SockFix

Mechanical grouted sock anchor systems for stabilising damaged masonry


Our extended range of SockFix mechanically grouted sock anchor systems ensures a solution for a wide variety of applications and repair solutions. The systems comprise of a grout-filled sock that combines with a bar in a composite action which expands to form a strong chemical/mechanical bond with the substrate.

The SockFix systems are used in light and heavy duty, high load applications. Including as a wall tie/consolidation tie, stabilising rubble-filled walls, securing external walls to hollow concrete floor slabs, stitching cracked solid and multi-leaf walls and securing unstable parapet walls and arches.

The most suitable SockFix type for your application will be identified by our Leviat Technical Area Managers or one of our Helifix Approved Installers.

Securing an external wall to a hollow concrete floor slab.

Installation

SockFix is installed through pre-drilled hole in structure.

Grout is pumped slowly, expanding the sock to fill the hole. Fluid permeates through the sock to provide a bond with the substrate while a solid aggregate bar/grout composite is formed in the sock.
