Waterproofing Lift Wells

The waterproofing of lift wells sometimes called lift pits, is an integral part of the building structure. The waterproofing of the lift pit should be designed into the pit well before the commencement of the building.

The consequences of a lift well failing and water ingress, even just dampness, can result in

  • Damage to the Lift mechanics
  • Damage to the lift electronics
  • Health & Safety Issues
  • loss of longevity of build structure and lift itself
  • Higher maintenance costs

Cementitious Waterproofing Methods using Drizoro Products

Assuming the concrete or masonry block base is in good condition and has not been damaged in the construction stage, little work is usually required other than to prepare the new substrate correctly and to apply a cementitious based waterproofing.
Please note that the timing of the application is as always extremely important in relation to the work of other trades carrying out other works to the pit which may damage the waterproofing membrane.

EXTERNAL Cementitious Waterproofing of Lift Wells:

  1. Preparation –  clean external walls remove efflorescence, and dampen. Surface must be damp but water should not running off the surface.
    Drizoro products come as premixed powders, add the prescribed amount of water (follow, DO READinstructions on bag, watch how to video links, contact us) and apply using stiff brush or MaxBrush, long handled broom/brush
  2. Fill all suspect areas using MAXREST
  3. Wet thoroughly apply MAXSEAL or MAXSEAL FLEX in 2 coats @ 1Kg/coat/m2. Ensure that surface is wet before applying the second coat.

Assuming the concrete or masonry block base is in good condition and has not been compromised, little work is usually required other than to prepare the substrate correctly and to apply a cementitious based waterproofing.

INTERNAL Waterproofing Lift Wells:

  1. Remove all render, paint or other material from the masonry substrate.
  2. Where dry fill voids and holes with MAXREST, fill leaking areas using MAXPLUG for all major water flow.
  3. Wet dampen area and apply MAXSEAL or MAXSEAL FLEX where there is residue of other materials.
  4. Allow to first coat to cure overnight, and seal any remaining water ingress using MAXPLUG .
  5. Dampen before applying the second coat of MAXSEAL.
  6. Always apply MAXSEAL or MAXSEAL FLEX in 2 coats @ 1Kg/coat/m2 wet between coats.

 

Note: For areas below water table additional coats may be required.
