Cinder Blocks Explained

Cinder Blocks Explained

Cinder block sizes vary and many different shapes are available for your outdoor projects.  There are short ones, tall ones, solid ones and some are made with holes/voids.  Not only are they different sizes, but some that are classified with the same dimensions can be slightly different allowing them to be used in a different manner.

You can build outdoor structures such as fireplaces, kitchen, and pizza ovens using primarily the blocks that are described in this article.  Just for a bit of clarification, most people will call them cinder blocks but there is a slightly more technical term for them.  They are sometimes referred to as concrete masonry units (CMU) by the folks that make them and sell them.  When shopping for these blocks, you only need to call them cinder blocks though and know a little about how they are sized.  The cinder blocks sold in the United States are sized in inches.

Cinder Blocks and Sizes Explained

8x8x16 Block

8x8x16 block

The most common cinder block is an 8x8x16 as seen in the adjacent picture.  These measurements are the depth, height, and width respectively.  Most construction projects, needing any structural integrity, will be built using this size block. These blocks have voids, designed to be filled with concrete, which provides great strength.

These 8x8x8 cinder blocks are perfect cubes that are widely used in conjunction with the 8x8x16 cinder blocks.  These blocks also have voids which allow them to be filled with concrete.

Some have notches manufactured into them for rebar, but the notch will not be used most of the time.  When you are building using a running bond/staggered pattern, these will certainly be useful.

 

8x4x16 block

An 8x4x16 cinder block is half as tall as standard 8x8x16 cinder blocks, so they are very good to incorporate into your structure. These cinder blocks are used as a transition block when only a little bit of height is needed as they are only 4” tall.  These blocks also have voids.

 

 

 

4x8x16 block

Occasionally, you will need a cinder block that is only 4” in depth.  These cinder blocks are measured 4x8x16. They have much smaller voids in them which makes them harder to fill with concrete.

A lot of cinder block walls are constructed using these blocks.

 

 

 

8x2x16 cap block

Use these cinder blocks for finish work and solid surfaces.

One of the last widely used cinder blocks is an 8x2x16 cap block.  When you only need to add a couple inches to your structure or to close off a section, you will use these blocks. These cinder blocks are solid and are also used when a flat surface is needed for finish work.

If you are interested in building an outdoor fireplace or kitchen there are great ways of building them.  Cinder blocks are just one way of constructing them, but it’s a fantastic way to build a structure with great integrity and strength.  Visit www.backyardflare.com for great outdoor fireplace designs, ideas, and DIY construction plans.

 

 

Great Ways to Finish Your Outdoor Fireplace

Great Ways to Finish Your Outdoor Fireplace

There are some great ways to finish your outdoor fireplace.  Basically, there are endless of ways to add the finishing touches which will make your outdoor fireplace a one of a kind.  Even if you build the basic rough structure that another person constructed, yours will look different.

If you pay attention to detail, your fireplace and backyard landscape can look like something in a magazine.  We will cover five of the big finishing touches and things you can do to give your fireplace the wow factor.

1. Low voltage lighting

Even when the fireplace is not being used, low voltage lighting is a great way to add a great night time visual aspect to it.  The lighting is powered by a transformer specifically designed for these types of lights.  By connecting the fireplace lights to landscape lighting in your yard, everything will be illuminated at the same time.

Lighting adds a great look to any fireplace
2. Natural stone seating surface

By using a natural stone material for the seating, you will have a very durable, and inexpensive surface.  There are a couple widely used stone options, such as flagstone and bluestone.  Both can be purchased at landscape supply retailers and you will have tons of colors and patterns to choose from.  Cutting the stone is as simple as using a diamond blade for a smooth edge or a chisel and hammer for a rough rustic edge.

Natural stone was used for the seating surface, shelves, and top.
3. Stacked Stone Veneer

Stacked stone is a great way to finished the vertical surfaces of the fireplace, but it can be somewhat expensive as compared to other finish options.  This type of material is purchased in arrangements that will fit together seamlessly.  The stone is real and engineered during the cut process, meaning that it will be very easy to install.  Cutting this stone will take a bit more time and patience as it is sometimes brittle.

Stacked stone added to the fireplace hearth.
4 . Faux Veneer

Faux veneer is a fabulous way to add a cheaper finish to the outside of your fireplace than natural stone.  The great thing about faux veneer is that you can find virtually any texture, color, shape, and size imaginable.  The faux stone is basically a manmade product that is painted and finished to look just like a real material.  The faux stone is very easy to cut but it may take a bit of extra time fitting it together.  There is no “one way” to put it together most of the time, so using your Tetris skills will come in handy.  Faux veneer will usually require corner pieces that will give you a great finished look as the material wraps from one vertical surface to another.

5. Wrought iron accents

Wrought iron accents will add both a décor and some functionality to your fireplace.  First, add an elevated fire grate in your firebox.  This will both give you a great look, but it will aid in keeping your burning wood elevated for proper air flow.  Fireplace tools will give you the capability of working and stoking your fire as you need to.  Many tools sets will come with a holder as well keeping it nice and neat.

Building a Dream Backyard

Building a Dream Backyard

The latest fireplace profile comes to you from South Carolina.  Builder and homeowner Nick had plans of building a dream backyard and he contacted Backyard Flare, LLC for help.  Nick is a DIY enthusiast and he knew he could build his own outdoor fireplace. He chose the Douglas design and got his construction plan from Backyard Flare.

Starting Off With a Blank Slate

Building a Dream Backyard
DIY fireplace built in South Carolina using a Backyard Flare DIY construction plan.

Nick had an existing stamped concrete patio in his backyard with a small flowering garden on one corner.  The patio wasn’t designed or constructed with weight bearing in mind so Nick poured an additional slab for the fireplace.  Nick built a wood frame to see the footprint of the structure as well.

Building a Dream Backyard
Nick had a bunch of bushes to remove.

Drainage was added to the slab so that water would not accumulate.  This is a very smart move when building a non-linear structure.  The drainage was built through the entire slab so any water drained behind the structure.

Nick’s DIY Construction

The cinder block work was started with the wing walls built to the same height as the main seating section.  The normal Douglas design has the side extensions higher than the center seating section so this modification was Nick’s vision.

Ready for Veneer
Nick finished the rough build phase of construction.

The entire structure was built in rough form, then it was time for veneer and finish work.  Nick covered the horizontal surfaces with a neutral flagstone.  The edges were left rough for a great outdoor look.  Nick chose a great looking faux stone with a relatively small pattern.  The pieces were not all the same size so there was a bit of puzzle piecing the veneer together.  This task slows down the construction but it makes for a great looking veneer pattern.

Nick added flagstone for the seating and a great looking veneer to the vertical surfaces.

After the construction was completed, Nick added a couple colored deck chairs and a rustic piece of log for a small “beer holder”.  The chimney was adorned with a great looking wreath and a log holder was added for spare firewood.

Nick used veneer on the backside of the fireplace for complete finished look.
