Selection criteria for garden tiles

Not only the interior but also the homeowners are interested and focused, besides the choice of brick wall, floor tiles, the choice of garden tiles not only help clean but also help the house Your more impressive.

With buildings such as garden villas, the choice of garden tiles should pay attention to many factors. How to choose the bricks to highlight the work and how to arrange them must be impressive, harmonious in the color factors, size to honors the beauty of the whole works. Therefore, the choice of garden tiles should be based on the following criteria:

Depending on the size of the function, it is necessary to use bricks

Depending on the area of ​​†<†<functional need to pave the brick you make the decision to choose the right tile. You can also set individual large bricks with a step foot on the green grass floor also helps to make the garden more luxurious.

Ensure hardness

Normally, tile for garden is to create aisles, where people often have to pass, so first brick must ensure the hardness. If bricks are too soft, only after a short time of use will be prone to cracking, broken by the force in the process of moving people.

Not slippery

Since it is used to tile the outdoor area, garden tiles will not be able to withstand rain, which is very easy to slip. So for safety reasons, you should choose a high friction surface type. These are bricks of the surface, the surface is patterned floating.

No mold moss

Outdoor garden tiles are very easy to get rainwater. If the surface is bricks or made of materials such as terracotta, it will cause moss mold, slippery, dangerous, just unhygienic and aesthetic.

Quick drainage

In the days of heavy rain or when gardening will inevitably stand the status of brick stagnant water. Stagnant water will be the ideal environment for moss growth, insect pests, surface molds cause aesthetic... Therefore, the ability to drain water is also a factor that you need attention. When selecting tiles for the garden.

In conclusion, to make the synchronization, harmony from the outside, the selection of brick to paving the garden is very important. The exterior of the building is beautiful, clean and new, contributing to the architecture of the house.

Guide to choose wall tiles suitable for your home

Brick wall is an important factor to help improve the house, choosing the right type of wall tiles will make your home look more delicate and luxurious.

Currently, instead of choosing wall paint, most families choose to use wall tiles, clean, clean and easy to clean and also durable. But the choice of brick wall tiles with patterns, patterns to match the architecture as well as background color is not a simple thing. The article below will tell you how to choose wall tiles to help improve your home.

Brick quality inspection

When choosing the type of brick wall, people often pay attention to the pattern, texture, color, size, type of tile suitable for each room design in the house. You can check the quality of the bricks with the naked eye with the following criteria: standard shapes with angles, colors are similar. You should check the quality by breaking bricks, if the quality will not be crushed into small pieces, beat two bricks together to have a decisive sound, drop the brick from the top (about 1m) will not break; If the brick quality is the reverse.

If you are more specific, then you should soak a brick in the water for 24 hours, then if the brick 25% heavier than the dry brick, proved to be poor quality, will affect the work, ant of the house. The ability to adhere to brick mortar of poor quality will reduce, reduce the quality of construction of the house, both costly and ineffective.

How to choose brick type?

- Size: choose the size, brick size must be based on the area of ​​the house. Here is the size of the house and the brick size for your reference:

For homes, or rooms with an area less than or equal to 18m2, a tile size of 300 × 300 should be used.
For houses, or rooms with an area of ​​less than 36m2, tile tiles of 400 × 400, 300 × 600 should be used.
For homes, or rooms with an area of ​​over 36m2, it is recommended to use brick size about 500 × 500, 600 × 600, 600 × 900....

- However, you have to consider the area as well as the design of the house or each room to choose the most suitable brick size. Select the number of tiles based on the size of the house, the size of tiles you choose. If you choose the wrong area, it will make you feel uncomfortable seeing and deflecting the whole house.

Select the color brick wall

Choosing the color of the house as well as wall tiles must match the feng shui while highlighting the architecture of the house. Some note when choosing color tiles for you:

- Choose the color based on the tone of the interior of the house.

- If your house is a small town, less light, you should choose light tone, pattern, simple pattern. Limit dark colors to make the house darker and more crowded.

- Floor tiles, wall tiles, interior paint must have harmony of tone, should not choose the color too contrast. Decorative details on the brick should not be too prominent, simple details will make the house look more beautiful and reasonable.

Types of wall tiles

Currently, there are many types of wall tiles in the market with many types of external tiles, tiles, living room, kitchen, bedroom, bathroom, sanitation... In each position will have choice and different needs.

- Select exterior wall tiles (outside)

Exterior decorative bricks in locations such as: fences, gates, facades, ... you must use the type of bricks of good quality, high humidity and heat resistance, good humidity to match weather conditions outside.

- Select the wall tiles for the living room

You can choose from a wide variety of bricks of different sizes or sizes. Comfortable color contrast or gentle elegance according to the preferences of the owner. But most of the living room is where guests should be elegant and delicate with the light tonne, simple textures create a sense of closeness.

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.

Modeling and mapping in geological surveys

A geological survey is a systematic investigation into a given area for the purpose of creating a geological map or model for construction. Using techniques from the traditional survey, surveying trails and terrain, with intrusion methods, such as hand drill holes and drills, to use geophysical techniques and methods. Remote sensing, such as aerial photography and satellite imagery.

Geological survey report

Such surveys may be conducted by provincial or national geological survey organizations to maintain geological, inventory and geoscience knowledge for the benefit of the state. . Geological mapping usually describes the scope of the survey and the boundaries of geological units on topographic maps, along with information at points (such as orientation of the bed surface) and straight lines (such as intersection of faults with ground).

