Enhancing your property with interlocking pavers can significantly boost curb appeal and functionality. Whether you're looking to create a new patio, pathway, or driveway, understanding the installation process ensures a successful outcome. This guide provides step-by-step instructions for DIY enthusiasts and highlights Treff Landscaping in London, ON as your go-to professionals for expert installation.

Understanding Interlocking Pavers

Difference Between Pavers and Interlocking

  • Pavers: Generally refer to any type of flat, brick-like stone used for paving.
  • Interlocking Pavers: Specifically designed with joints that interlock tightly together when laid in a specific pattern. This design prevents movement and enhances durability.

Best Interlocking Pavers for Extreme Conditions

  • Climate Considerations: Choose interlocking pavers designed to withstand extreme cold and heat. Options like concrete or natural stone pavers with high compressive strength and low water absorption are ideal for durability in varied climates.
  • Companies: Consider reputable manufacturers like Unilock or Permacon for high-quality interlocking pavers.

Planning Your Project

Step 1: Design and Layout

  • Measure and sketch the area where you intend to install interlocking pavers.
  • Consider the desired pattern, such as herringbone or basket weave, to complement your property's style.

Step 2: Materials and Tools

  • Materials: Interlocking pavers, gravel base material, coarse sand, edge restraints (like plastic or metal paver edging), and HPB (High Performance Bedding).
  • Tools: Shovel, wheelbarrow, plate compactor (available for rent), level, rubber mallet, and broom.

DIY Installation Steps

Step 1: Excavation and Base Preparation

  • Excavate the area to a depth that accommodates the pavers plus base materials (typically 6-8 inches).
  • Add a base layer of gravel and compact it thoroughly with a plate compactor to create a stable foundation.

Step 2: Setting the Base and Sand Bed

  • Spread a layer of coarse sand over the compacted gravel base. Use a screed board or level to ensure an even thickness (usually 1 inch).
  • Compact the sand with a plate compactor to create a smooth, level surface for laying pavers.

Step 3: Laying Interlocking Pavers

  • Start laying pavers from one corner of the area, following your chosen pattern. Place each paver tightly against the next, using a rubber mallet to tap them into place if needed.
  • Check periodically with a level to maintain a flat surface. Cut pavers as necessary to fit edges or curves using a saw with a diamond blade.

Step 4: Sand and Joint Compounds

  • Once all pavers are laid, spread fine sand over the surface and sweep it into the joints. Compact the pavers again to ensure sand settles evenly.

Joint Compounds: Polymeric Sand vs. Stone Dust

Polymeric Sand

  • What it is: A mixture of fine sand and special additives that form a binding agent when activated with water.
  • Why use it: Polymeric sand hardens in the joints to prevent weed growth, deter ants, and resist erosion. It's especially useful for areas with heavy foot traffic or exposure to the elements.

Stone Dust

  • What it is: A byproduct of crushing stones, consisting of fine particles.
  • Why use it: Stone dust is cost-effective and easy to apply, providing a firm, smooth base that locks the pavers in place. It allows for some flexibility and can be useful in installations where slight movement is expected.

Importance of Using HPB (High Performance Bedding)

What is HPB?

HPB, or High Performance Bedding, is a type of angular crushed stone that is used as a base material for interlocking paver projects. It is known for its excellent drainage properties and stability, making it an ideal choice for creating a solid foundation for driveways, walkways, and patios.

Benefits of Using HPB

  1. Superior Drainage
    • Key Feature: HPB consists of clean, angular stones that allow water to flow freely through the gaps, preventing water accumulation and reducing the risk of frost heave or erosion.
    • Benefit: Improved drainage helps maintain the integrity of the paver installation, especially in areas with heavy rainfall or freeze-thaw cycles.
  2. Stability and Load Distribution
    • Key Feature: The angular nature of HPB stones ensures they lock together tightly when compacted, creating a stable and supportive base.
    • Benefit: This stability distributes loads evenly, reducing the risk of pavers shifting or settling over time, even under heavy traffic.
  3. Ease of Installation
    • Key Feature: HPB does not require compaction, unlike traditional gravel or sand bases.
    • Benefit: This simplifies the installation process and saves time, as the material can be laid directly and uniformly without the need for heavy compaction equipment.
  4. Low Maintenance
    • Key Feature: Because HPB provides excellent drainage and stability, it requires minimal maintenance over time.
    • Benefit: Homeowners can enjoy a long-lasting, durable surface with fewer concerns about water-related issues or settling.

Treff Landscaping’s Approach with HPB

At Treff Landscaping, we prioritize the use of HPB for our interlocking projects due to its numerous advantages. Here’s why HPB is our preferred choice:

  • Consistent Performance: We have found that HPB consistently delivers superior results, ensuring that our installations remain stable and attractive for years.
  • Reliability: HPB’s excellent drainage and load distribution properties align with our commitment to quality and durability in every project we undertake.
  • Customer Satisfaction: By using HPB, we minimize the risk of common issues like water pooling, shifting pavers, or uneven surfaces, leading to higher customer satisfaction.

Exceptions to Using HPB

While HPB is our go-to base material, there are specific circumstances where we might use an alternative:

  • Soil Conditions: In areas with particularly poor soil or high clay content, additional base materials or drainage solutions might be necessary to ensure stability.
  • Design Requirements: Certain design elements or customer preferences might call for different base materials to achieve the desired aesthetic or functional outcome.

"Lift & Relay" Jobs at Treff Landscaping

A significant portion of our work each season involves repairing "builder-grade" interlock driveways, which we refer to as "lift & relay" jobs. These projects typically involve the following steps:

  • Assessment: Identify areas with uneven pavers, poor drainage, or other issues.
  • Lifting: Carefully lift and remove the existing pavers.
  • Base Repair: Address underlying issues with the base material, including re-compaction and adding new gravel as needed.
  • Relay: Reinstall the pavers, ensuring a tight fit and proper leveling.
  • Finishing: Add and compact sand in the joints, and seal the surface if necessary.

Proper Drainage

Proper drainage is crucial to prevent water accumulation, which can lead to shifting, erosion, and damage to the interlocking pavers. Here are some key points to consider:

  • Proper Drainage: Ensure the base slopes away from any structures (like your house) at a gradient of about 1 inch per 8 feet.
  • Drainage Systems: Incorporate French drains or other drainage solutions to manage excess water.
  • Permeable Pavers: Consider using permeable pavers that allow water to pass through, reducing runoff and improving drainage.

Proper Base Material

The base material is foundational to the longevity and stability of your interlocking paver project. Here's what you need to know:

  • Gravel Base: Use a high-quality, crushed stone base (e.g., 3/4-inch gravel) to provide stability and proper drainage.
  • Compaction: Thoroughly compact each layer of the gravel base to prevent settling and shifting over time.
  • Sand Layer: A 1-inch layer of coarse sand over the compacted gravel helps level the surface and secures the pavers in place.
