The Best Pump for Joint Filling

Posted by Jim Spiegel on Aug 21, 2019 9:15:41 AM

The Best Pump for Joint Filling

The Best Pump for Joint Filling

In this post, we'll profile the Alchemy-Spetec Joint Filling Machine, which is used with AP Joint Fill 800 and AP Fast Repair 850 for structural repair jobs.  This article covers a lot of technical territory in a few short paragraphs.  So, if it raises any questions for you, please call us at 404-618-0438.
 
Off-ratio product is probably the most prevalent issue with polyurea joint pumps.  This typically comes down to just a few possible scenarios.  Most commonly the material may be a bit too thick for the machine.  For instance, many suppliers market their pumps as "joint filling", but fail to specify product choices for the pump.  A small difference with the Alchemy-Spetec Joint Filling Machine (manufactured by US Saws) is the 1" throat from the bottom of the hopper leading to the rotary gear pumps.  Most suppliers are using 5/8" or 3/4" throat.    
 
Another common symptom you may run across with some pumps: Any time there is any build-up in the static mixer (which is common with material that sets in 30 seconds or less), there may also be back pressure put on the system, and the seals around the shaft for the sprocket/chain assembly may blow, and then you'll see material dripping from the shafts by the chain.  This is another tell-tale sign that the pump you are using is not pressure rated high enough.  And once a seal is compromised at all, the ratios go all over the place.  Concentric seals do much better with this. Also be careful with your flushing agent here.  If you're not using the Alchemy-Spetec Joint Filling Machine, ask your pump manufacturer what the seals are made of.  PTFE seals typically hold up to solvents better than Viton, for example.  A chewed up Viton seal caused by acetone flush can be a common cause of off-ratio product. 
 
The reason we chose the pump we have for our line is because US Saws has it best figured out.  Feel free to browse the US Saws link below for specifics on the machine...
 
One of the things we really like with this pump is that they have a unique configuration of the chain/sprockets which keeps more teeth of the sprocket engaged, and that prevents any skipping of the chain when back-pressure is encountered.  Also, the HDPE tanks are nice because you can see the levels of the material.  With the steel tanks of other pumps, often times the applicator will happen to look into the tanks only to realize that the last 100' of joint fill he put down is off-ratio.  It's much better to see this in real-time, all the time.  This pump also has the wide throat and PTFE seals.

Leak Mitigation of Dynamic Cracks in Concrete

Posted by Charlie Lerman on Jul 10, 2019 11:12:23 AM

 Leak Mitigation of Dynamic Cracks in Concrete

 Leak Mitigation of Dynamic Cracks in Concrete

Concrete will crack – that is a fact. When cracks appear, they are dynamic or static, and structural or non-structural. If the crack is static, non-structural, and does not leak, epoxies are great to restore design strength. However, since concrete constantly shrinks, expands, and often leaks, the use of a flexible polyurethane resin to permanently seal active leaks is the optimum choice to create a leak-free environment.

Water leaking through concrete is as old as concrete itself. Any leaking structure is problematic. These issues range from reduced lifespan to liability and lawsuits. This paper will discuss the mitigation of leaking structures to facilitate its coating. Often, these cracks are dynamic in nature. Static or structural repair of dynamic cracks will fail when the concrete needs to “move” again. Flexible polyurethane grouts can be used to mitigate water intrusion. This will extend the life of the structure and is a crucial step in surface preparation for most coatings.

Why Concrete Cracks

Concrete will crack - that is a fact. But to treat the crack, you need to understand the nature of cracking. There are four categories of cracks: static, dynamic, structural and non-structural.  A crack normally falls into two of the four categories. Just as the names imply, a static crack is non-moving, and a dynamic crack moves. Structural cracks place the integrity of the structure in jeopardy, while non-structural cracks can be eyesores and allow water infiltration. 

Static cracks are the result of a one-time event. This may be a thermal or shrinkage crack that formed while the concrete cured, or from a damaging event like a car hitting the concrete.  Typically, these structures do not move which is the driving force to why they are no longer used today.