Maps and reports generated by geological survey organizations often aim for continuity and completeness of geography in the establishment of spatial models of near-surface rock units. The map may include cross sections to illustrate the three-dimensional representation. Geological and geophysical maps below the ground provide limited geological coverage (known, for example, from oil or gas drilling), maintained internally by oil companies. large mines and managers.

Several geological survey units have collaborated with them to include geological subsoil in their systematic surveys, for example, geological maps of sedimentary basins. A sub-surface map usually describes the three-dimensional shape of the geological surface by means of lines and cross sections. Computer-based models are increasingly being used to provide more comprehensive and flexible information storage capabilities in presentations.

Conclude

In a nutshell, it is understandable that, since exploratory surveys have been conducted, the reports are presented as drawings or models. Layers of sedimentary rocks with different characteristics will be clearly demonstrated to the geological survey drilling works, renovation of foundations.

Why should drill geological before construction

In addition to following the process, in order to meet the requirements, it is not easy at all, the work of calculating the stability of the items as well as the methods of construction. Much depends on the geological survey material. If the information is not complete or accurate information will lead to wrong design, lack of certainty, reduced safety of work. Can lead to many other dangerous consequences.

In the construction of the site, as well as our point of view, the geological survey is the basis for the design unit to propose solutions to design the foundation of some business buildings. but still ensure the technical requirements.

The concept of geological survey

Before exploring more about geological drilling as well as the importance of this stage, we need to understand this process. In our opinion, this is an important task to assess the conditional area. Perform by determining the hydrological conditions, mechanical properties of the soil layer, soil structure. For the purpose of designing the foundation, foundation. Major activities of this type are excavation, drilling, static, dynamic, static throw, horizontal compression.

When to conduct geological survey

Geotechnical drilling service Phan Tran said that according to the regulations of the Ministry of Construction, the construction works to be surveyed and the implementation process is specified in accordance with the law on state construction. Basically, construction works on weak soil and locations with complex conditions will have to do survey small or large drilling. In addition, the building has an area of ​​more than 250m2, buildings (from 3 floors up), important projects such as schools, hospitals, commercial centers, bridges and dams. This step is indispensable.

Reason for geological survey

Assess the safety of existing works, upgrades, renovations, designs, existing works as well as investigate the damage caused to the works.

Recognize changes in the future, and changes caused by the development, human impact, economic activity of the area are built... find solutions to problems or improve. It will happen in the build process and then.

Design, solution to build a reasonable platform and budget.

Whether the evaluation is appropriate for the work to be built or not.

Here we present the importance of geological drilling to survey. We hope you do not miss this step.

Experienced in soil treatment for ponds in Vietnam

Vietnam is an area where canals and ponds are very intricate, as the development of society, economics, science and population increases but the land area does not increase. To solve this problem, people fill ponds and ponds to build houses. The problem is that this will be a weak ground that needs to be treated before construction. Today, we introduce the method of pile foundation treatment.

One of the safeguards to build a foundation on a weak foundation is to use a foundation for housing. Pile foundation is becoming more and more popular, the number one choice is supposed to be when encountering this geological form.

Pile foundation is a type of nail that is placed above the pile to form pile groups linking the braces and the foundation to create a solid foundation. The basement is used in situations where there are complex terrain, weak soil such as ponds, lakes, plain land, weak areas.

Select the number of piles

Typically, when the design of the home does not include geological survey reports, it is extremely important to accurately calculate the number of piles to avoid wastage, which is directly related to the economic problems of the owner. .

The number of piles for each station depends on the load being transmitted to the top of the column, the depth of the foundation being buried, but the depth of burial is not related too much to determine the number of piles. To calculate the number of piles can be as follows:

Load floor, wall load, dynamic load due to total usage 1.2-1.5 tons / m2 x load capacity of column coefficient x 1.2x the number of floors.

For example: calculate the number of piles 200x200 with the capacity of 20t / pile head, for the column with the load area of ​​20m2 (5 * 4) => the number of piles = 1.2 * 20 * 1,2 * 1 = 28, 8 tons / 20 = 1.44 piles => select 3 piles in this case to ensure the nails work simultaneously in two directions.

Size

For 4 piles we use 1000 x 1000 x 700 and put steel ф12a150. The steel stake is associated with steel plates and steel beams forming a block.

Grout size 300 x 600, put steel on 3ф20, lower and ф8a150 for steel belt.

Note: However, for grade 4 houses, the use of pile foundation is relatively low due to high pile costs as well as unnecessary foundation.

Selection of pile presses

The load of the pile 200x200 = 20t is the pile head bearing static load 20t, the load on the pile is the dynamic load during construction, the dynamic load is usually 2-3 times static load, it is also loaded on the top of the pile. Therefore, the compression load at the pile head 200 * 200 is 20 * 2-20 * 3t = 40-60t.

When choosing the pile for base treatment, the force must be greater than 15% of the dynamic load => pile presses must be> = 75t.

When stacked, there will be a switchboard from the clock to the actual pressure, just watch the meter at your watch that is capable of monitoring your work.

That is the note when using pile foundation in soil treatment that we summarize for you readers. Hopefully the article can help you understand better to be able to understand and know what your unit is doing, is standard. Thank you for following the article.
