Category of property zoning that designates property to be used for industrial purposes.
Industry
Any particular type of productivity, manufacturing, enterprise, etc.
Inert

Inert gas
Inert gas is a non-reactive gas, which prevents oxidation by displacing air or oxygen so it is used as an oxygen shield during welding. Since oxidation is speeded up greatly by the heat of welding, the presence of oxygen would be damaging to the finished weld.
Infill development or housing
New construction in an already established area.
Infiltration
Air from the environment that penetrates crevices in a building. Penetration of water into the earth or through a structure.
Infiltration test
Testing a buried pipeline for leakage by sealing the empty line and checking to see if any water leaks into the system from another source.
Infinite

Elastomer plug, which can be inflated and is often used to seal off a portion of a pipeline that needs to be pressure tested.
