Perma Plast-O-Proof STD


Integral Waterproofing Compound

IS 2645-2003


Perma Plast-O-Proof STD is an integral waterproofing compound ideal for use with both Concrete and Plasters. Perma Plast-O-Proof STD is based on specialized surfactants and synthetic resin which impart superior flow and cohesive properties in concrete and mortars. Use of integral waterproofing compounds in concrete and mortar is one of the precautions taken to achieve a waterproof concrete or plaster.

Integral Waterproofing Compound


    Concrete and Plasters admixed with Perma Plast-O-Proof STD exhibit the following advantages:

  • Durability is increased due to air entrainment.
  • Segregation, bleed and thereafter honeycombing is prevented.
  • Surface finish of concrete and plasters improved.
  • Attack by sulphates and chlorides from ground water in coastal areas is well tolerated.


Add Perma Plast-O-Proof STD in concrete and mortar along with water at the rate of 100 gms per bag of 50 kg cement. In demanding situations the dosage could be doubled to 200 gms.


Perma Plast-O-Proof STD functions in the following manner:

    In concrete:

  • It disrupts the capillary network within the concrete mass which could conduct water through concrete.
  • It significantly reduces water demand to bring down W/C ratio in the range of-0.45 which generally represents a sound concrete.
    In Mortar:

  • It reduces the possibility of shrinkage cracks.
  • It improves adhesive and tensile properties of mortar.
  • To improve workability and trowelling properties of sand/cement mortar mixes during application.


    A good waterproof concrete or plaster is achieved by good construction practices. Precautions to be taken to achieve the goals include:

  • Proper mix design.
  • Selection of good aggregates, sand and cement.
  • Adhering to W/C ratio in the range of 0.45.
  • Proper mixing, placing and curing.
  • Use of a good integral waterproofer.
  • It is emphasised that integral water proofers and plasticizers only help in making a good concrete better. Hence observance of good construction practices is of utmost importance for achieving the overall goal
