For commercial areas the expansion and control joints should be designed into the project by the engineering team

Please see iPave’s Technical Specifications for expansion and contraction test results.

For domestic projects as a guide iPave suggest the use of flexible expansion joints at intervals of 4 metre in each direction, around all walls and colums, as well as over any construction joints in the sub-slab.

These expansion joints should be left clean to the full depth of the paver and bedding and filled with an appropriate flexible joint filler like Silicone in a matching clolour.

Sand Bedding Over Concrete

The concrete slab should be designed for the required application i.e domestic driveway, commercial heavy duty driveway/roadway, path etc and should be recessed approximately 30mm plus the thickness of the paver below the required finished height and accurate to drainage falls. In the case of a domestic installation as a guide100mm of reinforced concrete with a fine wood float finish should be sufficient.

Spread and screed approximately 30mm of coarse bedding sand over the entire concrete area to the required level (approximately the depth of the paver less 5mm for settlement below the finished height).

Place the full pavers onto the coarse sand bedding to the desired pattern, taking care to keep the lines straight by checking each row with a string line, while only walking on the pavers, do not disturb the sand screed by walking on it as this will result in an uneven finish on the surface.Ensure the pavers are leveled as you go.

Once the full pavers have been laid in the given area measure and fit those pavers that require cutting (see separate cutting instructions)

iPave recommends you use either a full or half paver around the perimiter as a border to contain and keep the cut pieces from the edge

( see separate under set out )

Once the full pavers have been laid remove the border pavers and the sand beneath them, re-fitting the border pavers by wet bedding them with (3:1 sand and cement) mortar. (see separate under edge restraints )

Sweep the joints full with dry joint filling sand (see separate under grouting) and retain the edges (see separate under edge restraints)

If you feel the pavers require compaction then (see separate under compaction)

Due to potential sub-base and bedding sand wash out this laying method is not recommended on a slope over 5 degrees

Motar/Glue Over Concrete

The concrete slab should be designed for the required application i.e domestic driveway, commercial heavy duty driveway/roadway, path etc and should be recessed approximately (25mm for mortar) (5mm for glue) plus the thickness of the paver below the required finished height and accurate to drainage falls. In the case of a domestic installation as a guide100mm of reinforced concrete with a fine wood float finish should be sufficient.

Mortar bedding use clean washed sand and cement at a ratio of 3 parts sand to 1 part cement thoroughly mixed screeded accurate to falls to a depth of approximately 25mm,dust the surface of the mortar liberally with dry neat cement allowing the moisture from the mortar to wet the neat cement.Do not spread mor mortar than can be covered by paving before it commences to set

iPave recommends you use either a full or half paver around the perimiter as a border to contain and keep the cut pieces from the edge

( see separate under set out )

Place the pavers in the required pattern, taking care to keep the lines straight by checking each row with a string line and fitting the cut pieces as you go, untill the area is paved.

Ensure all excess cement and mortar is removed from the surface of the paver before it commences to set

Remove any surplus bedding material at the completion of each days work

Grouting can commence after 24 hours in eithe rthe rigid or flexible method (see separate under grouting)

iPave do not recommend this method of installation to the handyman

Adhesive bedding use a good quality flexible adhesive such as Ready Fix Elasta Grip, mix according to the instructions, notch the adhesive out with a 12mmx12mm notch trowel (do not spread more adhesive than be covered before it commences to skin over) approximately 1m2 at a time.
