protection of engineering concrete and masonry

CONCRÈME™ is a specialist civil engineering product - the ultimate sealing technology for the protection of engineering concrete and masonry from damage caused by water and water borne salts.

Permanent bonding silanes have been routinely used across the globe for almost 50 years, as the best protective sealer for large concrete structures, particularly in salt water and de-icing salt environments. Silanes do, however, produce VOC emissions (alcohol) during the bonding process, so their use is being curtailed. California and Hong Kong are two places where use of silanes has been restricted with serious implications for the maintenance of large expensive concrete structures such as bridges, wharfs and highways.

CONCRÈME™ is a new technology - the worlds only low VOC, permanent bonding silane which passes California's new world best practice VOC guideline.

CONCRÈME™ is suitable for a wide variety of applications, including marine infrastructure (such as wharves and jetties), roads and rail bridge decks, building facades, car parks and swimming pool surrounds. It is an ideal product for the preservation of infrastructure.


  • Treated exposed surfaces become easier to maintain and keep looking good for longer
  • CONCRÈME™ is applied in a single easy application - ideal for windy conditions
  • Able to repel water and chloride ion (79 per cent reduction after 3 day immersion to NCHRP Report 244); non film-forming; deep penetration - 14 mm into concrete pavers giving protection against weather and traffic
  • Able to work without changing the appearance or frictional properties of the surface - keeps the original look; a non-drip gel to keep application control
  • Is able to breathe so there is no build-up of subsurface moisture - allowing it dry out and reducing electro-potential reinforcement corrosion
  • Very alkali resistant - won't breakdown in contact in high alkaline cement-based materials.
  • Already contains enough water for the silane cross-linking reactions - avoids the possible evaporation of active ingredients in very dry concrete
  • Able to seal hairline cracks up to 0.3 mm (0.012 in.)
  • Can be applied to previously impregnated surfaces and may be over-coated
  • Avoids the formation of unsightly efflorescence and freeze-thaw spalling
  • It is not a surface coating like epoxy, polyurethane or acrylic, so it will not flake, yellow or peel

Low VOC's:

VOC content to US EPA (Method 24, excluding water and exempt solvents) < 100 grams per litre - suitable for use throughout the USA. Fulfils the strictest LEED requirements. Compliant with EU VOC Directives 2004/42/CE and 1999/13/EC and Environmental Protection Department Hong Kong SAR Government 2007 Regulations.


15 Year Warranty


A 15-YEAR PERFORMANCE WARRANTY is offered when CONCRÈME™ is applied by an Accredited Applicator following our written instructions and tested by us.

VOC Content:

< 100 g/L for EPA purposes.

Pack size:

2.5 gallon (9.46 Litre) easy to carry pail.


  1. ALWAYS TEST PRODUCT ON A SMALL AREA FIRST and allow a 24-hour cure time to determine the ease of application and desired results.
  2. Surfaces to be treated must be dry, clean and free of residues, and surface temperature between 40 - 95°F (5 - 35°C).
  3. Generously coat the surface with an even layer of CONCRÈME™ using a foam roller, brush, low pressure sprayer or similar. Estimated application rate: 1 Quart per 30 sq.ft. (1 Litre per 3 sq.m.) depending on surface absorption and depth of impregnation required. One coat is usually sufficient but a second coat may be applied at any time once the surface becomes touch dry.
  4. Use water to clean equipment.
  5. Avoid moisture contact with the surface for a minimum of 12 hours after application.
  6. Sealer will NOT prevent surface etching, scuff marks or wear and may darken some surfaces temporarily, returning to the original color over time.


  1. On rough surfaces, globules of CONCRÈME™ may collect in gaps and pits. Use a paint brush to spread these out.
  2. For in-line manufacturing and large area applications CONCRÈME™ maybe applied using a hopper feed diaphragm airless spray unit.

Application rates:

One quart per 30 sq.ft. (1 litre per 3 sq.m.) depending on surface absorption and depth of impregnation required.
