cracking in concrete caused by drying shrinkage.
Polypropylene fibers are being used extensively throughout
the U.S.A. and Canada in all types of concrete construction,
and they have proven to be an effective method of controlling
unsightly and troublesome shrinkage cracking in concrete.
When accepted construction practices are used, Durafiber
polypropylene fibers can be used as a suitable and economical
alternative in most cases for wire mesh.

Durafiber 3/4" lengths are an ideal size for fast and thorough mixing.
You will find that Durafiber has excellent dispersion qualities in
all types of concrete mixes.
Durafiber absorbs energy - The multi-directional positioning of
assists in relieving the stress that is developed during shrinkage.
This energy is distributed to millions of fibers and will result in
a reduction of plastic and drying shrinkage cracking.
Depending on the application, one cubic yard of concrete containing
Durafiber can have in excess of 20,000,000 crack resistant fibers.
Precast Concrete - Durafiber is especially suited for use in precast
units because of its ability to mix quickly and thoroughly into the
There is no unnecessary time delay or extended mixing required. The
large number of fine fibers per cubic foot of concrete help assure
maximum protection to the unprotected edges, corners and surfaces of
Durafiber used at the recommended quantity per cubic yard of concrete
will reduce the permeability of most concrete. If there is an existing
moisture problem, it is always advisable to use a low water/cement
ratio concrete with Durafiber.
Durafiber will not rust or deteriorate.
If wire mesh is not properly located in the concrete floor, water may
migrate into the concrete. If wire mesh is touching or in close
to the ground, severe rusting of the wire mesh and deterioration of
the underside of the concrete floor could result.
