    Differential settlement in foundation:

    Usually, due to poor compaction, lower bearing capacity of the soil, high depth of hard strata, various changes in water content in soil are the basic reason behind the differential settlement of soil.

    Apart from that, trees & vegetation is not good for foundation safety.

    Soil consolidation is the main reason for differential settlement of the foundation.

    Foundation push piers & foundation underpinning also harms the foundation, which leads to a differential settlement.

    Thank you.

    It is necessary to check the nature of the soil before you build your dream home. The ground where you are wanting to build your dream home, it is necessary to check the soil nature of it before starting construction work.

    Soil testing is first done to test the bearing capacity of the soil. The physical and chemical configuration of the soil is checked during this process. The soil must be able to withstand the load of the structure. The nature of soil decides the bearing limit as well as guarantees to decide the structural adjustment. The nature of soil relies on different factors, for example, climate, environmental change and for as far back as years the land was sent for what reason and what was there before.

    The length and depth of the footing are decided during the foundation relying on the nature of the soil. The water level of the soil can only be resolved from soil testing. In light of the soil testing results, the nature of the material can be chosen. For instance, because of dampness the zone is lead to corrosion, at that point it is essential to pick just corrosion safe TMT Bars for the construction.

    A soil test is a very significant step in construction before it starts. If the soil testing isn’t done, at that point the structure will be presented to various failures and the final result could be lethal.

    Types of Soil Testing for Construction

    Gravity Test

    Moisture Test

    Atterberg Limits Test

    • Liquid Limit
    • Plastic Limit
    • Shrinkage Limit

    Dry Density Test

    • Core Cutter Method
    • Sand Replacement Method

    Proctor’s Compaction Test

    Purpose of California bearing ratio test:

    1. The main purpose of the California bearing ratio test is the measurement of a soil resistance penetration before reaching its highest ultimate value of a shearing
    2. Basically, 2 California bearing ratio value is designed as a ratio in % of range 0 to 100.
    3. The important operation of conducting the California bearing ratio test are same of variations of various soil conditions and various type of construction.
    4. California bearing ratio test is used for the evaluation of subgrade strength of road and pavement
    5. California bearing ratio value used as an index of soil strength and its bearing capacity
    6. The results obtained from the CBR test are used with the Imperial curves for the determination of the thickness of pavement and various component layers of pavement.

    Potential Groundwater Impacts of Dewatering

    ·        Contamination

    Dewatering can cause the advancement of hydraulic gradients that are additionally fundamental for drawing out water towards wells. Dewatering close to a site with a background marked by contamination in groundwater can bring out hydraulic gradients that can convey the dirtied groundwater towards the dewatering framework and cause contamination. By and large, polluted water requires filtration. To evade this issue, the best technique is to introduce screen dividers and vertically separate regions utilizing bentonite seals.

    ·        Geotechnical Damage

    Dewatering can make the ground lose coherence; the result leads to ground settling. If the ground settling is vast, it can harm close by building and structures. When groundwater is removed from the soil, it makes the soil pack and squeeze. It can likewise also caused by small soil & shallow grounds being removed with the groundwater through well.

    This effect can be diminished by a better plan and the utilization of good filtration and groundwater treatment that keep the particles from being separated.

    ·        Impacts on Water Features

    Things that depend on the water like rivers, lakes, and springs have a cozy relationship with groundwater and are, in this way, influenced by dewatering and groundwater control by prohibition. It is essential to keep in mind that groundwater and water-dependent things have eco-systems and fill in as territories. An unfriendly impact of these water bodies will have a huge -ve effect on the earth.

    ·        Water Resource Depletion

    When groundwater is removed for longer periods and in huge amounts for personal or commercial use, it can conceivably bring down groundwater levels and reduce yields. This exhaustion brings about a decrease in significant water assets for other people. An answer to this issue can be an artificial recharge method that infuses release from siphon water back in the ground.

    Conclusion

    It is crucial to perceive and decrease the effects of dewatering and groundwater control on the earth as dependable residents of the world. We should embrace great construction dewatering treatment system design, examination strategies, and better groundwater remediation innovation to alleviate these issues before it is past the point of no return.

    Biological oxygen demand(BOD):

    Biological oxygen demand is one of the clinical procedures which is used to determine the amount of dissolved oxygen which is needed by aerobic biological organisms in a body of water to director organic material is present in given water samples and certain temperature for a specific period.

    Biological oxygen demand and chemical oxygen demand are different processes.

    To assess the quantity of surface water for the biological oxygen demand test and other purposes then it is important to understand the characteristics of dissolved oxygen content in water and wastewater.
