100mm perforated pipe... recommendations

[JackOrion]

We've got a 3m high gabion wall going up behind the house. Gabion designer has specified:

 

"Wavin or similar perforated coil drain 100 Ø mm"

 

Struggling to find Wavin products anywhere (rebranded as Osma?)

Any brand recommendations from here? Unconvinced by stock at the local builders merchants. Naylor / Brett Martin have come up online... any thoughts appreciated.
