For modern civil engineering needs, excellent soil stabilisation can be achieved with Proctocal® products from Calcis. Wet soils are compacted and protected against frost and building sites are quickly made accessible. The use of a natural product avoids primary pollution. Additional modifications extend the product range to include qualities that produce less dust – which is particularly important for reconstruction projects in built-up areas.
For road surfacing, refined qualities of Oxycal® and Fillcal® are used to slow down the ageing of asphalt. Through the chemical reaction with bitumen, the asphalt surface becomes more resistant to higher temperatures and is protected against embrittlement cracks and cracking due to moisture absorption.
Special industrial applications have led to the introduction of blended products with a chemically refined calcium oxide base. One example is the use of Fillcal® products for asphalt surfacing.
