MOT Type 1 Aggregate – Crushed Limestone/Granite – Driveways & Patios

Product Overview

The Professional Rot Protector Sleeve is designed for 75mm-100mm square fence posts. This heat-shrink post protection sleeve effectively prevents ground-line rot and decay in timber fence posts. It features a dual-layer barrier system with a thermoplastic outer layer and a bitumen-based inner liner, creating a watertight and airtight seal at the critical ground-contact zone.

Upon heating, the sleeve shrinks tightly around the post surface, bonding permanently to provide long-term protection against rot, fungi, and bacterial degradation. It is compatible with both treated and untreated timber posts, significantly extending the service life of fencing, gate, and decking structures.

Features & Benefits

• Dual-layer protection: Combines a heat-shrink thermoplastic sleeve with a bitumen sealant lining for a permanent barrier.
• Prevents rot: Seals out moisture and air at ground level, eliminating primary causes of post decay.
• Long-term performance: Proven to extend timber post life by more than 20 years in typical outdoor conditions.
• Universal fit: Suitable for sawn or planed 75mm-100mm square fence posts.
• Easy application: Can be applied with a standard heat gun or blowtorch, bonding directly to the timber surface.
• Maintenance-free: Provides lasting protection without the need for re-treatment or chemical reapplication.

Applications

• Fencing installations: Protects timber posts used in garden, agricultural, or perimeter fencing.
• Gate posts: Prevents decay at ground level in larger timber supports.
• Decking and pergolas: Used on structural posts in outdoor landscaping applications.
• Timber structures: Suitable for any buried or ground-contact timber exposed to moisture.

Installation Guidance

• Preparation: Ensure post surface is clean, dry, and free from dirt or treatment residue.
• Positioning: Slide sleeve over the post so it sits at the intended ground line position.
• Heating: Apply even heat with a blowtorch or heat gun until the sleeve fully shrinks and the adhesive bitumen flows.
• Bonding: Allow the sleeve to cool and bond firmly to the post before installation in the ground.
• Final check: Confirm the sleeve forms a continuous seal with no visible gaps or air pockets.
