Expansion Joint

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.

Uses

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 applications.

Available in the following sizes:

-       Thickness:  ½'' and 3/8''
-       Width:  48'' (4 feet)
-       Length:  5 ft. to 10 ft.

Caution:

Should not be used in conjunction with polysulfide, acrylic or other polymer-based joint sealants.
