The GeoFuse™ geopolymer system is an advanced elastomeric, acid-resistant coating material that is designed to impart chemical resistance and self-healing properties to concrete and geopolymer surfaces. The waterproof protective coating is designed to extend the life of structures, bonding to nearly any surface including brick, rock, concrete, metal or wood.
The GeoFuse™ system provides a cost-effective option to replacement that allows owners and design engineers to extend the operating life of existing infrastructure assets and reduce total project costs. Designed for use in rehabilitation of pipes and structures for industry and private use, GeoFuse offers chemical resistance and self-healing properties to concrete and geopolymer surfaces.
Benefits and characteristics:
Two-part system that bonds to virtually any surface including: brick, rock, concrete metal or wood
Adapts to any shape that can be coated by brush, roller or trowel, including bends, curves, and angles
Resists cracking and peeling while expanding and contracting with the host surface

What are GeoPolymers?
Geopolymer is a term originally coined by French researcher Joseph Davidovits to describe a class of cement formed from aluminosilicates. While traditional Portland cement relies on the hydration of calcium silicates, geopolymers form by the condensation of aluminosilicates. The kinetics and thermodynamics of geopolymer networks are driven by covalent bond formation between tetravalent silicon and trivalent aluminum. The molar ratio of these key components along with sodium, potassium, and calcium have been shown to affect set-time, compressive strength, bond strength, shrinkage, and other desired properties.
In various parts of the world, this type of material is also industrially known as alkaliactivated cement or inorganic polymer concrete. Geopolymers are known to provide comparable or better performance to traditional cementitious binders but with the added advantages of significantly reduced greenhouse emissions, increased fire and chemical resistance, and reduced water utilization.
Are geopolymers a type of plastic?
No. When you see the term geopolymer for the first time, many people immediately assume the material will be a plastic like HDPE or polyester. While it is true plastics are polymers, not all polymers are plastics. So, instead of thinking of the materials you find in plastic bottles or food storage containers you should picture a material that behaves like cement.
If a geopolymer behaves like cement, is it actually a cement?
GeoSpray GeoPolymer Mortar has the look and feel of most standard cements. The geopolymer powder containing pozzolans is mixed directly with water to form a mortar just like standard cement materials. GeoSpray™ has been specially formulated for centrifugal casting of large diameter pipes, but processability and workability are similar to what you might expect from a cement mortar. You can think of GeoSpray™ as an advanced cement. Compressive, tensile and flexural properties of GeoSpray™ have been engineered to meet or exceed those you would expect from a cement formulation.
What are the advantages of a geopolymer over typical cement?
The major advantage of a geopolymer over typical cement mortars is that a geopolymer has the chemistry of an engineered stone. The aluminosilicate network that forms the chemical structure of GeoSpray is similar to the chemical structure found in natural stone, such as zeolites or quartz.
This stone-like chemistry is different than the hydration chemistry that is present in standard Portland and calcium aluminate cements, and creates a distinct advantage in chemical resistance. Additionally, unlike standard cement mortar, GeoSpray continues to react with itself for decades, building additional strength and enhancing its service life expectancy.
