Briefly explain the difference between the end bearing piles and the friction piles?

4. End-bearing piles. Typical end-bearing piles aredriven through very soft soil, such as a loose silt-bearingstratum underlain by compressible strata. Rememberthis factor when determining the load the piles cansupport safely.5. Friction piles. When a pile is driven into soil offairly uniform consistency and the tip is not seated in ahard layer, the load-carrying capacity of the pile isdeveloped by skin friction. The load is transferred to theadjoining soil by friction between the pile and thesurrounding soil. The load is transferred downward andlaterally to the soil


What is the difference between Expansion and construction joint?

A construction joint is required to allow the structure to be built. Say there is an existing structure in the way of a wall. Part of the wall is built, then later the existing bit is removed, and the rest of the wall constructed. The place where the first and second parts of the wall meet is a construction joint. This kind of joint is usually built so that no movement is allowed. An expansion joint is one that allows movement between the two elements. There will be a comparitely soft material, such as rubber, asphalt or impregnated board placed between the parts. The latest innovation has lead to use non bituminous filler boards like polymer based HD100 board. It is also known as micro cellular filler boards. (More details about filler boards you have to visit hd100.in or kampun.com from there in-depth product knowledge available.) If it is concrete construction, any reinforcing bars will be arranged to allow movement. In most cases, if movement was prevented, the structure would crack or buckle. The joint allows controlled movement.


Where do you normally use a reinforced wide strip concrete foundation?

A reinforced wide strip concrete foundation is used if the soil is soft or is of a low bearing capacity. This would not work for heavy or clumpy soil.


Where can one find a dwg viewer as a free download?

One can find a DWG viewer to download for free from these sources: CNET, Tucows, Softpedia, Brothersoft, Pima, Bentley, Up Download, Find My Soft, to name a few.


What is Cement sand silt clay mortar mix?

mortar mix may be used as a strengthen agent for the available soft soils, it will increase shear strength, but in the same time bonding with aggregate will be decrease. it may consider as a soil stabilization method if cement added as 10% by weight of the sand silty clay. it will work good.
