For the builder, becoming an expert in building with cinder blocks ensures numerous projects will beckon his door. This resource gives readers an understanding of how to create beautiful, long-lasting cinder block walls for homeowners.
Know Your Cinder Blocks Better
It is made from cement, water, and aggregates, Cinder block, commonly referred to as a concrete masonry unit, or CMU is available in different sizes, including the standard block measuring 8x8x16 inches. The blocks are hollow, hence less heavy, and easier to maneuver, while still allowing enough space for reinforcement and insulation.
They are unbelievably durable building materials and made of cement, sand, and water; as we discussed above. They are available in a wide variety of sizes and shapes, cinder blocks provide contractors much-needed leeway in design and construction.
Hollow walls are even more versatile. Hollow walls are excellent for reinforcement and insulation, so they can be applied to both structural and nonstructural walls.
This ultimate guide will provide you with the steps on how to build a cinder block wall, the tools needed, and building techniques to create a strong wall on an individual basis.

For example, if the wall size is 30′ wide and 20′ in height, then the area will be 600 sq. ft. (30 * 20 = 600).
Determine the Area of a Concrete Block
Block length x height of block = area of block
A standard 16″ x 8″ block is 128 sq. inches (16 * 8 = 128)
Convert to square feet
128 sq. inches / 144 = 0.889 sq. ft. Calculate the Number of Blocks Needed Formula: Area of wall/area of block = number of blocks
600 sq. ft. / 0.889 sq. ft. = 675 blocks
Step
Formula
Example Calculation
Area of Wall
Length of wall * height of wall
30′ * 20′ = 600 sq. ft.
Area of Concrete Block
Length of block * height of block
16″ * 8″ = 128 sq. inches
Convert to sq. ft. (128 / 144)
128 / 144 = 0.889 sq. ft.
Number of Blocks Needed
Area of wall/area of block
600 sq. ft. / 0.889 sq. ft. = 675 blocks
Total Cost
Number of blocks * cost per block
675 * $5.45 = $3,678.75
Advantages of Cinder Block Construction
Cinder blocks survived through the years proven by advantages like:
Durable
Economic / Affordable
Insulator
Fire Resistance
Versatile
Sound Insulation
Durable
No other material can outperform the strength and durability of cinder blocks. They function much longer than wood and lightweight materials against weathering, impact, and natural disasters. Well-constructed cinder block walls can last 50+ years with negligible maintenance.
Economic / Affordable
Compared to concrete blocks, brick, or stone, cinder blocks are more affordable per square foot. Their material and installation costs are also within reasonable limits, which offers high value in competition prices without compromising quality. They are more affordable compared to other building materials such as brick or stone. This makes them highly suitable for large construction projects
Insulator
Cinder block is a superb insulator. Unfinished cinder block walls regulate interior temperature throughout the year, which helps its users save much on energy bills.
Versatility
Cinder blocks come in different sizes, textures, and colors. Contractors can apply exterior and interior finishes to the blocks to combine practicality with customized looks.
They come in uniform size and shape. These aspects make them very easy to install and even finish up projects fast.
Fire Resistance
Cinder blocks are incombustible, thus putting another safeguard on your construction project.
Sound Insulation
Due to their dense nature, they reduce noise inside the building, giving it a quieter atmosphere.
Therefore, based on these well-supported benefits, contractors realize a tough, yet cost-effective material that caters to various projects, both now and even for years ahead.
Types of Cinder Block
Different types of cinder block securing enable a contractor to make the right selection. Choosing the proper cinder block will depend on any specific requirements of a project, regional climate and budget, and aesthetic needs of the client. Here are the major ones.
Standard Core-Fill Blocks
Solid Cinder Blocks
Lightweight Cinder Blocks
Architectural Cinder Blocks
Standard Core-Fill Blocks
General-purpose cinder blocks for load-bearing walls, partitions, and more
Solid Cinder Blocks
Fully solid structures with maximum weight-bearing capacity are ideal for foundations.
Lightweight Cinder Blocks
Lighter-weight units are better suited for non-load-bearing applications such as fencing but are not as strong as standard blocks.
Architectural Cinder Blocks
The distinctive shapes, textures, and colors can provide another path in imagination besides serving function.
Knowing each type of application and property gives the contractor the ability to select just the right material suited to design criteria and budget.
Guidelines on How to Construct a Cinder Block Wall
Recognizing that proper cinder block installation requires careful procedures. Here are the typical processes contractors follow:
Site Preparation
Dig clear, level, and excavate footings. Lay reinforcement rebar and pour concrete footings
Laying the First Course
Begin with the corners, placing sufficient mortar on the footings and block ends. The blocks should be placed plumb and level
Subsequent Courses
Continue laying courses of blocks ensuring vertical joints are straight. It should be checked plumb and level several times, reinforced when necessary In load-bearing walls, reinforcing rebar is placed in hollow blocks, then filled with grout.
Finish the Wall
Seal any openings and apply your desired exterior finishes such as stucco or siding once the concrete is set.
When these steps are correctly followed, you end up with strong and beautiful structures from cinder blocks that meet building requirements and client expectations.
Tools and Materials that Contractors Will Require
Before you start construction, gather the following tools and materials:
Cinder blocks
Mortar mix
Trowel
Level
Measuring tape
Masonry saw or hammer and chisel
Rebar for reinforcement
Concrete mix for footing
Wheelbarrow and hoe for mixing mortar
Personal protective equipment gloves, goggles, dust mask

Cost of Cinder Block Wall per Square Foot
A cinder block wall will generally range between $5 to $13 per square foot in material cost, with the blocks, mortar, and structural reinforcement included. The type and quality of the cinder block determine the cost of the material.
Labor
A good block wall builder would typically charge between $10 to $17 per square foot for labor. Thus, the average cost for the installation of cinder block walls is about $15 to $30 per square foot.
Per Lineal Foot
It is helpful to know that fences and other elongated, narrow cinder block walls may be quoted by the lineal foot instead of square foot. Based on wall height, cinder block walls may fall in a pretty big range of $60 to $240 per linear foot.
There are more expensive materials and less expensive materials. The least expensive is the cinder block. The cost for installation runs from $5 to $13 per square foot. And this is both the block and the mortar as well.
Installation of a cinder block wall will cost five to thirteen dollars per square foot. This includes the price of the block as well as the mortar, and any structural reinforcing of the block. Of course, this can vary depending on the type and grade of the cinder blocks used.
Labor Costs
The labor cost for hiring an experienced block wall contractor starts at about $10 and goes as high as $17 per square foot. That being the case, the total cost incurred for setting up a cinder block wall installation usually falls under the

DIY Blockwork vs. Hiring a Pro
Blockwork in cinder blocks needs quite a lot of planning and technique in masonry. Depending on what you want the wall to be used for, you will need varied professionals.
Load-bearing walls and structures that demand high technical competency.
Suitable for decorative walls like garden walls or low fences.
Walls needed to have reinforcement with drainage or backfilling
Walls that are on slopes or unusually tall structures.
Any wall that would require a building permit.
Remember that any wall designed purely for ornamentation separates a space visually but is incapable of carrying structural loads. However, any wall that forms part of a building needs to carry loads and so can only be constructed by a person having proper skills.
Final Thoughts
As the following comprehensive reference guide illustrates, cinder block walls are an excellent construction solution used by professional contractors dedicated to protecting customers, property, and reputations. Provided the materials, techniques, pricing, and practical difficulties are explained, there is every likelihood that the various cinder block works will be managed successfully for a long time.
