01 Masonry · Interlocking paving
Interlocking paving, paid on approval.
Interlocking is bought to make a compound usable in the rains. Laid without thinking about where the water goes, it just relocates the puddle to somewhere less convenient.
02 What the job involves
What you are actually paying for
Compound paving with proper falls, edging and drainage.
Also asked for as: interlocking stone · paving stone
- Surveying existing levels and deciding where the water should run to
- Excavation and a compacted sub-base, which is what stops it sinking later
- Sand bedding laid to a deliberate fall rather than flat
- Laying, cutting to edges, and installing edge restraints
- Jointing sand and compaction, plus any channel or soakaway connection
03 What moves the price
Why two quotes differ
Quotes arrive sorted by total, which makes comparison easy and misleading in equal measure. These are the variables worth checking before you decide one is cheaper.
- 01
Area in square metres
- 02
Whether drainage channels or a soakaway connection are included
- 03
Depth of excavation needed, which depends on the existing ground
- 04
Stone thickness — driveways carrying vehicles need thicker units than footpaths
04 Questions
Worth asking first
- 01
How do I stop my compound flooding after paving?
- The fall and the drainage do that, not the stone. Get the levels surveyed first and insist the quote states where water is being directed. Paving laid flat over ground that already holds water will hold it just as well afterwards.
- 02
Why is my interlocking sinking in places?
- Usually an inadequate or poorly compacted sub-base, sometimes edge restraints that were left out. It is a groundwork failure rather than a stone failure, which is why the sub-base depth is worth having written into the quote.
