Teretek®
Mainmark helped Tata Steel eliminate water ingress affecting a critical industrial pipeline at Port Talbot using its proprietary Teretek® resin injection technology. The solution sealed active ingress pathways, prevented further water penetration and protected the asset from ongoing deterioration without the need for major excavation or replacement works.
Completed in just five days, the project restored confidence in the long-term performance of the pipeline while allowing site operations to continue uninterrupted.
The Challenge
Water ingress was occurring through a large-diameter industrial pipeline, creating operational concerns and the potential for ongoing deterioration of surrounding infrastructure. The source of the ingress needed to be identified and sealed quickly to prevent further water penetration and avoid disruption to site operations.
The client required a rapid, non-disruptive solution capable of sealing ingress pathways and protecting the asset without extensive excavation.

The Solution
Mainmark carried out a detailed site assessment to identify likely ingress points and determine the most effective treatment approach.
Using 2,150kg of Teretek® material, the team injected expanding geopolymer resin into the affected area, where it:
Filled voids and water migration paths
Created a dense, impermeable barrier
Sealed active water ingress pathways
Protected the pipeline from further water-related deterioration
The treatment achieved effective remediation without major excavation, asset replacement or interruption to ongoing site activities.
The Results
Mainmark successfully eliminated water ingress and protected the pipeline from further deterioration.
Project Outcomes
Installed 2,150kg of Teretek® material
Successfully stopped water ingress into the pipeline
Completed works without major excavation
Avoided disruption to site operations
Protected critical infrastructure from ongoing deterioration
Extended the service life of the existing asset
Verification following treatment confirmed that water ingress had been successfully arrested, with no further evidence of active water penetration.
Key Benefits
Water Ingress Eliminated
Created an impermeable barrier that prevented further water penetration into the pipeline system.
Minimal Disruption
Delivered a rapid solution without major excavation or interruption to operational activities.
Extended Asset Life
Protected critical pipeline infrastructure and avoided the need for premature replacement.
Lower Environmental Impact
Retained the existing asset and avoided the material consumption, waste generation and environmental impacts associated with more invasive repair methods.
Expert Insight
"The water ingress affecting this critical pipeline required a solution that could be delivered quickly, safely and with minimal disruption to ongoing operations. Mainmark's Teretek® injection methodology successfully sealed the ingress pathways, filled associated voids and restored confidence in the long-term performance of the asset without the need for extensive excavation or replacement works."
