PRODUCT NAME:
ProPatch™
(Permanent High Performance Cold Patch)
DESCRIPTION:
ProPatch™ (Permanent High Performance Cold Patch) is a cutback asphalt product
that has been designed and developed using the best available materials. It is produced
with a specially tested and specified type of aggregate which is then mixed with a
thorough blend of our quality controlled bulk bituminous liquid. This mix can be applied
in sub-zero temperatures, will adhere in wet conditions, offers a permanent repair and can
be used from an uncovered stockpile for up to 24 months.
