Working with Rock Hard as homeowners
Building your first home? Start with the calculator.
The Rock Hard Cement Calculator turns slab area, wall length, plaster area and mortar volume into a bag count you can trust. It uses standard Jamaican construction ratios — 1:2:4 for slab and foundation concrete, 1:4 for block mortar and plaster — and rounds up so you don’t run short at the pour. When the estimate looks right, one tap turns it into a quote request.
Delivery straight to your site
Every parish has a delivery fee that’s quoted upfront — no surprises at dispatch. Kingston, St. Andrew and St. Catherine deliveries can be same-day if the order is placed before 10:00 AM. Rural parishes and the north coast are typically 24–72 hours. You’ll get live status updates and a digital delivery slip signed on drop.
Real people, when you need them
You can call (876) 518-9190 or WhatsApp us if the calculator doesn’t cover your build. Send a photo of the drawings, tell us the parish, and a Rock Hard advisor will help you size the order and pick the right format.
