Frequently Asked Questions

How can I make delivery safer?
When you order, please let us know about any hazards our drivers might encounter on the way to your jobsite. Hazards include low power lines, soft dirt, septic tanks, narrow and curvy driveways, entrances on busy roads, bushy trees, low limbs, and other obstacles we should know about.

Do you finish concrete? Can you lay down rock? Do you pave driveways?
River Bend is not a contractor. We supply concrete, asphalt, and rock, but we do not install them.

Do you have concrete pump trucks?
We do not provide concrete pumping equipment.

How do I order concrete? How do I order rock?
Call our ready mix concrete dispatcher at 503-363-9284 to order concrete. Call our rock dispatcher at 503-363-9237 to order rock.

Should I call in advance to order material?
Yes. For concrete, please order 4 to 5 days ahead. For rock, give us 2 to 3 days.

Where are you located?
Our physical address is 4105 Lancaster Drive SE, Salem, Oregon. Click here to see our map location.

I don’t have an account. How should I pay?
Customers without an account must pay COD. River Bend accepts MasterCard and Visa. COD customers can provide credit card information at the time they order, or pay by check or cash at the time of delivery. If you want to pay by cash or check, please pay the driver. Checks must have a valid address and phone number. The driver must receive payment before the driver is allowed to unload any material. Click here for a credit application.

What are your minimum orders?
Our minimum rock order for delivery is 10 tons. One cubic yard is the minimum order for concrete, but extra fees are added to concrete orders of less than 6 yards. Please call for more information, or check our price list by clicking here.

Why do you add a fee to small orders?
When we send a truck and driver to your location, our equipment and payroll costs are the same whether we have two yards in the drum or 10 yards. However, we charge by the yard. The amount we make on 10 yards covers our costs, but the amount we make on two yards does not. Therefore, we have to add a fee to small orders.

What is truck time?
Truck time is the fee we charge when a customer exceeds the time limit for our ready mix trucks. Each customer gets 6 minutes per yard to offload the truck, or one hour for a full load. We allow at least 30 minutes for everyone, no matter how small the order. We do this for two reasons. First is scheduling: To be on time for the next customer, we have to make sure the current customer is efficient with our truck. Second, we need to cover our costs when a customer hangs on to our truck for a long time, because it reduces the number of deliveries the truck will make that day. We charge $1.25 per minute when customers exceed the allowable time limit.

Why does concrete crack?
Part of the reason is that concrete has a high compressive strength (it can hold up a heavy load) but a relatively low tensile strength (the force that keeps it from pulling apart). Concrete with a compressive strength of 4,000 psi has a flexural (similar to tensile) strength of about 650 psi. There are many direct causes for cracking, but the most common is shrinkage. When concrete dries out, it shrinks and tries to move. When something prevents that movement – like a post, or a corner, or just a section of slab that’s too heavy to move – the concrete will crack.

How much material does a truck hold?
A full load of concrete is 10 yards. A full load of rock is about 15 tons in a solo dump truck and 32 tons in a truck with a trailer.

How much does a cubic yard of rock weigh?
There is no particularly accurate conversion, since the weight of a given unit of rock will change easily with changes in moisture and compaction. However, our general rule of thumb for ‘loose’ base rock is 1.35 tons per cubic yard.

What is fly ash? Why is it used?
Fly ash is the collected and graded particulate, or ash, given off by burning coal at coal-fired power plants. This material often ends up in a landfill, but at River Bend we like to recycle it. Fly ash can be used to replace a percentage of the cement that goes into concrete. Since fly ash particles are smaller and rounder than cement particles they make concrete denser, less permeable to water, more resistant to chemicals and salts in the soil, slicker to pump, and smoother to finish.
