The Cavity Drain Membrane to Floors Estimating Calculator is used to calculate the Labour, Materials and Plant and costs associated with damp proofing floors using a cavity drain membrane system. It should be used in conjunction with the Cavity Drain Membrane to Walls Estimating Calculator to make a complete cellar or basement damp proofing system.

The Cavity Drain Membrane to Floors Estimating Calculator calculates the following items:

  • Cavity floor drain membrane
  • Membrane taping
  • Drainage channels and accessories
  • Floor screeds
  • Infill insulation (between drainage channels)
  • Plus all labour associated with the above.


The Cavity Drain Membrane to Floors Estimating Calculator is not linked to the Specification.


NOTE:

If a drainage sump and pump is required as part of the cavity drain membrane system use the Basement Sump and Pump Estimating Calculator in addition to the Cavity Drain Membrane to Walls and Cavity Drain Membrane to Floors Estimating Calculators to estimate for the complete system.
