Perma Plast-O-Proof


Water Proofing Compound


IS 2645-2003

Plast-O-Proof is an integral waterproofing compound, ideal for use with both Concrete and Plasters. Plast-O-Proof 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.
Water Proofing Compound


    Concrete and plasters admixed with PERMA Plast-O- Proof exhibit the following advantages:

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


Plast-O-Proof functions in the following manners:

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.


Add Plast-O-Proof in concrete and mortar along with water at the rate of 100 ml per bag of cement, in demanding situations the dosage could be doubled.


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 emphasized that integral waterproofer and plasticisers only help in making a good concrete better. Hence observance of good construction practices is of utmost importance for achieving the overall goal.PROPERTIES
