Project: Dam repairs, Korea Designer: KEPCO (Korean Energy and Power Corporation).
Gemite product: Gem-Crete HDO
Objective: repair deteriorated concrete of the intake areas, spillways and piers of several dams – Geosan, Chuongju and others. The freeze thaw damage of poorly compacted areas were repaired using a high performance fibre cement composite – Gem-Crete HDO. The material selected was extensively tested for this application by the U.S. Army Corps of Engineers. It also obtained a special “high tech” certificate in Korea. The thickness of the repairs varied from 1 cm to 10 cm in depth. The material was hand applied after extensive and thorough surface preparation.
