Does this look familiar to you? Broken fence, rotten, wind damaged fence posts? You may want to repair it or save time and effort building a brand new fence. In both instances, Sika Post Fix is the product that fundamentally changes the way people can install or repair their fence.
Sika Post Fix is a two-part, pre-proportioned polyurethane resin which when mixed produces an expanding foam. It has been specifically formulated and packaged to provide a lightweight, mix-in-the-bag, fast-setting and high-strength backfill for wooden, PVC and steel in-ground supports. Sika Post Fix is based on Sika’s proven foam technology and designed for easy, convenient and quick support of many types of post.

Let’s talk performance…
Sika® Post Fix is solid as Concrete. Thanks to its ability to expand in all directions in the hole and adhere to virtually anything in the ground (rocks, roots, etc.), Sika® Post Fix offers an excellent pull-off resistance and will perform equally as well as — if not better than — concrete. For replacing posts, it is far easier to work with than concrete.

Sika® Post Fix yield
Here’s a quick and easy tool to help you calculate the number of bags you will require for your project.
comparison vs concrete
Sika® Post Fix: One 979 mL pouch yields approx. 20 L (0.7 ft3) of expanded foam. Let’s take a standard 25-post fence job, your project will require:
- 50 bags of concrete mix (count 2 bags of concrete mix per post)
- 25 posts x 60 kg (2 x 30 kg/post) which adds up to 1.5 ton of concrete mix
- Ability to haul
Before you Start
Some useful tips for a successful fence-building or repair project:
- Check your local Building Code for frost depth in your area (it will determine the depth of the holes)
- Read the product data sheet and directions on the packaging before starting
- Product temperature: Sika® Post Fix temperature must be between 18 – 25°C for at least 2 hours before using (keep in mind that the average temperature of a garage slab is 14°C, if your material is stored directly on the ground, it will be at the same temperature… 14°C! notice that 4 degrees make the whole difference in terms of product performance)
- Make sure the holes are free of standing water: If there is standing water in the hole, backfill partially with soil or gravel until water is no longer visible or pump the water out
- Respect the 20-second mixing time
- Don’t move the posts beyond the first 10 seconds following the initial pour (don’t hesitate to use a bracing device to immobilize the post in the hole)
- Be prepared to work fast: Wear your safety gear (gloves and safety goggles), have the post already positioned in the hole, have all your tools ready and avoid distractions: the product works quickly once you’ve started the mixing process.
