JustPave Paving Installation

The JustPave Vitfrified Paving Collection is a range of high performance hard-wearing, anti-slip outdoor products that combine exceptional strength and technical consistency. These vitrified paving flags absorb little or no moisture providing exceptional stain resistance, and allow moss and algae little opportunity to grow. This means minimal maintenance is required to keep your outside spaces looking stunning.

JustPave can be easily laid dry on sand, grass or gravel. This process is fast to install without the need for highly skilled labour and the pavers can easily be lifted, moved and repositioned if required. Alternatively, they can be installed on raised adjustable height pedestals over new or existing surfaces that will allow access below for substrate maintenance, pipework, electrics etc. This is ideal for installations on balconies or patios where access to waterproofing membrane or pipework may be required.

For more permanent placements the vitrified pavers can be installed using traditional paving methods with a standard sand/cement mortar on a hardcore substrate. For areas with regular heavy foot traffic or loads from cars etc. they can be laid onto a concrete base using highly deformable external grade adhesive such as Mapei Ultraflex S2 (Class C2FTS2).

Even if you plan to have your pavers professionally installed it is a good idea to be familiar with the process.

Here is a quick guide for installing JustPave in a variety of areas:

Directly On Grass
Directly On Gravel/Pebbles
With Sand/Cement Mortar on Hardcore
With Pedestals
With Tile Adhesive on Concrete Substrates

In all cases refer to professional advice and instruction for proper installation methods to maintain the long term integrity of the installed surfaces.

Installing JustPave Vitrified Pavers on Grass/Lawn

Installation on grass can be performed in two ways:

A) Direct: Dry set the paver on to grass leaving 4-5 cm wide joints to allow the grass to grow through. Results will be long lasting but stability of the surface will be subject to soil movements.
B) On Small Gravel Bases to Minimise Movement:

Remove the grass from the area underneath the JustPave Vitrified Paver Slab.
Dig out to 5cm deep in warm and dry climate, or deeper in cold or wet climates. • Compact the soil.
Fill the excavated area with gravel/aggregate (size 4-8 mm) or sand and compact it to create a solid base.
Dry set the JustPave Vitrified Paver directly on top of the compacted base.

Installing JustPave Vitrified Pavers on Sand

Remove the grass from the area underneath the JustPave Vitrified Paver Slab.
Dig out 5-7 cm deep in warm and dry climate, or deeper in cold or wet climates. Ensure the area is approx. 15cm wider than the finished installed surface.
Compact the soil.
Lay Geotextile permeable fabric on the compacted soil (if required for weed control). • Fill the excavated area with gravel/aggregate (size 4-8 mm) and compact it to create a minimum 2-3 cm solid base.
Fill with sand and compact the material to create a firm surface, allowing a 1.5-2° slope away from any building. Do not compact the pavers.
Install exterior edging restraints where necessary to minimise peripheral movement. • Space and dry set the JustPave Vitrified Paver directly on top of the compacted sand base, ensuring to leave a 4mm space between each one. Never install with paver to paver contact.
Level the pavers with necessary using a rubber mallet. Never compact the pavers with a vibrating plate. Simply fill the joints with sand to complete.

Installing JustPave Vitrified Pavers on Gravel/Pebbles

Remove the grass from the area underneath the JustPave Vitrified Paver Slab. • Dig 5 cm deep in warm and dry climate, or deeper in cold or wet climates.
Ensure the area is approx. 15cm wider than the finished installed surface.
Compact the soil.
Lay Geotextile permeable fabric on the compacted soil (if required for weed control).
Fill the excavated area with gravel/aggregate (size 4-8 mm) and compact it to create a minimum 2-3 cm solid base.
Install exterior edging restraints where necessary to minimise peripheral movement. • Dry set the JustPave Vitrified Paver directly on top of the compacted sand base.
If installing with wide joints, simply fill the space with decorative pebbles.

Installing JustPave Vitrified Pavers on a Mortar Bed

Remove the grass from the area underneath the JustPave Vitrified Paver Slab.
Dig 15 cm deep in warm and dry climate, or deeper in cold or wet climates.
Ensure the area is approx. 15cm wider than the finished installed surface.
Compact the soil.
Lay Geotextile permeable fabric on the compacted soil (if required for weed control).
Fill the excavated area with gravel/aggregate (size 4-8 mm) and compact it to create a minimum 10 cm solid base.
Install exterior edging restraints where necessary to minimise peripheral movement. • Blend a 4:1 mortar mix using sharp sand and ordinary cement. Avoid using building sand or white cement. • Shovel or trowel approx. 30mm bed of mortar and ripple to help spread once the paver is placed. It is important to maximise the contact between the mortar and paver (creating a solid bed and reducing air pockets beneath the surface). Only install one paver at a time ensuring the bed is wider than the paver. • Using a slurry primer and coating the back of each paver immediately prior to installation will help the product to bed in the mortar. • Use a rubber mallet to tap down the paver to remove any high/low spots and maximise the contact with mortar mix. Do not walk on for at least 24 hours.

