Notes on the construction of the foundation of the town house

Building a house is important and most important is the foundation process. Good foundation structure to get a solid house, especially in the city area. In the construction market, geological survey and foundation treatment services are available to address this need. Moreover, this is also a service to help builders obtain construction permits.

Detailed geological survey

This is the job of the contractor building, but you should also understand the geological survey process to grasp the foundation of the building. Regarding the construction unit and the foundation design, if it is not geologically clear, it may lead to failure of the nail to be strengthened or likely to lead to cracking when used in a relatively wasteful and difficult manner. towel. In the types of land for building houses, sandy soil is the best soil because it is very tight and strong, dries fast water, helps the organism to have a good living environment, has the use of self-cleaning land difficult to occur subsidence serious.

Design the foundation suitable for each land

Depending on the area of ​​the soil, the geological design of the foundation is appropriate for the results of geological survey drilling.

Deep foundation: Calculate the depth of the design, then bring the nails down to the right depth, used for high-load construction works, which should not be built in large groundwater areas for this type of foundation.

Basement: The depth of 1.2 to 3.5m is used for medium and small loads, built on good ground.

Difficulties in building design background

- Soil: poorly strength, the work on it is easy to tilt, subsidence, fall, water retention because of seepage of sewage.

- Clay: because the water is very poor, beautiful, not the habitat for oxygenated animals, automatically clean the soil. Building on this foundation will be susceptible to moldy, unclean, moldy growth ....

- Reference: ground types in construction

Note about reinforced concrete piles

For construction works in the area of ​​ponds and lakes, to ensure safety, it is necessary to drill reinforced concrete piles after geological drilling. One notion of general manicuring and concrete pile presses in particular is that drilling activities in the ground will easily affect adjacent land and buildings. It is recommended that the direction of the pile be pressed in such a way that the compressed soil is not directed to any building or structure around it.

Note about bamboo piles during construction

Bamboo piles usually have a length of 3m - 5m, density of about 25 piles / m2 pressed to the ground with. The purpose of stowing bamboo into the ground is to compact the foundation at the bottom of the building, increasing the strength of the foundation, forming a solid foundation for the foundation. However, bamboo piles are only used when the construction site has a high water level, otherwise it will not work. Too dry soil is not suitable for placing bamboo poles.

Note the selection of contractors, geological survey units prestigious

This day there are too many construction companies, before the construction you should refer to the unit with more prestige and experience, nor a valid price or not. Next, you should switch to geotechnical investigators and land processors and pulse tools, most of which is the foundation of the solution: to increase efficiency, increase bearing strength and load on the ground, ensure Structural foundation for stable construction.
