Hardscaping Made Easy: Unilock DURA-HOLD II® for Your Outdoor Space

Why Hardscaping Matters

Imagine your backyard as a blank canvas. Softscaping is the paint—flowers, shrubs, and trees. Hardscaping, on the other hand, is the frame that holds everything together. Think patios, pathways, and retaining walls. Without good hardscaping, your outdoor space can feel unfinished or even unstable. That’s where Unilock’s DURA-HOLD II® comes in—an ultra-durable, easy-to-install retaining wall system perfect for homeowners looking to enhance their backyard with both function and beauty.

Meet DURA-HOLD II®

DURA-HOLD II® is the practical, cost-effective version of the classic DURA-HOLD® retaining wall system. Designed for stability and ease, it maintains the same sturdy look but at half the depth. If you need a strong, long-lasting retaining wall without excessive bulk, this product is a game-changer.

  • Driveway Retaining Walls: Prevent soil erosion while adding curb appeal.

Installation Guide

Step-by-Step Process

  1. Plan Your Layout: Mark the area where your retaining wall will go.
  2. Excavate the Base: Dig at least 6-8 inches deep to create a stable foundation.
  3. Lay the Base Material: Use compacted gravel or open-graded stone for stability.
  4. Set the First Course: Place DURA-HOLD II® blocks on the leveled surface.
  5. Stack and Secure: Use the tongue-and-groove system for a secure fit.
  6. Backfill and Compact: Add gravel behind the wall for drainage.
  7. Cap with Coping: Attach the coping pieces to complete the look.

DIY vs. Hiring a Pro

  • DIYers: You’ll need an excavator or special lifting clamps for handling these large blocks.
  • Professionals: If you’re dealing with slopes, drainage issues, or high walls, hiring a contractor is best.

Why Choose DURA-HOLD II®?

  • Durability: Made to withstand weather, erosion, and pressure.
  • Aesthetics: Provides a polished, professional finish.
  • Efficiency: Covers more space per unit, reducing installation time.
  • Cost-Effective: Uses less material than full-depth DURA-HOLD® while maintaining the same appearance.

Shopping Tips

  • Check Material Quality: Look for uniformity and strength in each block.
  • Match to Your Space: Ensure the size and color work with your outdoor design.
  • Avoid Common Mistakes: Don’t skimp on base preparation or proper drainage.
