GeoTree Solutions has launched a new product which will make relining sanitary sewers and aggressive industrial pipelines, a one step process. GeoSpray® HCE (Highly Corrosive Environments) is a new addition to the GeoSpray range of geopolymer mortars that are hand or spray cast to form a pipe within a pipe.
The material, which sets stronger than concrete, has relined culverts, pipes, utility vaults, manholes, water/processing tanks, tunnels and irrigation channels and is proven to last for decades, and improves the structural strength of the original material.
HCE has been engineered to withstand the corrosive environments of sewers, areas storing or transporting industrial water, manholes, wet wells, wastewater, lift station tanks and containment areas (pH < 2.0 and high H2S environments).
GeoSpray HCE was developed to replace GeoTree’s 10-year-old AMS system which required the application of the standard GeoSpray mortar following by a post coat which minimized the surface penetration of corrosive fluids.
GeoTree Solutions President, John Hepfinger explained the reason HCE was developed: “As part of our efforts to improve every day we are always looking for ways to make our solutions more impactful and contractor friendly. While AMS worked very well, our partners indicated they would like to get everything all in on package. HCE eliminates the second step required with AMS, saving on time and labor.”
GeoSpray HCE has received certification to German Standard DIN 19573 XWW4 which is the most widely recognized and strictly controlled testing protocol for sewer corrosion.
GeoSpray geopolymer is a fiber reinforced mortar that looks and feels like Portland cement, but with higher performance properties. Unlike other cementitious liners, the unique GeoSpray mortar chemistry provides superior flexural and compressive strength, as well as ultra-low porosity and high self bonding which eliminates cold joints. GeoSpray geopolymer is intended for use through multiple application techniques including pouring, troweling, spraying, or centrifugal/spin casting.
