Interested to pick your brains.
I am doing some car park surface drains - down in Haverhill, on a store clean.
The drains are the slit ones that have an interceptor (sump) every 15 metres, 4 inch diameter and normally we flush them through, lift the debris from the interceptor and then repeat till clear.
Next to the service yard I have got a 10 metre section between interceptors that seems to have had cement dropped down it or a sand and powder mix that has set.
Will a root cutter get through this or do I need to get something else. Not a mega problem if you don't know but I have tried to break it up with a thin steel bar we use but to no effect
Cheers
