Pioneer House is a landmark building in the centre of Dewsbury, it has dominated the skyline since 1878.

Built initially for Dewsbury Pioneers industrial society from which to sell its produce and wares. It has however been dogged by controversy in more recent times allowing it to fall into a poor state of repair.

Kirklees Council and the Princes Trust are however working together to revamp the building and bring it back into full use.

The neglect over the years has impacted on the structural integrity of the building in a couple of areas, as a result additional structural support works were required. The main area of concern was the break in the bond between the external walls and a number of internal walls. This de-bonding was allowing the external walls to bow outward slightly

A number of repair methods were considered; as the aesthetics of the repair was a key consideration many repair methods were soon disregarded.

The Cintec Anchor was a method considered, as this could be secured discreetly into the centre of the walls it soon became the preferred choice of repair.

Deepshield as part of the Brick-Tie business is one of the main Cintec approved installer in the North, we have a rich history of installing Cintec anchors and other structural repair products, and we have installed them into some of the North’s most prestigious buildings, such as Riber Castle, York City walls and Armley prison to name but a few.

The Cintec anchor is effectively a reinforcement bar, which is surrounded in a fabric sock. After drilling over sized holes through the affected external and internal walls, we set the anchor in place ensuring it bridged the crack or defective areas between the walls.   

Once in place, we injected under pressure the specialist cementitious grout, this was injected down the fitted delivery tube in the middle of the anchor. At the opposite end of this delivery tube are flood holes, these allow the grout to spill into the rear section of the sock filling and inflating it from the back.

We injected the grout until the whole sock had become fully inflated; this is confirmed by the inflation of the front visible section of the sock.

As the sock expands within the wall it molds itself to the masonry, filling any surrounding undulations or voids. Small amounts of grout passes through the sock and creates a further mechanical bond to the masonry. During the installation of the anchour the face of the building was kept clean by flushing off any residue with a constant supply of clean water.

Once the anchor had been installed and the grout had cured we carried out our usual pull out tests to ensure a satisfactory installation, we do where possible on all projects. The tests revealed a satisfying 100% pass rate on the anchors tested.

Now satisfied that the installation was a success the drilled holes were filled to match the surrounding masonry.

As all Cintec anchors are designed specifically for the loads and configuration required on each project, Pioneer House is now in safe hands.

We are also Helifix approved contractors, so if you require expert help and advice please don't hesitate to call.
