The GeoSpray® geopolymer system is made of a high-performance, fiber-reinforced geopolymer mortar, specifically formulated and engineered as an environmentally friendly solution for rehabilitating pipes, culverts, and containment areas.
Unlike other cementitious mortars and grouts, GeoSpray® spray-applied liners help create a new structural pipe within the old pipe. This process requires no digging - virtually eliminating traffic delays - and is fast to install. Using GeoSpray®mortar improves performance and strength and is less costly than alternatives, including SPR, CIPP, and slip-lining.
GeoSpray® geopolymer mortar is ideal for the rehabilitation of large diameter pipes and structures in Civil Infrastructure and Industrial applications. It is the first geopolymer mortar specifically designed as a structural and corrosion-resistant solution for large diameter storm and sanitary pipes, manholes, wet wells, and treatment plant structures.

More about Geopolymers
Dating back to the earliest historical uses of cementitious formulations as building materials, society has looked for ways to use the wide variety of available raw materials to improve the physical properties of the final products.
Evidence of the inclusion of volcanic materials such as volcanic ashes by the ancient Greeks dates back to at least 500–400 BC. As early as the 1920s, cement formulators have employed refined industrial byproducts such as fly ash, metal slag and processed silicas, collectively referred to as pozzolans, as fillers and aggregates in standard cements. Today, almost all cement formulations contain some percentage of these natural or manmade by-products.
It has long been know that these pozzolans undergo chemical reactions with standard cement materials that improve properties, such as compressive strength, and bind materials like calcium hydroxide, Ca(OH)2, enhancing the resistance to chemical corrosion.
In the early 1970s a French scientist, Joseph Davidovits, discovered that under the right set of conditions these components could fully react with one another to form an extended polymeric network primarily made of Aluminosilicate bonds (Al-O-Si). He coined the term geopolymer to refer to this new class of materials.
Since that time, engineers and scientist around the world have worked to develop commercially viable geopolymer solutions for a wide variety of industrial applications. GeoTree Solutions has developed a state-of-the-art geopolymer mortar – GeoSpray® - that exploits the physical and chemical advantages of geopolymeric materials in a form that is easy to use and employ in the field.
