CN2000 waterproofing in Ottawa and East Ontario

CN2000 waterproofing is one of the most innovative concrete waterproofing methods avaiable in market today. It is a durable, cost effective and non toxic concrete sealer for a wide variety of rcc waterproofing applications. As a unique crystalline waterproofing solution, it delivers superior results as compared to average concrete sealants. CN2000 enhances the life of your concrete structures and lowers mainenance costs. Preptech provides CN2000 waterproofing in Ottawa and East Ontario. Please contact us for comprehensive on-site analysis anywhere in Ottawa, Kingston or any other place in East Ontario to know how your infrastructure could benefit from CN2000 waterproofing.

Main Benefits of CN2000 Waterproofing, a Unique Capillary Crystalline Solution

  1.  Durable – Apply it once to get a long life solution. No call backs, complaints or re-applications.
    • Weather proof – CN2000 resists extreme dry/wet cycles and freeze/thaw cycles – Your weather worries will be solved. In a 1600 hours experiment, CN2000B was tested for 200 freeze-thaw cycles (-20 to 20 ℃) without any apparent damage to the concrete structure.
    • Corrosion resist – Resists carbonization and corrosion of other acid gases and acid water, chloride, sulphate, etc. thus significantly enhancing the life of concrete.
    • Self-healing nature – CN2000 self-rehabilitates cracks in structures (upto 4mm) to prevents leaks – you get a permanent solution. CN2000 becomes an integral part of the structure, increasing its strength, flexibility and life.
    • Superior Capillary Crystalline Waterproofing – CN2000 is a unique Cementitious Capillary Crystalline Waterproofing solution. As compared to other penetrating sealers and crystalline waterproofing solutions, the waterproof layer itself does not penetrate the cracks. Only the “activating chemicals” which act as catalyst in “capillary crystalline” role, help in formation of C-S-H crystal which is usually produced during the hydrating process of concrete itself. The activating chemical, acting as catalyst does not get consumed but still the continually produced C-S-H crystal makes the concrete substrate denser, thus preventing water and other harmful matters to invade.
  2. Cost effective -Reduce cost of construction, repair and maintenance.
    • Reduce your repair time and cost – CN2000 can be applied on positive (water pressure) or the negative side of concrete surface. In many cases, this means you can avoid expensive and time consuming digging and back fills.
    • Short curing time – CN2000 surface is cured and ready to use after 24 hours. You an speed up your projects with CN2000.
    • No sealing, lapping and finishing at corners and edges.
  3. Approved for Use
    • CN2000 series of products has received an “ACCEPTED FOR USE” (“A“) classification from the Ontario Provincial Standards (OPS) – Products Management Committee (PMC). See:
      • Standards met
        • ASTM C1202-12 – Electrical Indication of Concrete’s Ability to Resist Chloride Ion Penetration
        • BD11/ T380- 2006 – Bridge Deck Waterproofing Project Technical Regulations
        • GB18445-2001 – Cement-based infiltration crystalline waterproof material
        • ISO 9001:2008 – Quality management systems –Requirements
        • JC/T894-2001 – Polymer cement waterproof coating
      • Associated Standards
        • AASHTO T277-07-UL – Electrical Indication of Concrete’s Ability to Resist Chloride Ion Penetration
        • ASTM C666/C666M-03(2008) – Resistance of Concrete to Rapid Freezing and Thawing
  4. Non Toxic – All CN2000 products are non-toxic.

  • Recent Test Results :  As per study done at Queens University Department of Engineering, it was found that the use of CN2000 product helps delaying the water leakage by almost 22 times under an average water pressure of 3.3 MPa and an average triaxial pressure of 5.0 MPa. It should be noted that the 3.3 MPa water pressure is quite significant and likely higher than the pressures common (non-specialized) concrete structures are typically exposed to. The use of the CN2000 product helped reducing the water migration through the concrete samples significantly. More test results can be read on Kelso Coatings site.
