why cement mortar lining
A Time-Tested Approach to Pipeline Renewal
Cement Mortar Lining has been used since the 1940s as a reliable method for restoring and protecting water pipelines. The process creates a protective lining inside the pipe that shields against corrosion, reduces internal buildup, and improves hydraulic performance.
For asset owners facing aging infrastructure, CML provides a cost-effective way to extend pipeline life while avoiding the disruption and expense of full pipe replacement.
Spiniello has installed millions of feet of cement mortar lining throughout its history, applying the technique across water systems nationwide.

Comprehensive Rehabilitation Across Pipe Types and Sizes
CML is a versatile solution that can be applied across a broad range of pipeline materials and diameters.
Spiniello’s specialized equipment and experienced crews allow us to rehabilitate systems including:
Steel
Cast Iron
Brick
Concrete
Asbestos-Cement
Wood Stave
Corrugated Metal
Our structured approach includes:
System Preparation – Cleaning and surface preparation to ensure proper bonding
Lining Application – Controlled placement of cement mortar for consistent coverage
Reinforced Lining (when required) – Structural support for large-diameter systems
Curing Process – Ensuring strength development and long-term performance
Inspection & Quality Control – Verification of lining integrity and system readiness
We have successfully rehabilitated pipelines ranging from 4 inches to more than 22 feet in diameter, including large transmission systems where maintaining flow and structural integrity is critical.

Restoring Performance and Protecting Infrastructure
Corrosion and internal buildup are among the most common challenges facing aging water systems leading to reduced flow, leaks, and increased operating costs.
Spiniello’s Cement Mortar Lining process restores pipeline performance by creating a durable internal barrier that:
Protects against corrosion and internal deterioration
Restores hydraulic capacity and improves flow
Extends the service life of existing pipelines
Reduces long-term maintenance and operating costs
For larger systems, reinforced CML applications can also provide additional structural support while maintaining high-pressure performance.
