Vertical damp-proof course. Polypropylene DPC 1.5mm. Expanded polystyrene 0.038W/mK bonded. Standard 2400mm lengths. Profile illustrated suits standard brickwork and blockwork of up to 110mm thickness. Other profiles available for all sizes. Preformed DPC available in many profiles. Very severe rating with checked reveal using formatted version. Answer: DPC or damp proof course is generally 40~50mm thick. However if there is any uneveness of the brick/ Stone masonry beneath, it is corrected in the DPC. Hence the thickness may not be uniform. Damp proof course is meant to avoid transfer of moisture from the foundation to the walls above.

May 02, 2017 · TYPES OF DAMP PROOFING COURSE AND ITS THICKNESS USED. May 2, 2017 / Abbie John. Damp proofing at ground level is the arrangement of an obstruction over the entire width and length of a wall, which removes the slender supply of dampness normally ascending starting from the earliest stage. In outer walls, to stay away from rain water sprinkling up over the clammy confirmation course, the DPC (damp proofing course) must be situated no less than 6 inches (150mm) over the outside ground. All About Damp Proof Courses. ... wall brick support cad construction details that includes a detailed view of layer- wall core polystyrene base material thickness of ... Mar 22, 2014 · A damp proof course (dpc) is a layer of impermeable material built into the wall to prevent upward migration of ground water. Once in position, the brick laying continues as normal, covering the dpc with a bed of mortar and then laying the first course of bricks above dpc.

Types of DPC And Its Thickness. Currently, various remedial damp-proof courses are available which can be installed.However, it is important to select the appropriate damp proof course which will be well suited to the construction of the property.. The following are different types of DPC and its thickness used in construction,If the ground level on the outside contacts the outside wall above the damp proof layer then moisture can bypass the damp proof course and work its way inside. If there are damp patches above 1m from the ground level then it is most likely that you have penetrating damp instead of rising damp. A damp-proof membrane (DPM) is a membrane material applied to prevent moisture transmission. Typically, a DPM is a polyethylene sheet laid under a concrete slab to prevent the concrete from gaining moisture through capillary action . The approved document suggests that a ground-supported floor will meet these requirements if the ground is ...

Cement concrete is however, commonly adopted material for DPC at plinth level, 38 to 50mm thick layer of cement concrete M15 (1:2:4 mix) serves the purpose under normal conditions. In the case of a damp and humid atmosphere, a richer mix of concrete should be used. The most common source of dampness is due to the capillary attraction of sub-soil water in the foundation and walls of the building. Water can penetrate the masonry through faulty sills, bad workmanship, etc. and hence in buildings, a layer of water repellent material called damp proof course (DPC) is introduced, which acts as a barrier against the capillary rise of water.Cement Concrete – Cement concrete with a ratio of 1:2:4 is a good damp proof course. It is generally provided in the building at the plinth level. Plastic Sheets – Plastic sheets are a very good course for damp proofing. They are made up of black polythene having a thickness up to 1 mm. Methods of Damp Proofing
