantee
Our Core Pipe Rehabilitation Services
1. Multi-Kit® Localised Patch Repair
Targeted structural repairs for isolated drainage defects.
Our Multi-Kit® patch repair system provides an effective solution for damaged sections of drainage pipework without requiring complete pipe replacement.
The system is particularly suitable for:
- Isolated cracks and fractures
- Root intrusion
- Open or displaced pipe joints
- Localised structural holes and defects
How It Works
High-strength fibreglass matting is impregnated with specialist silicate resin and positioned precisely over the damaged section using an inflatable rubber packer.
Once inflated, the packer holds the repair material firmly against the internal pipe wall while the resin cures, creating a strong structural repair.
The system can cure in under two hours, allowing rapid completion and site handover.
Pipe Diameter Range: DN70 – DN250 (approximately 3” – 10”)
Typical Turnaround: 2–4 hours
2. Full CIPP (Cured-In-Place Pipe) Inversion Lining
Structural rehabilitation of complete drainage and sewer pipe runs.
Our CIPP inversion lining system allows entire lengths of damaged drainage pipework to be structurally renewed without the need for extensive excavation.
A resin-impregnated liner is installed inside the existing pipe and cured to form a new, seamless internal pipe structure.
Key Benefits
- Non-disruptive installation: Rehabilitates existing mainline drains and sewers without conventional excavation.
- Flexible installation: Suitable for pipe runs incorporating multiple bends and changes in diameter.
- Structural renewal: Creates a durable new pipe lining within the existing drainage system.
- Robotic reinstatement: Precision robotic cutting equipment restores lateral pipe junctions following the curing process.
This technique is particularly effective where longer sections of pipework have deteriorated or suffered structural damage.
Pipe Diameter Range: DN100 – DN300 (approximately 4” – 12”)
Typical Turnaround: 1 day
3. High-Speed Internal Pipe Coating & Milling
Specialist rehabilitation for smaller-diameter internal pipework.
Our internal pipe coating and milling service is designed for drainage systems where conventional excavation or pipe replacement would cause significant disruption.
This method is particularly suitable for:
- Vertical soil stacks
- Internal waste pipes
- Cast iron drainage drops
- Small-diameter drainage systems
Mechanical Pipe Preparation
Using specialist Picote mechanical milling equipment, we remove rust, scale, tuberculation and heavy internal deposits from existing pipework.
This process prepares the internal pipe surface for the application of a protective coating.
Dual-Pass Epoxy Coating
Once the pipe has been cleaned and prepared, a specialist epoxy coating is applied directly to the internal pipe wall using a brush application system.
The dual-pass application creates a smooth internal surface, helping to reduce future blockages and improve drainage performance.
Pipe Diameter Range: DN50 – DN100 (approximately 2” – 4”)
Typical Turnaround: 1 day
