Is Your Block Paving Sinking? What to Do About It
Block paving is one of the most durable and visually appealing options for driveways, patios, and pathways. However, over time, you may notice certain areas starting to dip or sink. This not only affects the look of your driveway but can also create safety issues and drainage problems. At Great Yarmouth Driveways, we often help homeowners identify the cause and put things right quickly and professionally.
Why Does Block Paving Sink?
There are several common reasons why block paving might start to sink:
- Poor Sub-Base Preparation – If the ground wasn’t compacted properly before installation, voids may develop beneath the surface.
- Drainage Issues – Water pooling beneath the paving can wash away supporting materials, leading to sinking.
- Heavy Loads – Consistent use by heavy vehicles can compress the bedding layer over time.
- Tree Roots – Roots growing under the surface can disrupt the structure, causing unevenness.
The Risks of Ignoring Sinking Paving
Leaving the issue unaddressed can lead to:
- Tripping hazards for pedestrians
- Water pooling and increased risk of flooding
- Progressive damage that makes repairs more extensive later
- A driveway that looks aged and neglected
How to Fix Sinking Block Paving
The good news is that sinking block paving can usually be repaired without replacing the entire surface. At Great Yarmouth Driveways, our repair process typically includes:
- Lifting the Affected Blocks – Carefully removing the sunken blocks to prevent damage.
- Re-Levelling the Base – Adding and compacting fresh sharp sand to restore a level surface.
- Re-Laying the Blocks – Putting the original blocks back in place for a seamless look.
- Jointing and Compacting – Sweeping in kiln-dried sand and vibrating the surface to lock everything together.
Preventing Future Sinking
You can help prevent the problem from returning by:
- Ensuring good drainage is in place around your driveway
- Avoiding consistently parking heavy vehicles in the same spot
- Scheduling periodic maintenance to re-sand and seal the surface
- Trimming back tree roots near paved areas
