Heritage and Historic Paving - Online Shop

Heritage Buildings or Areas of Historic importance often have individual and historically important traditionally paved areas around them. Of course this has to retain its original appearance, but today these areas are also frequently required to accommodate modern living and need to be integrated into our modern City infrastructure - particularly around many historic buildings such as our Cathedrals and Churches, Town Halls, Old Market Squares and other types of Conservation Areas.

Paving Jointing Mortars for Heritage Areas

Paving Jointing Problems in Historic Paved Areas

Paving Jointing Mortars for Heritage and Historic Paved areas can be very important and the jointing can frequently give rise to considerable problems and even damage to the original stone and surrounding area and substructures. This is because many historic areas of traditional stone paving are now in the centre of modern town centre or other Public or private commercial developments and are required to be used frequently and often on a daily basis, by modern road traffic. Therefore the historic stone paving and its jointing mortar is trafficked much more heavily and frequently with heavy articulated vehicles of up to 40 tonnes, rather than hand or horse and ox drawn carts for example. Therefore they are also exposed to frequent de-icing salts, high-pressure water jet cleaning and mechanical street cleaning machines.

As a result in addition to the old requirements of exposure to the weather, pedestrians and relatively light wheeled vehicles, these additional demands are imposed on them and then the traditional lime or cement based paving jointing materials, even modern polymer modified ones, are unable to cope with these additional and severe exposure requirements.

Paving Joint Mortars for
Heritage & Historic Areas
In refurbishment situations brought about by the inevitable breakdown and failure of the cement based jointing mortars the Local Authorities and their professional advisors are faced with some significant problems to replace the deteriorated and broken down jointing i.e. there are different joint depths and varied joint shapes and widths - some very wide, there is often residual water in the joints, minimal closure periods are possible due to modern access requirements due to financial commitments or public vehicles and emergency services access etc.; then there is the additional vibration and abrasion from the increased frequency and load weights of the modern vehicular traffic, plus the aggressive Mechanical Street Cleaning machines, high pressure water jetting and the use of de-icing salts in winter.

There are also very often even more environmental demands in these refurbishment projects, as these areas can be required to be in almost constant use i.e. in Market Squares, Church and retail or commercial office building access and entrances etc. These additional requirements in these situations can also require that: the paving jointing mortars are stored, mixed and placed on-site without creating dust to disrupt the occupants; that the jointing mortars are moisture-tolerant during application and hardening, that they are fast to apply and harden rapidly to allow fast reopening of the areas, plus they must be non staining on the traditional stone surfaces. All-in-all a significant specification for the installation and performance in service of a paving jointing mortar, which can satisfactorily be met by any type of cement based materials or products.
