Cem-Kote CW PLUS
New Dual Action waterproofing = Crystalline reactivity + Membrane waterproofing mechanism.
Result is an extremely Fast Activation – a few days, rather than weeks that are the norm for an old-style crystalline waterproofing. It can be used for negative and positive waterproofing as a brush-or spray-applied slurry.
Cem-Kote CW PLUS results in a very tough, hard, abrasion and impact resistant, well bonded surface
suitable even for heavy traffic.
Adi-Con CW PLUS
Adi-Con CW PLUS is an integral crystalline waterproofing admixture utilizing deep penetrating Nano-particles that react with the by-products of cement hydration (lime), and converts them into a new, non-soluble crystalline structure that “plugs” the capillary porosity, making concrete watertight even under extreme hydrostatic pressure.
Adi-Con CW PLUS blocks concrete capillary channels, producing 100% waterproof concrete that is self-sealing and water-pressure-resistant from any direction, and protects concrete from invasive compounds by sealing the capillaries, pores, and hairline cracks. Proven crystalline technology ensures waterproofing for the life of the concrete structure, not subject to deterioration issues encountered by membranes.
Cem-Kote CW Plus can be applied next day, after placing concrete
Polymer (epoxy or polyurethane) coatings require concrete to be cured for a minimum 28 days (most recommend 45 days) to prevent debonding. Installation of polymer coatings requires frequent testing to satisfy stringent surface “dryness” and very low humidity (35% relative humidity).
Dual Waterproofing Action
Cem-Kote CW Plus combines Crystalline Waterproofing + Membrane Waterproofing
Result is an extremely Fast Activation - a few days, rather than weeks that are the norm for an old-style crystalline waterproofing. It can be used for negative and positive waterproofing as a brush-or spray-applied slurry.
Structures treated with Cem-Kote CW Plus can be filled in less than 24 hours
3-day moisture cure is recommended for Cem-Kote CW Plus, but if needed it can be exposed to water after only overnight cure, since the membrane mechanism is fast acting.
Water Exposure Delay using old-style crystalline waterproofing is several weeks (or longer) since the reaction time of the reactive compounds into concrete is very slow and needs water.
Lack of Free Silicate
Cem-Kote CW Plus Waterproofs Concrete “starved” of free calcium ions
Cem-Kote CW Plus works successfully on concrete substrates “starved” of free calcium ions” due to carbonation provided by Membrane Waterproofing Mechanism.
Ordinary (old-style) crystalline waterproofing does not work in some old concrete structures, which due to carbonation have an insufficient amount of free silicate to react.
Cem-Kote CW Plus forms a continuous Waterproofing Membrane
Cem-Kote CW Plus positively waterproofs due to its Membrane waterproofing action.
Leaks in the structures often occur, because the amount of crystalline material is relatively small, and is insufficient to waterproof spaces (cavities) created by poor concrete consolidation, “sand pockets” in dry shotcrete, insufficient embedment of reinforcing steel, or due to the high porosity of concrete.
Longer Open Time + Easy Application
Cem-Kote CW Plus has a much longer open-time = Easier + Faster Application
Cem-Kote CW Plus is very easy to spray apply using conventional spray equipment, peristaltic or positive displacement, due to its excellent rheology and virtually no rebound.
Other crystalline materials have quite short “working time” after mixing, and higher ambient temperatures further shorten set times, resulting in very trying application.
Larger cracks are treated using Cem-Kote Flex ST + Reinforcing Fabric HD
Cem-Kote CW Plus system treats any larger substrate cracks using Reinforcing Fabric HD embedded in layer of Cem-Kote Flex ST - cracks are waterproofed quickly (overnight), allowing application of waterproofing system to proceed
Old-style crystalline materials can only seal non-moving, hairline cracks, and are unable to seal larger cracks that are moving due to temperature change and structural loading (filling & emptying tanks).
The “cut and fill” method used by conventional crystalline supplier is time consuming, costly and takes additional time to develop crystalline action to function properly.
Cem-Kote CW Plus has lower applied cost than old-style crystalline materials
Ease of application, longer open time and simpler and faster crack treatment of Cem-Kote CW Plus results in lower applied costs.
