Anchor Knob System (AKS) was developed more than 25 years ago by ALS in South Africa to combat the limitations of existing concrete protection liners.
It offers substantial improvements to the limitations of traditional spray applied and bonded coating systems. AKS is resistant to chemical and mechanical impact, high anchor pull out strength, time saving and reliable installation, fully welded and quality tested lining with low maintenance.
| KEY BENEFITS OF ANCHOR KNOB SYSTEM (AKS)* | |
|---|---|
| AKS Advantages | Spray Liners Disadvantages |
| Cast in structural concrete | Surface preparation or dampness issues |
| No on site mixing of material required | incorrect mixing of products |
| Pinhole and defect free | Pinholes in coating |
| Set thickness of lining from factory | Inconsistent thickness |
| Crack bridging | Live cracks in structure fail coating |
| Welding of seams is 100% quality tested | Ground water causes delamination |
| No curing required | Curing difficulties |
| Endures ground water inflow | Dark and humid working environment impede bond |
| Allows concrete vapour transmission | Concrete vapour transmission delamination |
