This picture shows a piece of tack strip
that was removed from a badly contaminated house that had wall to wall
carpeting laid over glued down parquet flooring on concrete. The carpet was
completely ruined and discarded and some of the parquet was
removed revealing severe contamination on the concrete and under the
The wood in Section A was left for comparison with the relatively
uncontaminated flooring in Section C. The tack strip was also left in place, a
section of which is pictured below. One other point to notice is the white marks on the paquet flooring in Section A & C. The what marks are reflections of the strobe light on the camera use to make the picture from the spots of crystalized urea salt on the surface of the wood. There are no white spots in Section B because the urea salt is in down in the concrete.
Notice the stained flooring in Section B. Some of the discoloration is the glue to hold
the wood in place, but the dark areas are were the urine seeped between the boards.
Note the very dark area along the trim strip. This is a very heavily contaminated area.
Further the wood along the bottom of the wall was also very
badly contaminated. Repeated spraying of 1:30 OdorXit solution on the floor
and directly into the gap between the floor and the trim strip was necessary to
eliminate the odor here.
