Site investigation or Subsoil discoveries are done with the help of acquiring the information about subsurface conditions at the site wished-for construction. Soil discoveries consist of being responsible for the profile of the natural soil residues at the site, taking the soil tasters, and defining the engineering properties of soils using laboratory tests as well as on-site testing methods. In fact, there are many soil investigation companies in Dubai that will assist you to get top-notch soil investigation, soil laboratory testing and soil analysis services.

According to Soil Building Systems Inc., Sawdust shouldn’t be used as a soil amendment as its decomposition is very slow and will rapidly deplete existing nitrogen sources that may be in the existing soil. It has small particle size, which leads to poor aeration in the soil. On complete decomposition, cotton burrs are a great and powerful supply of nutrients and nitrogen. They also break-up tight clay based soils, improving moisture retention in sandy soils, and encouraging mycorrhizal interaction within root systems. Manure can be a great source of nitrogen and nutrients, if fully composted. But, its over-use can contribute to extreme levels of phosphorus and potassium, which can be harmful to the environment. Any consistently textured mulch should be satisfactory and will provide an adequate cushion for playgrounds.

Soil An important product of Weathering.

Soil testing provides a number of advantages, including determining the type of foundation required, avoiding resting foundations on poor soil or at insufficient depth, identifying corrosive soil, determining the possibility of soil liquefaction after an earthquake, and so on.
