Transportation is of the utmost importance in any growing populous across the world. Growing cities and populations need to be mobile across a region in a responsible manner, expanding local communities and reducing the carbon foot print, to name a couple benefits.
Throughout the world, innovative design and methodologies are being used to bring innovation to the forefront. Many of these innovations go towards ensuring concrete doesn’t deteriorate in high-risk environments where hydrostatic water pressure is an issue.
For instance, the Monterrey subway line 3 contractors, Maiz Mier, a group who has been using Kryton waterproofing successfully on many projects, knew water pressure was going to be a factor. Originally, all areas of line 3 were specified with external membranes that would end up facing hydrostatic water pressure. Unfortunately, external membranes have limited success rates in these applications which could cause detrimental leaks and leave the project at risk. As many stations were built underground, leaving the concrete at risk by not using the proper waterproofing technology was not an option.
Kryton Distributor, Kalte Waterproofing advised the use Krystol Internal Membrane (KIM) waterproofing admixture all underground tunnels. Not only was KIM able to save time and money on the construction schedule, but also eliminated the risk associated with installation. Further, Kryton Waterstop was also used in conjunction with a PVC Waterstop to ensure a watertight and durable concrete structure.
The 7.5 KM Monterrey Subway line 3 is scheduled for completion later this year and help serve over 4-Million Monterrey commuters.
