Atlas Concrete Ltd.
“Our main supply for bulk cement over several years has been Thomas Armstrong. From the initial meetings with David Lake, it was clear we were negotiating with a professional who truly understood our business needs. David is always available to resolve any issues promptly, of which there have been very few.
We would highly recommend Thomas Armstrong for bulk cement supply.”
