How to fill gap under concrete driveway?

Under my concrete driveway there is a gap, what's the best way to fill it up? For now I have just placed pavers but would prefer a permanent (and better) solution).

Re: How to fill gap under concrete driveway?

Hello @smhok 


It seems that the last batch of heavy rain has eroded the soil beside your concrete driveway. In order to shore it up, I suggest building a small retaining wall out of sleepers to prevent soil erosion in that part of the driveway. I also recommend putting in Vinidex 100mm x 20m Socked Slotted Draincoil inside the retaining wall to re-direct the water falling into it.


I've placed a sample sketch below to give you an idea of what it looks like and how you can build it. 


If you have any questions about it, please let me know.
