Mr Kwong ask me to do the green roof experiment again,but this time is using a new Geo-textile from zinco which is from Germany.This matetrial has very small hole and gaps compared to the one i eariler used and it is much thicker.The result came out in much different time and as Mr Kwong is on leave,i mean while have to wait for him to be back to work.
