FAQs

Do you guarantee your products?

Since natural stone is a product of nature, we include the following disclaimer on all sales: All stone is a product of nature and cannot be guaranteed for color, shape, uniformity, or tendency to fracture. The variation of color, shape, and texture is inherent to and an integral part of the characteristics of natural stone. Installers should be aware of and discard any irregular or abnormal piece that might be present before installation.

How much Decorative Rock do I need?

Our general rule of thumb is one yard of rock will cover 100 square feet at a depth of approximately 2 inches. Use our calculators to get a quick estimate of the amount of material you’ll need for your project.

What sizes of Decorative Rock are there?

In general, the most common dimensions of Decorative Rock are 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch, or 1 inch up to 1 ¼ inch. Sizes vary depending on the mine and equipment used to crush it.

What is the best depth for Decorative Rock?

We typically recommend a depth of 2 inches for most Decorative Rock installations. Recommended depths vary based on the intended use.

What is the difference between screened, minus, and washed rock?

The classes of rock are based around the number of fines – dirt which goes through the screening process and ends up in the final product – they contain. The three most common classes are minus, screened, and washed. ‘Minus’ rock can contain up to 80% fines, making it look more like a pile of dirt with some rocks than the other way around. ‘Screened’ rock typically contains between 20% and 40% fines. The cleanest, or most ‘pure,’ rock is ‘washed’ rock.

What does the “minus” mean when you see a product size like 3/8″-?

When you see a product with a minus (3/8″-), it means that the rock is from 3/8″ down to sand size. If you want nothing but the crushed rock with no smaller particles, request the screened 3/8″ rock.

What if the rock I receive is not the same color as the rock I ordered?

Rock is a natural product and will therefore always have color variations. It is virtually impossible to guarantee the color of a given kind of rock unless the customer makes their selection at the quarry itself. Ordinarily, the color difference between a sample and the rock that is delivered should only vary in color by a shade or two.

How should I install Decorative Rock once I have it?

There are two ways that we recommend the installation of your decorative rock: hire a qualified installation contractor, or do it yourself. If you do it yourself, make sure you’re prepared with the right tools on hand. For small quantities, you’ll need a sturdy wheelbarrow, a round nose shovel, and a flat nose shovel, good leather work gloves, and sturdy shoes or boots. For medium to large jobs, we recommend renting a small skid loader, available from most rental yards, and some extra labor.

How do I keep weeds from growing in my rock?

There are several weed-prevention solutions available for most installations. We recommend either of the following weed-prevention materials: Landscape fabric – A tough, fibrous black fabric installed as a base for the rock on the prepared ground. It is less sun-sensitive and easier to install. Being porous, it breathes and allows water to flow through it. Its dense weave keeps weeds from growing through. Pre- or post-emergence chemical or environmentally safe sprays. A pre-emergence solution is sprayed on bare ground, deterring seeds from germinating. It does need to be re-applied periodically depending on rain and drainage. Post-emergence sprays or solutions work as or after weeds appear in the landscape. This method works as long as you stay on top of it and kill the weeds or grass early and regularly.

You offer a variety of sands. What is the difference between concrete sand, plaster sand, fill and infill sand?

Concrete Sand is a coarse sand with larger particles. This type of sand is typically used in concrete but can also be used as pipe sand or as a base layer and leveling medium for above ground pools, and patios or walkways made of concrete paving stones. Plaster Sand is finer grade sand with smaller particles. It’s often mixed with water and cement to make mortar for laying bricks/blocks. It can be used in cement, particularly for projects like swimming pools and concrete paving stones where the finer grain gives a more finished appearance. Its finer texture also makes it an acceptable replacement for beach sand in applications like sand volleyball courts. Fill Sand is non-processed sand. Product size ranges from occasional 2″ rock down to 15% silt and clay. This product is excellent for fill under slabs, fill behind retaining walls, and trench fill applications that do not require any particular particle size gradation. Infill Sand is used in artificial grass as a stable base to hold the blades upright and to retain a springy feeling. Typically colored green, it is spread between one-eighth and one-quarter inch deep within the grass blades and allows the artificial turf to remain functional and aesthetically pleasing.
