While resin bound paving is the best surface choice for a smooth, visually pleasing and totally seamless finish, if the installation is taking place over more than one day this is not always possible.
In situations where the installation is over a large area, or there is an unexpected change in the weather, it is usual to install/allow for a joint within the surface. The options are to install a simple butt joint (day joint) or a neat architectural feature by incorporating a line of metal edging (decorative joint).
A day joint is usually created with a timber baton which the resin bound paving is laid up to at the end of one day forming a neat edge, and removed the following day. Fresh material is then laid up against the existing edge formed by the temporary edge.
Care should be taken to ensure the depth of the joint is consistent and its placement natural, for example following the edge of a building. The use of this type of joint can be planned or unplanned
Decorative (or feature) joints are usually supplied in aluminium or stainless steel and can either be single edging strip forming an unobtrusive narrow line in the surface or a wider type strip can be used which consists of parallel edging strips separated by an integral coloured filler strip.
This can be made to colour match to disguise it against the surface, or conversely can be contrasted with the resin bound gravel being laid.
Decorative joints are often chosen in preference to a day joint because they can be specified at an early stage in the planning, ensuring the most aesthetically pleasing result.
They are also a practical solution to demarcation, creating boundary lines or defining an area.
These joints are used over existing mechanical joints in the base, most commonly over concrete or where it is anticipated that movement may occur e.g. a bay joint in concrete or along a boundary between different types of base.
Movement joint covers can be similar in design to the decorative joints above and can be permanently incorporated into most schemes where the anticipated movement is not too great and is restricted to only lateral movement.
Where larger lateral movement and/or vertical or shear movement is a possibility more specialised covers can be used to provide a durable and visually acceptable solution.
All these joints are available through SureSet when planning your resin bound installation. If you would like any technical information or to discuss your project please call 01985 841180 or email us.
