It was first conceived by Wright in the wake of the Depression in 1936 and later developed in response to a lack of low-cost housing and rising construction costs following ...
Moir produced a design for concrete machine-gun pillboxes. [15] Designed to be constructed from a system of interlocking precast concrete blocks, with a steel roof, around 1500 Moir pillboxes were eventually produced (with blocks cast at Richborough in Kent) and sent to the Western Front in 1918.
Permeable pavement surfaces may be composed of; pervious concrete, porous asphalt, paving stones, or interlocking pavers. [1] Unlike traditional impervious paving materials such as concrete and asphalt, permeable paving systems allow stormwater to percolate and infiltrate through the pavement and into the aggregate layers and/or soil below. In ...

A concrete block, also known as a cinder block in North American English, breeze block in British English, concrete masonry unit (CMU), or by various other terms, is a standard-size rectangular block used in building construction.
During World War I, Sir Ernest William Moir produced a design for concrete machine-gun pillboxes [5] constructed from a system of interlocking precast concrete blocks, with a steel roof. Around 1,500 Moir pillboxes were eventually produced (with blocks cast at Richborough in Kent) and sent to the Western Front in 1918. [6] [7]
