Covering up uneven messy concrete slabs with Gravel Grids. Need Your Advise

Anonymous user 08/12/2025 - 8.06 AM

Hello everyone, I'm having a meltdown deciding what to do to improve the look of my garden without breaking the bank. My question is can I cover this area of my garden by laying down gravel grids and fill it up with gravel? Few notes: * I don't have a good access so ideally want to avoid redoing it from scratch by removing the slabs and laying crushed concrete etc.... *I can't deck the area without getting a planning permissions! *I'm aware of the manholes and accessing them won't be an issue with bit of gravel on top * I'm not sure where the DPC is, since the flat is rendered but I assume it's further up. *I haven't had any drainage issue so doubt I'll need to create drainage. My questions: What would be best way to level the surface? Would it be better if I lift off the slabs, level them with the crushed concrete or sand and put them back in? what would you suggest as leveling material? Can I level the surface pouring crushed concrete or maybe sand on top then put a membrane and the grid and gravel on top? Will rain possibly wash them and make the surface en even after a while? Thank you ever so much

1. Lift the slabs that are rocking or uneven. You don’t need to take every slab up, just the problem ones. 2. Level the ground beneath them using sharp sand or fine Type 1 / granules. Sharp sand works if the slabs are going back on top of it. Do not use soft building sand—it moves. 3. Relay the slabs and whack/seat them firmly. You don’t need perfect paving quality here; just stability. 4. Lay a geotextile membrane (to stop weeds and gravel sinking through gaps). 5. Lay your gravel grids. 6. Fill with gravel (10–20mm works best).

The “grids on top of slabs + gravel fill” method is the best compromise between cost, effort, and looks. Just spend time making the surface as level as possible before laying grids, and don’t build up above the DPC.
