Paving Pedestal Installation

How to install pedestals for porcelain paving

Raised Paving Installation

A lightweight, convenient system, with slabs which can be lifted off for inspection. It improves thermal insulation and is able to accommodate pipes and cables.

Pedestal Arrangement

The pedestal arrangement will vary depending on the dimensions of your paving tiles. For example 60x60 tiles only need supporting on every corner, whereas 80x80 require a pedestal in the centre of each tile to distribute weight

Installing a pedestal in a tight corner

In corners or along edges where the top of the pedestal cannot fully support the paving slab, you can turn the pedestal upside down.

What you need

  • Paving slabs
  • Pedestals
  • Spirit level
  • Tape measure

Installation Steps

Step 1

Raised paving installation clearing area
Start off by clearing the proposed paving area. Measure the width and length of the area in order to calculate the number of pedestals needed.

Step 2

Raised paving installation substrate pitch
The substrate must be appropriately waterproofed and have a suitable pitch (1.5-2%) with systems for water drainage.

Step 3

Raised paving installation lay pedestals
Lay the pedestals, ensuring the correct slope for drainage using a spirit level and pedestal slope correctors.

Step 4

Raised paving installation spacers
Pedestals should be arranged with the aid of a spacer which leaves a joint of 2-4 mm between tiles. The open gap created allows rainwater to drain into the cavity underneath.
