STARcrete™ is a sulfur-based concrete with unique properties.
Impermeability, corrosion resistance and lack of fatigue are its outstanding characteristics.
The water absorption of test cylinders is normally less than 0.1% and often below 0.05%.
When subjected to many common liquids, STARcrete™ exhibits a significantly lower degree of breakdown than Portland cement concrete.
Tests have been conducted comparing the durability of STARcrete™ and Portland cement when exposed to
different liquids and influences such as freeze/thaw and fatigue.
