  Recommended Reading: Salt Attack & Rising Damp in Buildings

  This publication is a great reference for builders and for anyone considering building or renovating - particularly for understanding rising damp in older houses. Salt can be an incredibly destructive compound, and understanding how salt damp behaves is the first step in designing a solution to control and prevent salt attack. Efflock is an ideal product to prevent the transport of salt throughout masonry. Efflock is excellent for use in new construction to prevent efflorescence and damp problems in tiled patios and wet areas, but can be used in many different applications such as render and brick mortar. It can sometimes however,...

A modern DPC is typically a black embossed polythene roll that is laid out directly beneath ant-capping, or just below finished ground floor level. In the past, DPCs have been made of lead, slate, malthoid, and sometimes special bricks. What is not usually considered, is that rising damp can...
