What is Wet Basement?

A wet basement is formed because of the presence of moisture, molds, or efflorescence in the basement structure. The moisture can enter the basement either from an outside source or from inside sources. The outside sources like improper drainage, flooding, or higher groundwater level can result in tRead more
A wet basement is formed because of the presence of moisture, molds, or efflorescence in the basement structure. The moisture can enter the basement either from an outside source or from inside sources.
The outside sources like improper drainage, flooding, or higher groundwater level can result in the penetration of moisture into the basement structure either through the foundation cracks or through the walls. The inside sources like humidity within the room, pipe leakage, etc would increase the moisture within the interior causing condensation of basement walls and floors.
Extreme cases of moisture and condensation in the basement structure can result in structural damage.
A wet basement can be prevented by keeping water in the surrounding move away from the structure. A proper drainage system, a floor drain, a good landscape grading can help attain this. The use of dehumidifiers, exhaust fans, correction of pipe leaks, etc can help to maintain basement moisture.

The concrete pressure on formwork can be calculated without measurement. However, I can see that you'd like to be sure about it with experimental verification.

Hi, Ballast types depend upon the traffic and spacing and size of ties. The following are the materials used as a substitute for ballast : Ballast is a base for rails that are made up of stone used to hold the railway track on its position when loading from the railway's impact on the railway track.Read more
Hi,
Ballast types depend upon the traffic and spacing and size of ties.
The following are the materials used as a substitute for ballast :
Ballast is a base for rails that are made up of stone used to hold the railway track on its position when loading from the railway’s impact on the railway track.
- Now it is instead of stone a cement concrete ballast is used. It has a long life and High durability.
- In ancient days, wood ballast was used.
- Steel sections are also used as a ballast for railways tracks.

Kuldeep Singh
For upward pressure calculation, you need the depth of the foundation. You see, upward soil pressure goes in increasing with increasing depth of the foundation because it takes into account the overburden soil. The method is already given in your attachment. Upward pressure = ρD + W Where: ρ: soil dRead more
For upward pressure calculation, you need the depth of the foundation. You see, upward soil pressure goes in increasing with increasing depth of the foundation because it takes into account the overburden soil. The method is already given in your attachment.
Upward pressure = ρD + W
Where: ρ: soil density, D: depth until the top face of the foundation, W: the weight of the foundation
It doesn’t require the knowledge of Safe bearing capacity. The upward pressure can be lesser than the SBC depending on the situation. If it is more than the foundation is unsafe.

It's not true. You're wrong. The colour of the civil engineer's helmet on site is white and not yellow. That is the convention.

The colour of the civil engineer’s helmet on site is white and not yellow. That is the convention.
The purpose is to differentiate the engineer from other professionals on site. Every other kind of professional has a different colour helmet on site. The yellow one is for labourers skilled and unskilled both. Giving yellow helmet to engineers is disrespect in a sense.
An engineer must always demand or arrange for a white helmet for himself on site.

Ballast can be substituted by any material which prevents settlement of the crossties, is prone to environmental conditions and is cheap to procure and transport.
A few substitute materials could be
- Sand (river sand) : With a low cohesion and water retention, and good strength sand is very good as a ballast substitute. If it were cheaper, ballast might never be used.
- Robo sand : robo sand is nothing but mechanically manufactured sand by crushing rocks. It works the same way.
- Gravel : Gravel is Midway between sand and ballast stones in terms of size of particles.
- Rock : If nothing else, but rock is cheap, rock crushed into suitable size stones can be used.

The dome-shaped circular temple has a maximum height of about 35 mtrs at its centre. The temple is famous for its fully blossomed lotus design by the Iranian architect, Fariborz Sahba and constructed by Flint and Neill, and has won many international awards of excellence for design, architecture and execution. The temple has 27 free-standing petals of marble arranged in clusters of three petals of different sizes on 9 directions/sides with a closed lotus-shaped high dome at the centre all of marble cladding. The entire circular hall under the dome is north-lighted with central airconditioning.
