DSM SYSTEM retrofit of failed compression
seal expansion joints in metal-angle-edged parking deck joints.
Generally, it is
better to remove metal angles from the deck edge and repair the edges with
EMCRETE or a cementitious, structural
repair mortar. Where this is not
feasible, DSM SYSTEM can be installed into the metal angles. Before
installation, it is critical to sandblast or grind the faces of the metal
angles to clean, white metal. A quick solvent wipe precedes installation of
the EMSEAL-supplied epoxy to the substrates.
Application of EMSEAL supplied epoxy to substrates using a margin trowel.
Application of EMSEAL
supplied silicone sealant to face of DSM foam at join.
Joined piece of DSM foam
is pushed into the face of the already installed stick. The join between the
two sticks is held above the deck surface until the adjoining stick is
seated in the joint...
...the DSM foam on both
sides of the join is then eased into final position. This method
ensures a tight compression-fit between the joined faces.
Silicone bellows is
cleaned of excess epoxy.
Approx. 3/4-inch (20mm) deep silicone sealant band is injected between
face of DSM foam-and-bellows and the substrates (both sides).
Silicone sealant is
tooled at corner of substrate and silicone bellows to form finishing cove
bead.
DSM SYSTEM installation
is complete.
