In addition to hand mixing in bags or buckets, many PUF systems can be applied with equipment known as sprayers or pumps. These plural dispensing units pump heated chemicals at high pressure to a gun which mixes and sprays out the foam. These chemical systems are usually very fast, rising and setting in seconds (as opposed to minutes with EFS). However, they do have some applications in adits, ground sealing, and pipeline work.