Installing JustPave Vitrified Pavers on a Concrete Base with Tile Adhesive

Where there is likely to be persistent foot traffic or heavy loads from cars driving on the pavers it is recommended to install them with highly flexible exterior grade tile adhesive to ensure the long term integrity of the product. In this method the pavers are laid in the same manner as laying floor tiles inside the house:

The paver can be laid on a suitable pre-installed concrete base. This base should have had at least 3-4 weeks ‘drying out’ period after installation.
A suitable exterior grade highly flexible floor adhesive, such as Mapei Ultraflex S2 (Class C2FTS2), should be used to install the JustPave Vitrified Pavers. Always refer to the manufacturer’s technical instructions.
The adhesive should be spread evenly over the whole of the rigid base using a notched trowel.
The underside of the paver should be back-buttered with adhesive to create a bridging bond when the paver is laid (creating a solid bed and reducing air pockets beneath the surface).
The paver is then pressed down onto the adhesive and settled.
For installation on smaller concrete bases where thermal expansion will be minimal then use 4mm joints. On larger concrete bases seek advice on the need and use of movement control joint between the tile areas.

Installing JustPave Vitrified Pavers with Adjustable Pavers

Measure the total area to be paved to determine the number of pavers required and mark the intersections of the corners of each paver being installed to prepare a layout grid guide.
Position the first pedestal in one corner of the area and position subsequent pedestals along one wall edge. If necessary cut the bases of the pedestals along the scored lines to ensure the pedestals are as close as possible to the wall. Snap off any spacer tabs that are not required.
Place a second row of pedestals parallel to the first and carefully position the pavers with each corner resting on the top of a pedestal head and tightly butted against the spacer tabs.
Adjust the height of each pedestal to ensure each paver is level. • If extra support is required simply place an additional pedestal (with all tabs removed) under the centre of the paver.

Cutting JustPave Vitrified Pavers

Vitrified Pavers should be cut using a water cooled, dust suppressing saw fitted with a diamond tipped blade specifically made for cutting porcelain pavers slabs. This saw can be either;
A bench power wet-saw
A masonry cutting power saw with water feed
The cutting blade should always be water suppressed whenever cutting the vitrified paver to control dust and cool the blade. The diamond tipped blade should have a full interrupted circular edge and have no gaps.
Never cut vitrified pavers with a fibre blade.
Always use a good quality diamond blade. Such is the compact hardness of vitrified pavers that a blunt or worn diamond blade is likely to create unattractive shelling or oystering along the cut edges.
Paving installers unfamiliar with working with vitrified paving should practice cutting with the material prior to carrying out final installations.

Joint Filling Information

When pavers are installed in sand, mortar or tile adhesive you may fill the 4 mm joints with:

Traditional Sand Dry traditional sand is swept into the open joints until they are completely filled. Excess sand should be swept off of the pavers. Please note mind that sand joints may need to be occasionally topped up or re-sanded over tile as wind and rain can cause some erosion.
Cement Blended Sand Dry cement blended sand (typical 3 parts sand to 1 part cement) is swept into the open joints until they are completely filled. It is essential that excess cement blended sand is swept off the pavers (blowers can also be used for final dust removal). Please note any residual dust or sand remaining on the surface may make the pavers difficult to keep clean after installation. After joints are full and the surface is clean the pavers can be misted with water to activate the cement and cure/harden the mixture. For final clean use Fila Deterdek.
Ready Mixed Jointing Compound When installing pavers on a compacted base you can use ready mixed resinbound jointing compounds such as ‘Joint-It Simple’ to provide a maintenance free, long lasting professional finish. With working times of up to four hours ready mixed jointing compounds are easy to use, cement-free formulations designed for use in all weathers. Simply brush the compound diagonally across the paving joints working it in until they are full. Remove any excess jointing compound and sweep the pavers with a soft brush to clean the surface. Completed installations should not be walked on for at least 24 hours and should also be protected from rain, frost and freezing temperatures during this time. Residual jointing dust can be simply brushed off after 24 hours.
Flexible Tile Grout If installing pavers on a concrete base using tile adhesive it is advisable to use flexible exterior grade tile grout such as Mapei Ultracolour Grout in the joints. In warm weather avoid working in direct sunlight. Protect the area from rain, frost and freezing temperatures for several days after grouting. Never allow grout to remain on the surface of the pavers for an extended length of time before completing the initial cleaning. Make sure that all tiles are thoroughly cleaned with Fila Deterdek to prevent residual grout remaining on the surface.
