While the far more common concrete foundation requires separate measures to ensure good soil drainage, the rubble trench foundation serves both foundation functions at once. To construct a rubble trench foundation a narrow trench is dug down below the frost line. The bottom of the trench would ideally be gently sloped to an outlet.

Slip forming, continuous poured, continuously formed, or slipform construction is a construction method in which concrete is placed into a form that may be in continuous motion horizontally, or incrementally raised vertically.

A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving ( see below ).
First the supports are built, then the pods are arranged in place, and finally the concrete is poured. This process may occur in three different approaches, however the basic method is the same in each: In situ: Formwork construction and pouring of concrete occur on site, then the slab is assembled (if required).

Small charges of concrete can be added while the base is being formed [6] to enlarge the base and improve the pile’s settlement performance. [3] Franki piles can be installed raked (or sloped) with a tilt of up to 4:1. [5] Raked Franki piles are always reinforced and are particularly suitable for structures subject to dynamic forces. [1]
A slurry wall is a civil engineering technique used to build reinforced concrete walls in areas of soft earth close to open water, or with a high groundwater table. [1] This technique is typically used to build diaphragm (water-blocking) walls surrounding tunnels and open cuts, and to lay foundations .
The most notable concrete structure from this period is the Pantheon in Rome. To mould this structure, temporary scaffolding and formwork or falsework was built in the future shape of the structure. These building techniques were not isolated to pouring concrete, but were and are widely used in masonry construction.
