Concrete Post Support – Heavy Duty – Outdoor Fencing

Product Overview

This heavy-duty concrete in post support system is designed specifically for 100mm × 100mm square timber posts. Engineered for secure installation, it provides a stable and durable base for fencing, decking, and structural outdoor timber applications. Made from galvanized steel, it ensures exceptional strength and corrosion resistance.

The innovative design features a welded steel box section that grips the post firmly above ground level, preventing direct contact with concrete and reducing the risk of rot. The below-ground spike section embeds directly into a concrete base, ensuring a rigid and permanent fixing even under high lateral load.

Features & Benefits

• Strong foundation support: Welded steel construction ensures solid anchoring in concrete for long-term stability.
• Corrosion resistant: Hot-dip galvanized coating protects against rust and environmental exposure.
• Rot prevention: Lifts timber post clear of the ground, reducing moisture absorption and decay.
• Secure grip: Box section holds post firmly in place with twin bolt or clamp fixing.
• Permanent installation: Designed for embedding in concrete foundations for high-strength structural support.
• Size: 100mm × 100mm internal box section suitable for standard 4-inch square timber posts.

Applications

• Fence post installation: Provides a stable, rot-resistant base for timber fencing.
• Gate posts: Ideal for supporting heavy or frequently used gates.

Installation Guidance

• Preparation: Excavate a hole to the required depth and fill partially with a wet concrete mix.
• Positioning: Insert the spike section into the concrete and align with post line before setting.
• Levelling: Ensure the post holder section remains vertical while concrete sets.
• Post insertion: Once cured, insert the timber post and tighten clamping bolts or screws.
• Final check: Confirm the post is square, plumb, and securely fixed before loading.
