Restoration of Canadian Parliament
The Centre Block of the Parliament Buildings accommodates the House of Commons and the Senate. All Canadian law originates here. The original building was constructed between 1860 and 1865. After the fire of February 1916,
which totally destroyed the building except for the library, the building was rebuilt of Nepean sandstone.
The West Block, also constructed in 1860, was added to in 1878 and has also seen a major fire which in 1897 damaged the top storeys. Today this building contains the offices of the members of Parliament and staff, together
with the Confederation Room which is used for some state occasions.
Major repair and restoration works are being carried out over the next few years to ensure that these historic buildings continue to serve Canadians for many years to come.
CINTEC are involved in major repairs to both these buildings, where anchors up to 28ft long have been used to strengthen spires and masonry walls.
The use of the CINTEC system, in the restoration of these most highly valued buildings, demonstrates the excellent reputation CINTEC has developed in Canada in recent years.
Anchor Body: 15mm x 15mm x 1.5mm stainless or mild steel
Washer: 26mm steel washer welded at each end
Grout: Presstec grade A strength @28 days = 40N/mm2
Sock: 30mm Polyester Sock
18th Century Army Barracks Restored
The innovative CINTEC anchor system has been extensively used as part of restoration work in Dublin's historic Collins Barracks.
A photogrammetric survey of the walls of the 18th century army barracks indicated that significant movement had taken place in the stonework over time. A number of the main walls and archways required stablising, and the
ashlar granite face of the walls needed tying back to the core and inner skin.
Internal alterations at the barracks involved the installation of steel framing to support and stabilise the remaining walls. CINTEC anchors were chosen to tie the granite facing back to the body of the wall and to tie the
walls to the steel framework.
"Over time, archways in both the East and West blocks of the barracks had moved outwards from the intervening floors or vaults:' explained Brian Campbell, design engineer for the installers.
CINTEC anchors provided the practical, engineered solution to such problems. Anchors measuring 3.6 metres were installed in the west block, to tie the walls of the archway to the backing wall of the cloister, through the
brick vaulting.
 Two outer walls of arches in the East block were tied together using anchors installed in the 1100mm thick walls
and linked through the building with tie bars and turnbuckles. Here, the anchors were enlarged to form pattresses within the wall, and the core holes were plugged to match the granite, leaving no visible signs of repair from the outside.
Alterations about the turn of the century included the construction of a gable wall on the North block, which had later separated from the main wall - CINTEC anchors were used to stitch the two walls together.
"Using the CINTEC anchors we were able, following tests, to ensure a sound anchorage, without the loss of grout, as the sock followed the shape of voids in the rubble:' said Brian Campbell.
The restoration work at the barracks was undertaken by ACE Fixings, the approved installers of the CINTEC anchoring system for Ireland.
Keeping the Trains On Time!
 The trains approaching and leaving Fenchurch Street Station are now controlled by a new
signaling board which is cantilevered over the tracks from a single fixing position on a brick-built viaduct.
Although it may sound very straightforward, the forces generated by the board are immense.
In addition to the loads imposed by the weight of the board, there are colossal wind loads acting on the board and these are fed onto a single point in a brick structure.
Using a 200mm diameter drill, WT Specialist Contracts prepared an 8 metre deep hole. Into this they inserted a 160mm stainless steel tube which was surrounded by a grout sock to contain the grout mix. The mix was then
injected under pressure into the tube, and escaping through the holes at its base filled the sock from the bottom up to the top.
The finished result is now able to withstand all the loadings placed upon it and yet also be totally unobtrusive.
NYPD call on CINTEC for quick fix
CINTEC anchors have been used to secure decorative mouldings for the New York Police Department, in the historic area of Brooklyn Heights -just a few yards from the famous Brooklyn Bridge.
The task, to stitch a decorative stone surround onto the building, was undertaken on behalf of the Intelligence Division of the NYPD.
John Moran, an officer at the NYPD said "I had no idea how easy and quick the system was, I look forward to other projects where we can use CINTEC".
RAPID RESPONSE SERVICE
Following periods of torrential rain and a minor earthquake last October (Friday 27), the roof and sections of walls collapsed at the "Real Audencia" an historic listed building in Puerto RICO.
On the evening of the 27th CINTEC received a call from the Engineer and Conservation Consultant Martin Weaver, within 48 hrs the engineer and a representative from CINTEC were on site with the test anchors and installation
equipment.
The historic building which was constructed in 1710 had been left derelict in recent years pending restoration and its original roof structure had been covered with a temporary sheet metal structure.
An inspection of the site on Tuesday 31st of October confirmed that the walls were made of calicanto, a combination of sand, limestone and brick rubble. With the help of a local contractor test anchors were installed. Two
days later these were tested in order to determine what strength could be achieved in what was believed to be a weak substrate. The 3/8" (10mm) diameter anchor embedded 8 of achieved loads of up to 4,000lbs (20kN).
