A revetment in stream restoration, river engineering or coastal engineering is a facing of impact-resistant material (such as stone, concrete, sandbags, or wooden piles) applied to a bank or wall in order to absorb the energy of incoming water and protect it from erosion. River or coastal revetments are usually built to preserve the existing ...
Inside, the cracks were covered with narrow wooden battens. This palisade style was much more efficient to build than the traditional horizontal log cabin, since two half logs provided more surface area than one whole log and the vertical alignment meant a stronger structure for supporting loads like upper stories and roofs.
Walls and fortified wall structures were still built in the modern era. They did not, however, have the original purpose of being a structure able to resist a prolonged siege or bombardment. Modern examples of defensive walls include: Berlin's city wall from the 1730s to the 1860s was partially made of wood.
The walls of Benin are described as the world's second longest man-made structure, as well as the most extensive earthwork in the world, by the Guinness Book of Records, 1974.

Reinforced wood door. A typical exterior wooden door might be made out of two or more layers of oak planks. The grain of the wood would run vertically on the front layer and horizontally on the back, like a simple form of plywood.

This example of multiple structures includes a massive seawall and riprap revetment. A bulkhead is a retaining wall, such as a bulkhead within a ship or a watershed retaining wall. It may also be used in mines to contain flooding. Coastal bulkheads are most often referred to as seawalls, bulkheading, or riprap revetments.
