Wainford Bridge

Wainford Bridge in Northumberland. The image captured here is by Helen Wilkinson for ordinance survey purposes. The flooding here did not form part of our works.

Holes are drilled between the substrates to be secured using diamond drilling equipment.

Prior to insertion, the anchor must be handled with extreme care. The anchor must be wet with clean water, and the sock should be positioned evenly along the length of the anchor.

The anchor is placed in the bore hole and carefully pushed in and lifted over any fissures or voids. It is important that the anchor is not forced or twisted into the hole.

Fluid grout is then injected under pressure through the middle of the anchor and passes through a series of grout flood holes into the fabric sock which inflates like a balloon. Excess milk and bonding agent passes through the fabric sock, both fixing and providing a mechanical bond to the host.

Here, run-off ‘milk’ and grout is collected to prevent contamination of the river below.

A fully installed Cintec Anchor. The anchor will be hidden from site using a section of circular stone harvested from the diamond drilling at the start of the project.
Structural stabilisation of Wainford Bridge using a series of Cintec anchors to reconnect the downstream arch of the bridge which, had over the years become detached along the top line of the voussoirs as result of surface water from the adjacent hills. Fluid grout was also injected into the bridge to consolidate the core and fill any voids that had been created.
The holes to accommodate the anchors were diamond core drilled to reduce the amount of percussive energy in the positions indicated on the design. The anchors were subsequently installed and grout injected to fill the surrounding sock which inflated to ensure anchorage between voids along its length.
The river and surrounding area is considered to be a Site of Special Scientific Interest (SSI) therefore great care was required to prevent spillages onto the scaffold platform.
This project was added to our site on 22 September 2008 and is currently filed under Built Heritage and Structural Stabilisation.
