Geopolymer Lining
Restoring Large-Diameter Infrastructure from the Inside
Geopolymer spray lining provides a powerful trenchless solution for rehabilitating large-diameter sewer and stormwater systems. Spiniello installs structural geopolymer liners that restore deteriorated pipelines while extending asset life and minimizing disruption.

Designed for Large-Diameter Rehabilitation
Many aging sewer and stormwater systems suffer from corrosion, structural deterioration, and infiltration that threaten long-term performance.
Geopolymer spray lining restores these systems by applying a structural coating that bonds to the existing pipe surface filling cracks, voids, and deteriorated areas while rebuilding the pipe wall.
Spiniello has extensive experience installing geopolymer liners in large-diameter infrastructure ranging from 36 inches to more than 240 inches, helping municipalities restore critical interceptor systems while avoiding costly pipe replacement.

Comprehensive Geopolymer Installation Approach
Successful geopolymer rehabilitation requires precision, preparation, and experience working within large-diameter systems.
Spiniello delivers end-to-end geopolymer solutions designed to ensure structural performance and long-term durability.
Our structured approach includes:
System Preparation – Cleaning and surface preparation to ensure proper bonding
Surface Rehabilitation – Addressing voids, cracks, and deteriorated areas
Geopolymer Application – Controlled spray application for consistent coverage
Thickness & Structural Control – Achieving required structural design parameters
Curing Process – Rapid strength development for efficient project timelines
Inspection & Quality Control – Verification of lining integrity and performance
This process ensures consistent results across complex, large-diameter infrastructure systems.

Advanced Materials for Long-Term Performance
Geopolymer materials offer a durable alternative to traditional cement-based rehabilitation methods.
Produced from minimally processed materials and industrial byproducts, geopolymer provides exceptional resistance to corrosion and chemical attack making it well suited for harsh wastewater environments.
Key advantages include:
High structural strength for large-diameter applications
Resistance to corrosion and chemical degradation
Rapid curing, often achieving significant strength within 24 hours
Sealing of cracks, joints, and voids to reduce infiltration
Extended service life of 50+ years
These properties make geopolymer an effective solution for restoring critical interceptor systems.

From Evaluation to Execution
Geopolymer lining is most effective when applied as part of a broader infrastructure strategy.
Spiniello evaluates pipeline condition, hydraulic performance, and structural requirements to determine whether geopolymer is the right solution and how it should be applied for optimal performance.
Because we perform multiple rehabilitation methods including CIPP, cement mortar lining, sliplining, and pipe bursting, we help asset owners select the best approach for each system.
