So many homes throughout Kent still have ageing concrete drives that have seen better days. Cracks, staining, uneven patches, and poor drainage are very common. If you are dealing with these problems, converting your existing surface into block paving can be a practical and long-lasting upgrade. For homeowners exploring paved drivewaysin Kent, this is a more realistic option than a complete rebuild from scratch.
Is It Possible to Build Over an
Existing Concrete Driveway?
Block paving can be installed
over the top of an old concrete base in some instances, but again, it is
totally dependent on the actual condition of that base. The concrete does have
to be structurally sound, level, and free of major cracks or any movement in
it. If the surface has begun to sink or break apart, it generally will need to
be removed.
A proper assessment looks at
drainage, levels, and whether the existing concrete allows enough depth for the
new layers required for block paving. A common problem with most jobs is that
this step is usually skipped, leading to future problems such as sinking or
loose blocks.
When to Remove the Concrete?
If there is evidence of
structural failure, like widespread cracking, pooling water, or uneven
settlement on the surface, removal of concrete is required. Removal will add
extra time and money, but it gives the ability to rebuild the driveway
correctly from the ground up.
Once removed, the correct depth
of the ground can be excavated, a new sub-base installed, and proper drainage
built in. This method offers a much more sound finish, without repeating old
problems under a new surface.
What Does the Conversion Process
Entail?
There are several steps to
convert a concrete driveway to block paving. It includes excavation where
necessary, laying a compacted sub-base, adding a layer of sharp sand, and
laying paving blocks precisely. Edge restraints are required to hold the
driveway together over time.
Drainage is also checked at this
time. Most of the older concrete driveways were installed before modern drainage
guidance, so changes may be needed to stop water from running toward the
property.
Why Homeowners Choose Block
Paving Over Concrete
Block paving offers a flexibility
that concrete cannot. It is possible to lift individual blocks and re-lay them
if access or repairs are required in the future. Aesthetically, it is neater
and looks modern, with options for both traditional and modern homes.
For homeowners considering paved
driveways in Kent, block paving is often chosen because it balances
appearance, durability, and practicality.
Is Conversion the Right Choice
for Your Driveway?
Not every concrete driveway is
suitable for conversion, but many are. The key to this is proper evaluation
before work begins. When it's done right, replacing concrete with block paving
can solve long-standing issues, adding value and improving everyday use of your
home.
