How to fill this gap between retaining wall and concrete?

[ashleasmith]

Getting a bit sick of having grass grow through this gap into my garden bed! It’s kikuyu grass and spreads so easily, so I need to stop it!

Any suggestions on how to fill this gap?

Hello @ashleasmith 

Thanks for sharing your question about filling the gap in your retaining wall. I suggest tipping some hot boiling water specifically just in that gap. Be extremely careful not to burn any of your turf except that spot. The hot water will burn the turf all the way down to the roots. Clear out the area and then use another piece of timber or a timber wedge a flat rock or mortar to fill the gap.

Please remember to wear personal protection such as gloves and goggles when working on your project.

If you need further assistance, please let us know.