Dynamic cracks expand and contract due to reoccurring force(s). The forces include, but are not limited to, freeze/thaw cycles, rapid thermal changes, loading of the concrete, and expansive soils. If the joint’s design was not adequate to deal with these forces, the concrete will often crack. “Cracking in concrete is affected by the long-term conditions to which the concrete element is subjected. In most cases, long-term exposure and long-term loading extend the magnitude of cracks, principally their width, in both reinforced and plain concrete." (ACI 22R-01 2001).

External forces are usually repetitive and cause the crack to expand and contract. These cracks are not a structural concern, but water infiltration through these cracks can be a serious problem.

Epoxy vs. Flexible Polyurethane

In spite of the best efforts of the architect, engineer and contractor, structures will sometimes move in unanticipated ways causing cracks to appear. Resin can be injected into the concrete to accomplish one of two purposes:

  1. Restore design strength
  2. Stop water leakage

If load bearing members such as walls, beams or columns are weakened, injection of high strength epoxies may be appropriate. However, more often than not, the concern with cracking is water infiltration. Epoxies are designed to be strong with little to no elongation, and chemically bond the concrete back together which is not appropriate for a dynamic, leaking crack. Epoxy will be stronger than the concrete and will cause the concrete to crack nearby. Lastly, the majority of epoxies are water intolerant and not suitable for waterproofing.

Crack / Joint Injection

Examination of the crack or joint after cleaning tells us where the crack goes and how wide it is. The surface should be cleaned mechanically. Loose debris or patches should be removed to reveal the crack. To maximize results, it is best to inject an actively leaking crack.

Injection should start from the lowest point of a vertical crack or the narrowest side of a horizontal crack. Injection holes should be drilled at a distance away from the crack that is equal to half the wall’s thickness (Example: If the wall is 8” thick, drill your hole 4” from the crack). This forms an isosceles right triangle when drilling at a 45 degree angle, and ideally intersects the crack or joint at its halfway point through the wall.

A low viscosity, flexible polyurethane grout should be injected.  Polyurethane grout will react with water to form a “custom gasket” that has three different bonds - adhesive, mechanical, and compressive. “The aim of all injection processes is to obtain uniform penetration of the resin and complete filling of the crack.” (Perkins 2003). Urethanes are very chemical resistant, but always check with the manufacturer about specific chemical resistances for a project.

Patience is important in resin injection work - slow is better. Always start injecting with the pump set at the lowest setting.  I like to say “If crack injection is not slow and painful, you are doing it wrong.”

Case Study: Vault Coating Failure

A below grade concrete precast vault was epoxy coated during a summer, the dry season, in the Pacific Northwest. The following winter coating failure was observed only at the joint.  There was also indication of water intrusion and rundown (see Photo 1).

Leak Mitigation of Dynamic Cracks in Concrete 1

Photo 1
Inspection of the vault lead to the belief the failure was caused be water intrusion through the precast joint. In 2012 the joint was injected with a flexible hydrophobic grout (Photo 2).

Leak Mitigation of Dynamic Cracks in Concrete 2

Photo 2
After a number of months of observation with no water intrusion the coating was repaired and is still in service till today with no defects.

Curtain Grouting

Curtain grouting is a method of installing a waterproofing membrane on the positive side of a below-grade structure without excavation. Curtain grouting is appropriate when there is spider web cracking or extensive cracking of the concrete.  It is not possible to address a large number of cracks in proximity with crack injection due to the number of injection holes needed.  Often, curtain grouting is easier than crack injection, but more material intensive.  Curtain grouting is an excellent fix because even if the concrete continues to crack, there will be no leaks as the water is no longer in contact with the structure.

Summary

A coating manufacturer once stated “It is estimated that 85%+ coating and lining failures are due to inadequate surface preparation.” Moisture mitigation is a large percentage of that and must be addressed.  For dynamic cracks, flexible polyurethanes are one of the best repair methods out there.
