Construction Sand

Construction Sand from Pakistan

Construction sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is the most widely consumed sand type, with applications spanning building construction, road paving, and all forms of concrete. Pakistan’s diverse geology and extensive river systems yield construction sand deposits with excellent grain shape, size distribution, and freedom from deleterious substances, making it a top choice for builders.
