CONCRETE Crack injection is commonly used in residential and commercial applications primarily because it is far less expensive than emptying tank water, cleaning out the interior of the tank, then drying the inside surfaces out as well as grinding all surfaces smooth. 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 concrete crack repair system.

FOR A QUOTATION - Please take a photo of the whole tank from further back and leaking cracks as well, email or text that information through to This email address is being protected from spambots. You need JavaScript enabled to view it. or 0427 427 183

Concrete Water Tank Leaks Repaired - No Water Loss, Flexible, Strong, Durable, External Pressure Injection Sealant.


What makes it work ?

Crack Injection is a fluid sealant which is injected into concrete cracks, rock fissures, expansion joints and other voids in concrete structures. When used in concrete crack injection applications the sealant is injected into a crack; within minutes the sealant expands transforming from a liquid to a flexible rubber solid. Flexible, Very Strong and Durable being the key, Potable Food Grade Sealant for drinking water, with a extremely high adhesion rating. The sealant will expand and contract with future concrete movement. Concrete is subject to weather conditions and will expand and conctract along with these conditions, very similar to house foundations and brickwork.


The Sealant is attracted to water - making it work amazingly well in situations where there is water actively leaking ( flowing ) out of cracks at a high flow rate. You will be amazed at some of the high pressure leaks we have repaired, ( refer to our website and linked facebook pages for examples ), no need to empty tank water !

Very Happy Clients ! Tank Leaks Repaired without Emptying Water !

February 2016

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 wit


2013 - Client Reference. Valerie BRENNAN, Greta West ( Near Glenrowan ), Victoria 3675

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 measuremen
