What is damp proof course DPC method installation of construction

What is DPC method of DPC installation in construction

Damp proof course DPC generally applied at basement levels which restricts  the movement of moisture through walls and floor selection of materials for damp proof course and it is various method of application in building is disclosed


Damp proof course material DPC

An effective damp proofing materials should have the following properties and purpose of damp proof course

1. It should be strong and durable and should be capable of withstanding both dead as well as live load without damage
2. It should be impervious
3. It should be dimensionally  stable 

Damp proof course type of materials

1. Flexible material materials like bituminous  flats which maybe Hessian based or fiber/glass fiber based plastic plastic sheet polythene sheets ect
2. Semi rigid materials materials like mastic Asphalt or combination of material or layers
3. Rigid materials materials like first class brick stone slag cement concrete ect 

                                                                               

Damp proof course selection of building DPC

                                                                               

The choice of material to function as an effective damp proof course require a judicious selection. 

It depend upon the climate and autumn spare condition nature of structure and the situation where DPC is to be provided

The points to be kept in view while making selection of DPC material are briefly discussed below

                                                                               

Above ground level DPC damp proof course

                                                                                                        

For DPC above ground level with wall thickness generally not extending 40 cm any one of the type of materials mentioned about maybe used cement concrete is however commonly adopted materials for DPC at plinth level 38 to 50 mm thick layer of cement concrete m15 ratio 1:2:4 mix serves the the purpose under normal conditions

In case of dam and who made auto spare Reacher mix of concrete should be used the concrete is further made dance by adding waterproofing materials like pudlo lmpermo Waterlock ect.

In it is ingredients during the process of mixing it is used to apply two  coast of hot bituminous  over the third surface of the concrete DPC.

Damp proof course material for floor roofs etc.

For Greater well thickness or where DPC is to be laid our large areas such as floor roofs ect.

The choice is limited to flexible materials which provide laser number of joints like mastic Asphalt bituminous felts plastic sheets ect.

The felts when used should be properly bonded to the surface with bitumen and laid with joints like mastic asphalt , bitumen felts plastic sheets ect. 

DPC where differential thermal moments occur 

In parapet walls and other such station material like mastic Asphalt situations material like mastic Asphalt bitumen felts and metal copper or lead are recommended

It is important to ensure that the DPC material is flexible so as to avoid any damage or Pancha of the material due to differential thermal movement between the material of the roof and the parapet

DPC cavity wall

In cavity wall construction like 30 hour the door or Window should be bridged by taxable material like bitumen felt strips or lead ect 

Damp proof course installation in construction

1. DD PC Suite cover full thickness of wall excluding rendering 
2. The motor bed upon which the DPC is to be laid should be made level even and free from projection uneven base is likely to cause damage  DPC
3. When a horizontal DPC is to be continued up a vertical face a cement concrete fillet 75 mm in result should be provided at the junction Prior to the treatment.
4. HD PC should be placed in core 8 relation to the other DPC so as to ensure complete and continuous barrier to the passage of water from floor walls or roof 

I think now you may have come to know about DPC if you have any problem then comments thank you so much
