Poly Haze

All to often a contractor, homeowner, manufacturer or re seller will contact our company to assess and define the reason a problem of polymeric haze exists on a paver application. All of em want to know what happened, why and who is responsible. This becomes challenging as the installer including DIY homeowners claim it was a bad product and for some reason the manufacturer and or re seller is expected to accept the burden. This gets really old. Now with this pre-determined attitude a barrier has been established without rhyme or reason, that even with my information and expertise may not be undone. This also gets old.

Chemical and organic binders in polymeric sands are easy to understand, as well the graded sand each contain. Activating polymeric sands are also a basic discipline to master. Did your contractor know the difference between the two and how each applies, consolidates and activates ? Did your contractor understand the variables involved including air and substrate temperatures, dew point/ humidity, sunlight or shade, wind speeds or the type of joint/paver being filled. 

Buying a bag of stuff, putting it down and watering it in does not constitute due diligence to the discipline needed to achieve a proper application which is the installers burden to provide. Even reading the directions twice means nothing when using a product such as polymeric sand, no matter the manufacturer or re seller. So please drop the "it's someone else's fault" pitch, I am not buying it.

So what now? After I gather enough information I can tell you exactly what happened and why,  then explaining your options including the possible re actions both good and bad. The stumbling point now becomes your acceptability of possible consequences in poly haze removals. 

While I understand poly haze is upsetting, it simply "is what it is" to me when entering the scene afterwards. I wish not give fault to any parties involved yet it is generally an installer error.

Edge Restraint

Edge Restraint systems are responsible for rotational interlock of a paver application. Through interlock, thousands of pavers together will act as one continuous surface. Edge restraint failure will result in shifting/creeping of pavers leaving open joints which will result in bed sand loss leading to possible rutting or settlement. 

The desired outcome of an Edge Restraint is that it stays stationary. Understanding the degree of lateral forces that will be exerted on the system is critical to determining what type to use. With the correct Edge Restraint system in hand accurate installation is critical to its success. Trying to save money on shorter spikes or less of them can cause a failure. And setting spikes into the ground will not hold, they must be driven into base material.

The most common type of edge restraints are made of black PVC and set in place with spikes driven into the base material. On straight runs rigid Edge Restraints are preferred and flexible is used on curve-linear applications. 

Hedberg Landscape and Masonry Supplies (3 Metro locations) provide quality Edge Restraint systems. I have yet to find comparable products at the big box stores. 

Replacing Edge Restraint systems begins with identifying the underlying issue and correcting it. Repairing the damage created by the failure will become more involved the longer the failure exists. If you feel this condition may exist on your paver application feel free to contact The Paver Doctor. We specialize in paver Repair-Restoration-Sealing.
