Adding rock to your landscape gives your design a natural, authentic look that thrives in Arizona's climate. With zero water requirements and virtually no maintenance, rock-based landscapes are one of the smartest long-term investments a Gilbert homeowner can make.

At Scape Tech, we provide a wide range of landscaping materials including flagstone, decorative rock, boulders, rip rap, gravel, soil, and sand. Here's a breakdown of the main categories and how to use each one effectively.

Gravel

Gravel is perfect for filling around and accenting plants, trees, grass areas, and walls. It requires no water, is ideal for dry climates and water-restricted areas, and significantly reduces weed growth when properly installed over weed barrier fabric.

Size options: Sized (0\xe2\x80\x9310% crusher fines), Screened (10\xe2\x80\x9340% crusher fines), Minus (80\xe2\x80\x9390% crusher fines)

Color options: Gold Granites, Tan Granites, Beige Granites, Brown Granites, Pink/Red Granites

River Rock

River rock is used for decoration around landscape beds, fountain features, and as a complementary shape and texture alongside other materials. Its smooth, rounded form adds a softer, natural feel compared to crushed gravel.

Available sizes: 3/8" Crushed Pea Gravel, 1/2" Crushed River Rock, 3/4\xe2\x80\x931.5" Natural River Rock, 1" Crushed, 1\xe2\x80\x933" Natural, 3\xe2\x80\x938" Natural, 8"+ Natural

Boulders

Surface Select Boulders are naturally occurring weathered granite boulders that vary in color from light to dark brown. They add dramatic scale and authentic Southwestern character to any landscape \xe2\x80\x94 and once placed, require absolutely zero maintenance.

Size range: Approximately 1'x1' up to 5'x5' and larger. Every cubic foot weighs approximately 100 pounds. Rip Rap Rock is also available.

🪨 Material Tip

For the most natural look, mix two or three different rock types and sizes in the same design. A base of decomposed granite with larger river rock accents and one or two statement boulders creates depth and visual interest that a single material never achieves.

Rock-based landscapes are the ultimate Arizona investment: stunning to look at, zero water required, zero maintenance, and they only improve with age.
