ROBOTICALLY APPLIED POLYUREA
QUALITY OF TRADITIONAL FIELD
APPLIED GEOTEXTILE LINERS
Unlike field spraying, application of polyurea in a controlled environment using automated robots assures a consistent mil thickness to meet job specs,
improves performance quality, and rapidly increases speed
For coating contractors, the use of geotextile liners
sprayed with polyurea has shown tremendous promise for
applications on bare ground or a substrate that is expected
to shift, move, or crack. Together, this combination of
liner-plus-coating delivers a seamless, extremely durable,
monolithic surface that retains some flexibility to stretch
and move without being compromised.
The challenge, however, is that the application of these
polyurea spray coatings can be inconsistent when applied
in the field, leading to variability in the mil thickness and
performance quality of the coating. In fact, a variety of
factors—including wind, rain, humidity, temperature,
Through precise metering as well as control of the indoor
manufacturing environment, robots can apply thicker,
more consistent mils of coatings across the entire surface.
This dramatically improves the quality and reliability of
the liner, compared to those sprayed by hand in the field.
The pre-sprayed liners are delivered complete with texture
and can be rolled out and seamed together to complete
the job in a fraction of the time. The robot can spray to
virtually any mil thickness required and custom liner
sizes can also be factory ordered to meet the needs of any
project. The same material that is used to manufacture the
liner is also used to spray the seams together. The specially
formulated polyurea sets up and cures almost immediately
and the project can be returned to service in a fraction of
the time as before.
