How to Lay paving Flags

This guide is not a complete working guide to laying paving stone.

You should always conatct a professional landscpaing company or paving specialists first before any work commences.

This is a brief guide to explain the laying of paving flags.

Laying paving stone.

Reclaimed paving stones or flags such as reclaimed York stone are extremely heavy. Make sure you have the appropriate tools & help on site to manage these heavy paving flags.

Prepare site: Dig out the area that is to be paved; drainage must be away from any abutting buildings. A fall of 1:100 should suit most projects.

Put Down Subbase: It is recommended a sub base of 75mm – 100mm. Once material has been laid, compact the subbase using a Wacker – plate creating a firm surface.

Lay the paving slabs:

A full bed of wet mortar is recommended to allow you to adjust paving flags into position. A mortar mix that is firm and wet is better than damp mortar.

Natural stone paving or reclaimed paving can have variations in thickness, so the correct mix will make positioning these much easier on site.

Natural stone has natural colour variations, if you are laying a large area, it is best practice to select the stones that are to be laid, not just the closet paver to your hand! This makes a more natural looking blended finished job.

 When laying natural sandstone paving ensure you are laying the flags the correct way up! When using natural stone cut paving the edges are straight, the underside is calibrated making it obvious as to which side faces up.

Tap flags into positions:

Using a rubber mallet carefully tap the flags into position checking the levels in each direction.

Space to leave for pointing:

10 – 15mm between each slab for pointing.

Pointing patio paving flags:

A Polymer base jointing compound creates a strong joint that allows surface water to drain through.

At Wilsons we always recommend using a professional landscaping company or paving specialist, such as Garden Innovations.
