Liquid Waterproofing Group

About Us

The Liquid Waterproofing Group operates as a specialist company and is able to deal with all civil engineering and mining water leakages of all types derived from a uniquely experienced background of the toughest engineering environments.

We have an experienced engineering team with an exceptional level of expertise in concrete technology and construction, water control, support and stabilisation techniques.

By retaining a specialist approach, the company is able to deliver on time and within budget and has strict quality controls over all aspects of the operations.

All our components are tried and tested under extreme pressures with high volume water flow. These very high pressures are only limited by the grout pumps itself. Pressures of up to 50 Bar can easily be achieved.

Core Competencies

Leaders in modern technology solutions since 1999.

The Liquid Waterproofing Group developed water-based polymer components to stop water in mines and subsequently refined our solutions for structural applications.

Don't be misled.
Not all 'injection waterproofing systems' are equal.

Providing proven solutions for failed traditional waterproofing methods.

Addressing the sources of the ingress problem, the results can be far more accurate and measured.

Far less intrusive remedial solutions to existing water ingress.

Much quicker compared to alternative conventional waterproofing. We seal unwanted water with little to no disruptions to our client's operations, cost effectively and without delays.

Providing our clients with technically advanced quality products and services while complying with all health, environmental and safety regulations.

Gautrain Tunnel Sealed

Gauteng South Africa

Liquid Waterproofing was contracted to seal the water leakage in the Gautrain tunnel system.

The successful sealing of the Gautrain tunnel in the vicinity of Park Station allowed the station to open for business.

This includes the tunnels from Park Station to Rosebank Station, Rosebank Station to Sandton Station and Sandton Station to Marlboro Station.

Ghaghoo Mine Sealed


"Interestingly, the company comes highly recommended by Clifford Elphick, CEO of diamond producer Gem Diamonds, who, after unsuccessful attempts at sealing a massive fissure at its new Ghaghoo diamond mine in Botswana, turned to Liquid Waterproofing for a solution."

Various fissures have been intersected by cover drilling decanting approximately 2500 to 8000 litres per hour at pressures of approximately 11 bar through a 50mm casing pipe. The highest pressure encountered was 27 bar.

All these fissures have been pre-sealed with chemical grouting through pre-drilled holes in the face which intercepted the fissure. Grouting distance varied between 8 and 15m. ...

Mopani Mine Zambia

Mindolo Shaft

The development in the lowest section of the mine, stretched through a waterbearing aquifer with water temperature measuring 60 to 70 degrees Cels.

Cementation of the drilled holes took to long to set and progress was too slow.

Liquid Waterproofing undertook the chemical grouting under extreme conditions and sealed the water as development continued.

Interestingly enough during this sealing exercise another area that had been water stricken some 110m above had also dried up and is no longer a problem

On all of these occasions Liquid Waterproofing have been successful in effectively sealing these water intersections and allowed for the development of the haulages and crosscuts to continue in a timeous fashion
