Compound waterproofing method of green roof using copper barrier sheet and recycled tire melting liquid waterproofing material that reinforced treatments are valve and glass fiber mesh.

알루미늄 판막과 유리섬유를 합지한 구리방근시트와 폐타이어 용융액상 도막방수재를 이용한 옥상녹화 복합방수공법

This is green roof bottom system which composed by aluminum valve and glass fiber together as major reinforcement, so the cooper sheet can have root proof, and using recycled tire gel-type membrane waterproofing system which dost not contains VOCs. The copper sheet reduce the plants' root growing, so it helpes to maintain the waterproofing layer and stability of root proofing. Gel type membrane waterproofing system can do waterproofing, stress dispersion, and reducing leakage expansion. So those two materials can help each other to make green roof bottom layer would have the stability and durability.
