No further information on this operator.

All details confirmed correct, I have asked for some test results.

I have phoned them but the line was automatically disconnected. I have sent them an email.

Has been taken over by Blockstone.

No response via phone, website doesn't work and email has bounced back.

I have discovered that this operator is no longer in business and their quarry, Leeming Quarry, has now been taken over by Breedon Aggregates Scotland Ltd.

Stated they were a small company and did not want to be advertised.
