As part of the efforts, the Taeha Trading Company under the Korean Kangan General Company mass-produces various kinds of "Taeha"-trademarked waterproof agents.

One of them is waterproof paint with superior low temperature bending and weather resistance, which has been proved effective in waterproofing the inside and outside of different structures like iron pipe.

Among them are also concrete-waterproof agent, which is well mixed with cement and has no chemical reaction on concrete bar, and bouncing waterproof putty to fill in cracks, which is highly resistant to heat and freezing.

According to Kim Un Dok, manager of the company, the waterproof agents are appreciated at home and abroad and have been applied to a number of construction projects in recent years.
