Pourable Stone™
The chemistry of stone, made pourable.
What it is
The chemistry of cast stone.
Geopolymers are inorganic binders formed when aluminosilicate minerals react with an alkaline activator. Instead of firing limestone in a kiln, the reaction builds a dense, stone-like mineral network at low temperature. Poured into a mold, it sets into cast stone.

Compared
Different materials. Different chemistry.
| Property | Portland cement concrete | Wood framing | Pourable Stone™ |
|---|---|---|---|
| Made by | Limestone fired at ~1,450°C | Harvested and milled timber | Minerals activated chemically, no clinker kiln |
| Fire | Non-combustible, can spall | Combustible | Non-combustible, engineered for high-heat exposure |
| Rot, mold, termites | Not susceptible | Susceptible | Not susceptible |
| Acid & sulfate attack | Vulnerable in sewers and soils | Not applicable | Designed for resistance |
| Salt water | Steel corrosion from chloride ingress | Rot and marine borers | Designed for low chloride penetration |
| Ornament | Costly to form or carve | Hand-carved | Cast detail repeatable from one mold |
Performance claims for Pourable Stone™ are design targets pending independent testing. See Validation.

Our work began in the field, studying how ancient builders in the Americas shaped stone. That research informs a modern material.
