Guide: How to Choose the Right Landscape Supplies for Your Project

TMH Industries Landscape Supply – Calgary’s trusted source for gravel, decorative rock, soil, mulch, and more.

Step 1: Identify the Type of Landscape Project

Understanding your project helps you choose the correct material:

• Garden beds – Use screened topsoil or garden mix soil
  
  
• Driveways or pathways – Use 25mm road crush gravel
  
  
• Playgrounds or under pavers – Use 5mm washed sand under pavers, and 10mm washed round rock for playground
  
  
• Dry riverbeds or drainage – Use 40mm washed round rock or Class 1M limestone
  
  
• Weed control or ground cover – Use decorative rock with landscape fabric or wood mulch
  

Step 2: Calculate How Much Material You Need

Use this basic formula to estimate your required cubic yards:

Length (ft) × Width (ft) × Depth (inches) ÷ 324 = Cubic Yards

Example: A 10ft x 10ft area at 6 inches deep
= 10 × 10 × 6 ÷ 324 = 1.85 cubic yards

Step 3: Choose the Right Landscaping Material

Decorative Rock
Great for enhancing curb appeal. Popular choices include 20mm Limestone Rock, 40mm Montana Rainbow Rock, 40mm Crystal White Rock, and 40mm Rundle Rock.

Crushed Gravel
Perfect for road bases, patios, and hardscape foundations. Use 25mm Road Crush for stability.

Soil and Garden Mix
Ideal for planters, gardens, and new lawns. Garden mix promotes healthy root development.

Sand
Used under pavers, in play areas, and for levelling. Choose 5mm washed sand for clean, consistent coverage.

Mulch
Conserves moisture, reduces weeds, and improves visual appeal. Great for flower beds and tree rings.

Step 4: Select a Format That Fits Your Job

Final Tip

If your estimate is close, round up to the nearest ½ yard or full yard to ensure full coverage. Grading and settling often require a little extra material during installation. If unsure, contact us for guidance.
