Product information
Consistent quality control is maintained by three laboratories throughout the country, carrying out regular quality testing. We have our own X-Ray Fluorescence (XRF) machine to determine the calcium carbonate content of asphalt fillers.
You can use our limestone filler in asphalt mixtures for:
- road surfaces (A and B roads, motorways)
- construction of airfields and runways (commercial and armed forces airports)
- mastic asphalts in a variety of applications
Another use of Limestone filler, not connected to the construction industry, is its use as a calcium-based agricultural fertiliser.
