This prevents damage to the DPC specification on account of droppage of sharp edge implement or other materials during construction. As explained earlier immediately after laying, the DPC is protected with a course of brick laid flat on a cushion of finesand to prevent to damage to DPC specification on account of droppage of sharp edge of implement or other material during construction. Such bricks are widely used when damp proofing course is to inserted in an existing wall. Bricks being porous, brick masonry below ground level can be absorbing moisture from adjacent ground. The walls can get damp due to penetration of moisture from its external face to internal one, due to porosity of bricks and mortar joints. For the forming of sheet metal, such as automobile body parts, two parts may be used: one, called the punch, performs the stretching, bending, and/or blanking operation, while another part that is called the die block securely clamps the workpiece and provides similar stretching, bending, and/or blanking operation. Why Can’t the Cold Roll Forming Machine Be Overused | How to Avoid Failure? You can hit the button immediately and the machine will start rumbling when it’s ready while you take care of other business.

When choosing a C Z Purlin Roll Forming Machine, it’s important to consider factors such as production capacity, customization options, quality of the machine, maintenance requirements, and price. The flame serves to soften the glass being worked, so that the glass in a specific area of the workpiece becomes ductile and subject to forming either by inflation (“glassblowing”) or by deformation with a heat-resistant tool. For greater wall thickness or where D.P.C is laid over large area such as doors and roofs etc the choice is limited to flexible material which provide lesser number of joints like mastic asphalt, bitumen felt, felt plastic sheets etc. the felts when used should be properly bonded to the surface with joints properly lapped and sealed. III. Apply hot bitumen at the rate of 1.5 kg/m2 over the bitumen felt. III. Apply hot bitumen at the rate of 1.5 kg/m2 over the bitumen felt to serve as finishing coat. II. Lay bitumen felt in the singe layer over the primer coat. A75 to 100 mm thick layer of lean cement concrete (1:3:6 or 1:4:8) mix or lime concrete is thereafter laid over the base course. This moisture travels up from one course to another by capillary action and can make the wall damp for a considerable height.

For normal duty treatment or in places where the moisture ingress is not considered excessive, two layers of bitumen felts are used. With two decades of experience they have the capability to serve a range of industrial needs in various sectors. In areas of heavy rainfall, cement plaster 1: 4 mixed with water proofing compounds like Pudlo, Permo, etc. serve the purpose effectively. Ground water always produces hydrostatic pressure and as such poses great problem in design of basement. For D.P.C above ground level, with wall thickness generally not exceeding 40 cm, any of the material can be used which is describe above. For plastering work, the water proof mortar can be prepared. In water to be used, .75 N of soft soap is dissolved per litre of water and soap water is added to dry mixed. A small quantity of lime is added to increase the workability. These companies are capable of doing this job on a small scale as well as in bulk. We know well the particular requirements for the customers of different countries and regions. These techniques are well known within many circles, but few tutorials exist to help people get started.

And what we do is we help our customers and give solution. I was unsatisfied with this solution. Many kinds of CNC machines are used. We offer a huge variety of trim machines. IV. Lay another layer of bitumen felt in a single layer over the hot bitumen layer in step III above. In place where the sub soil water is high, or in damp or humid areas, where there is a possibility of moisture rising up in the floor, it is necessary to provide membrane DPC of flexible material like bitumen felt etc.over the entire area of flooring. In places where the soil water table is low and rainfall is not much, a 75 to 100 mm thick layer of coarse sand is first spread over the entire area of the flooring on the prepared bed of rammed earth. A composite steel deck combines the high tensile strength of steel with the compressive strength of concrete to improve design efficiency and reduce the material necessary to cover a given area. Various treatments given to exposed surface of the walls to prevent dampness include pointing, plastering and painting etc. It is observed that plaster made out of cement, lime and sand mixed in proportion of 1:1:6 serves as very effective rendering to protect the walls against dampness in normal weather conditions.
