Caissons
The word "caisson" is derived from the French word meaning "case". In civil engineering a caisson may be defined as a large watertight box used to excavations of foundations and the construction of substructures. It is an integral part of the structure. This box or caisson may be "open", without a bottom or may be excluded by air pressure, and the box becomes a pneumatic caisson. This was a development of the earlier cofferdam — a wall within which, after pumping out the water, it was possible to excavate and then build the base of the pier in the dry. The ordinary open caisson consists of a box with cross walls. Sometimes the caisson is constructed of reinforced concrete or a steel cylinder.
Say if its true or false. Use the following expressions: "That's right" or "That's true", "That's wrong" or "According to the text…".
The word "caisson" isn't of English origin.
In construction engineering a caisson is defined as a small watertight box applied to exclude water during the assembly work.
This box may be with or without a bottom.
If the box is inverted, the water may be excluded by water pump.
The common open caisson has usually a box with cross walls.
Say the facts proving the following statements.
1. In civil engineering caisson is used when ground is rich in water.
2. In caisson usage air pressure plays a very important role.

Floors
Basically, there are two kinds of floors for interiors: those that are an integral part of the structure (hardcore) and those that are applied after the structure is completed (floor finishes).
Hardcoreis a careful selection of hard, dense material such as broken brick or stone which is chemically stable. It can be strengthened by careful grading and compaction to form a firm foundation for the structure.
To avoid using more concrete than the required minimum, since concrete is expensive, the hardcore is often "dressed" (or finished) with a fine agent layer of 50 mm average thickness of cement/sand in a 1:2 mix. This can be levelled easily using the profile boards as a standard to receive the concrete. The thickness of concrete both for foundations and oversite can be measured by using timber pegs punched at intervals into the soil or blinding. These pegs should mark the required thickness so that when the mark is covered the thickness has been achieved.
A further economy effected quite often in modern house construction is the use of oversite concrete as the ground floor. If adopted this will require the introduction of a waterproof membrane.
Floor finishis designed at a later stage and is often changed in the course of a building's life. In areas of higher traffic harder surfaces may be used--for example, cut stone tiles of marble or granite, ceramic tile applied with epoxy adhesive to the substrate, or terrazzo, but these materials, beautiful as they are, tend to be too costly as surface applications. Floor finishes in commercial and institutional uses make considerable use of synthetic-fibre carpeting and vinyl composition tile.
Synthetic floor coverings are usually classified as resilient floors. The resilient flooring materials include linoleum, cork, and vinyl. Basically, resilient floor tiles are excellent flooring materials that are both economical and easily maintained. They can be given almost any appearance, which is a temptation that manufacturers are unable to resist. When the tiles are plain, in good colours or textures, they are very attractive and appropriate, but often they are made to imitate stone, brick, mosaic, or other materials, and the results are generally of a less satisfactory nature.
Quarry (unglazed) tile is a dense pressed fireclay product for floors, patios, and industrial installations in which great resistance to abrasion or acids is required. Ceramic and quarry tiles are made not only for such areas as bathrooms but are suitable for almost any space. Installation usually requires a cement bed over the existing subfloor, making this material difficult to use in existing buildings. Like other natural materials, quarry-tile floors possess a natural beauty and have the additional advantage of easy maintenance.
A small percentage of traditional construction still uses suspended timber ground floors with sleeper walls from the oversite supporting floor joists of rather small spans of about 1.5 to 2.0 m. Gaps are left to allow air circulation via air bricks in the outer walls to minimize the risk of dry rot in the timbers. This form of construction provides an added benefit of a space beneath the floor for installation of services.
