Asphalt and sandbag revetment with a geotextile filter. 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.
Stamped concrete in various patterns, highlighted with acid stain. Decorative concrete is the use of concrete as not simply a utilitarian medium for construction but as an aesthetic enhancement to a structure, while still serving its function as an integral part of the building itself such as floors, walls, driveways, and patios.
Comparison of a ha-ha (top) and a regular wall (bottom). Both walls prevent access, but one does not block the view looking outward. A ha-ha (French: hâ-hâ [a a] ⓘ or saut de loup [so dÉ™ lu] ⓘ), also known as a sunk fence, blind fence, ditch and fence, deer wall, or foss, is a recessed landscape design element that creates a vertical barrier (particularly on one side) while preserving ...
Ecobricks are plastic drinking bottles packed with non-biodegradable waste to make a reusable building block. Structure in North Wales, UK composed of cob and ecobricks. This project symbolizes plastic sequestration, net-zero construction, as well as collaboration within the community.
Old concrete sleepers can be used for things like retaining walls, else they might be crushed to recycle gravel and the steel reinforcing. [ 9 ] Special sleepers may be necessary on extremely sharp curves, such as the new triangle at Newmarket, New Zealand on the 1,067 mm ( 3 ft 6 in ) gauge of radius 95 m (312 ft).
Some of the early designs were of interlocking and self-aligning bottles. The idea derived from a belief that the need for mortar would add complexity and expense to the bottle wall's intended simplicity and affordability. Some designs proved to be effective building materials, but too heavy and slow-forming to be economically produced.
The most common materials used in modern greenhouses for walls and roofs are rigid plastic made of polycarbonate, plastic film made of polyethylene, or glass panes. [1] When the inside of a greenhouse is exposed to sunlight, the temperature increases, providing a sheltered environment for plants to grow even in cold weather.
Retaining walls are relatively rigid walls used for supporting soil laterally so that it can be retained at different levels on the two sides. Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to (typically a steep, near-vertical or vertical slope).
