Sub Surface Highway Drainage. Sub grade may be damaged by sub soil water. Sub soil water as free water, when water table is high or it may come up by capillary action to the subgrade when water table is low. Sub-grade should be of self draining material so that it may pass off the percolation water that comes to it to remain dry and stable.
