Credit Application


No matter what we do, safety is our number one priority.  From our four concrete plants, to our trucks on the road, and on the job site we work as a team to keep everyone safe.

Since implementing our “Safe Man Hours” program in January 2007, we have twice achieved our goal of zero “lost time accidents” for a 12-month period.  We accomplished this first from February 2007 through May 2008, and once again starting in August 2008 – Present.

Everyone at Lynchburg Ready Mix understands how important safety is, and the individual and team efforts have led us to be recognized by the VRMCA as a leader in safety.


Safety Documents


It all starts with a phone call.  Our dispatch will work with you to place your order for the proper concrete mix and set up a time, date, and location for your pour. Delivery schedules fill up quickly and so it is recommended that you place your order 24 hours in advance.  When you call to place your order, please provide the dispatcher with as much information as possible so that you are ensured to receive the best product at the correct time.  For further information, please refer to CIP #31.

When placing your order, the dispatcher will want to know:

Name – Account name, or contractor/home owner name of C.O.D. orders.

Date and Time

Address/Directions – The job-site address and/or lot#

Telephone Number – So dispatch can contact you should any questions arise about your delivery.

Mix and Slump – Dispatch can help you determine the proper mix and slump based on the type of project you are doing.

Amount of Concrete – Dispatchers are equipped and ready to help you figure your ready mix needs when you supply them with your dimensions. Always order 10% extra to compensate for an uneven sub-base, spillage, spreading of forms, and settling of sub-grade. Running short can be costly in both time and money. Round orders up to the nearest ¼ yard.

Firm or Will Call Order – A firm order means that your concrete will be delivered at the agreed upon time unless you call to cancel. A will-call order means that you are expecting to pour and dispatch is expecting to deliver the concrete to you at the next available time when you call to confirm your order.

Truck Spacing – If your order requires more than one truck, you will be asked how long you need to empty each truck.

Extra Products – Extra products include fibers, accelerators, hot or chilled water, and other admixtures that change the properties of the mix.  View the PRODUCT ENHANCEMENTS section for a detailed description of the extra products offered.
