To ensure the stability and longevity of a house, its foundation must be designed based on a variety of factors. Technical and geological surveys, information about seismic activity, preliminary data about the structure’s purpose and technical characteristics, as well as construction loads and environmental regulations, should all be taken into consideration.
Constructing a house foundation requires significant experience and expertise. Pile-screw and pile foundations can be used to support structures on complex terrain and transfer substantial vertical loads. Pile-screw foundations offer benefits such as low mechanization and reduced vibration, but are limited in length (10m) and diameter (1.2m). To build longer or wider screw piles, static load testing is necessary.
Correct placement of piles requires thorough technical investigations and calculations to ensure proper bearing capacity. The selection and installation of pile foundations, including screw pile foundations, is critical for the stability and safety of the structure being built. Therefore, this work must be performed with great care and according to industry best practices.
Typically, foundation installation begins with excavation and the removal of any water from the pit. Layers of geotextiles, sand, and crushed stone are then placed at the bottom of the pit, with the density and thickness of each layer depending on the bearing capacity of the soil and the calculated load the foundation will support. The type of foundation used, whether a strip or column foundation, is determined by the construction documentation.
After preparing the base, the next step is to install reinforcing cages and formwork. Reinforcement is essential to withstand tensile forces, as concrete performs poorly under tension. The reinforcement process involves processing, distributing, and installing the fittings. The formwork provides the necessary geometric dimensions for reinforced concrete construction and can be made of wood, metal, or a combination of both.
Next, the concrete work is carried out by pouring the previously prepared mixture in the designated areas. The mixture consists of a binder (cement), aggregates (sand, gravel, and gravel), and water. The concrete is either transported to the location by concrete trucks or mixed on site. It is then poured using concrete pumps with a bucket or directly from a concrete truck.
After seven days, the form is removed and the concrete is waterproofed and backfilled with soil up to the design mark level. Proper execution of all technical operations during the concrete work is crucial to ensure the longevity of the structure.
