About Biorok

For over 30 years CLEVA-Crete™ has provided a proven global technology to improve the building process and final outcomes for all stakeholders.

There have been recent developments in the supply chain of building products and their compliance with the Australian Building code. The use of concrete has raised many concerns and challenges that CLEVA-Crete™ is able to solve.

The rapid growth of construction and property development along with climate change means Builders, Architects, Designers and Engineers are looking for smarter ways to protect the structures they build, minimize costs and maximize efficiency. CLEVA-Crete™ is the proven technology that helps them do just that.

Biorok’s priority is to provide substantiated, reliable, cost-effective and sustainable solutions to our clients. Our CLEVA-Crete™ product is suitable for any sized project and is readily available for any sized project throughout the Asia Pacific region and in many parts of Europe.


Biorok’s mission is to build confidence throughout the Asia Pacific region and most parts of Europe for the wisest choice in concrete admixtures that create super-structures and buildings which have a lengthened service life and enable builders to overcome on-site challenges during construction and a better end product and asset for each end user.

Effective in reducing

Plastic and drying shrinkage cracking

  • High evaporation rates of excess water during placement cause concrete to crack before it has set. CLEVA-Crete™ prevents this as it transforms the water to C-S-H Gel, removing the quick evaporation process (osmosis). This technology hinders the concrete’s ability to form capillary tubes enabling the concrete to set 25% faster. The finishing process is completed in good time with no delays.

Freezing and thaw spalling

  • The conversion of the excess water to C-S-H gel means there is no water left behind in the concrete to enable freezing. The steep and early setting curve means the concrete will set well before it has a chance to be affected by dropping temperatures.

Slab curl

  • Differences in temperature and/or moisture cause concrete slabs to curl upwards or downwards (the direction of the curl is dependent on the area’s moisture or temperature). Using CLEVA-Crete™ removes water ingress that would otherwise cause tubular capillaries that result in slab curl.


  • Converting the excess water to a structural forming gel that stops bleed capillaries from forming. Moisture is unable to leave the matrix, disallowing salt stain on the surface of the concrete.


  • When concrete is placed and compacted with topical sealers the cement and aggregate settle. The settlement of these solids causes excess water and entrapped air to shift, causing the lighter materials to rise. The sealers applied to the top of the concrete create fine layers and don’t always fully bind. CLEVA-Crete™ on the other hand, removes the excess water via dynamic reactions in the matrix of the concrete, preventing delamination.
