Product Information

Full details

These B&Q wooden fence posts are engineered for homeowners and landscapers seeking a durable, high-stability solution for perimeter fencing and garden structures. Providing exceptional support due to their 3000mm length, they are ideal for areas prone to high winds or soft soil, though their significant weight requires a two-person installation effort to ensure safe handling and proper alignment.

FAQs

Do these posts need painting?

They are pressure-treated, so they do not require immediate treatment; however, you can apply a wood stain or paint after a few months once the timber has dried out.

Can I cut these to size?

Yes, but ensure you treat any exposed cut ends with an end-grain preservative to maintain the integrity of the pressure treatment.

Are these posts suitable for concrete installation?

Yes, they are designed to be set in post-fixing concrete for maximum stability.

What is the total length of each post?

Each post is exactly 3000mm (3 meters) in length.

How many posts are in the pack?

This pack contains 10 individual wooden fence posts.

Troubleshooting

Post is leaning after installation

The hole was likely not deep enough or the backfill concrete was insufficient; re-brace the post and add additional concrete support.

Moisture accumulation at the top

Install a protective post cap or a metal finial to shed rainwater and seal the end grain.

Pros and Cons

Pros

  • Superior resistance to moisture and rot
  • High structural stability for tall or heavy fencing
  • Generous length allows for deep, frost-proof installation
  • Professional finish suitable for modern garden designs

Cons

  • Heavy weight requires multiple people for safe installation
  • Not intended for non-ground contact applications
  • Requires proper cutting tools if shortening is needed

Setup, Compatibility & Care

For installation, dig holes to a depth of at least 750-900mm using a post-hole digger. Ensure the bottom of the hole contains a layer of gravel to promote drainage, which prevents the base of the post from sitting in standing water. Once the post is leveled, secure it with concrete or post-fixing mix. While the posts are pressure-treated, it is recommended to apply a wood preservative to any cut ends if you decide to trim the post height, as exposed raw timber is vulnerable to moisture. Regularly inspect the post bases after heavy storms for signs of movement and check that caps are secure to keep the end grain dry.
