Technology Overview. Rammed Aggregate Piers are a patented/proprietary ground improvement system that uses compacted aggregate to create stiff pier elements. The installation process modifies the soil surrounding the piers.
Foxfire, also sometimes called fairy fire, is the bioluminescence created by some species of fungi present in decaying wood. The bluish-green glow is attributed to luciferase, an oxidative enzyme, which emits light as it reacts with luciferin.
The standing pilot light, an auxiliary flame that ignites the burner, may be extinguished. This is frequently caused by a defective thermocouple, a device that shuts off gas if it senses no flame at the pilot. A bad thermocouple may shut down a good pilot, which in turn prevents the burner from igniting to heat water.
