    – When a building has a very heavy, concentrated loads, such as in a high rise structure, bridge or water tank.

    Difference between Black Water and greywater:

    Black Water:

    • Blackwater is the best water from bathrooms and toilets that contains faecal matter and urine.
    • Waterproof kitchens and dishwashers are also considered Black Water due to the contamination of pathogens.
    • It is also referred to as she waits for groundwater and can carry diseases and bacteria both of which could be harmful.

    Treatment of blackwater:

    • The biological or chemical treatment and infection are required for treating Black Water.

    Greywater:

    • Greywater is the best water that comes from sinks, washing machines, bathtubs and showers.
    • Greywater contains a very low level of contamination and making it easier to treat and process.
    • Recycled greywater is commonly used in irrigation and constructed wetlands as long as no harmful chemicals are present.

    Treatment of Greywater

    • Greywater can be reused in cartoons with little or no treatment subsurface irrigation system to evenly spread water around in the garden.
    • This method is very safe for treated greywater.

    Thank you.

    The vertical movement in foundations is caused by :

    1. Either downwards movement of the wall or wall footing, when a wall footing sinks in soft soil.
    2. An up and down movement of the wall or wall footings such as when a wall is disturbed by frost in a freezing climate
    3. Expansive clay soils expand or shrink as their water content increases or decreases.

    Thank You.

    universal foundation is pile foundation.

    it is used at all location, so we call it universal foundation in simple way

    basically pile foundation use at

    • where bearing capacity of soil is low
    • where chances of differential settlement of foundation
    • where structural load is very high like bridge or skyskiper building
    • where black cotton soil is present
    • where bearing strata depth is very high
    • where structure need to resist excessive vibration (wind mill)
    • pile foundation we can use every where.

    There are two ways to set out foundation on a steep slope :- 1. Cut and fill refers to the process of leveling out the ground for the foundation by adding soil, removing it, or both.

    There are two ways to set out foundation on a steep slope :-

    1. Cut and fill refers to the process of leveling out the ground for the foundation by adding soil, removing it, or both. Soil may be brought in to fill the plot and make it level, or it can be dug (cut) from the slope and either trucked out or used to shore up retaining walls for the home. Depending on the grade, soil conditions, and other factors, cutting and filling can make construction multiple time more expensive than that for a home on a flat site.

    2. Using stilts is an alternative to cutting into the slope that involves using a crane to lift the home onto supporting wood or steel columns. This can be a much more cost-effective method than cut and fill and can also open up the realm of possibilities for home replacement such as building out water over trees or water.

    A continuous footing is the one which supports more than two columns. This footing is also called as strip footing and is analogous to the strip footing for wall. The loads from the individual columns are transferred either directly to the footing slab, or through a longitudinal beam running longitudinally when the loads are heavy.

    Jet grouting process:

    Jet grouting was first introduced by Pilots terraces S.A. in the year 2010 and in 2011, the first project using jet columns was constructed.

    Applications:

    • Soil capacity improvement
    • Settlement control
    • Reduction of soil permeability
    • Other environmental applications
    • Underpinning existing Foundation
    • Ground improvement
    • Lateral support excavations
    • Hydraulic barriers
    • Slope stabilization
    • Liquefaction control

    The treat grouting is one of the most demanding soil improvement technique and requires excellence in designing and execution engineers and involved specialist.

    The field test allows selecting the most effective execution parameters and verifies that the final product with its design properties.
