3 Reasons to Use a Concrete Waterproofing Admixture

The performance and lifetime of concrete is essential no matter the structure. When concrete deteriorates, its repair takes a considerable amount of time, money, and manpower, which is why anyone working with concrete would want to get the most of it from the start. Tecnorap USA’s concrete waterproofing admixture, CWS Admix, is the most effective, longest-lasting waterproofing admixture in the industry. Concrete is meant to be durable—that’s its beauty—but it can only perform so well if not produced and placed properly to set it up for success once hardened. If not mixed and applied well, it’s left vulnerable to moisture penetration, even if you can’t visibly detect cracks or pores. CWS Admix ensures you never have to doubt the durability of your concrete or worry about water penetration.

CWS Admix is a game-changing product for anyone working with concrete. Why?

  1. It’s easy to use.
    CWS Admix is a blend of moisture-activated chemicals, high-grade fine aggregates, and selected high-performance cements. The mixture releases a crystalline chain reaction when mixed with water and applied to a concrete surface or when added to fresh concrete as an admixture. The solution then penetrates far into the concrete’s fissures and cracks. The product repels moisture, providing watertight concrete, but still allows concrete to breathe. CWS Admix will continue to reactivate whenever it comes in contact with any future moisture, resealing concrete time and time again.
  2. It provides peace of mind.
    When you incorporate CWS Admix into your concrete, you don’t have to worry about how the concrete will hold up. When used properly, the product provides superior lifetime protection. CWS Admix will continue to work for you over the years, never losing potency, so you don’t have to worry about potential needed repairs to concrete just a few years down the road.
  3. It has a range of suitable applications.
    CWS Admix has been proven effective for a wide variety of applications, including concrete basements, water tanks and towers, reservoirs, swimming pools, water treatment works, dams, canals, harbors, concrete pipes, lift pits, and more.

These are only a few reasons this concrete waterproofing admixture has become so popular. Other benefits include:

  • Lifelong waterproofing that won’t deteriorate
  • Immediate protection, eliminating delays
  • Dormant waterproofing protection
  • Protection from steel reinforcement corrosion
  • Use with negative and positive water pressure
  • Seamless, jointless, non-toxic, and self-healing performance
  • Water bar replacement in static construction joints
  • Faster activation with increased water exposure
  • Performance that isn’t reliant on adhesion or coating thickness


With all that in mind, it’s easy to see why CWS Admix has been revolutionary for the concrete industry. Questions? Just give our team at Tecnorap USA a call at (804) 330-6438 or learn more about CWS Admix on our website.
