Where it fits
A flexible tow-behind Thermo-Lay patcher for crews that share trucks.
The trailer format is the flexible Thermo-Lay choice when a crew wants permanent patching capability but does not need a dedicated patching truck.
It attaches quickly to a variety of truck chassis, stores in a smaller yard footprint, and includes onboard hydraulic power and generator support so the tow vehicle does not need patching-system connections beyond brake and signal lights.
For municipalities and contractors that share tow vehicles across departments, a trailer can be the cleanest path into heated asphalt patching.
