What Is Post Tensioning System?

Over the years, we’ve come to admire the majestic structures built worldwide. Be it a skyscraper, a towering bridge or a coliseum, we’ve often wondered just how it is possible to build such huge and heavy buildings.

A lot of historical and modern structures rely on post tensioning for a strong foundation. But what is this system exactly and how does it benefit all these massive constructions?


Post tensioning is the process of incorporating prestressed concrete to the construction materials. Prestressing is done by strengthening the materials internally in order to withstand the external pressure/weight, which is called “service” load.

A visual representation would be threading a concrete with a series of steel bars, much like a thread or string going through a bead.


The main purpose of post tensioning is to provide structures strength in both compressive and tensile stress, which means at any given time, the structure should hold well.


Post tensioning has been around for ages. In fact, it’s believed to be introduced by Eugene Fryssinet back in 1933 in France when a marine terminal was being built. It wasn’t long until the method reached the U.S in 1950 and was incorporated into building the Walnut Lane Bridge.

Over the years, the method has been developed and has well been utilized for residential spaces as well.


There are a lot of components that make up a complete post tensioning system. Here they are:

Tendons – these refer to one or more series of steel bars that go into the concrete. It could either be a high steel bar or high steel strand that are all ASTM-tested.

  • Monostrand tendon – made up of a single steel strand
  • Multistrand tendon – made up of a series of steel strands

Sheathing – also referred to as a duct, this is what holds the series of steel strands or bars together and is found on the ends, next to the coating.

Hydraulic Jack – this material is used to apply tension to the steel itself.


Through the years, the application of prestressed steel strands have proven its worth. Many engineers, architects and designers believe in the great benefits post tensioning can provide any structure.

Here are some of the most common benefits this system has for both buildings and even homeowners.

1. It provides proactive support.

Considering steel bars are incorporated just before concrete is introduced, there is proactive support involved. This means that any other extra load that’s going to be given on the structure could be handled well.

2. It prevents jarring and cracking.

It could be such a horrible experience for homeowners or workers in a building to feel the structure shake and move from time to time. Thanks to post tensioning, you can trust that the structure’s foundation would remain strong and prevent as much cracking and jarring as it could withstand.

3. It adds value to your home.

If you live in a home that’s build through the post tensioning method, then you’re in luck. It guarantees a bigger payout in the end as this process adds a lot to the value of your home.

Post tensioning system has indeed innovated the construction world, as we know it. Considering it’s proven itself to be very effective, we’ll be seeing much more astounding structures in the near future built using it.

Thrifty Tips to Maximize Your Apartment Space

Living RoomLiving in a small apartment can be quite a pain, considering the limited space. This, of course is the mindset of someone who doesn’t have enough imagination— or money.

When you think about it, you can turn your small space into a cozy haven. All you need are these tips and tricks that work and are easy in the pocket.

1. Donate unused items to charity.
If you’ve had that pair of pants for 10 years and it no longer fits you, let someone else wear it. If you’ve got old books you no longer have any purpose for, donate them as well. The key here is to free up some space before moving anything around. So by all means, let go of those things you don’t need or want.

2. Invest on multifunctional furniture.
Instead of getting extra chairs to accommodate more people, buy a bench that has storage space in it. There are even tables with tops you can flip to store more items inside. Another trick is for you to have a bed with space underneath it. That will also count as storage and space saver.

Remember, you want to maximize the minimal space you have so let your furniture help you out.

3. Utilize vertical space.
Go to your kitchen. Are your pans and pots just resting on the counter? If so, buy a pegboard with hooks in it. Place them on the wall and hang the rest of your kitchen items. You’d be surprised just how much space these things can provide if vertical space is used.

The same goes for your bathroom. Place vertical shelves that can accommodate your towels and toiletries. Try not to invest on bulky shelves. The main purpose is to save space, not clog and stifle your bathroom.

I can’t stress vertical space enough. So ensure you make rounds in your apartment to see where it’s best to put narrow shelves on the walls.

4. Neutralize and brighten up the place!
If your apartment is small, then don’t go for dark colors. It’s just going to make the entire space more cramped than it already is.

Go for brighter or neutral colors. It gives the illusion of a more spacious apartment as well as gives you a better feeling. This counts a lot, since we all want to live somewhere we actually love coming home to. So paint your walls bright, trade in your dark-hued furniture for brighter ones and get started.

Oh you know what’s a good trick here too? Let some natural light in during the day. It enlarges the place a tad bit more.

5. Splash an accented furnishing somewhere.
I’ve highlighted just how important it is to live with bright colors. It doesn’t entirely mean you can splash a bit of colorful character in it.

Whether it’s a set of red chairs on white walls and table, an artwork or a decal, this added feature gives your apartment that dash of beauty it direly needs.

So if you want to be in an apartment that’s worth living in, consider these thrifty tips. You’d be surprised how better and lighter you’ll feel afterwards.
