Envirocrete™

What is Envirocrete™

Envirocrete™ is an integral waterproofing consisting of Portland cement, treated silica sand and various active chemicals. Added to concrete at batching, Envirocrete™ generates non-soluble crystals throughout the capillaries and pores in the concrete, creating a physical barrier to water.

    INSTALLATION

    For waterproofing concrete, the recommended addition rate for Envirocrete™ is 0.8% – 1.2% by weight of cement. For enhanced chemical resistance please consult with Elmich to determine the approximate addition rate.

    Envirocrete™ is 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.

    An ideal water cement ratio of 0.42± to ensure Envirocrete™ performs as specified.

    Curing

    Normal practices for placing and curing concrete should be followed as laid out in your local standards.
