The Damp Proof Course to Existing Wall Estimating Calculator is used to calculate the Labour, Materials and Plant costs associated with installing new damp proof courses into an existing wall.  It can be used to estimate for the installation of either chemical or physical damp proof courses to mitigate rising damp problems.

To use the calculator choose the type of damp proofing treatment required and a suitable wall description for the wall to be treated. Open the worksheet for the wall that most closely matches your requirements and enter the correct wall treatment length. 


The Damp Proof Course to Existing Wall Estimating Calculator calculates the following items depending on the type of damp proofing selected:

  • Damp proofing cream
  • Damp proofing rods
  • Damp proofing courses
  • Replacement bricks and mortar
  • Plus all labour and plant associated with the above.


The Damp Proof Course to Existing Wall Calculator is not linked to the Specification.
