PFAS contaminated concrete, asphalt, other solid wastes can continue to impact soil and water for decades.
The ISSUE is how to manage/remediate these polluted sources.
SOLUTION THE AMBIO RANGE OF PRODUCTS

Employing physical binding mechanisms, AMBIOLOCK restricts – limits PFAS movement through a stabilised concrete substrate matrix. Mechanisms for managing PFAS leaching out of solid material like impacted concrete. This patented technology controls and manages any existing impacted source materials through a process of encapsulation and stabilisation. It allows for Re-Use/Recycle of impacted materials on-site, or cintrolled disposal of the impacted material on or off-site.

AMBIOLOCK can be incorporated into a concrete substrate mix to achieve equal or greater material strength when compared to untreated concrete, while reducing leachable fractions of PFAS by up to 99%.

Trial Results

The following tables and figures detail the performance of Ambiolock for its proposed reuse in pavements and aprons. In short, its was noted that 99% of PFAS was arrested in the Ambiolock treated concrete (test period = 1 year) and that Ambiolock achieved a compressive strength equal to or greater than non-treated concreted, including for stabilised sand. Note that “Base” refers to types of concrete untreated with Ambiolock and are used here as a performance rate indicator. Ambiolock application conducted at low, nominal and high dose.

How AMBIOSEAL technology work

AMBIOSEAL is a two stage application utilising proprietary technology for controlling and managing any existing PFAS impacted structural materials through a non-toxic chemical treatment which achieves physical immobilization.

1st Stage – product applied on concrete structure

Sprayed or rolled on, provides a unique coating and penetrant hindering liquid and chemical contaminant transport from the impacted concrete or adjacent impacted materials.

2nd Stage – added protection and resistance

The 2nd coating enhances the long term wear resistance of an AMBIOSEAL coated concrete surface and assures maximum control of surface contaminant leaching.

AMBIOPROTECT is a proprietary product added at the time of batching during the manufacture of various concrete structures. It protects these structures from PFAS, and other potential contaminants, from nearby sources.

AMBIOPROTECT incorporate into a concrete substate mix to achieve equal or greater material strenght when compared to untreated concreate, resticting potential PFAS impact by up to 99%.

Environment
The AMBIOPROTECT technology limits retention of PFAS and/or other contaminants, helping to ensure that AMBIOPROTECT treated structures do not become potential secondary sources of contamination, and risk to human health or environmental.

Health & Safety
Workplace Health & Safety obligates a legal Duty of Care conforming with the standard criterion of what is reasonably practicable. Legally, Directors, Business Owners, Managers and others must eliminate risks in the workplace, and if not practicable to eliminate these, then minimise the risks to the extent possible. AMBIOLOCKPROTECT, and sister products, provide a cost-effective and viable solution for eliminating and managing PFAS risks associated with contaminated infrastructure.

Added Benefit

For every 1,000 m3 of concrete produced using AMBIOPROTECT, a possible reduction of approximately 82,000 kg CO2 may be achieved – reducing embodied carbon by around 10-15%+
