compost not holding moisture. Hydrophobic?

Hi
Bought in a load of compost for No Dig beds which looked fine on the WET day it was delivered.
Now had first rain for 6 weeks and only top 1cm is damp after 2 days of consistent light rain - totalof 26mm so far.
Internet quick search seems to suggest it could be hydrophobic. Don't really want to dig the compost into soil as it's 10cm deep and aim is for No Dig system.
Any ideas on resolving this issue (ideally a quickfix as have cold frames full of transplants to go out) would be much appreciated. Got around 70m2 of raised beds that need "repairing"
Thanks

This guy uses ecos dish soap in his potting mix blend to make it absorb water. Maybe try that on a small patch and see if it helps?

Thanks. I've given it a try. I will wait and see for a few days to see how quickly the beds dry out after this rain.
