While most people refer to street defects as potholes, there are various types of street defects that are caused by different factors and may require different methods to correct.

Perma-Patch; A polymer enhanced high performance cold asphalt patch that works exceptionally well on Utilities applications

Perma-Patch bonds permanently to asphalt, concrete, steel, wood, and other hard surfaces. It bonds equally well to dry, damp, or wet surfaces. Use directly from bag; no mixing, heating, or special preparation needed.

All these characteristics makes it an ideal patching material for all utilities applications requiring patching, and especially when two different materials like concrete and asphalt meet.

Manhole - Broken Asphalt

Broken asphalt around a manhole may be caused by the freeze and thaw cycles during the winter.  It also may be caused by an underlying issue with the manhole structure.  In some cases, they shift and collapse from lack of water draining.  This type of patching may take longer than patching a pothole.

Manhole - Asphalt Cut and Patch

The manhole depicted here has had a structural defect or repair work performed, which resulted in the surrounding asphalt being cut out.  When repairing manhole issues, the asphalt is often cut out in a square or rectangular shape. 

Perma-Patch would be placed around the manhole and out to the cut edges of the existing asphalt.

Utility/Street Cut

A utility or street cut is a section of asphalt cut out in order to install/repair underground utility infrastructure and it is repaved after the work is complete.

A defect with a previously patched utility or street cut .Often these cuts will settle after being patched which causes a dip in the street.  

Sinkhole

A sinkhole can be a depression in the road or in some cases where the pavement has given way (as in this photo),  caused by water moving underground or as a result of a break in the sewer/water system. 

Sinkholes tend to be very deep and the street appears to have collapsed.  This defect may take much longer than a pothole to repair as there may be a defect in the underlying sewer/water lines which would need to be repaired prior to patching with asphalt.
