Whether you are working on a foundation, driveway, basement, or hardscaping a backyard, concrete is everywhere in a house renovation project. In this buying guide we will focus on what makes up the best concrete mixers for house renovation and hardscaping jobs.
A concrete mixer is a motorized machine that mixes your cement, aggregate, and water into a consistent solution. Concrete mixers use a revolving drum and blades to mix the elements thoroughly.
For larger jobs, concrete trucks are the go-to option. But for the average sidewalk, patio, or retaining wall job a mobile concrete mixer is a necessity.
Concrete Mixer Designs
Concrete mixers in two different designs: forced mixing or gravity mixing.
In forced mixers, the drum stays fixed and the blades spin separately like a blender.
In gravity mixers, the drum rotates and blades either stay stationary, or move with the drum if attached to the drum walls.
Both designs have their pros and cons, but the most common are gravity mixers because they tend to be simpler, more reliable and less costly.
The Four Components of a Concrete Mixer
A concrete mixer used for house renovation and landscaping projects is made up of four main components:
1. Drum – Drum size determines the capacity of the mixer. The drum material determines the durability and ease of cleaning.
2. Motor – The motor drives the mixer’s rotation speed and velocity. It can be electric or gas-powered.
3. Frame and Wheels – A sturdy frame is needed to house the drum and motor, preferably with large durable wheels for easy movement on rough surfaces and highway travel (if you’re pulling it behind a truck).
4. Crank Wheel – Controls the angle of the drum (up for mixing, down for pouring). Crank wheels are found on larger mixers that can’t be manually tipped up or down.
Mixer Drum Capacity
The capacity of the concrete mixer’s drum dictates how much concrete you can mix at a time. Capacity is calculated in cubic feet.
When you are mixing multiple batches, the more concrete your mixer can churn out, the less you have to wait for the next batch, and the more consistent your pours will be. This becomes important for large area pours like patios and driveways, particularly in warm weather.
Keep in mind that not all of a mixer’s capacity can be used. If you have a drum of 5 cubic feet, you will only be able to use roughly 4 cubic feet of it (normally 80% of the total drum capacity).
Some people measure a mixer’s drum capacity by the number of cement bags it can process. Let’s say you have a 94 lbs bag of Portland cement; this translates to a volume of 1 cubic foot. If you are combining a usual mix of 1 part cement, 2 parts sand, and 3 parts gravel or stone, per Sakrete’s Portland Cement specs (opens PDF in new tab) this will convert to around 4.5 cubic feet of concrete.
Mixing Motor Power
The power of a concrete mixer’s motor is crucial because it determines how many times the solution is mixed in a minute. Most concrete mixers for home renovation and hardscaping projects have motors ranging from 1 to 5 horsepower.
A strong and reliable motor is essential because bigger jobs often require a concrete mixer to work for hours and hours. If the motor heats up and slows down when run at full capacity, it can affect your entire job.
It’s important not to confuse revolutions per minute (RPM) with power. A smaller, less powerful motor can be “geared up” to spin the drum at higher RPMs, but this puts much more stress on the motor. The motor can also be run at higher RPMs to turn the drum faster. In either case, you’ll end up with shorter motor life. What you’re looking for is the right level of power for the typical size and frequency of jobs you’ll be doing.
The two most common materials used for concrete mixer drums are steel and plastic (commonly called poly drums).
Poly drums reduce the overall weight of the mixer; they are easier to clean because the concrete doesn’t stick to the poly material they way it does to steel. But these drums are susceptible to faster wear due to abrasion from the aggregate.
Steel drums usually have much longer life. They are more resistant to abrasion. But they are heavier, harder to clean and require a more powerful motor. On the bright side, with a steel drum you don’t have to worry if you need to hammer out hardened concrete that’s lodged in the drum.
Frame, Crank and Wheels
The frame of the best concrete mixers are sturdy enough to support the weight of the mixer at full capacity on uneven ground. The frame must be durable enough to last many years riding in or being towed behind a truck. If the frame is flimsy, it can shake and vibrate once you fill the drum with concrete. Vibration will eventually crack the frame and make the components wear out faster.
The crank wheel is part of larger mixers. It is used to pivot the drum separately from the frame to pour concrete into a wheelbarrow, ditch or wood form. The crank wheel should be solid enough to handle the weight of a full drum for many years. It should not have sharp edges. A diamond texture on the wheel increases grip when it’s wet.
A good concrete mixer should have sturdy wheels with a strong axle and bearings. These should be large pneumatic or solid rubber tires. If the mixer will be pulled behind a truck the wheels and tires must be highway rated.
