At Manhole Lining, we specialise in rehabilitating underground manholes to enhance structural integrity and prevent water infiltration.

Our professional solutions involve applying durable coatings or liners, extending the service life of manholes while reducing maintenance costs.

Ideal for municipal wastewater systems, industrial sites, and stormwater management in Northfleet and across the UK, our methods comply with environmental standards, providing long-lasting protection against corrosion and leakage.

What Are the Benefits of Manhole Lining?

Manhole lining significantly extends the lifespan of deteriorated structures by reinforcing load-bearing capacity and preventing corrosion. It keeps groundwater out and ensures that wastewater remains contained, reducing the risk of contamination.

Since lining requires no excavation, it minimises disruption to roads and services. Additionally, it improves safety by reducing the chance of structural collapse. Cost-wise, lining is more affordable than complete replacement, making it a practical investment for maintaining wastewater infrastructure.

What Are the Most Common Manhole Lining Methods?

The choice of manhole lining method varies according to corrosion levels, structural integrity, and expected lifespan, which include:

• Epoxy lining – Involves applying a thick, chemical-resistant coating, ideal for wastewater environments prone to corrosion.
• Polyurethane or polyurea lining – Sprayed to create a flexible, seamless layer, useful in manholes with slight movement.
• Cementitious lining – Uses a cement-based mortar to restore structural stability, particularly in older, deteriorated manholes.
• CIPP lining – Involves inserting a resin-impregnated liner, which cures to form a load-bearing structure.
• Spray-applied polymer lining – Quickly forms a protective barrier, suited for minor surface imperfections.

How Much Does Manhole Lining Cost?

The cost of manhole lining, such as epoxy lining, ranges from £200 to £400 per vertical metre; polyurethane or polyurea, from £300 to £600 per vertical metre; and cementitious lining, from £100 to £250 per vertical metre.

Additional costs may include CCTV inspection, cleaning, and minor structural repairs. Despite the initial expense, lining offers long-term savings by reducing maintenance and prolonging manhole life.

How Is Manhole Lining Installed?

The process for manhole lining begins with an inspection and assessment using CCTV surveys to detect cracks, corrosion, and infiltration points. The next step is cleaning and surface preparation, which includes high-pressure water jetting and abrasive blasting to remove debris.

Structural repairs follow, addressing cracks and stabilising loose materials. The chosen lining system is then applied, often with priming to ensure adhesion. Once applied, the liner undergoes curing and post-installation testing to verify leak resistance and structural integrity.

How Long Does Manhole Lining Last?

The lifespan of manhole linings, such as epoxy and polyurea linings, lasts 25-50 years, while cementitious linings last 15-30 years. CIPP liners can last up to 50 years.

Factors affecting durability include chemical exposure, flow intensity, and the quality of surface preparation. Regular inspections and minor repairs help sustain the liner’s protective qualities over time.

What Are the Typical Applications of Manhole Lining?

Manhole lining is essential for various applications, including:

• Sanitary sewer systems – Prevents inflow and infiltration (I&I), helping maintain wastewater containment.
• Stormwater manholes – Protects against sediment buildup and chemical exposure.
• Industrial and commercial sites – Manages chemical runoff and ensures wastewater containment.
• Water treatment facilities – Protects concrete structures from harsh chemicals.
• Culverts – Prevents erosion and maintains structural stability.

How to Maintain Lined Manholes?

Proper maintenance of lined manholes involves routine inspections using CCTV to check for liner integrity. Jet cleaning removes sediment and debris that can impair function.

If small cracks or blisters are detected, patching should be carried out immediately to prevent escalation. Annual professional assessments ensure that the lining remains effective under high-flow conditions, maintaining structural safety.
