In early 2017, Sanika Waterproofing Specialists completed a mammoth concrete repair and rejuvenation project at the Goedehoop Colliery Block 7 mine ventilation downcast shaft.
The shaft had experienced the major ingress of water over the last 35 years with a notable increase in the last couple of years through the joint interface, posing potential flooding and deterioration to the existing concrete shaft liner.
The excessive leaks were being pumped out on a daily basis as part of a routine operation which was required for the normal running of the mine.
Early in 2017, the underground build-up of water broke through the concrete ventilation shaft, allowing excessive water penetration into the mine.
Based on all information gathered during the investigation stage, Sanika Waterproofing Specialists concluded that the Kryton Leak Repair System was the best course of action for a project of this magnitude. The solution to the water ingress points was a huge success and the Goedehoop colliery has not experienced any leaks in the Block 7 mine ventilation shaft since the repair.
This case study was submitted to the International Concrete Repair Institute (ICRI) in Kansas, USA where a diverse panel of judges presented Sanika with an Award of Excellence and nominated our Goedehoop concrete repair project as a finalist for the 2018 Project of the Year. We will be travelling to the 2018 ICRI Project Awards held in Nebraska, USA in November 2018 to present our Goedehoop concrete repair project and receive our Award of Excellence, while standing a 1 in 3 chance of winning a world renowed Project of Year.
This Award not only has a huge impact for Sanika Waterproofing Specialists in the Concrete Industry, it also has an impact on the South African business community as a South African company is being recognised amongst the best in the world.
