The WLF Expansion Joint is one of the best Expansion Joint
products in the world. This product is an asphalt saturated
fiberboard that has been developed and tested as per standard
methods of testing performed expansion joint fillers for concrete
construction (non-extruding and resilient types) to meet the
specification of ASTM D 1751.
This asphalt impregnated fibre expansion filler is composed of
tough, resilient, cellulose fibres securely bonded together with a
uniform impregnation of bituminous binder and performed into strips
or sheets. The material is strong but lightweight; cuts and
handles easily; resists breakage. It will not extrude from
the joint under normal compression and service temperatures, and
does not embrittle in cold weather. Installation is easy. It
will not twist, break or deform with ordinary handling. It
cuts cleanly, places readily, stays strong and sound through many
years of repeated expansion/contraction cycles.
This is a general, multi-purpose filler for expansion joints in
all types of heavy concrete construction. It is specifically
engineered for commercial, industrial and public works
Available in the following sizes:
- Thickness: ½'' and
- Width: 48'' (4
