Our Sock Anchor system provides a discreet, reliable solution for stabilising damaged masonry structures — ideal for heritage applications, listed building renovations, and refurbishment projects where maintaining original appearance is essential.

The system consists of a high-strength stainless-steel Rib Bar encased within a woven elastic polyester Grout Sock, sealed at both ends. Once inserted into a pre-drilled hole, grout is injected into the sock, which expands to fill the contours of the hole. The sock acts as temporary shuttering, allowing water to pass through and create an intimate chemical bond with the surrounding material. When cured, the Rib Bar and grout form an integral, permanent reinforcement within the structure.

Where structures contain sharp or granular fill, a reusable protective sleeve can be used to prevent damage during installation. The exposed section of the Rib Bar allows for proof testing or load plate attachment, which can then be concealed to preserve the original façade.

Why Choose Sock Anchors

Compared to traditional methods such as partial or full wall rebuilds, Sock Anchors offer a faster, cleaner, and more cost-effective solution that preserves the integrity of historical and existing structures. This system avoids the need for heavy wet trades, reduces material use, and limits disruption to the surrounding area.
