The ‘Stealth’ anchor is designed to cover a wide range of lightweight anchoring. Its streamlined shape and chisel drive point makes installation easy, in most cases, using simple hand or light weight power tools. This also makes it an ideal choice when working in areas with restricted access, while its narrow profile means that it only requires a small core hole to drive through an existing wall.
The ‘Bat’ anchor is designed to achieve higher loads and enhance anchoring in weaker soils. Its ability to accept the T-Loc lower termination allows flexibility with regards to on-site anchor system selection and assembly. It also means it can accept a wide range of tendons and all thread rods. Installation requires more powerful equipment, typically a lightweight machine with a mounted hydraulic breaker.
Typical Anchor Behavior
The stress distribution in front of a tensioned anchor can be modelled using geotechnical fundamental foundation theories. The ultimate performance of an anchor within the soil is defined by the load at which the stress concentration immediately in front of the anchor exceeds the bearing capacity of the soil. Factors that will affect the ultimate performance of the anchor include:
- Shear angle of the soil
- Size of the anchor
- Depth of installation
