Remedial Leak Sealing

Concrete Leak Sealing Injections


Waterstop Solutions specialises in stopping leaks and seepage with chemical pressure grouting. This high-pressure injection system fills and seals leaking cracks and joints in concrete structures, such as concrete slabs, tanks, pools, reservoirs, underground car parks and basements.


We offer our expertise in concrete leak-sealing injection services to the East Coast of Australia in Queensland and New South Wales, with offices located in Brisbane and Sydney.


Leaks and seepage can spring from an array of external and internal sources. Water can easily seep through compromised sealing in block work, retaining walls, construction and expansion joints, movement cracks, and pipe penetrations. Leaks may be evidenced by elevated moisture levels, efflorescence and temperamental or active water leaks.


At Waterstop Solutions, our highly-skilled technicians frequently perform remedial high-pressure leak-sealing injection to stop water seeping into building structures.  Whilst other remedial companies may average once a year (or at most once a month), our technicians perform quality high-pressure leak-sealing injection work several times per week.


Our technicians are fully qualified to perform expert remedial leak-sealing injection using specialised leak-sealing systems, designed to stop water seeping into your concrete building/structure – whether it is through the block work of a wall or rising up through a concrete floor slab in your basement.
