How To Install Outdoor Porcelain Tiles: Laying Porcelain Pavers on Pedestals

The popularity of Porcea Stone outdoor porcelain pavers is rising steadily. That’s because our products are not only durable and beautiful but also boast weather-resistant properties and are easy to install. Along with that, they are consistent in both texture and colour.

Our collection is available in 2 cm and 3 cm thickness, making them far thicker than your regular porcelain tile. This means that you can use our outdoor porcelain on your patio, deck, driveway, backyard, pathway, balcony, and pool area. Their unyielding strength makes them the perfect material to use for both light and high traffic areas. Likewise, you will be able to install our products in numerous ways, including the following:

  • Sand or gravel
  • Concrete and mortar
  • Raised on pedestals
  • Lay on grass

All of these installation methods come with their own benefits. In this article on how to install outdoor porcelain tiles, we will show you how to lay porcelain pavers on pedestals. 

Pedestal System Overview

The pedestal system technology has been around for many years, dating as far back as the Etruscan and Roman civilizations. It is used both inside and outside of buildings to provide solutions to essential construction problems. One of those is to prevent water stagnation on outdoor floors that are exposed to bad weather as it can seriously damage the structures over time.

Other problems the raised floor technology solves are direct exposure to extreme and natural temperature changes and structural movements. These produce substantial tensions in coatings. If they are attached to the support rigidly with minimum dilatation freedom, it may lead to crack formation. Moreover, the sealing of the coatings is tested by strong wind gusts and extreme weather conditions. This means that it will need specialized tools specifically made to ensure utmost safety and stability. 

Meanwhile, indoor floors require certain solutions for special environments. These include commercial buildings or technical premises that enable the installation of plants and pipes beneath the floor. The floors have to be easy to inspect, safe, and aesthetically pleasing.

Difference Between Adjustable and Fixed-Height Pedestals

The adjustable pedestal system typically consists of a set of top pedestal units and a threaded base. It also comes with variable joint spacer tabs, which you can connect with fixed-height pedestals and threaded extender units. This type of pedestal is intended for wood tiles and architectural pavers.

On the other hand, the fixed-height pedestal system is composed of round fixed height pedestals. Likewise, it comes with integrated joint spacer tabs and round flexible shims. It is meant for architectural pavers, such as outdoor porcelain tiles to provide a loose-laid, open joint paver installation.

Steps on Laying Porcelain Pavers on Pedestals

Step 1: 

Make sure your substrate is clean and smooth. For proper drainage, it should have about a 2-degree slope.

Step 2:

Use chalk to lay out the placement of your pavers. Doing so can help you find the best location for placing your pedestal supports. Make sure to establish the border and corner supports accordingly. 

Keep in mind that your supports will have built-in spacers to allow a 3/16-inch gap between your porcelain pavers.

Step 3:

Put the pedestals along the perimeter and the intersections where you will lay the paving stones.

Step 4:

Lay your Porca Stone outdoor porcelain pavers on top of the pedestal, ensuring that the materials are level against the spacers.

Step 5:

If you encounter an issue with the alignment, the pedestal system can provide you with shims, slope correctors, and adjustable pedestals. These will enable you to make adjustments.

Wind Uplift Solution For For Laying Outdoor Porcelain Tiles On Pedestals

Plate lifting due to the wind is one of the main concerns of residential and commercial projects with pedestal systems. Fortunately, there are products on the market today equipped with windproof technology that is permanent, safe, and cost-effective. 

With this technology, the supports and flooring plates will have a stable bond between them. Moreover, these pedestal systems have metal clips inserted into the spacer fins of the supports, blocking the flooring plates. This will firmly attach the plates and supports together. As a result, it forces more resistance to the sucking power of the wind as the flooring becomes one with the plates and the entire system.

The other common solution is to go with a 30mm Porcea Stone paver which adds 50% to the weight of the tile and also the strength, thereby significantly minimizing the potential for wind uplift. All of these solutions should always be reviewed by structural engineers and are purely for indicative and guidance purposes.

Porcelain Tiles Installation Do’s and Don’ts to Keep in Mind

  • Only utilize a wet saw with a blade particularly designed for porcelain when cutting your pavers.
  • Use spacers to make sure your outdoor porcelain pavers have a distance of at least 3/16-inch between them for proper drainage.
  • Place your pavers on a slope to make sure they are drained properly. As mentioned, the recommended slope is 2 degrees. However, this may vary depending on the area and location where you will install the pavers. 
  • Compact the substrate thoroughly to prevent movement or gapping.
  • Avoid damaging your beautiful porcelain pavers by making sure to read installation instructions beforehand.
  • Pedestals are commonly used if there are conduits or pipes running along the base of the substrate, primarily used for rooftop applications.
  • Using 30mm Porcea Stone pavers can help eliminate concerns with wind uplift and breakage of tiles from impact.
  • Don’t hesitate to contact our team when you see yourself stuck in a process or if you are unsure how to go about the installation.
