Are you looking to enhance your home’s exterior with a stylish and durable driveway or patio? Block paving might be the ideal solution. Not only does it provide a robust and attractive surface, but it also adds value to your property. The best part? You can do it yourself! This comprehensive guide will walk you through the entire process of installing block paving, from planning to completion. Let’s get started!

Why Choose Block Paving?

Block paving offers several advantages:

  • Durability: With proper installation, block paving can last for decades.
  • Aesthetic Appeal: Available in various colours, shapes, and patterns, block paving can complement any home style.
  • Easy Maintenance: Individual blocks can be replaced if damaged, making maintenance straightforward.
  • Environmentally Friendly: Permeable options allow water to drain naturally, reducing surface water run-off.

Tools and Materials Needed

Before you begin, gather the following tools and materials:

Tools

  • Tape measure
  • String line and stakes
  • Shovel
  • Wheelbarrow
  • Plate compactor (available for hire)
  • Spirit level
  • Rubber mallet
  • Trowel
  • Screeding rails and board
  • Block splitter or bolster chisel
  • Brush

Materials

  • Sub-base material (MOT Type 1)
  • Sharp sand
  • Block paving bricks
  • Edging restraints
  • Jointing sand

Step-by-Step Installation Guide

1. Planning and Design

Start by planning the layout of your block paving. Draw a sketch of the area, including dimensions and patterns you wish to use. Calculate the number of blocks, amount of sand, and sub-base material required.

2. Marking Out

Use a tape measure, string line, and stakes to mark out the area. Ensure the lines are straight and true to your design.

3. Excavation

Excavate the marked area to a depth of around 200mm (20cm) for driveways and 150mm (15cm) for patios. This depth includes the sub-base, sand layer, and block thickness. Remove all vegetation, rocks, and debris.

4. Installing the Sub-base

Fill the excavated area with MOT Type 1 sub-base material to a depth of about 100-150mm (10-15cm). Use a plate compactor to compact the sub-base material thoroughly. This layer provides the foundation for your block paving.

5. Laying the Sand Layer

Spread a layer of sharp sand over the compacted sub-base to a depth of around 50mm (5cm). Use screeding rails and a board to level and smooth the sand. Ensure the surface is even and allows for adequate drainage, with a slight slope away from buildings.

6. Laying the Blocks

Start laying the blocks from one corner, working your way across the area. Place each block gently onto the sand, ensuring they are tightly packed together. Use a rubber mallet to tap the blocks into place and a spirit level to ensure they are even.

7. Cutting Blocks

You may need to cut blocks to fit edges or around obstacles. Use a block splitter or bolster chisel to make clean cuts. Always wear appropriate safety gear when cutting blocks.

8. Installing Edging Restraints

Install edging restraints along the perimeter to keep the blocks in place. Secure the edging with concrete or steel spikes, ensuring they are level with the blocks.

9. Compacting the Paving

Once all blocks are laid, use a plate compactor to compact the entire area. This ensures the blocks are firmly set into the sand layer. Cover the surface with a thin layer of jointing sand before compacting to fill any gaps and prevent damage to the blocks.

10. Jointing the Blocks

Spread jointing sand over the entire surface, sweeping it into the gaps between the blocks. Ensure all joints are filled. This step locks the blocks together, providing stability and preventing weeds from growing.

11. Final Compaction

Perform a final pass with the plate compactor to ensure the jointing sand is well compacted and the blocks are securely in place. Top up with more jointing sand if necessary.

Maintenance Tips

To keep your block paving looking its best:

  • Sweep regularly to remove debris and prevent moss growth
  • Apply a weed killer periodically to prevent weeds
  • Re-sand joints as needed to maintain stability
  • Pressure wash occasionally to remove stubborn dirt and stains
