  2. Geonets - Wikipedia

    en.wikipedia.org/wiki/Geonets

    A geonet is a geosynthetic material similar in structure to a geogrid, consisting of integrally connected parallel sets of ribs overlying similar sets at various angles for in-plane drainage of liquids or gases. Geonets are often laminated with geotextiles on one or both surfaces and are then referred to as drainage geocomposites. They are ...

  3. Hempcrete - Wikipedia

    en.wikipedia.org/wiki/Hempcrete

    Hempcrete is a construction building material that uses hemp shives, aggregate, water, and a type of binder to act as non-bearing walls, insulators, finishing plasters, and blocks. The material has low mechanical properties and low thermal conductivity, making it ideal for insulation material.

  4. Xbloc - Wikipedia

    en.wikipedia.org/wiki/Xbloc

    Also compared to older concrete armour units, as e.g. tetrapod which are normally placed in double layer as for rock protection, modern single layer armour units (like the Xbloc and Accropode), involve significantly less concrete. Therefore, less construction material (cement, gravel) is required, [2] reducing costs and also the carbon ...

  5. Culvert - Wikipedia

    en.wikipedia.org/wiki/Culvert

    Culverts can be constructed of a variety of materials including cast-in-place or precast concrete (reinforced or non-reinforced), galvanized steel, aluminum, or plastic (typically high-density polyethylene). Two or more materials may be combined to form composite structures. For example, open-bottom corrugated steel structures are often built ...

  6. Geocomposite - Wikipedia

    en.wikipedia.org/wiki/Geocomposite

    The third type within this area of drainage geocomposites is the category of prefabricated edge drains. These materials, typically 500 mm high by 20 to 30 mm wide are placed adjacent to a highway pavement, airfield pavement, or railroad right-of-way, for lateral drainage out of and away from the pavement section.

  7. Pervious concrete - Wikipedia

    en.wikipedia.org/wiki/Pervious_concrete

    A pervious concrete street in 2005. Pervious concrete (also called porous concrete, permeable concrete, no fines concrete and porous pavement) is a special type of concrete with a high porosity used for concrete flatwork applications that allows water from precipitation and other sources to pass directly through, thereby reducing the runoff from a site and allowing groundwater recharge.

  8. Expanded clay aggregate - Wikipedia

    en.wikipedia.org/wiki/Expanded_clay_aggregate

    Common uses are in concrete blocks, concrete slabs, geotechnical fillings, lightweight concrete, water treatment, hydroponics, aquaponics and hydroculture. LECA can be easily used for plant-growing substrate. LECA is a versatile material and is utilized in an increasing number of applications.

  9. Polymer concrete - Wikipedia

    en.wikipedia.org/wiki/Polymer_concrete

    The corrosion resistance and low permeability of polymer concrete allows it to be used in swimming pools, sewer structure applications, drainage channels, electrolytic cells for base metal recovery, and other structures that contain liquids or corrosive chemicals. It is especially suited to the construction and rehabilitation of manholes due to ...
