The Cavity Drain Membrane to Walls Estimating Calculator is used to calculate the Labour, Materials and Plant and costs associated with damp proofing walls using a cavity drain membrane system. It should be used in conjunction with the Cavity Drain Membrane to Floors Estimating Calculator to make a complete cellar or basement damp proofing system.
The Cavity Drain Membrane to Walls Estimating Calculator calculates the following items:
- Cavity drain membrane
- Fixings to cavity drain membrane
- Condensation strip
- Membrane taping
- Wall repairs and preparation
- Plus all labour associated with the above.
The Cavity Drain Membrane to Walls Estimating Calculator is not linked to the Specification.
NOTE:
The drainage channels necessary to remove any water from behind the membrane are accounted for in the Cavity Drain Membrane to Floors Estimating Calculator, both calculators are required to estimate the complete cavity drain membrane system.
