| SANWA foam is flexible, readily compressible,
closed-cell polyethylene joint filler supplied in sheet form.
Strip and special size are available. The product is designed
for the use as an expansion joint filler in concrete, brick
and block work, isolation joints and hinge joints. These are
used as back up strips for elastromeric sealants. |

| SANWA foam is positioned to provide a surface
sealing slot of required dimensions when used as an expansion
or isolation joint filler in brick-work, to ensure that the
sealing slot is free from mortar dropping or slurry bridging.
Suitable adhesive may be used to position SANWAfoam sheet but
ensure not to contaminate the surfaces of the sealing slot with
adhesive. when SANWAfoam is used as a back up strips it used
to regulate the depth of the sealing slot and ensure the movement
of the joint sealant is not restricted by adhesion to the base
of the sealing cavity. The size of the back-up strip should
be greater than the joint width, and depressed sufficiently
to provide the required sealing slot dimensions. |
