Sovereign Hydroseal has been dedicated to the field of water proofing since 1972, specializing in water sealing systems with a high flow rate / volume and leaks with a rate of 9900 Lt per minute at 180 P.S.I.

However, the company’s waterproofing technology has also found its applications in the field of civil engineering. An example of this is The Afrikaner, an iconic monument in South Africa which has been leaking water since its construction in 1949.

The building is a concrete structure with heavy granite cladding. After a 12 month testing phase, Sovereign submitted a remedial proposal and application of the company’s waterproofing technology and work commenced 2 months later. Due to the fact that hardly any plans were available, Sovereign had to investigate the construction methods and building material of that time. Hundreds of core holes were drilled, samples taken and tested. All water bearing fissures were mapped on a virtual program and fractures, voids and delaminating areas identified. This information was used to ensure that the entire building was sealed once repairs commenced.

The Monument was waterproofed by injecting a specialized emulsion into the drilled holes and all voids, cracks and water migration conduits were sealed. On completion of the project tests were conducted by simulating rain. A custom built irrigation system, delivering a metered 70 000 litres of water per shift, was constructed on the outer horizontal surfaces.
No excavation took place to waterproof it and the project was declared a success once the appointed civil engineer completed his final inspection.
