Paving cladding cobbles installations




Paving Guidelines:
The following is to be used as a guideline only. It is recommended by JustStone as the manufacturer, that before starting your project the existing ground must be evaluated and the relevant sub-base and preparation there-of, be done by the appointed contractor. It is important to remember that the quality of the installation greatly depends on the correct preparation of the area prior to the laying of the product.

JustStone does not do product installation and therefore cannot be held responsible for breakages, chipping or any defects which might arise as a result of incorrect procedures followed by the contractor or client when laying the product.

It is important that only experienced installers and contractors be used. Ask for references and do site inspections of other work done by the contractor before you commit yourself. Do not use installers who have little or no experience with this type of product.

Some practical tips when laying JustStone Products.

Pavers and Cobbles.

A well prepared sub-base which has been adequately compacted is essential.
Appropriate drainage is important and provision must be made for rain and water to run-off easily from the finished paved surface. Get the final levels correct from the start
To prevent weeds or grass growing through the joints between the pavers or cobbles a layer of bidim cloth can be put down over the sub-base. If the paving slabs are to be well grouted then the bidim cloth should not be necessary.
Once the sub-base is ready (with or without the bidim cloth) a 20 to 40mm layer of building sand dry mixed with cement in the ratio of 4:1 is evenly spread over the area.
Before laying the paving stones/cobblestones it is important that all surfaces are clean and free of debris and dust.
The pavers/cobbles can then be laid down directly onto the sand/cement mix base and bedded using a rubber mallet. JustStone products are manufactured to conform to stringent specifications and the paving slabs/cobbles can be butted against one another if little or no grouting is to be used (depending on the style of paving stones chosen). The thickness of the pavers is exceptionally uniform and little or no adjustments are needed in order to maintain a level surface. If the pavers are to be pointed or grouted a standard gap of 10 to 20mm is usual.
Once completed the surface can be given a light sprinkling of water (do not flood).
If the area is to be grouted or pointed, allow a couple of days in good dry weather conditions to allow the pavers or cobbles to settle and become solid before grouting.
Grouting cement or a semi-dry mix of sand and cement in the ratio of 3:1 can be used. Make sure that any grouting mix that spreads onto the paving stones is immediately removed using a damp cloth or sponge. Any grouting mix or cement left to dry on the pavers will leave a stain and will be difficult to remove.
Finally once the paving and grouting has been completed the area can be lightly sprinkled with water several times a day for a few days especially in hot weather.
Avoid walking on or allowing any heavy traffic such as wheel barrows, to use the paved area for a few days in order to let the paving settle and cure.

Tiles

Tiles are laid onto a concrete base using cement or tile adhesive cement. It is most important however, to make sure that the back of the tile is well cleaned using a wire brush or equivalent. Remember that the product is wet cast and in the process of curing, a fine layer of loose sand, cement or sludge is left on the back of the tiles. If this is not removed before the tiles are laid down then in time to come the tiles can work loose. It is also important to make sure that the entire back surface of the tile is wet, and coated with tile adhesive or cement. Using spots of adhesive will also result in tiles lifting in due course. Tiles are usually laid with a 1 or 2 cm grouting gap although, quite often for effect a larger grouting gap is used.

Cladding

Our cladding is designed to be butted closely together with no gap allowed for grouting. The castle Cladding can however be spaced and the finished product is then pointed as is often done with sandstone. As with the tiles it is equally important to ensure that the back surface of the cladding is well cleaned using a wire brush or equivalent. Also ensure that the back surface is wet before applying the tile adhesive. A rubber mallet is useful to help secure the cladding.
