Protection Board
**************************************************************************
NOTE: Always require protection material seperating
waterproofing from fill material. Delete protection
board option and require the polymeric grid option
for earth covered magazines or facilities with
routine ground water exposure
**************************************************************************
**************************************************************************
NOTE: NOTE: The fiberboard will not provide
protection after it becomes wet.
Bituminous-impregnated protection board must not be
used in contact with polyvinyl chloride (PVC), which
may be in composite membranes. Polystyrene is not
compatible with petroleum products. The membrane
and protection board must be compatible.
**************************************************************************
[Provide protection board that is compatible with the waterproofing
membrane. Use a minimum 13 mm 1/2 inch thick fir bituminous - impregnated
board, 25 mm 1 inch for polystyrene, 3 mm 1/8 inch thick for vertical and 6
mm 1/4 inch for horizontal premolded bituminious protection board as
recommended by the manufacturer]
[Three-dimentional, high impact resistant polymeric grid with woven
monofilament drainage fabric bonded to the grid.]
