GUIDELINES FOR LAYING TRAVERTINE PAVERS
We recommend our pavers to be laid and grouted by a licensed paviour
Travertine pavers can be laid on a compacted ROAD-BASE sub base or on SCREED BED.*
Installation on ROAD-BASE sub base
|
Recommended road-base sub base thickness: |
75 - 100 mm |
|
Recommended coarse paving sand thickness: |
20 - 40 mm |
|
Recommended gap between pavers: |
3 - 4 mm |
We recommend applying water repellent penetrating sealant to the pavers before filling the gaps (Pavers can be pre-sealed if wanted)
After joints are filled with dried material, the pavement is ready to receive foot traffic.
Installation on SCREED BED
|
Recommended screed bed thickness over concrete slab: |
20+ mm |
|
Recommended cement to sand mix in screed: |
1 to 4 |
|
|
* |
Sprinkle cement dust over screed bed. |
|
|
* |
Wet cement dust (sponge or a watering can with fine sprinkle head can be used) |
|
|
* |
Place the pavers. No need to wet or seal the back of the pavers. |
|
|
* |
Tamp the pavers by using rubber mallet. |
|
|
* |
Use expansion joints (10-15mm) every 4 - 5m. Expansion joints need to be incorporated over existing expansion joints, around corners, next to fixed walls etc. |
|
|
* |
Allow paving and bed to dry out before grouting. |
|
|
* |
We recommend applying water repellent seal to the pavers before grouting. (Sealing can be done before laying if wanted) |
|
|
* |
Grout the pavers. If wet grout is used sponge off grout from pavers’ surface immediately. |
Grouting
If required the surface of pavers can be filled with grout.
Recommend to use washed beach sand and off-white cement
Recommended cement to sand mix in grout: 1 to 3
|
|
* |
If required, after grout hardened, light acid wash can be used. Allow acid to sit for 5 minutes but not to dry. Rinse off with pressure wash. Testing it in an inconspicuous area first is recommended. |
Recommended dilution rate Phosphoric acid to warm water: 1 to 15
|
|
* |
Allow paving and grout to dry out completely then apply a final coat of penetrating sealant. sealer. |
|
|
* |
After sealing the pavement is ready to receive foot traffic. |
Maintenance and Cleaning
Penetrating sealant will make the maintenance and cleaning easier. Depending on the type of stain there are different stone cleaning products available on the market.
* If pavers are to be glued down they must be put on a flexible based adhesive.
