A concrete truck’s maximum load capacity is 10 cubic yards when completely loaded. Depending on the thickness of the concrete slab, ten cubic yards of concrete can cover an area between 270 and 810 square feet.
Experienced concrete contractors understand the significance of obtaining the exact amount of concrete required to accomplish a project and take care to order the precise amount. Due to the imperfect nature of construction sites, contractors often order 10 to 15 percent more concrete than is required to accommodate for spillage, uneven terrain, and form movement. This frequently results in excess concrete following a pour, although having too much is preferable to having too little. A shortage loses both time and money because workers are idle while awaiting the return of the concrete truck, and the contractor incurs additional expenses.
When a contractor orders less than a complete load of concrete, concrete suppliers will add a surcharge to the entire invoice amount. Every time a concrete truck delivers a load, fixed expenses are incurred. When the truck is fully loaded, these expenses are met. These costs are not covered when the truck is carrying less than a full load, so the additional price is paid to cover the total cost of delivery.
