About RiserGard™
Microorganisms that cause wood decay thrive where wood is in contact with soil and moisture. This effect is seen in typical ground line decay. Depletion of oxygen in soil that comes into contact with a wooden structure severely restricts the activity of microorganisms that cause wood decay. Introduction of a suitable carbon source quickly depletes oxygen in soil and extends the time the soil environment is oxygen free. Adding a carbon source also changes the makeup of the microbial community around the wooden structure. The net result is a reduction in wood decay activity.
Using RiserGard™
Whenever soil is disturbed by excavation, oxygen is introduced into the subsurface. The presence of oxygen facilitates the action of wood decay fungi. Installing risers on a wood pole not only creates these conditions, it also compromises the pole surface when the riser is attached. RiserGard™ is the ideal product to deplete that oxygen and foster anaerobic conditions that inhibit wood decay. By placing RiserGard™ rods into the soil immediately adjacent to the riser (1 rod on each side of the riser) you can head off ground line decay problems in the pole in which you have just invested your time and effort. RiserGard™ is a Green product that uses no hazardous materials.
