SABS DPC 250um 110mm x 40m

DPC is an acronym for Damp-Proof-Course.  The main purpose of DPC waterproofing membrane is to prevent rising damp from entering load bearing walls that may cause weakening of structures, cracks in plaster and blistering of plaster or paint finishes on walls. DPC comes in various thicknesses of 250 microns or 375 microns.  DPC rolls are normally 40 meters long. The standard widths that are available are 110mm, 225mm, 300mm, and 450mm wide (of which the 110mm is made for a single brick wall, and the 225mm for a double brick wall.  Specific mechanical properties and strengths of the DPC membranes are described in the SANS 952 specification.  Apart from having a very low water vapor transmission rate (to prevent rising damp) the following properties are considered to be of vital importance for DPC membranes: It should have a high puncture resistance; It should have very good tensile properties (breaking strength and a high percentage elongation before it breaks); It should have a high resistance against accelerated aging.   ADVANTAGES & USES: Excellent tear and puncture resistant properties Prevents water from penetrating the walls Embossed film that will not age, rot or decay Light weight, flexible and easy to use
