FAQs
Use Gravel Coverage for landscaping gravel, decorative stone, drainage gravel, and driveway materials. Use Sand Coverage for paving, screeds, plastering, rendering, play sand, and top dressing. Use Aggregate Coverage for GSB, WMM, MOT Type 1, crushed stone, road sub-base, drainage aggregate, and brass-based construction estimates.
Each calculator can find coverage area from an available quantity and depth, calculate the quantity required for a target area and depth, or determine the depth achievable from a known quantity and area.
