 Thorma-Joint is the best choice for bridge expansion joints with
a total movement of two inches or less. Thorma-Joint is the original
asphaltic plug joint system and has been in use throughout the World
since 1982. It is this experience that enables DSA to provide the best
plug joint system on the market. Backed by a sales and technical team
with an unmatched level of experience, you can rest assured that you
will be receiving a top quality joint system and a superior level of
customer service and technical support.
Using BJ Super™, our specially formulated bridge joint binder
material, and thoroughly tested granite aggregate, Thorma-Joint is
engineered to withstand the abuse of today’s busy roads without
cracking, rutting or material loss. By maintaining its integrity and
remaining watertight, Thorma-Joint safeguards your investment by protecting
your bearing surfaces from moisture and debris allowing the structure
to move as it was designed.
Unlike other bridge joint types, Thorma-Joint is low cost, watertight,
smooth riding and requires no maintenance. Typically lasting the life
of the wearing course, it is truly an “install it and forget it” solution
for low movement applications.
