Mesh Water Guide construction method

It is a construction method which leads the crack accompanied by leakage of water, etc. to a drain without blockading a water way in a line along a leakage-of-water part.
There is comparatively much leakage, and especially when there is mainly no margin in an internal void cross section, It is effective at the case where leakage of water has occurred in the line along construction joint or cracks.
