    en.wikipedia.org/wiki/Permeable_paving

    Permeable paving surfaces are made of either a porous material that enables stormwater to flow through it or nonporous blocks spaced so that water can flow between the gaps. Permeable paving can also include a variety of surfacing techniques for roads, parking lots, and pedestrian walkways.

    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.

    CCS provides geomembrane liner protection, while creating stable soil, berms and slopes, for non-slip protection and durable impoundment of liquids and waste. [39] Infill treatment depends on the contained materials: concrete for ponds and reservoirs; gravel for landfill drainage and leachates , vegetated infill for landscape rehabilitation.

  5. Pavers (flooring) - Wikipedia

    en.wikipedia.org/wiki/Pavers_(flooring)

    Pavers manufactured from concrete go well with flag, brick and concrete walkways or patios. Concrete pavers may be used where winter temperatures dip below freezing. They are available in hole, x-shape, y-shape, pentagon, polygon and fan styles. An interlocking concrete paver, also known as a segmental paver, is a type of paver.

  6. Types of concrete - Wikipedia

    en.wikipedia.org/wiki/Types_of_concrete

    Pervious concrete, used in permeable paving, contains a network of holes or voids, to allow air or water to move through the concrete This allows water to drain naturally through it, and can both remove the normal surface-water drainage infrastructure, and allow replenishment of groundwater when conventional concrete does not.

  7. Tetrapod (structure) - Wikipedia

    en.wikipedia.org/wiki/Tetrapod_(structure)

    A tetrapod is a form of wave-dissipating concrete block used to prevent erosion caused by weather and longshore drift, primarily to enforce coastal structures such as seawalls and breakwaters. Tetrapods are made of concrete , and use a tetrahedral shape to dissipate the force of incoming waves by allowing water to flow around rather than ...
