Tips for ordering
When finding the amount of concrete you need, Measurements aren't always exact, so we highly recommend our customers to order a little bit extra. A good rule of thumb is to take your calculation and add anywhere from 5-10% of the total to account for waste, spillage, over excavation, settlement, loss of entrained air, and other changes in volume. Remember, you can order concrete in half yard increments.
Slump is a measurement of the consistency of the concrete. A 4 inch slump is ideal. Keep in mind adding one gallon of water per cubic yard can decrease the compressive strength of concrete by 150-200 psi, waste cement, and increase shrinkage by 10%. This can be problematic for those who pour in freeze/thaw conditions.
Strength is most commonly measured by the designed compressive strength in pounds per square inch (PSI) of a hardened cylinder of concrete. Any slab exposed to freeze thaw conditions should be a minimum of 4000psi. Estate concrete offers 3500, 4000, 4500, and 5000 psi concrete.
You will need to provide a contained area for trucks to washout. This area would not allow fluids to seep into surrounding areas. We have portable washout boxes available for a fee. inquire with dispatcher.

Air entrained concrete
Air-entraining admixtures facilitate the development of a system of microscopic air bubbles within concrete during mixing. They increase the freeze-thaw durability of concrete. We recommend you order air entrained concrete when pouring in freezing/thaw conditions, or for concrete exposed to weather.
Non-Air entrained concrete
Air entrained admixtures should not be used on floors when attempting to achieve a dense and smooth surface.
Non air entrained concrete is ideal for interior work, and for hard troweled finishes.
