Robotically Applied Polyurea Significantly Improves Quality of Traditional Field Applied Geotextile Liners
Unlike field spraying, application of polyurea in a controlled environment using automated robots assure a consistent mil thickness to meet job specs, improves performance quality and rapidly increases speed of installation.
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 of the and performance quality of the coating. In fact, a variety of factors – including wind, rain, humidity, temperature, operator fatigue, human error, and natural variability – has lead to a desire to have the coating
