Sinwol tap water treatment which is located on Seoul city is water works facilitysupplying drinking water. There are several tens of filter beds in this facility, but crack and leakage are inprogress on concrete structure that is caused by using long. To repair this defect, works should be conducted without stopping of operatingthe facility considering the condition of water works. Furthermore, waterproofing material must not contain poisonous ingredients.To meet this condition, a test for about 40 kinds of chemical detection is takenwith polyurea resin, and then the material is approved to be used for water worksstructure based on the test result by the government.

Repairing is done in consecutive for all filter bedsstopping operating of each bed during working.

Polyurea resin is used for waterproofing of various underground structures inInchon International Airport opened 2001. For the waterproofing material which is used on the underground structure, saltresistance is necessarily required because this airport is built on reclaimed land.Polyurea resin is applied for this project being recognized its salt resistanceproperties and the advantage of easy application. The quantity used in this project is the biggest as unit project in the world, andstandard application manual of polyurea is provided during the working.

Polyurethane foam is applied for theprotection of polyurea layer when refill theunderground structure with soil, gravel andsand after waterproofing. PU foam is applied with the thickness of20~30mm because polyurea film can bedamaged by sharp edge of gravel and etc.during refilling work.

In this factory wastewater treatment facilityof KUKDO Chemical Co., Ltd. waterleakage from concrete structure is inprogress due to the using long time.Simultaneously, the corrosion of steelstructure which is located in bottom part ofthis facility forces indispensable repairing. For the repairing of this facility, two factorsdescribed hereunder are considered;- chemical resistance against strong

alkalinity waste water- short down time under the condition of

24 hrs operation factory To meet these requirement, polyurea ischosen as the most suitable material andapplied for repairing.
