 Polythene sheet.

Saturday, January 1, 2011
 

Polythene sheet for use as a dpc should be black, low density polythene sheet of single thickness not less than 0.46 mm, weighing approximately 0.48 kg/m^2. Polythene sheet is flexible, can withstand distortion due to moderate settlement in a wall without damage and is an effective barrier against moisture. It is laid on an even bed of mortar and lapped at least the width of the dpc at running joints and intersections. Being a thin sheet material, polythene makes a thinner mortar joint than bitumen dpc, and is sometimes preferred for that reason.

Its disadvantage as a dpc is that it is fairly readily damaged by sharp particles in mortar or the coarse edges of brick.

  1. Polypropylene Sheet, commonly referred to as PP Sheet, has become one of the most widely used thermoplastic materials in various industries. Known for its excellent chemical resistance, lightweight nature, and high durability, the PP sheet manufacturer is a preferred choice for applications ranging from packaging to industrial equipment. Its popularity stems from the fact that it is cost-effective yet offers performance comparable to more expensive plastics.
