Installation Process

A person is laying stone pavers on a prepared base, ensuring each piece is level and tightly packed. They are using a rubber mallet to tap the pavers into place and a level to check for evenness

When embarking on a paving stone project, it’s crucial for us to focus on a solid installation process. We will guide you step by step, from preparing the base to the final touches of compaction, drawing on established practices like those recommended by Unilock’s Technical Guide.

Preparing the Base

Our initial step involves creating a sturdy and level base which is critical for the longevity of the paver install.

  1. Site Excavation: We dig to the suggested depth which, depending on the project, is typically between 7 to 10 inches below the desired final surface level.
  2. Grading: We ensure the grade is sloping away from any structures for proper drainage.
  3. Base Material: We lay a base using crushed stone; typically, 4 to 8 inches thick depending on usage.
  4. Compaction: Using a plate compactor, we compact the base material in layers to avoid settling.

Laying Paving Stones

After the base is prepared, we dive into setting the paving stones in place.

  1. Setting Bed: We spread a layer of sand, usually about 1 inch thick, to lay our stones on.
  2. Placing Stones: Stones are carefully set according to our planned layout, keeping gaps even.
  3. Leveling: As we work, we ensure that the stones are level and align with the existing pattern.

Applying Sand and Final Compaction

The sand serves dual purposes: it secures the pavers and fills the joints. For a natural stone path or other intricacies, this step is essential to the paving process.

  1. Joint Filling: We sweep sand over the pavers filling the joints completely.
  2. Vibration Compaction: With the sand in place, we do a final compaction to settle the sand in the joints and ensure the pavement is flat and stable.
  3. Sealing (Optional): For projects requiring extra resilience and a polished look, we recommend applying a sealer.

Throughout each stage, our team frequently references the Outdoor Idea Center for current trends and the best applications for our projects. The adherence to this systematic process ensures the durability and aesthetic of the finished project.
