Concrete floors have become very popular offering many advantages such as durability, versatility and easy maintenance.  They are long lasting and can survive under high traffic conditions.  Concrete slabs also make a good sub-floor for laminate floors, tile, linoleum, carpet and other applications.  Essential for a new slab or the repair and/or reconditioning of an existing floor is surface preparation.

Surface preparation equipment is used to polish or grind concrete surfaces or to remove previous treatments.  If your job requires leveling uneven joints or surfaces, eliminating trip hazards, or the removal of coatings, adhesives or mastics – then a concrete grinder is the tool you need.

When choosing a concrete grinder, the first thing to consider is what you are planning to use it for and the size of the job you will be doing.  Let’s take a moment and look at the different equipment rental options for preparing or grinding a concrete surface.

Surface Grinder

Surface Grinders:  Concrete floor (surface) grinders are used for applications such as grinding or cleaning concrete surfaces, leveling uneven joints & removing epoxies, high spots, mastics, thin-set & urethanes.  We offer a full line of grinding tools & conventional attachments including Grinding-Stones, Dyma-Serts and Strip-Serts to meet your surface preparation needs.  Surface grinders work well for light grinding or cleaning of concrete surfaces.  If you have a significant amount of concrete to grind (say more than ¼”) you’ll have to make several passes with the machine.  If the dual-headed concrete grinder is too big, consider renting a 16” heavy-duty floor machine with the grinding attachment that uses the same attachments as the dual-headed floor grinder.  The 16” floor machine also has a sanding attachment as well as a scrubbing brush attachment for cleaning a floor.



 Scarifier:  A scarifier is a surface preparation machine that will clean, texture, level, groove, and remove material from concrete flooring.  Scarifiers remove concrete faster and more aggressively than surface grinders as they use the pummeling action of multi-tipped cutting wheels, or flails, that rotate at high speeds to chip away at the concrete surface.  Keep in mind that scarifiers leave a rougher finish.  If you need a smooth finish you will need to use a concrete floor grinder to achieve it.

Teq-Edge Floor Grinder

 Teq-Edge Floor Grinder:  The Teq-Edge floor grinder is a very versatile surface grinder that uses an 8” diamond disc to grind the concrete.  The Teq-Edge is designed to get into tight or hard to reach spots, including being able to grind up to the edge of a wall.  The diamond disc allows for fast grinding of uneven slab surfaces, removing excess surface material, leveling patches of plastic overlays or grout and feather-edging sidewalks, gutters and similar surfaces.

Hand Grinder

 Hand Held Grinders:  These are ideal for small jobs like areas close to walls and other hard to get places.  They are also ideal for removing blemishes to concrete work.  They are very light and easy to use.  Our hand held grinders can be outfitted with either 4” or 7” abrasive grinding wheels or with a 5” silicone carbide grinding cup stone.

 Safety First:  Please remember that all cement products contain sand.  When that substance is released in the air, as will happen when using a power tool on concrete, the operator of the machine will breathe it in if a dust mask or respirator is not worn.  Concrete dust can cause long-term health problems for the operator or anyone else who breathes it.  Always wear a dust mask or respirator and safety goggles to protect your eyes and lungs from the dust that will be released by the removal process.


Does your concrete project require more finesse than simply breaking up the concrete with a jackhammer?  A cut-off saw, floor saw or concrete chainsaw may be the answer.  All three items provide the capability of cutting concrete and in some instances asphalt with control and precision.  Let’s take a look the capabilities of the different concrete saws available for rent.

 Cut-Off Saws


For most concrete cutting jobs, the cut-off saw is a popular choice.  These hand-held saws can be used to cut concrete, asphalt and metal.  Cut-off machines resemble a chainsaw, however they have a circular blade instead of a chain and bar.  Typically available in 12-inch or 14-inch blade sizes, cut-off saws can be powered by a two-stroke gasoline engine or an electric motor.  Abrasive (silicon carbide material) or diamond- rimmed blades are the most common saw blades for cutting concrete.  Both blades are used to cut or score concrete, with our 14-inch (blade diameter) cut-off saws able to cut up to four inches deep.  When used to “score” concrete, the “score line” allows for a nice cut-line when breaking out a concrete section.

 Concrete Chain Saws

concrete chainsawIf you need to cut an opening deeper than 5-inches, you might want to consider a concrete chainsaw for your job.  Our concrete chainsaws have a 12-inch bar and work great for cutting out openings in concrete for plumbing, electrical components, windows and more.  This saw is also designed like a chainsaw using a power head, guide bar and diamond chain.  A two-stroke gasoline engine powers our concrete chainsaws and the saws use a chain that incorporates diamond segments that are laser welded to the chain in place of the cutting teeth typically found on a wood chainsaw.  The diamond segments create a grinding action that wears away the concrete.  This grinding action creates a very safe cutting operation with no kickback and each chain will cut from 30-feet to 60-feet of concrete.

While similar to a concrete cut-off saw, a concrete chainsaw is designed to plunge nose first into the concrete and has the ability to cut more than twice as deep as a 14-inch cut-off saw.  Concrete chainsaws provide a deeper cut with no over-cut, allowing you to make square corners, which is not possible with a cut-off saw.  They can be used to make openings as small as 4-inches by 4-inches and to cut odd shapes and sizes.

