Anyone has any idea how to prevent flood water from coming into the house from the sliding glass door?
Water level is about < 0.5 inch but the work required to clean up the house is tiresome.

@hutazi, this would be one of the solutions but might not looks good especially on the front entrance.
Some of my neighbours did like this because they had just a swing door (more practical for a small area where the water can enters), but with a sliding glass doors (3 panels glass doors is a headache).

@enduser/@enriquelee, when the whole taman is submerge in water, with proper drainage on my house itself it will not make any difference because the water level rose higher than the drain.
