I did tis but worried it would stop drainage even though I deliberately left the last few inches in soil then post crete from there up. The postcrete did not seep through the gaps and block the drainage luckily.
Just bought 60m one from Wilko for £30. I am happy with the quality
That’s a great idea I think! (y)
The version with the included cover is £75 from Costco.
