CHEM-CRETE PAVIX® CCC100

Concrete Protection Against Water, Moisture & Ice and Durability Solution by Pore Blocking and Lining Using Topical Treatment for Green & Cured Concrete for Airports, Highways & Bridges Structures

Chem-Crete® PAVIX® CCC100, is a patented Dual-Crystalline, penetrating concrete and masonry sealer. It is a water-based and environmentally-friendly waterproofing product that combines hygroscopic and hydrophilic crystals for pore-blocking function, and hydrophobic material for pore lining. It is designed to protect surfaces from the delaminating effects of water, moisture saturation, freeze/thaw, Alkali Silica Reactions (ASR), chloride-ion penetration and ice adhesion. PAVIX is ideal for exterior or interior concrete and masonry surfaces and can be applied to both positive or negative hydrostatic pressure sides of concrete. PAVIX enhances concrete sustainability, significantly reduces maintenance costs and increases concrete and masonry life cycles.

ADVANTAGES, FEATURES & BENIFITS

  • Can be used on green (fresh) and cured concrete.
  • Provides long-lasting internal waterproofing and moisture blocking from positive and negative sides.
  • Reduces water permeability through concrete by 2-3 orders of magnitudes when tested @ 200 psi (1.38 MPa) according to CRD-48-92.
  • Provides concrete surface with Hydrophobicity characteristics: Excellent water-repelling properties that help prevent water, jet fuel, and oil from wetting and saturating concrete surfaces: PAVIX increases water contact angle for concrete surfaces by greater than 90°, see Fig. 1).

APPLICATION

Limitations: Do not apply PAVIX in the following cases:

  • If the concrete surface temperature falls below 40°F (5°C).
  • If the area has been previously treated with sealing agents unless the sealers are removed by chemical or mechanical

 

Application:

Fully cured or existing concrete: Repair and seal joints, cracks, and voids greater than 1/16th inch prior to application. Concrete surfaces must be clean and sound prior to the application of the product. Proper cleaning will open the surface pores and capillaries to enhance the penetration process. Compressed air can be used to remove dust and loose particles from the surface. Flushing the area to be treated with water can improve the cleaning process. However, for heavily contaminated areas special concrete cleaning agents such as Chem-Crete CONCLEAN CCC060 can be used to remove dirt, grease, and oil from those areas.

 

Coverage: Apply at an average coverage rate of 150-200 ft2/gal (3.7-4.9 m2/liter) in one coat.

 

Green/Plastic Concrete:

  1. Only consider an application when concrete finishing is completed and the disappearance of bleed water.
  2. Concrete should not be in duress and should be curing normally.
  3. Apply PAVIX uniformly and at an average coverage rate of 200 ft2/gallon (4.9 m2/L).
  4. DO NOT allow the PAVIX to puddle or pool.
  5. Application of membrane-forming curing compound within 20 minutes from the initial PAVIX application.
  6. Apply the membrane curing compound at the manufacturer’s recommended coverage rate.

 

Cleaning: all tools and equipment must be cleaned with clean water immediately after use.

STORAGE

PAVIX   must   be   stored   under   room   temperature. Cold temperatures may cause the product to crystallize. Shelf life is two years in its original unopened packaging. Do not allow product to freeze.

SAFETY

As with all construction chemical products, adequate precautions and care must be taken during usage and storage. Avoid direct contact with foodstuff, eyes, skin, and mouth. Any direct contact with skin should be washed thoroughly with clean running water and soap.

 

Always wear protective goggles and gloves. In case of eye contact, flush for 15 minutes with warm water. If eye irritation persists, seek medical attention. In case of ingestion or swallowing, drink 2 glasses of clean water and seek medical attention. Keep out of reach of children.
