Hi Womble - it's a success!!
It has made SUCH a difference around the ring feeder and has given a decent solid base for the cows...and us.
I just wish we had bought more as I have ended up face down and bottom down in the knee-deep mud between the haylage bales and where the rubber matting starts when refilling the ring feeder but as soon as I get to the matting I can walk normally.
I know what I'll be spending my SFP on this year - more matting for the cows and also the sheep, it might be expensive but then again if it means fewer trips to the osteopath it's worth every penny. It has really distressed me to see the sheep wallowing in so much mud this winter - I'm just relieved that I can do something about it next year.
