What about delivery charges?
Delivery is available valley-wide. We offer FREE DELIVERY within our home zone for orders of  ten (10) tons and up.  Outside the free delivery zone (or for smaller loads) a nominal delivery charge can apply.  Please call in advance for scheduling, availability and pricing. The weight of different products (split loads) cannot be added together in considering the delivery charges. Check out the delivery section of our Pricing page for more details.
What is a split order?
Two different products. Also known as a 'split load.'  If you have two different products being delivered to you on the same truck, the delivery charge is calculated for one product of the 'split order' plus a $15 charge for the second product of the 'split order.'

What are 'fines?'
'Fines' is the term used to describe the crushed rock and very small miscellaneous dirt and debris found in any gravel or decorative rock.
ALL GRAVEL CONTAINS FINES.

What do the terms
sized,  screened, and
minus mean?
These terms refer to the size of the decorative rock, as defined by the largest piece which would fit through a screen of a pre-determined size. The terms also help to denote the approximate amount of fines present in a product. For instance, the term 'sized' can signify up to 15% fines in the product, whereas 'screened' can mean 10% to 20% fines in the product, and when we visualize a product described by the term 'minus'  we know it will have 60% to 70% fines.

What is Rip Rap?
Think of rip rap as large stones with angular shapes, larger than gravel but smaller than boulders. Rip rap can  vary in size from about the size of a softball to as large as approximately 10"  to 12" in diameter. The average is usually from about 3" to 8" in size. One ton of rip rap will usually cover an area of 35 to 40 linear feet, spread 3' wide.

How can I match my existing granite color?
Due to the nature of mined substances such as granite, colors and consistencies of granites may vary. Color change will occur with aging, and therefore matching your existing granite may not be possible. Bring a sample with you to our yard and our experts will find the closest match for you.

How do I calculate the square footage of my yard?
Easy. Just measure the length and width of the yard, then multiply the two figures.  Check out our TIPS AND TRICKS page for more hints and an easy-to-use chart to help you estimate how much rock you'll need to cover your yard.

What is pea gravel?
Otherwise known as 3/8" and 1/4" natural, this is crushed river rock. River rock described by simply the term 'natural' will mean it is natural river stone, not crushed.

What's the difference between a surface boulder and a regular boulder?
You'll hear the term 'custom boulder' and also the term 'surface bulder.'  A surface boulder is just that, it is picked up off the surface of the earth, whereas a custom boulder is quarried from the earth.

Tell me more about flagstone!
There are five basic categories of flagstone: Regular select, thin select, patio select, coping, and slabs.  
Regular select is a grade of flagstone characterized by pieces of stone approximately 2' by 3' in surface area. Thickeness is between 1" to 1 3/4". It is generally used in outdoor patio applications.
Thin select is a grade characterized by pieces of stone approximately 2' by 3' in surface area. Thickness is 1" or less, but not usually less than 1/2 inch. It is generally used in indoor flooring applications, but may also be used in the same applications as regular select with proper installation techniques.
Patio select is characterized by pieces of stone that are less than four square feet in surface area. Thickness is between 1 and 2 inches. The pieces are generally the leftovers from making regular select.
Coping is a category of flagstone pieces used as edging, generally used as edging around pools.  Coping usually ranges in thickness from 1 3/4" to 4".
Slabs are larger pieces of flagstone used for signs, tables, and other custom applications.
Now let's go over color shades.  Remeber that flagstone is a natural stone and therefore colors may vary slightly, but as a general rule you can use this as a guideline:
Rosa is generally a dark purple-pink, with some golden tones. Also known as dark pink.
Light Rose is usually a mixture of pinks and tans. Also called Light Pink.
Peach will have a mixture of pinks and golden tones in it, but not as dark as Rosa.
Buff is generally a mixture of tan and gold tones. It is also called Buckskin or Apache.
Classic Oak normally has a white to beige-white tone, with some hints of pale green.
Sedona Red is generally a dark red to red-orange. This is one of the softer flagstones.
