Preparation & Application

Mixing

Mix 1 kg of weber.ad Barrier Cement Waterproofing Additive to a 50 kg bag of cement.

  • Mix the powder with the cement in a dry state, then add the aggregate and water.
  • Mix thoroughly but air entrapment and machine mixing of concrete is unduly prolonged once water is added.
  • Use only clean, sharp, well graded aggregates for concrete.

Please note:

In all cases the strength of the mix should be in accordance with the specification and SABS / ISO standards applicable to the particular work to be carried out. As a guide, however, concrete should contain not less than 300 kg of cement per cubic meter (although a richer mix is often necessary).

The addition weber.ad Barrier Cement Waterproofing Additive will not compensate for incorrectly proportioned mixes or for poorly compacted concrete. Mixes containing weber.ad Barrier Cement Waterproofing Additive are water repellent. For floors it is recommended that a vapour membrane be provided.
