Welcome to the webpage of Denich soil engineering Co.,Ltd. We are pleased to present the soil test, soil boring test and recommentdation about foundation design by senior civil engineer teams with more than 10 years experience.
Soil Test
Soil Test and Soil Boring Test
Soil Boring Test
The structures will be stability and safty, must be supported by indissoluble foundation
and also foundation design should be safe enough. Soil test and soil boring test is very important. The enables engineer to design a safty foundation by foundation engineering method and construction cost savings. Normally the price of soil boring test should be between 0.1 – 0.5 % of the total construction cost. Scope and details of soil boring test depends on the qualities of the project and soil condition. Civil Engineer must be assignment the details of soil boring test so that to have the data essential for analysis and design.
Sub soil conditions in various areas of thailand may have a variance so that the area is
different from the general area such as very loose sand, soft clay layer or depth of soil is strength and high variability, etc. This could be the cause of the failure of the foundation that causing unpredictable damage. Therefore the good project owner should focus on soil test for designing various buildings is circumspect and invalid by engineering method.

Soil Test
For a small sum you can protect, possibly, the largest investment of your life. Without
the right foundations, buildings can move and walls can crack. Why risk the expense for the cost of a soil test? Problems can be discovered prior to purchase or building. Being aware of any problems will enable you to determine future costs and help you to make vital decisions about the suitability of the land for building. This is a better alternative to finding problems after purchase of land or after building has commenced.
About Soil Test
A Drill Rig and other equipment are used to collect information and samples at various
levels on the site. Samples are taken to the laboratory for testing. A detailed report and summary of data is prepared. This is used by the engineer to design the foundations in accordance with Australian Standards. This design will match the site conditions, give you peace of mind yet will reduce the risk of over design thus saving you money.
More about Soil Test
Soil Test is an essential part of foundation design. Foundations are vital to the
integrity of every structure being the interface with the soil or rock below. Soil has a variety of properties which can vary from place to place and from layer to layer even within the limits of the proposed structure. At times soil characteristics can change considerably within a small area. Weather, climatic changes, and site management can, in the future, affect the bearing qualities of the soil. Putting it simply, if the foundations are not designed to the carrying capacity of the soils then they will fail and so will the building.
Important design considerations are bearing capacity and settlement. Obviously the
foundations must be able to support the considerable weight of the building. The soil or rock below must then bear the entire weight. Settlement may occur at different rates in different sections of the foundations. Other considerations include the ability of clay to shrink and swell with changes in moisture, eg from climatic changes, penetration of surface water or the effect of vegetation absorbing water.
Investigation of the site is limited due to economic and time constraints. A soil
investigation should always be used as a guide only, to give a general indication of sub surface strata, its approximate surface movement and its capacity to bear the proposed construction for the site. The design engineer should relate this report to the specific needs of the construction proposed for this site and if further information is required, should treat this report as preliminary and request a more in depth investigation. This report is based on site information as at the time of investigation. If after excavation of the site footings, the soil profile is significantly different to that indicated on the attached borelogs, or if the building is situated in a different location to that marked on the site sketch or if any material change has occurred to the site, this report will become void. This office is to be notified of such occurrences, so further investigation can be carried out.
A soil test and report are necessary to meet local authority requirements for building
