Sorek Desalination Plant
South of Tel Aviv,
Israel
The project used over 300 tonnes of Xypex C-500 NF Admixture as well as Xypex Concentrate and Xypex Patch’n Plug for joints and other works. Xypex is proud to have been a part of this highly successful project.

This plant takes water from the Mediterranean
Sea, removes the salt to create fresh, potable
water and ejects the high salt brine back to
the sea. The water feed lines (2 separate
pipes) and the brine ejection line (one single
pipe) combine for a total combined pipe
length of approximately 9.7 km. The pipe
sections are thick walled pre-cast pieces that
were “pipe-jacked” from a launch site on land
through an excavated tunnel under the sea
bed.
After thorough investigation, the project design team chose to include 1.5% of Xypex C-500 NF Admixture in the concrete mix to both heal cracks as well as improve the overall chloride durability of the pipe. As the pipe was jacked into place visible leaking was seen in the pipe sections. All visible leakage was seen to heal and the project became so impressed with Xypex’s crack healing ability that the use of the Xypex Admix was extended in the project to include most of the water processing and holding structures as well as the pipe.

There was concern that with the stresses induced in the pipe during both transport from the precast yard to the site and then especially during the pipe-jacking cracking in the pipe would occur. It was expected that this cracking combined with the high brine environments in the pipes would cause rapid chloride degradation of this critical piece of infrastructure.
