Liner
Liner has a number of different meanings, including a large ship and the fabric on the inside of clothing or material, which may also be referred to as a lining. In simple terms both liner and lining refer to a layer of different material that covers the inside surface of something. In general, but not always, a lining tends to be a fabric or some kind of thin material, whereas a liner might be considerable thicker (though this is not always the case and they are often interchangeable).
In construction, both liner and lining are used to describe a lining to the inside of a construction. For example a waterproof lining might be a thin sheet of plastic used on the inside of a swimming pool prior to a final render and tiling, whereas a form liner might be a rigid polystyrene piece of form work used to cast clean penetrations through concrete.
In infrastructure projects liners from concrete or metal might be used to repair or improve an existing pipeline without the need to remove it section by section (which means the pipe may not have to be taken out of service) the liner is driven to the inside of the existing pipe to effectively create a new unit. This process is normally normally called trenchless rehabilitation, which might be more efficient than replacement, as eliminates excavation of damaged sections is not required.
One very different interpretation of liner, perhaps more common in the US is as in a liner building. A liner building is normally a retail or business structure which is effectively built to hide an unsightly building or use of a building such as a service area or substation. It has some relation to what might be called an infill site or infill building which makes use of otherwise difficult to develop left over urban plots. This understanding may be more common as a planning as well as legal term, meaning a cover building which is normally shallow and located along a street adjacent to the unsightly activity that it hides. In some ways this interpretation relates to the other meanings in that it effectively acts as a lining to the urban fabric.