The project is ongoing and with all the information obtained, the project engineers UMA Engineering were able to design the CINTEC anchors which will be used in the restoration of this fine old building.
 CINTEC anchors have been used to fix two 20 ton lock gates, as part of the 750 million pounds sterling,
regeneration of Belfast's Laganside Development.
Clarendon Docks, where shipbuilding in Belfast first commenced, was severely affected by the river's tidal range. Construction of a temporary dam across the existing dock basin, and installation of a lock between the basin
and the river, has created an aesthetically pleasing non-tidal water feature capable of facilitating small craft.
Although the dock basin was pumped dry for the refurbishment of the waterfront site, it was vital that the fixing method selected was suitable for use underwater.
"Each gate is supported by two hinges bolted into the 600mm concrete wall of the lock. One of the key reasons for selecting the CINTEC system, was that although the top hinge for each gate is well above the water level,
the lower hinge falls within the tidal zone," explained Brian Campbell, design engineer for the installers.
"During the installation, sea-water poured through at one of the anchor locations. We were concerned that alternative fixing methods would not be as successful in such wet conditions."
Following extensive testing, 48 CINTEC anchors were embedded into the wall to support the two lock gates. Each lower hinge required 12 fixing anchors, 450mm in length and 102mm in diameter at 200 and 220 centres.
The installation of the anchor bolts at the lock gates has been undertaken by ACE Fixings, the approved installers of the CINTEC anchoring system for Ireland.
CINTEC CONTINUES TO SUPPORT INDUSTRIAL HERITAGE
 CINTEC anchors have been used to repair a large number of World Heritage sites. Their latest application has
been to restore Grand Hornu - an industrial archaeological site in Belgium.
Built in 1850 the site was used as a working coal mine unit until production was halted in 1954 when the Belgium coal industry was rationalised.
Left abandoned the complex started to fall into disrepair until it was bought by an architect from Hornu in 1971. Restoration of the site has continued since 1989, when the Province of Hainaut assumed ownership of Grand-Hornu.
The industrial ruins are now used as a museum and open air theatre, although the Province of Hainaut plans to create an economic and cultural development centre on the site.
Comprising warehouses, stables, iron and brass foundries, coke fired furnaces, neoclassical workshops and offices, the site is centred around two magnificent courtyards.
Bordered by enormous archways the main courtyard has led to the complex being known locally as 'La Cathedrale'.
Three of the impressive arches that surround the magnificent courtyard have already been restored using 224 CINTEC anchors. Used to stabilise the brickwork, the anchors measure 1.40m in length, and the next stage of repair
is about to get underway.
The restoration work is being undertaken by the Belgian approved agents and consultants EDRP, and Sintra, the approved installers
Based in South Wales, U.K. Cavity Lock Systems has extended , its reputation across the world, saving numerous buildings and structures in the process. From the Northern to the Southern hemisphere, CINTEC
anchors can be found, but not seen.
AMERICA
Norfolk Virginia: CINTEC supplied 5ft long anchors to be installed into the tower of the First Presbyterian Church. The problems encountered came to light when this old established
church was carrying out major improvements to the organ. The anchor installation was a matter of great urgency. Leavitt Associates the engineers, authorized the work on a Thursday night and the following Monday morning (less than 2 working days) the
anchors were on site and by Tuesday midmorning Hoy Construction with the help of CINTEC personnel had completed the project.
Universities: CINTEC have recently been involved with repairs to The Stirling Library at Yale University, The Statistics Building at Colorado State University and Osgoode Hall at
York University, Toronto.
AUSTRALIA
Sydney, N.S.W.: CINTEC anchors have been installed to strengthen the historic sandstone St Philip's Church, near the southern end of the Sydnes Harbour Bridge.
Maitland, N.S.W.: 7 metre long anchors are being used to strengthen the buttresses of the 140 year old Uniting (formerly Methodist) Church at Maitland, in the Hunter Valley of New
South Wales.
Bathurst, N.S.W.: CINTEC anchors have been used to stitch the rubble stone walls of the historic Bunnamagoo Homestead, near Bathurst.
CANADA
Toronto, Ontario: CINTEC Anchors saved the last remaining chimney of Toronto's most significant Brickworks. The 16ft long anchors were specified by Halsall Associates. Further
information on this project will appear in the next issue of CINTEC News.
Kingston, Ontario: Roney Engineering working on the repairs of a listed building recently specified the use of CINTEC 3/8" x 18" long anchors to tie the two wyths of old
masonry walls together. Hans & Michael the masonry contractor, had the anchors specially designed so that they could be altered on site to accommodate the variable thickness of the wall. Hans Yaeger said "the system is simple, quick and easy to
use".
