We use ¾ minus″ rock. Due to the gradation of the rock, some of the stones are as small as 1/4″.
We do not carry wheelbarrows on the truck!
It depends on several different factors, but normally you can walk on it CAREFULLY (No twisting!) in about 12 hours. After 48 hours you can remove the forms, but it’s better to leave them on for a whole week if possible. In 2 weeks you can park a car on your concrete. After 28 days, the concrete reaches its full strength.
We recommend at least 4 inches on driveways, patios, sidewalks, and most slabs that we pour.
It depends on the application, but usually for driveways or other heavy-use areas, yes, using rebar and/or mesh helps to reduce cracking.
We highly recommend a sturdy gravel base. A base that is compacted and 2-3 inches deep is best.
You should have at least a bull float edger and hand trowel. You can buy these tools at any of the building supply stores, or you can rent them at most rental shops.
One cubic yard will fill about 10-12 pier blocks.
No, we are primarily a supply and delivery company, but give us a call and we can recommend someone.
Air entrapment means the induction of very small air bubbles into fresh concrete. When the concrete hardens, the air bubbles form small voids, and these voids give concrete additional durability in freezing or thawing conditions.
Again, here are some guidelines:
2500 PSI 4% – 5%
3500 PSI 4% – 5.5%
4000 PSI 5% – 6%
Here are some approximate values for underground tanks:
1,000 gallons 5-6 yards
675 gallons 3 – 4 yards
500 gallons 2.5 – 3 yards
To best protect your newly poured concrete, keeping it covered with hay or straw for two weeks should help.
It takes about 10-12 wheelbarrow full of concrete to make up a cubic yard.
One yard weights approximately 3,800 lbs. (nearly two tons).
It takes one (1) cubic yard of concrete to fill eighty (80) 8-inch blocks. One cubic yard will also fill fifty (50) 12-inch blocks.
Your pour can be five (5) feet high without a chute. With all chutes on, your pour can be 2 1/2 feet high. *Volumetric Truck Only
