DYWIDAG Threadbar Anchors

DYWIDAG Threadbar Anchors are an actively tensioned ground anchor system and correspond to DIN 4125 and EN 1537 regulations. Due to the active tensioning, anticipated deformations of the system and deformations at the civil engineering measure are minimized or entirely eliminated. This applies both to temporary structures (e.g. temporary pit support systems) and permanent tie backs.

By definition, an DYWIDAG Threadbar consists of three main components:
1. Bonded length: The DYWIDAG Threadbar is fixed in the borehole using grout (cement mortar) and can transfer the forces to the load- bearing soil via bond and skin friction.

2. Unbonded length: The bar is uncoupled from the borehole using a plain tube (sheathing) so that it can freely extend in the unbonded length. This way, tension can be applied to the anchor system.

3. Anchor head: The DYWIDAG Threadbar head transfers the anchor force to the substructure and thus to the structure that needs to be anchored

Once the grout has sufficiently hardened, the load bearing capacity of each anchor is tested during an approval test.