Gas vs. Electric Concrete Mixers
Concrete mixers for house renovation and hardscaping projects can have either a gas or electric motor.
For small scale renovation jobs, electric mixers are typically enough. They are simple to handle, don’t require any additional maintenance, and are easy to put together. However, they do require close proximity to a reliable electricity source or large generator. Electric concrete mixers are ideal for urban environments because they tend to be quieter.
Gas-powered mixers are ideal for jobs where there is no electricity. They allow far more portability and can be used far away from buildings. But they are usually heavier and bulkier. Gas-powered motors require more maintenance and a ready supply of fuel. They are also louder and more harmful to the environment (if you’re a green builder).
Mixing Different Types of Concrete
Mixing concrete correctly for the job at hand is critical. The correct ratio of cement, aggregate, and water need to be mixed consistently.
You want the best concrete mixer to cover all your bases:
- High aggregate content concrete for driveways and foundations
- Smooth mortar for brick walls
- Quick drying concrete for cold weather pours and post holes
- Crack-resistent cement for patios and walkways
- Mixing in dyes, plasticizers and chemicals for specialty design work
The ability to mix concrete quickly and consistently with minimal manual labor the best reason to invest in a good mixer.
Five of the Best Concrete Mixers
Here are our picks for the five best concrete mixers for house renovation and hardscaping projects. We hope these reviews will help you choose the best mixer for your needs.
1. Multiquip MC64SE Electric Concrete Mixer
Starting off our list of the best concrete mixers is a large capacity electric mixer by Multiquip. This fireman-red mixer has a drum size of 6.0 cubic feet. Using the 80% rule, the Multiquip will easily mix up to 4.8 cubic feet of concrete in a single batch.
The Multiquip MC64SE mixer’s drum is 29 inches deep, and the mouth is 19 inches wide. The drum is made of sturdy powder-coated steel.
The overall height of the Multiquip mixer is 59 inches. The discharge height (the height the drum pours concrete from) is 23 inches — perfect for pouring into a wheelbarrow or chute.
The mixer is driven by a single-phase electric 115/230 volt 1.5 hp Baldor motor. This motor is known for its excellent quality and long life. It uses a V-drive configuration which isolates the motor from the drum and reduces vibration and noise.
The frame is powder-coated tubular steel, sturdy enough to handle the operating weight of 685 lbs. It uses a single piece cast iron ring gear, which gives it a much longer life than a welded ring.
The mixer rides on heavy-duty 13-inch wheels for maneuverability. These will last you many miles of towing.
You can find the Multiquip MC64SE’s spec sheet here.
PROS of the Multiquip MC64SE
1. Large capacity means shorter wait times between consecutive mixes.
2. A multi-position dump latch gives you more control over your pouring options. You can pour into a wheelbarrow standing right by the mixer, or angle the pour to target frame on the ground.
3. Well-built, made to last for a long time in harsh environments.
4. Built-in towing tongue makes transportation easy. The tongue is retractable onsite so it won’t get in the way of mixing and pouring.
CONS of the Multiquip MC64SE
1. Very expensive. You should invest in the Multiquip only if you plan to pour lots of concrete for years. This is a contractor-level mixer.
2. Large and heavy, making it harder to maneuver compared to a smaller mixer. You will need a truck to pull it and a decent size spot to park it.
3. Bulky due to the V-drive motor layout. The motor sits away from the drum in its own enclosure. This makes it hard to maneuver into tight spaces and you’ll need to pour concrete into a wheelbarrow first on many projects.
2. Imer Wheelman II Gas Concrete Mixer
The next contender for best concrete mixer is the Imer Wheelman II. This is smaller mixer designed for lighter jobs, with a 5.0 cubic foot drum allowing you about 4.0 cubic feet of mixing capacity. This small mixer can handle about 275 lbs of concrete.

Final Tips on Using a Concrete Mixer
No matter which concrete mixer you choose for your home renovation or hardscaping projects, there are a few tips you should follow.
1. If you are not using a premade concrete mix, make sure you know the ratio in which you are mixing aggregate and cement. Different concrete ratios are best for different jobs.
2. Clean the mixer as soon as you can before the concretes dries. Chiseling hard concrete off a mixer is tedious and increases wear and tear.
3. Keep the concrete load a bit under the maximum allowed weight and volume. This will increase the life of your motor.
4. Always start the mixer before loading the drum. Higher starting loads put a lot of stress on the motor.
5. Unless required otherwise, try pouring in this sequence: Gravel, cement, sand, and water.
There are just a few good practices that will help extend the life of your concrete mixer and keep it working hard, instead of giving out in the middle of a job.
