PENETRON® Admix is added to the concrete mix at the time of batching.

PENETRON® Admix consists of Portland cement, very fine treated silica sand and various active, proprietary chemicals. These active chemicals react with the moisture in fresh concrete and the by-products of cement hydration to cause a catalytic reaction, which generates a non-soluble crystalline formation throughout the pores and capillary tracts of the concrete.

Thus the concrete becomes permanently sealed against the penetration of water or liquids from any direction. The concrete is also protected from deterioration due to harsh environmental conditions.

    Resists extreme hydrostatic pressure from either positive or negative surface of the concrete slab
    Becomes an integral part of the substrate
    Highly resistant to aggressive chemicals
    Can seal hairline cracks up to 0.4 mm
    Allows concrete to breathe
    Less costly to apply than most other methods
    Permanent; Added to the concrete at time of batching and therefore is not subject to climatic restraints
    Increases flexibility in construction scheduling

Setting Time: The setting time is affected by the chemical and physical composition of ingredients, temperature of the concrete, and climatic conditions. Retardation of set may occur when using PENETRON® Admix. The amount of retardation will depend upon the concrete mix design and the dosage rate of the Admix. However, under normal conditions, the Admix will provide a normal set concrete.

Dosage Rate PENETRON® Admix: 0.8% of cement by weight
Shelf Life: 12 Months in unopened, undamaged bags
Packing: 40 lb. (18 kg) bags, 55 lb. (25 kg) pails. For large projects, customized packaging is available.

NOTE: Under certain conditions, the dosage rate may be between 2-3% depending on the quantity and type of total cementitious materials. Consult with PENETRON's Technical Department for assistance in determining the appropriate dosage rate and for further information regarding enhanced chemical resistance, optimum concrete performance, or meeting the specific requirements and conditions of your project.


PENETRON® Admix must be added to the concrete at the time of batching, The sequence of procedures for addition will vary according to the type of batch plant operation and equipment:

   1. Ready-Mix Plant Dry Batch Operation:Add PENETRON® Admix in powder form to the drum of the ready-mix truck. Drive the truck under the batch plant and add 60% - 70% of the required water along with 300 - 500 lb. (136 - 227 kg) of aggregate. Mix the materials for 2 - 3 minutes to ensure the Admix is distributed evenly throughout the mix water. Add the balance of materials to the ready-mix truck in accordance with standard batch practices.
   2. Ready-Mix Plant Central Mix Operation: Mix PENETRON® Admix with water to form a very thin slurry (e.g. 40 lb./18 kg of powder mixed with 6 gallons/ 22.7 liters of water). Pour the required amount of material into the drum of the ready-mix truck. The aggregate, cement and water should be batched and mixed in the plant in accordance with standard practices (taking into account the quantity of water that has already been placed in the ready-mix truck). Pour the concrete into the truck and mix for at least 5 minutes to ensure even distribution of the PENETRON® Admix throughout the concrete.
   3. Precast Batch Plant: Add Penetron Admix to the rock and sand, then mix thoroughly for 2 - 3 minutes before adding the cement and water. The total concrete mass should be blended using standard practices.

NOTE: It is important to obtain a homogeneous mixture of PENETRON® Admix with the concrete. Therefore, do not add dry Admix powder directly to wet concrete as this may cause clumping and thorough dispersion will not occur.


    Concrete containing PENETRON® Admix may develop higher ultimate strengths than plain concrete. Trial mixes should be carried out under project conditions to determine setting time and strength of the concrete.
    PENETRON® products must be stored dry at a minimum temperature of 45ºF (7ºC).
    When incorporating PENETRON® Admix, the temperature of the concrete mix should be above 40ºF (4ºC).
    For further information regarding the proper use of Penetron Admix for a specific project, alternative application methods, or information concerning the compatibility of the PENETRON® treatment with other products or technologies, contact the Technical Department of ICS/Penetron International Ltd. or your local PENETRON® representative.
    PENETRON® is alkaline. As a cementitious powder or mixture, PENETRON® may cause significant skin and eye irritation. Directions for treating these problems are clearly detailed on all PENETRON® pails and packaging. ICS/Penetron International Ltd. also maintains comprehensive and up-to-date Material Safety Data Sheets on all its products. Each sheet contains health and safety information for the protection of your employees and customers. Contact ICS/Penetron International Ltd. or your local Penetron representative to obtain copies of Material Safety Data Sheets prior to product storage or use.
