Craig and his team did an excellent job on our foundations recently. Their work was thorough and of a high standard, and left the property neat and tidy. Their communication was friendly and efficient, and I would have no hesitation recommending them for grout injection. Thanks Guys.

Craig from Coastline Chemical Grout Injection is a top bloke! I'm installing a pool 600mm to my house and require Grout Injection to prevent my house from falling into the pool.After multiple calls to outsource the job, Craig gave me a precise quote over the phone which has saved me thousands rather than going with the pool company and other Chemical Injection contractors.He worked to my schedule, was on time, very friendly, fully explained the process of this work. He also was very careful as to leave a tidy site and not damage my property in anyway.Highly recommend Craig and his team for the work they do.

I tendered out an underpinning job on a house I was renovating and Craig and Coastline Chemical were the only ones that actually provided a decent response. Craig called straight away and from that he provided a detailed quote with technical doc's attached. His pricing was also better than the few others I actually got quotes from, after chasing several times! He did the job efficiently in a few hours on a day and time of my choosing. All good, everything's rock solid and I would highly recommend them.

Only one company responded.Craig & Nathan responded within a couple of hours, to arrange a time to meet on site.I received a quote which I accepted & found both men very professional & knowledgeable.They explained clearly how my problem could be fixed so we booked a time a few days later.They came on site on time, completed the work & cleaned up thoroughly.I would recommend without hesitation, Craig & Nathan score 10/10 for every aspect of their work & customer service.
