Asphalt Under Seal is hot asphalt pumped beneath the surface of the road that fills cavities thereby forming a waterproof barrier.

Asphalt undersealing provides an economical means of salvaging deteriorating concrete slabs. The hot asphalt pumped beneath the surface of the concrete flows under the slab and fills the cavities forming a support underneath the slab, thus reducing the amount of defection. Undersealing is appropriate for filling voids of a 3" average depth of less. When the undersealing is finished a uniform support is reestablished for the pavement. The asphalt applied has sought out the planes in the base and filled those planes. Extensive voids of 6" or more that exist under the slabs should be concrete grouted (mudjacked) and then undersealed.
Asphalt underseal is a specially prepared asphalt with a very high melt temperature, much higher than any temperature of normal environmental conditions. During the summer it will not melt or bleed to the surface causing a tracking problem. Underseal is pumped under the concrete slabs, using specialized equipment, at high pressure and an application temperature of 400-425 degrees Fahrenheit.
Asphalt undersealing prolongs the life of the concrete slabs. In many cases slabs not broken into more than four sections can be salvaged. This process can prevent the costly replacement of the concrete slabs.
This process is appropriate for any concrete pavements showing signs of developing voids, deflections, shifting, and pumping at the base under loads, mud stains at joints, hollow sounds and breakage (especially at the joints).
