"Having an older, small pontoon I was interested in renovating and enlarging rather than investing in an expensive new product. I consulted with a few suppliers but Stu from Cobalt assessed my situation and came up with a great solution that satisfied my needs but didn't cost a fortune. The job went smoothly and I now have exactly what a I needed at a fraction of the cost of the equivalent new product. Highly recommend Cobalt."



"We would like to extend our appreciation to Cobalt Civil Pty Ltd in undertaking a comprehensive  programme to refurbish and extend the life of our registered Helipad.


It exceeded our expectations when Stu arrived on time and proceeded to advise us in his opinion as to what treatment was required to carry out the works.


It was a pleasure to work with Stuart and his team. Complete care taken to give us the end result that was most satisfying to us. We would have to hesitation in recommending Cobalt Civil Pty Ltd to anyone who required a very honest and trustworthy Company for excellent advise and work procedures, at a very fair price."

"We have used Cobalt Civil now on several occasions to rejuvenate an aging pontoon and also make some personal adjustments to accommodate our changing needs. We have found Stu and his team highly professional in the delivery of a quality end product. In utilising this company, we found that at all times they were open and astute in their communication which enabled us to achieve the desired result. Their reliable and prompt service combined with their competitive price is the reason why we will continue to use Cobalt Civil in the future."
