Washing separates the sand from the stone and removes any undesirable super-fine sands and silts. Washing also classifies the sands into different gradations. Our washing plant in Limehouse (the only of it's kind in Halton Region) produces 3 types of washed sand and 4 sizes of washed round or crushed stone
