Cast-in-place concrete or Cast-in-situ concrete is a technology of construction of buildings where walls and slabs of the buildings are cast at the site in formwork. [1] This differs from precast concrete technology where slabs are cast elsewhere and then brought to the construction site and assembled. [ 2 ]
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 ).
Concrete regrading & leveling – Repair and level concrete surfaces that have settled. Existing substrate redecorating and renovating – Alter the appearance of existing concrete or wood substrates through applying "thin stamped" or "thin stained" overlays, creating new textures, colors and designs. For use on commercial or resident pool deck ...
A finished tilt-up building. Tilt-up, tilt-slab or tilt-wall is a type of building and a construction technique using concrete.Though it is a cost-effective technique with a shorter completion time, [1] poor performance in earthquakes has mandated significant seismic retrofit requirements in older buildings.
In poured concrete foundations, cracks and pipe penetrations are the most common entry points for seepage. These openings can be sealed from the interior. Epoxies , which are strong adhesives, or urethanes can be pressure injected into the openings, thus penetrating the foundation through to the exterior and cutting off the path of the seepage.
For removable forms, once the concrete has been poured into formwork and has set (or cured), the formwork is struck or stripped to expose the finished concrete. The time between pouring and stripping depends on the job specifications, which include the cure required, and whether the form is supporting any weight; it is usually at least 24 hours ...
Pervious concrete and asphalt designed to reduce frost heave and spalling damage has been used successfully in Norway and New Hampshire. [19] Furthermore, experience suggests that preventive measures with rapid drainage below porous surfaces be taken in order to increase the rate of snow melt above ground.
It is virtually impossible to make a concrete wall waterproof, over the long run, so drainage is the key. There are draining membranes that can be applied to the outside of the basement that create channels for water against the basement wall to flow to the foundation drains. [16] Where drainage is inadequate, waterproofing may be needed.
