In view of the global trend toward rebuilding the world's infrastructure, the demand for high performance lightweight aggregate is growing. The rugged durability and outstanding performance record of STALITE Lightweight Slate Aggregate make it the clear choice for meeting or exceeding the design and engineering parameters for buildings, bridges, highways and horticultural applications around the world. Our goal is to provide the highest quality and most consistent material possible to our customers.
STALITE's strong end-use products begin with the production processing of our raw material slate. Slate possesses the high strength and lasting durability necessary to create a superior lightweight aggregate. Unlike shale or clay deposits formed from mineral or organic sediments, the slate used in STALITE was formed from volcanic ash. This volcanic ejecta, free of impurities which were burned away at very high temperatures, was deposited in a wet environment and compressed under extreme pressures for millions of years.
STALITE is a cost effective alternative to soil or heavyweight fills in geotechnical applications. Because of its lower weight, about 50% of normal weight fills, STALITE reduces lateral pressures so that more economical retaining walls can be utilized. Dramatic saving in transportation and placement costs can be achieved since trucks and other equipment can be safely filled to capacity without exceeding weight limits or increasing wear. STALITE's high angle of repose provides very stable, long-lasting geotechnical fills, capable of supporting heavy, repetitive loads.
