Sika Post Fix is a great alternative to instant concrete for simple jobs like planting a post.
The expanding polyurethane resin rapidly fills the hole around the post in just a few seconds and will set in just 3 minutes.
Any excess material that expands beyond the edge of the hole can be cut away with a sharp knife.
The resin will reach full strength in just 2 hours.
Each 33 oz. bag costs around $12 at your local hardware store and effectively replaces two 50 lb bags of concrete mix.
