Perfect Leakage Prevention Even at Minus 40 Degrees and 100m Underground Pressure

#. On the 22nd, at the performance demonstration site of 'Turbo Seal' at Rinew System's Yeoju Campus in Yeoju, Gyeonggi-do, when the adhesive gel was pressed, black waterproof material spread between metal plates. Every time the compression rod of the experimental device moved up and down, the black substance did not tear and returned to its original state. This is Turbo Seal, a high-adhesion non-curing gel waterproof material developed by Rinew System for the first time in the world. It is evaluated as an alternative that overcomes the limitations of existing waterproof technology by not tearing or falling off even with structural vibrations or cracks, and by adhering stably even underwater.



【Financial News Yeoju=Shin Ji-min Reporter】Lee Jong-yong, CEO of Rinew System, explained on the 27th, "If existing waterproof materials adhere to concrete and harden, Turbo Seal remains flexible by adhering." This product withstands temperature changes from minus 40℃ to plus 60℃, and can endure a water pressure of 10 atmospheres and a pressure of 100m underground. Its viscosity reaches 2.5 to 5 million CPS, dozens of times that of honey, maintaining adhesion similar to fixed structures.

Rinew System's waterproof technology has been proven through over 200,000 construction cases domestically and internationally. In Korea, it has been applied to various structures such as Incheon International Airport Terminal 2, Gwacheon Line Subway, and SK Hynix Semiconductor Plant. In particular, the 1999 construction case of the National Folk Museum is cited as a representative case with no leakage to date.

Overseas, it has been applied to structures in 29 countries, including the Big Dig in Boston, USA, the San Francisco Subway, and the Toronto TTC in Canada. In the case of the Singapore MCE Highway, no leakage has occurred in the 7km section constructed in 2012, even after 13 years, leading to requests for repairs in adjacent sections that were not constructed.

The company is also engaged in a chemical recycling business that decomposes waste plastics and fibers chemically to revert them to raw materials. The flagship product 'GTR Sheet' is a resource-circulating composite waterproof sheet that can block leakage simply by attaching it, by combining gel-type waterproof material and high-strength sheets.

The CEO views waterproofing not as a simple repair process but as 'disaster safety technology.' Rinew System is blocking groundwater inflow into underground structures with its self-developed 'TWS Method.' The CEO emphasizes the public nature of waterproofing. He suggests, "Since there are complaints above ground, at least some effort is made, but there was little interest underground. Seoul extracts 14 million tons of groundwater annually," and proposes "institutional improvements such as mandatory external waterproofing, extension of defect warranty period, and prohibition of waterproof materials containing carcinogens."
