Paving Installation Advice

These are very basic, yet essential pointers on the installation of SmartStone cobbles and flagstones.

Read through these simple points and become more aware of what an installer should and should not do when installing your SmartStone paving.

We do not recommend that plastic sheeting be installed beneath paving

Weeds do not grow from beneath paving. They grow from seeds that enter the paving from the top, via bird droppings, the wind, etc. Plastic sheeting underneath paving creates serious structural problems, among others.

The sub-base, or earth beneath the paving, should be very well compacted

We recommend the use of a mechanical roller for this purpose, rather than just a plate compactor. While we know that this seldom actually happens, if installation is done at a new home, where a lot of digging has been done, you must insist that soil compaction be done using a roller like a Bomag 90.

Prior to starting installation, determine the laying patterns

The installer should discuss with you the lines and directions in which the pavers will be packed, as well as possible laying patterns. Make sure you find it aesthetically pleasing and practical.

Ensure the contractor allows for levels and water run-off

Ask about the plans for drainage and look at the surrounding natural slopes.

The base of flagstones and tiles should be wet before they are seated

Dry pavers will absorb the moisture in the bedding material, causing it to dry out too quickly.

Grouting should be done according to this method

  • The grouting of SmartStone cobbles should be done with wet slurry and not dry cement sprayed with water.
  • Grouting of flagstones should also be done with SmartStone-approved grouting. (Details are available from your SmartStone branch.)
  • The grouting of flagstones should be “pointed”.
  • Tiles and flagstones should be moist when grouted.
  • Plaster key should be added to the grouting mix.
  • Flagstones should be covered with plastic sheets for four to five days after installation in order to prevent grouting drying too quickly. If it dries too quickly it will crack within a year or two after installation.

Wash grout and cement off immediately

Ensure grouting and cement are washed off immediately to avoid cement staining on pavers. A hand sponge should be used for this purpose, rather than brooms, etc.

The contractor should work in sections

If the contractor tries to work over too big an area, it could result in complete site failure. All work should therefore be done systematically, in small sections and completed per section, before moving on to the following phase of installation.

Do not transport SmartStone products in wheelbarrows

SmartStone products should not be dumped and transported in wheelbarrows. like normal bricks. The product will get damaged. If contractors use wheelbarrows, they should be lined with blankets. Most importantly, SmartStone is made by hand and should also be packed and unpacked by hand.

Driving and walking on SmartStone

Do not drive on a new SmartStone driveway for seven days or walk on any SmartStone paving for five days after installation.

Paving curing

Paving should be allowed to cure thoroughly before sealing. We recommend that you wait six months before sealing paving.
