Expansion Anchor B15

The Expansion Anchor B15 is designed for fast, single‑sided fixing of formwork to rock faces and concrete walls. Manufactured from zinc‑plated steel, it offers durable performance under site conditions and can be reused in multiple locations. The anchor thread matches standard B15 form ties, allowing it to be integrated directly into existing formwork systems without additional adapters. In C20/25 concrete the anchor provides a load capacity of 90 kN with a minimum drill depth of 200 mm, enabling secure support of single‑sided formwork even under high fresh‑concrete pressure. The required hole diameter of 36.5–38 mm makes drill selection straightforward and ensures proper expansion in the substrate. Its suitability for both rock and concrete makes the Expansion Anchor B15 a practical solution for stabilising excavations, hanging formwork for retaining walls and for tunnelling applications.
