Sunken and rutted block paving in Cardiff: what to expect
Across Cardiff, front gardens range from narrow terrace plots to broad modern drives, and the best block, pattern and drainage choice changes with them.
Wales is wetter than most of England, and new front paving has to be permeable or drain within the property, so drainage is designed in from the start.

What is included?
Common causes are a sub-base that was too thin or not compacted, a laying course that was too thick, water washing sand out through a broken drain, or a trench that was never properly filled. Re-levelling means lifting the blocks in and around the dip, finding and fixing the cause, rebuilding and compacting the layers, and relaying the same blocks so they match.
- Sub-base dug out and rebuilt where it has failed
- New laying course screeded to the correct level and falls
- Blocks lifted, cleaned and stacked for re-use
- Investigation of the cause (drain, sub-base, laying course, edging)
- Same blocks relaid, re-jointed and compacted

- Condition and thickness of your existing blocks

Sunken paving in Cardiff: questions
Can you send someone just to look?

Can you repair block paving in Cardiff without replacing it?
Usually, yes. We lift the affected blocks, fix the bed or base, and re-lay the same blocks so the repair matches.
Why does block paving sink?
Most dips come from a thin or poorly compacted sub-base, too much sand under the blocks, failed edging, or water washing material out from a broken drain.
