Crack injection is commonly used in residential and commercial applications primarily because it is far less expensive than excavating a foundation and waterproofing the exterior foundation wall, floor slab, carpark, tunnel, bridge, pit, channel, drain. There is also no need to remove tiles and other finishes from the surface in order to fix leaks. Crack injection is the most reliable leaking crack repair system when done properly.
Used to repair leaking concrete joints / cracks in - concrete carparks, tunnels, bridges, water treatment plants, pits, dams, tanks, apartment buildings, undergound cellars, retaining walls, factories, tilt slab concrete constructed buildings, and more.
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 19.5m of cracks had been treated we were amazed that almost all the leaks had stopped completely.
Two 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!

8 years ago now we repaired the tank below - still going strong !!!!
2013 - Hello Darren
Just a quick email to thank you for a super professional job on our tank. I was skeptical 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

Just had our leaking concrete water tank repaired by Darren very happy with the result. We initially tried to fix it ourselves with a product from the local hardware store which cost over $150. which was a waste of time and money. thanks Darren a job well done.

My 40,000 litre concrete tank had a slow leak from a crack extending the full height of the wall and finally deteriorated to the extent that there was a steady flow of water streaming from it. TheTankShop came and repaired the leak quickly and efficiently and the crack which had been damp for years is now completely dry. Very pleased with the result and would highly recommend TheTankShop.
2011 - 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

Injection Leak Sealant - was used to repair a cooling tank at the Geelong Galvanising Plant. The process was carried out on all visible cracks from the inside of the tank reservoir, as you can see from our photos. The cooling tank is used after the steel is removed from the furnace to cool the steel once galvanised. The water temperature inside the tank can be up to 90 oC once steel has been cooled.
