UNILOCK DURA-HOLD®

Transform Your Outdoor Space with Unilock DURA-HOLD® Retaining Walls

Why Hardscaping Matters

If you’re looking to create an outdoor space that’s both beautiful and functional, hardscaping is key. Unlike plants and greenery (which need constant care), hardscape elements like patios, walkways, and retaining walls add structure and durability to your yard. They help define spaces, prevent erosion, and enhance curb appeal—all while requiring minimal maintenance. One standout product that makes hardscaping easy and effective is Unilock DURA-HOLD®.

Meet DURA-HOLD®: A Game-Changer for Retaining Walls

If you’ve ever seen a crumbling retaining wall or worried about soil erosion in your backyard, you know how important a solid wall can be. That’s where Unilock DURA-HOLD® comes in. It’s a high-strength, large-scale retaining wall system designed to hold back soil while looking great. Think of it like Lego for grown-ups—each block is engineered to interlock securely and form a strong, durable barrier.

Where Can You Use DURA-HOLD®?

This product is perfect for homeowners who need to tackle significant elevation changes or create tiered landscapes. Here are some common uses:

  • Terracing a sloped backyard – If your yard slopes, this system helps create leveled sections, perfect for gardens or patios.
  • Building strong garden beds – Elevate flower beds or vegetable gardens with sturdy, well-defined edges.
  • Preventing erosion near driveways or patios – Keep soil from washing away during heavy rain.
  • Creating a seating wall around a fire pit – Dual-purpose hardscaping for function and style.
  • Supporting pool decks or outdoor kitchens – Adds strength while enhancing aesthetics.

Installation Guide: DIY or Pro?

Installing a DURA-HOLD® wall is not your average weekend project. Since each block weighs over 1,600 lbs, this is a job that typically requires heavy equipment and professional handling. However, if you’re a seasoned DIYer with access to a skid steer, here’s a basic breakdown:

  1. Prepare the Base:
    • Excavate a trench deep enough to hold 6-8 inches of compacted gravel.
    • Compact the base layer until it’s firm and level.
  2. Lay the First Course:
    • Place the first row of blocks on the base, ensuring they are level.
    • Use a string line to maintain alignment.
  3. Add Reinforcement (If Needed):
    • For walls taller than 6 feet, use geogrid reinforcement.
    • Insert geogrid layers every few rows for added strength.
  4. Stack the Blocks:
    • Interlock each layer using the built-in tongue and groove connection.
    • Check for level as you go.
  5. Cap It Off:
    • Use DURA-HOLD® coping for a finished top layer.
    • No adhesive is needed; the coping locks in place.

For walls over 6 feet tall, professional engineering is required.

Why DURA-HOLD® Stands Out

  • Incredible Durability – Built to last, even under extreme weather conditions.
  • Time-Saving Installation – Each block covers 6 face feet, reducing install time.
  • Strong, Secure Connection – Tongue and groove design ensures stability.
  • Low Maintenance – No shifting, settling, or costly repairs.

Best Practices When Shopping

  • Quality Matters – Look for high-density concrete to ensure longevity.
  • Consider Your Space – Measure carefully to determine how many blocks you need.
  • Don’t Cut Corners – Skimping on base prep or reinforcement can lead to failure.
