It should not be provided at the locations of the door openings. The top level of DPC should match with the planned finished floor level. As DPC is cement concrete it should be cured with water for 7 days and after it has dried, a uniform layer of 85/25-grade bitumen should be applied over the surface.
Is DPC necessary for plinth beam? The foundation of a building is always in touch with moisture present in the soil and due to capillary action in the brickwork the moisture has the tendency to rise up in the building. To prevent this rise of water above the plinth level, DPC (Damp Proof Course) is provided.
Similarly, Which grade of concrete is used for DPC at plinth level? Solution(By Examveda Team)
Cement concrete of grade M15 (1:2:4) is used at plinth level.
How is DPC calculated?
quantity calculation of concrete for DPC of 50 square metre area. For the calculation of dry volume 33% volume is increased so we should multiply cofactor 1.33 in wet volume.
How DPC is done?
A damp-proof course (DPC) is a barrier through the structure designed to prevent moisture rising by capillary action such as through a phenomenon known as rising damp. Rising damp is the effect of water rising from the ground into property. The damp proof course may be horizontal or vertical.
What is the plinth level?
Plinth Level means the level of the floor of a building immediately above the surrounding ground.
How the DPC materials can be classified? DPC materials can be classified into 3 categories. The categories are flexible materials, semi rigid materials and rigid materials.
What is the most commonly used material for DPC? Rich Concrete is the most commonly used material in DPC. Usually, rich concrete in the proportion 1:2:4 that is painted with two relative coats of hot bitumen is used for the horizontal damp proof course.
When DPC is to be laid over large areas the material preferred is?
2. DPC Material for floors, roofs etc. For greater wall thickness or where DPC is to be laid over large areas such as floors, roofs, etc., the choice is limited to flexible materials that provide a lesser number of joints like mastic, asphalt, bitumen felts, plastic sheets, etc.
What are the types of DPC? Types of Damp Proofing Course
- Electro-Osmotic Damp Proof Course.
- Chemical Damp Proof Course.
- Pressure Grouting.
- Membrane Damp Proof Course.
- Integral Damp Proof Course.
- Cavity Wall Damp Proof Course.
What is the unit of DPC?
Damp proof course: Unit of measurement is sq. m and unit of m² payment is also sq. m.
What is DPC and DPM? DPC stands for damp proof course whilst DPM stands for damp proof membrane. A DPC is a material placed between courses of brickwork to stop the rise of water up the walls. The types of products used can include polythene materials, pitch polymer combinations or even materials such as slate.
Why is DPC needed?
The damp proof course prevents damp from the ground rising up the walls and damaging your property. Properties which have no appropriate damp protection layer or has a damaged damp course may be affected by excess moisture rising from the ground.
What’s DPC?
A damp proof course (DPC) is a form of damp proofing installed in a property to prevent rising damp and associated problems.
How do you choose a plinth level? The plinth height is in between 300mm – 450 mm from ground level. It is recommended that the minimum plinth height of 150 mm is adopted from the top of the road. Damp proof course (DPC) is laid on Plinth level. The purpose of applying DPC is to restrict the movement of moisture through walls and floors.
What is structural slab level?
What is Structural Slab Level? The term SSL stands for structural Slab level refers to the top surface level of the structural slab. This term is mostly used in the commercial and industrial markets. The term SSL is used when another finishing is going to be placed over the structural slab.
What is above plinth level?
Plinth height between 300 to 450 mm above the ground level is taken. Sill beam level from floor finishing level for 1100 mm and 600-650 mm for the drawing-room is adopted. While the height for sill 2130 mm (7′) in residential and 2316 mm (7’6″) in commercial in most of the cases.
How is DPC measured? Damp proof course about 25 mm thickness in cement concrete (1:1.5:3 or 1:2:4) combined with standard water proofing agent is applied evenly to the entire width of plinth level and is measured by multiplying the length of the D.P. course by its width in square metres.
What is the thickness of DPC Mcq?
Explanation: Cement concrete is used to provide DPC at plinth level. 38-50mm thickness of M15 (1:2:4) cement concrete is provided and it serves the purpose under normal conditions.
Which of the below is an example of DPC material? Solution(By Examveda Team)
Asphalt is an example of semi rigid material while plastic sheeting sheeting is flexible material.
What is provided at roof slab level over the DPC?
Tiles are provided at roof slab level over the DPC to reduce the dampness. The treatment involves the treatment of parapet and roof slab.
What is the purpose of a DPC? The function of a DPC is to prevent moisture or water passing from one part of the building to another. Damp proof courses should be designed in conjunction with flashings and damp proof membranes to ensure a continuous barrier.
Is a damp proof course necessary?
The reason why a damp proof course is important is because any excess moisture entering a building can lead to more serious property problems such as timber decay or structural damage. Properties that do not have an effective damp proof course are more prone to suffer from the following: Wet rot. Dry rot.
