Frequently Asked Questions (FAQs)

1. Can you waterproof fence posts?

Pour waterproofing sealant into a bucket, immersing the end of the post (which will be buried below ground) into the sealant. Allow the post to sit in the bucket of sealant overnight, then leave to air dry.

2. How do I keep my fence post from rotting?

Applying a seal or stain to your wooden fence can help provide an additional level of protection against rot. You can choose to use a water repellent sealant to your wood to help keep rot-causing moisture out from your fences.

3. What type of fence post lasts the longest?

DuraPost is stronger than both concrete and timber fence posts and is guaranteed to last up to 25 years. Made from galvanised steel, DuraPost doesn't rot, split, warp, crack or chip and can even withstand winds of up to 110mph! It's a no brainer if you ask us.

4. What can I use for fence posts instead of concrete?

Gravel can be a great alternative to using concrete, and it does away with any drainage problems either underground or around the base. However, the success of gravel as a post setting depends upon the soil. It doesn't work in loose or sandy soils, but is ideal for heavy, clay-type dirt.
