Fast 2K Fence Post Backfill: A Better Alternative to Traditional Concrete

PineRiver2.jpg

Setting fence posts is normally a long, time consuming job. Mixing the concrete, getting the moisture levels correct, then waiting for it to cure all take time. A fence is really only as strong as what’s holding the post, though, which makes the backfill a very important part of the installation.

Fast 2K fence post backfill is a fast, easy to use alternative to traditional concrete that solves many of concrete’s issues. Not only does it save time, it can help to preserve your wooden posts for longer as well.

Issues with Concrete

Concrete has been around for a long time, so most people are familiar with the way it works. You add water and mix together to begin the chemical hydration process. Then you pour it in the hole with the fence post, cover with dirt and wait for it to harden and cure. It’s a fairly simple process, however in practice it’s a lot of work. Mixing concrete is strenuous labor for one. Not only does it take time and manpower to mix and pour, but it also takes a day (at least) to cure before you can really start building the fence. Plus if your mixture is off, say you have too much or too little water, the structural integrity of the entire fence can be compromised.

Another cautionary detail of concrete, especially when installing wood posts, is that it absorbs moisture. So while your fence may look good from above, moisture may be seeping into the concrete below and penetrating the wood posts which can cause deterioration over time.

Additionally, concrete doesn’t set if it’s too cold, which makes limits the building season significantly in areas that experience cold winters.

Finally, from an inventory standpoint, concrete bags are large, heavy and easily torn. So not only does it take up a lot of valuable real estate in your yard, the risk of losing money from damaged bags is actually quite high.

When you break it down, there are a lot of strikes against concrete which begs the question, why is it still so widely used? One answer, and arguably the truest answer, is because builders are used to it and not eager to change. There’s nothing wrong with being comfortable with what you know, however, if comfort stands in the way of progress and the ability to work faster and do more jobs, than maybe it’s time to step outside of that comfort zone and accept innovation.

Fast 2K as an Alternative to Concrete

Fast 2K is a backfill developed as a better alternative to concrete, particularly for setting fence posts. It mixes in 30 seconds and doesn’t require water. No more lugging water to a jobsite and spending time measuring components to make sure your mixture is right. Plus, Fast 2K sets posts in as a little as 5 minutes, so you can start building the rest of the fence almost immediately, allowing you to finish an entire job in a single day!

Fast 2K doesn’t need as much space around the post as concrete. So, the holes you dig for your fence posts can be smaller, which is yet another time saver. In fact, the less space around the fence post, the better. So, a 4x4 fence post will only need a 6-inch diameter hole. With these smaller sized holes, the installation can proceed far more quickly. This smaller hole diameter can also mean that other installations, such as mailbox or sign posts, won’t require the amount of space they would with concrete, so you can fit them into tighter spaces or areas where the post may not have been able to fit previously.

The material also cures quickly, so you can move onto the next phase of the fencing project in a fraction of the time that concrete would require. Once it’s cured, it’s incredibly strong and waterproof, able to withstand up to 750 lbs of lateral force without the post breaking. That’s much stronger than concrete in the same scenario, and it’s also stronger than tamped soil as well.

Fast 2K does not absorb water, so there’s no risk to wooden fence posts; your fence posts will now last longer, so you can get more time out of the fence.

The material is also super light; one 2lb back of Fast 2K will replace 2, 50lb bags of concrete. This makes moving the fill and getting to the job site much faster. No heavy machinery, wheelbarrows, or an ability to lift 50lbs at a time is required. And it’ll take up a lot less space in your yard to store.

Unlike concrete, which would require a saw or Dremel to cut and level once it’s poured, Fast 2K can be cut with a utility knife. The material can even bond with itself, unlike concrete, so if you pour too little or decide to add on to your installation later, you can add more without causing a structural weakness.

Fast 2K makes a great alternative to concrete for filling setting fence posts, but it has other applications as well. It can also be used to fill holes drilled into concrete, such as bike racks, picnic tables, mailboxes, and more.

Get a Better Backfill

While concrete definitely has its uses, it’s not the only – or the best – option to use for backfilling posts. Fast 2K is lighter, easier to use, takes up less space, and is stronger and waterproof once it’s cured. Using Fast 2K will make your projects come together faster, with less degree of error, and the finished results will be set up to last longer too. Making the switch from traditional concrete to newer, more versatile Fast 2K for your post backfill is a step in the right direction and a great way to increase your productivity.
