The crack repair that was done on my tank at Loch was great and the tank is now full, with no leaks. No need to empty tank water which was a god send.

Hi Darren,

Just to let you know the tank is holding well - now about one third
full and no leaks.

From Jim Usher, St Andrews
There was a small hole about 50cm from the bottom of my concrete tank
which I couldn't repair with conventional commercial products, mr crystal or xypex. Water
was just running away and it meant I could only rely on having use of
about 10,000 litres in a tank that holds 65,000 litres when full. The
Tank Shop repaired the leak and a couple of other small ones with what
I can only describe as a "revolutionary" procedure. I can now expect
full use of the 65,000 litres.

Will keep in touch, and thanks for your good work on the tank.



We have had a crack in our tank for a few years now & we had previously been told that we would have to empty the tank to have the leaks repaired. We were never keen to do this with the dry seasons and having to refill our tank.

We recently visited Farm World at Warragul & noticed “The Tank Shop” stand in which we were able to have Darren come out to our tank & inspect it with recommendations to repair the 1.8 metre crack which over time had constant water running down the face of the tank not only causing loss of water but an ongoing mildew slime mess area around the leak and bottom of the tank.

I’m delighted to say that Darren came out within 2 weeks & repaired the crack within one day and most importantly without a drop of water being wasted.

Darren also has provided further recommendations to ensure the life of our tank.

Thank you Darren and we would highly recommend you for any concrete water tank leaking problems.

Yours Sincerely

Good afternoon Darren,

I just wanted to let you know that the repairs that you did to the Concrete Water Tank up at Yinnar South have done the job. It is now nearly full again after all the rain and it shows no sign of leaking or seeping.

I must admit that I did not think that you would be able to repair without emptying the tank and doing it from the inside as well as out as one of the lower cracks was quite large but you proved me wrong.

Your repair work has saved me a lot of trouble and considerable expense and I thank you for a job well done. I certainly would have no hesitation in recommending the effectiveness of your repair process.

Kindest Regards

There was a 2.7 Metre crack, plus several smaller ones in our tank that were leaking a lot of water causing bogginess in quite a large area, After speaking with Darren he promptly came out to repair it. After treatment to my amazement the water has stopped leaking and the ground has started to dry out. Thank You Darren, I would not hesitate to recommend you to anyone who has a tank problem.

My 95Kl concrete water tank developed vertical cracks which became leakers and did not self-seal. Tank Shop sealed the cracks and fitted steel bands around the tank to prevent any further cracking. The workmanship was very professional and I am really pleased with the result.

Ray Marston, Boolarra

We are in a rural area where the only water supply is what we catch from our roof areas.

We have 4 x 7000 gal concrete tanks for storage.Two of the tanks, poured on site more than 30 years
ago, had numerous and extensive cracks all leaking at a disastrous rate.
Many of the cracks were several metres in length, some from top to bottom of the tanks, some radial and some diagonal.

After many attempts at DIY repairs including internal concrete buttressing and paint-on solutions, the tanks were still so leaky that we were faced with having to put in new ones, a very difficult exercise as we had no suitable areas to put them in.

With only half our average rainfall in 2014 and a hot,dry summer predicted, water was becoming a big issue.
We had Tankshop look at the situation and decided to go ahead with their method and after 19.5 linear meters of cracks had been treated we were amazed that all the leaks had stopped completely.

Many months after the treatment all the leaks have dried up totally and show no sign of weeping at all. We are completely amazed at the effectiveness of this treatment on what were otherwise useless tanks fit only for demolition. Thankyou Tankshop!

2012 - Awesome job on my tank Darren. Thank you very much for responding so quickley. Janice Bostedt ( Driffield Gippsland )

To anyone reading this, we cannot stress enough what a huge relief it is to know that our cracked tank is fixed. It created a smelly mosquito infested lagoon that seeped into the sewerage run off pipe and was dreadful. In addition, the thought of how much water we have lost over the years is a puzzle. Thank you Darren. Thank you. We will be singing your praises to all who will listen! Already we have passed your business card out.

Sincerely and thanks

2013 - Hello Darren

Just a quick email to thank you for a super professional job on our tank. I was sceptical about your method when everyone else wanted to remove the cover, drain the tank and paint it or put in liners or dig it out of the
slope or otherwise spend many thousands of our money and make us move out of the house for a few weeks (hotel ?). But dealing with you was a pleasure, you did everything you said you would and the results are amazing. There are
no leaks now, the tank seems very happy and we are happy having spent well under liner install pricing including your transport and GST. You were here half a day including clean-up of your tools.

I would be very happy to endorse your service based on our excellent experience.

All the best

I knew it was time to take action on significant leaks in our 30,000 gallon domestic water tank and was looking at some seriously costly options and the potential loss of a full tank of water when I found Darren’s website.

Seemed almost too good to be true but certainly worth a chat, so I made a phone call. Whoops, would have been smarter to read the instructions on the Website first and taken the measurements. The return call was pleasant, brief, efficient and gave me the estimated cost and a potential date for the job. It was a largish job 14M of cracks hidden behind agapanthus and other shrubbery.

The day arrived, on time and proceeded to unload and get on with the job at hand, no problems, no fuss, clearly very experienced at what they do.

I was, no leaks, a full tank of water and very effective, cost efficient outcome.

The best part though was that all of this happened as promised, quality workmanship, on time, within the quote. It was, as the old advert went “like flying with British Airways” all done with a minimum of fuss.

I am more than happy to recommend TankShop to anyone looking to save their tank and more importantly their water.

Thanks guys, a job very well done!
