Kongcrete™is a revolutionary new way to install fence & sign posts. It is a high strength alternative to concrete that is lightweight, does not require water, sets in 3 minutes and is extremely easy to use.Kongcrete™ is a hydrophobic (insensitive to water) two-part composite backfill that expands to fill the peripheral void between a fence or sign post and the hole. Kongcrete™ expands immediately after mixing and reaches 50% of full strength in approximately 3 minutes. In approximately 15-30 minutes Kongcrete™ will already be quite hard. Fences or gates can be installed after the product completely sets in approximately 2 hours.
Kongcrete™ can be used to install many different types of posts such as fence and sign posts, road and construction signs, as well as mail boxes and light poles.

Kongcrete™ can be used outside in summer and winter, even when temperatures are as low as -30°C (-20°F) or as high as 38°C (100°F). However, the Kongcrete™ Kit must be climatised at 18°C - 25°C (65°F - 77°F) for at least two hours before Installation. For more detailed installation instructions, consult the Kongcrete™ Instruction Sheet or contact a Kongcrete representative.
Whilst every effort is made to ensure it’s accuracy, the data held on this sheet is meant for informational purposes only. The typical properties listed are the result of extensive laboratory tests, but since Kongcrete Ltd has no control over the end use of each material, the Company cannot guarantee that these results will be obtained in practice. Users should conduct their own tests to determine the suitability of each material for its intended application.
