Introduction

Receiving your first Ready Mix Concrete delivery can be overwhelming, but understanding the delivery process is crucial for a successful project. This guide will walk you through the essential aspects of Ready Mix Concrete delivery, helping you navigate the process with confidence.

Ordering the Right Amount

One of the most critical aspects of ordering Ready Mix Concrete is ensuring you order the right amount. It’s recommended to include a margin of error when calculating your needs. Seasoned contractors might factor in a 5-10% margin, while first-timers should consider a 10-15% buffer. Accurate dimensions are key, and it’s highly recommended to work with a contractor to ensure proper calculations.

Preparing for Delivery

Being fully prepared before the delivery is essential. Remember, once the concrete is in the truck, there’s no turning back. The concrete will start to set, so avoid pushing tight schedules. Ensure your site is ready, and all necessary preparations are complete before the truck arrives.

Unloading the Truck and Site Access

Ready Mix companies have a “Beyond The Curb Policy” which requires the property owner or contractor to sign a liability release for the truck to drive onto the property. If the delivery site is on a busy road, inform the delivery company in advance so the driver can be prepared to pull straight onto the driveway. Keep in mind that concrete delivery can be messy, with minor spills being common. Also, these trucks loaded can weigh more than 60,000 lbs!

Types of Ready Mix Delivery Trucks

There are several types of Ready Mix delivery trucks:

1. Rear Discharge Trucks: The most common type, with the concrete discharged from the back of the truck. The driver controls the flow and speed of the drum and chutes from the rear of the vehicle. Typical length of 30-36’.
2. Front Discharge Trucks: Concrete is discharged from a chute extending over the cab. The driver controls the chute and discharge from inside the cab, allowing for better visibility. Typical length of 36-40’.
3. Volumetric Mixers: These trucks carry unmixed materials and mix the concrete on-site. They produce less waste and have a lower carbon footprint compared to traditional drum trucks. Typical length of 30-40’. This truck type is the one we use.

Access Considerations

Delivery trucks are large, ranging from 30 to 40 feet in length and 11.5 to 13.5 feet in height. Ensure there is adequate space for the truck to maneuver and unload safely. If access to the site is challenging, you should consider using a concrete pump; although these do add cost up front they will save a lot of time in physical labor and reduce everyones time onsite. Taking the truck off a paved surface can not be counted on and the final decision is up to the delivery driver, Do Not Count on off road operations (get a concrete pump).  If the driver agrees to go off a paved surface a liability waiver will be required. The property owner will be responsible for any damage to the property, equipment, infrastructure, and any necessary towing. Be aware of underground utilities, septic systems, or other infrastructure that could be impacted by the weight of the truck; these trucks are extremely heavy.

Post-Job Requirements (Washout)

This is the most common step that is forgotten about. After the concrete has been delivered, the delivery truck must be cleaned on-site. This process is known as a “washout.” As concrete can quickly harden, it’s crucial to clean the truck’s chute, drum, auger, and any other equipment that came into contact with the concrete.

The delivery driver will need a designated area to perform the washout, which should be prepared before the truck arrives. This area should be large enough to accommodate the washout materials, which typically include a mixture of concrete residue, sand, aggregate, and water.

Common washout methods include:

• Wheelbarrow: The most common method is to use one or two wheelbarrows to collect the washout materials. The driver will rinse the chute and drum, directing the washout into the wheelbarrows.
• Washout Pit: A washout pit is a pre-dug hole lined with plastic sheeting to prevent the washout materials from seeping into the ground. The driver will direct the washout into the pit, which can later be filled in and disposed of properly.
• Washout Bag: If a washout area cannot be provided, a washout bag can be used. These bags are designed to contain the washout materials and can be left on-site for later disposal.

It’s important to note that volumetric trucks require a larger amount of water for cleaning due to the extended mixing process inside the truck.

After the washout is complete, the materials should be left to settle and harden. Once hardened, the washout can be disposed of in accordance with local regulations. It’s the responsibility of the property owner or contractor to ensure proper disposal of the washout materials.

By providing a suitable washout area and understanding the washout process, you can help ensure a smooth and environmentally responsible conclusion to your Ready Mix Concrete delivery.

Scheduling the Delivery

Schedule the delivery well in advance and communicate any changes or delays to the supplier promptly. This helps ensure a smooth delivery process and avoids any last-minute issues.

Weather Considerations

Weather conditions can significantly impact the delivery and pouring of concrete. Be aware of the guidelines for pouring in various weather conditions such as extreme heat cold or rain. Discuss any concerns with your supplier to ensure the best possible outcome.

Safety Precautions

Safety is paramount during a concrete delivery. Ensure that all individuals on the job site wear appropriate personal protective equipment (PPE) and maintain a safe distance from the truck during unloading. Follow the delivery crew’s instructions and any additional safety guidelines provided by your contractor or supplier.

Glossary

• Slump: A measure of concrete’s consistency and workability.
• Curing: The process of maintaining suitable moisture and temperature conditions to allow the concrete to reach its desired strength and durability.
• Washout: The process of cleaning the concrete truck’s chute and drum after delivery to prevent residual concrete from hardening inside the equipment.

Conclusion

By understanding the key aspects of Ready Mix Concrete delivery, you’ll be well-prepared for your first delivery. Remember to order the right amount, prepare your site, consider access and weather conditions, prioritize safety, and communicate effectively with your supplier. With proper planning and attention to detail, your concrete delivery and project will be a success.
