How to Repair Cracks and Gaps in Block Paved Areas

Block paving is a popular choice for driveways, patios, and paths thanks to its durability, versatility, and visual appeal. However, over time, cracks and gaps can appear due to weather changes, ground movement, or wear and tear. At Hawkhurst Driveways, we help property owners in Hawkhurst, Kent, keep their block paved surfaces in excellent condition by providing expert repair services that restore both appearance and functionality.

Understanding Why Cracks and Gaps Appear

Before starting any repairs, it’s important to identify the cause of the problem. Common reasons for cracks and gaps in block paving include:

• Settlement of the ground – Over time, the sub-base can shift, creating unevenness.
  
• Weather effects – Freeze-thaw cycles and heavy rain can cause movement in the blocks.
  
• Weed growth – Roots can force joints apart, creating gaps.
  
• Heavy use – Frequent vehicle traffic can loosen or damage blocks.
  

Addressing the root cause is key to ensuring the repair lasts.

Step-by-Step Approach to Repairs

1. Clear the Affected Area

Remove any weeds, moss, or debris from between the blocks. A stiff brush or specialist paving cleaner will help ensure the area is clean and ready for repair.

2. Remove and Inspect the Blocks

Lift the damaged or surrounding blocks carefully. This allows you to check the underlying base for any weaknesses, dips, or areas that need re-levelling.

3. Prepare and Level the Base

If the base has sunk or shifted, add and compact sharp sand to bring it back to the correct level. A firm, even base is essential for preventing future gaps.

4. Reinstall the Blocks

Replace the original blocks, or if they are damaged, fit matching replacements. Make sure they are aligned correctly to maintain the pattern and overall appearance.

5. Re-Sand the Joints

Brush kiln-dried jointing sand into the gaps between the blocks. This locks them together and helps prevent weed growth.

6. Compact the Area

Use a vibrating plate compactor to settle the blocks back into place and ensure the joints are tightly packed.

Preventing Future Damage

To extend the life of your block paving and reduce the need for repairs:

• Keep joints topped up with jointing sand.
  
• Apply a quality sealant to protect against weeds, stains, and water damage.
  
• Regularly remove moss and weeds before they take root.
  
• Avoid overloading the paving with excessively heavy vehicles.
