Clean concrete base of any dirt or dust; <br>2. Moisten concrete base surface with a light spray of water. Pour a 1:1 cement and fine sand: water slurry mix (bond coat) over the concrete base prior to placing bedding mortar. <br>3. Mix thoroughly 3:1 sand:cement by volume as a semi-dry mix mortar, ensuring a uniform mix and sufficient strength (min 10 MPa at seven (7) days). Prior to mixing, check sand is moist by squeezing a handful and ensuring the sand maintains its shape. Water may be added in the specified proportions to impart to the mix with sufficient consistency. Only sufficient bedding mix should be prepared and laid to enable the laying operation to be completed within a reasonable time. Refer to 5.3.5 for more details on mortar and slurry material. <br>4. Place semi-dry mix mortar over slurry coat. Installation of mortar mix to be 10 to 15% higher than required levels (or higher as necessary) prior to compaction of stone pavers; <br>5. Apply pre-mixed 1:1 cement water slurry mix to cover area of mortar to be paved. No delay in laying of pavers after application of the cement slurry; <br>6. Paving units shall be laid surface dry on the slurry coated mortar bedding course with a joint width of 1 to 3mm between adjacent pavers; <br>7. Tamp down paving units into position ensuring full contact with the mortar bed with minimum deviation between edges of adjacent pavers; <br>8. Check individual paver units for correct installation as work proceeds. Where stone pavers do not align properly, are loose, drummy or rock, remove non-compliant pavers, remove mortar bed (full depth) and repeat mortar bed and paver installation procedure again <br>

Trial mixes of mortar bedding material must be carried out and tested before the commencement of the Works to adequately select a mix that meets the strength requirement. Strength-testing reports shall be available on request to the City’s Representative for approval.<br>2. All mortar for the pavers is to comply with AS 3700 Masonry Structures, in particular Sections 4, 5 and 10, and is to be a 3:1 (river sand) cement. A slurry mix is to be applied on top of this bedding, with a latex additive before laying of pavers to increase bond and compressive strength. The mortar minimum thickness shall be 25 mm and the maximum 30 mm. The amount of mix shall not exceed the quantity required to lay pavers within 45 to 60 minutes, depending on climate conditions.<br>3. All components shall be measured by means of calibrated containers. The minimum compressive strength of the mortar mix shall be no less than 10 MPa at seven (7) days. Also refer to Subsection 5.4.7 <br>4. The bonding slurry shall consist of one (1) part fine-washed sand and six (6) parts Portland Type A cement by volume mixed by hand or mixer while adding water to ensure a smooth, homogenous consistency, free of lumps. <br>5.
