How It Works
RotGuard™ is a dual-layer, self-adhesive membrane that forms a durable barrier around the post’s ground-contact zone. Apply before installation to protect against rot, moisture ingress, and fungal attack.
Choose RotGuard™ to save time, money, and stress, and ensure your posts stand strong for decades. Do it once. Do it right.
What are Fence Post Wraps?
Wooden fence posts are especially vulnerable to rot and decay at the ground line — the critical zone where moisture, oxygen, and soil microbes meet.
Fence post wraps, like RotGuard™, provide an affordable and highly effective way to protect this area. By creating a durable, water-resistant barrier, they block moisture and oxygen that feed fungal growth, helping to prevent ground-line rot and extend the life of your posts.
Why Choose Rotguard™? |
RotGuard™ offers superior protection against ground-line rot, significantly extending the lifespan of wooden posts for decades.
Its advanced dual-layer design features a tough polyethylene outer layer combined with a self-adhesive, water-resistant inner membrane, creating a reliable barrier that stops moisture and fungal decay at the most vulnerable point of your post.
RotGuard™ is quick and easy to install with no torch, heat gun, or special tools required, making it an excellent choice for both DIY homeowners and professional contractors.
Cost-effective, versatile across various post types, and environmentally friendly, RotGuard™ reduces timber waste and minimizes the need for harsh chemical treatments in the soil.
It’s a smart, sustainable investment for stronger, longer-lasting fences and outdoor structures.

Dual-Layer Construction

Frequently Asked Questions |
How long does RotGuard™ last?
RotGuard™ is engineered from industrial-grade membrane materials that have been used in critical waterproofing applications for decades. When properly installed, it’s backed by a 25-Year Warranty against ground-line rot.
Can you use RotGuard™ on concrete or metal posts?
RotGuard™ is specifically designed for wooden posts but can also be used on metal posts, especially in environments with acidic or contaminated soil where corrosion is a concern. It is not typically needed for concrete posts.
Why doesn’t RotGuard™ cover the bottom of the post?
RotGuard™ is designed to protect the critical ground-line zone, typically the top 6–8 inches below grade and slightly above grade. Below that depth, there’s not enough oxygen or favorable temperature for rot or corrosion to occur, so additional coverage isn’t necessary.
Do I need a torch or heat gun to install RotGuard™?
No! RotGuard™ uses a self-adhesive membrane that requires no heat, torching, or special tools. Simply peel, wrap, overlap, and press firmly to install.
Can I use RotGuard™ on posts that are already in the ground?
RotGuard™ must be applied before installation, while the post is still out of the ground. It wraps directly around the post to create a protective barrier before burial.
