Mechanical packers are typically used for polyurethane injection and high pressure epoxy injection. Since they are not glued to the surface, they work well in wet areas and with decayed 'problem' concrete.

Mechanical packers come with zerk fittings and button heads (slide fittings). The zerk type is more commonly used and is less costly. It easily connects and disconnects and works nicely with medium to high injection pressures. The button head type can be of an advantage in high volume applications and it offers a superior connection which is helpful for single operator injection or large applications. Injection pressure is the keyword. To determine a quality packer it must withstand high injection pressures without leaking and moving out of its drill hole.
