You came to the right source, we are known in the
industry for our packer variety and very competitive prices.
You have decided on the grout and got the right pump.
Now you move on to step three: Which packers or ports will you
use for your injection job? Packers come in many sizes and
shapes. Prices range from cents to dollars. But how do you
decide? Is more expensive always better - is plastic as
effective as metal and rubber?
Well, it all depends. The injection method and the
selected material will help you to determine the hardware. Are
your cracks actively leaking, are they dry, do you use epoxy or
do you inject polyurethane? How much pressure will be used,
how do you connect your grout line?
There are two primary categories of packers available.
Insertable packers (mechanical packers) and surface mounted
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
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 advantage in high volume
applications and it offers a superior connection which is
helpful for single operator injection and large applications.
Injection pressure is the keyword. To determine a
quality packer it must withstand high injection pressures
without leaking and moving out of it's drill hole. A snug fit and
solid connection are mandatory. Nobody likes packers to fail
at injection pressures of 1000psi and more. Now, realistically
speaking even the best packer may slightly leak at the
connection at extreme pressures. But there is the difference
between a drip and a gush.
Premium packers are made of metal and an
expandable rubber sleeve to minimize concrete spalls and
packer blow outs. A medium soft, 'made to stick' rubber that
evenly expands diameter while compressed provides the best
grip. Mechanical packers made of cheap plastic and a plastic
sleeve are at a disadvantage at high pressures, but may
suffice at lower-high volume injections. Always keep in mind,
a snug and reliable fit is essential for the safety of the technician
and the key factor for successful injection work.
The size of the packer selected depends on the
volume to be pumped, drill depth, injection pressures to be
applied as well as cosmetic and other considerations. Common
diameters are 1/4inch, 6mm, 3/8 inch, 8mm, 10mm, 1/2
inch,13mm, 5/8inch, 16mm, and sometimes 3/4 inch or even
larger. (In mining applications for example, packers can be
several feet long and several inches thick) For concrete
injection, typically the 1/2" and 5/8" packer seem to be the best
compromise in strength and size and can be called a standard.
The smaller 3/8" (10mm) types have been gaining in popularity
though. Long versions and extensions are also available. It is
good practise to keep the drill-holes rather smaller than larger
when selecting your packer size.
Design considerations such as location of an anti
return valve, ease of use etc. may be of concern.
We generally recommend mechanical type packers
for most jobs. Their design can cope with most demands found
at an injection job and the 'problem rate' is very low - a packer
for all conditions. If high product flow at lower pressures is
desired, the 5/8" button head packers achieve good results.
The 3/8 Hammer-In packer performs at low pressures in
excellent concrete. Precise round drill holes are important for
a snug fit.
Surface ports are commonly used for epoxy injection
at low injection pressures. They are glued to the concrete
surface. A spread out base with holes is recommended for
good adhesion. The grout line can then be attached with a
quick-connect system. Since most surface ports lack an anti
return valve, a seal cap is provided for use after injection.
We provide unique ports for specialty applications
such as a surface port with a zerk fitting to utilize single
component injection systems for small epoxy and polyurethane
jobs, the injection screw for the SealBoss Inject Tube System
2000 for cold joints and other specialty packers.
