Structural Geopolymer Mortar

High-performance structural geopolymer mortar applied via centrifugal spray onto the internal pipe wall. Creates a new structural lining for geometries beyond CIPP's reach: large diameters, ovoid, rectangular shapes, and manholes.

Structural Geopolymer Mortar is a trenchless rehabilitation system based on the centrifugal spray application of a high-performance mortar. Unlike traditional concrete —which uses Portland cement— geopolymer is an advanced inorganic binder, formulated to withstand aggressive conditions such as sulfuric acid, sulfides, and severe abrasion, all common in sanitary sewer networks.

How it works:

The process is performed from an existing manhole, without excavation. First, the pipeline is inspected with a CCTV camera and deep-cleaned to ensure proper adhesion. Then, a centrifugal spinning spray head is inserted into the pipe and applies the mortar in controlled layers, distributing it evenly across the entire internal wall. The mortar sets in place, creating a solid, monolithic structural lining capable of performing as a stand-alone or composite system with the existing pipe.

Why Geopolymer Mortar:

Where CIPP reaches its limits —very large diameters, non-circular shapes, manholes, pumping stations— geopolymer mortar delivers a complete structural solution. Its compressive strength exceeds 60 MPa, and its chemical resistance makes it ideal for sanitary collectors where hydrogen sulfide rapidly deteriorates conventional concrete. Additionally, geopolymer has a significantly lower carbon footprint than Portland cement, aligning with sustainability criteria.

At TUBEPOL, we apply this technology with specialized equipment and certified personnel. We work with the leading geopolymer mortar systems available in the market, selecting the most appropriate one based on the technical, geometric, and chemical conditions of each project. We have delivered this solution to municipal collectors, industrial infrastructure, and large-diameter manholes across projects in Mexico and Latin America.
