Parking Decks & Split Slab Construction

US Drainage Systems, LLC PercoDrain provides a necessary drainage layer between the wearing surface and the structural slab that unlike an aggregate layer will not require an increase of structural design strength. PercoDrain provides more drainage capacity than aggregate and has little to no increase of weight to the structure.  Therefore, the engineer does not have to increase the structural slab of column strength of the structure.