 Concrete Floor Saws

8hpconcretesawWalk-behind concrete saws or “floor saws” are used to cut sections of flooring or similar flat sections.  Our 14-inch saws will cut up to a depth of 4-inches.  This type of saw can be used for scoring concrete for slab removal with a jackhammer, making expansion cuts to new concrete slabs, and cutting asphalt.  These saws are gasoline powered and similar to the cut-off machines use either a silicon carbide abrasive blade or a diamond-rimmed blade.

 Diamond Blades vs. Abrasive Blades

As mentioned above, you have the option of using either an abrasive blade or a diamond blade when using a hand held cut-off saw or a walk-behind concrete saw.  The abrasive blades work well for small cutting jobs in concrete, asphalt, or even metal.  The downside to abrasive blades is that they wear as you use them (similar to a grinding wheel) so the blade life is much less than the life of a diamond blade.  Diamond blades allow for a faster cut and offer a constant cutting depth.  They are available for purchase or rent and are a much better value if your job requires a significant amount of cutting.  While we have dry-cut blades available, most of our diamond blades are “wet-cut” requiring water to keep the blade cool (which extends blade life) and the dust down.

 Safety First

With any project safety comes first.  The cutting of any material using power tools creates dust and flying chips.  We recommend the use of safety glasses with side shields or safety goggles, work gloves, a work apron or close fitting clothing, hearing protection, and an approved dust/mist respirator.

Spring Seminars 2014: Sanding Hardwood Floors

Posted: February 6, 2014 by Bunce Rental in Uncategorized

Stop by our downtown Puyallup store on Saturday, March 22 to learn tips and tricks for sanding your hardwood floors. Jim Wolfe, from Essex Silverline Corporation, will join us again for our third annual hardwood floor sanding seminar.  Aside from helping you understand your options and the process for sanding your hardwood floor, you’ll have the opportunity to try out the floor sanders on a hardwood floor. So mark your calendars for Saturday, March 22 and join us at 1812 East Main St in Puyallup to attend this free seminar. Free doughnuts, popcorn, and coffee will be provided.

Hardwood Floor Sanding Seminar

Recently, we discussed the different types of jackhammers and pavement breakers available for rent in “Bust A Move With A Jack Hammer”.  As mentioned, the type of material and application you are working with will determine the type of hammer and tool bits (point, chisel, spade, etc.) you will need to efficiently complete your job.

The different tool bits let you break, cut, dig, or tamp using the same electric or pneumatic hammer and by choosing the right jackhammer tool for your job, you will be able to complete your work easier, faster and safer.  The material you are working with usually tells you which tool you will need to use.  For example, if you use the wrong jackhammer tool the concrete may not give it back or you’ll spend time punching holes in the concrete without doing much breaking.  That is why it is important to learn which tools are made for each type of job.

Concrete Points and Chisels

The standard moil point and the narrow chisel are the most widely used all-purpose tools for concrete breaking.  When using either of these tools it is important not to pry too much with the hammer as the tool shank could break prematurely.  Larger chisel bits are popular for scoring normal-strength concrete or breaking up weak concrete or other materials that are too soft for efficient moil point or narrow chisel work.  With soft materials, a moil point simply punches a hole, while a chisel bit does more breaking or chipping.

Asphalt Spades and Clay Spades

For materials such as asphalt use an “asphalt spade” with a 5-inch wide blade.  It cuts through thick asphalt pavement and removes deteriorated asphalt quickly.  But don’t use this tool to break or cut concrete – the thin blade and softer steel is too easily damaged.  Spades for clay or hardpan cutting and removal come in blade widths of 4-1/2 inches and 5-1/2 inches.  The blade section is thin and curved for faster cutting and easier earth removal.

Bushing Tools

Bushing tools are used to remove high spots in a floor or to roughen a surface for better adhesion of overlayments and top coatings.  Engineers sometimes specify a bushing tool for roughening concrete surfaces at construction joints.  The tool also is used for texturing architectural concrete surfaces.  Bushing tools have a serrated face with rows of pyramidal points made of hardened steel.  Typically there are 9 or 16 points.  The paving breaker tool has a 2” square face and the smaller chipping hammer and electric hammer tools have 1-3/4” square faces.

Rod, Stake and Pipe Drivers

You can also save time and effort by using tools that drive rods, stakes and pipes into the ground.  Ground rod drivers, furnished in diameters ranging from 5/8” through 2-1/2”, are used to drive form pins, curbing pins, and different sized steel and stakes.  A pipe driver, designed to accommodate more than one size pipe, uses a center stem to guide the pipe and the cup does the driving.


To use a jackhammer or pavement breaker as a tamper, a shank with a square or round tamper pad can tamp backfill or repack loose materials in tight corners or narrow trenches.

Sharpening:  All of our points, chisels, spades, and bushing tools are professionally sharpened after each rental.  This ensures that each tool has the right cutting angles and is properly heat-treated to restore the integrity of the steel before use.

Remember, the right “tips and bits” make a jackhammer, chipping hammer or pavement breaker one of the most versatile and productive tools you can rent!

Three Cubic Foot Concrete Mixer Electric

Three Cubic Foot Concrete Mixer Electric

You’re ready to pour that concrete slab for your new patio, hot tub, or storage shed.  Depending on the size of your slab, ordering a concrete truck may be overkill or a portable concrete mixer may not be enough to handle the job.  Today’s blog will cover the different concrete mixer and mixing options available from Bunce Rental.

Concrete Mixers

A concrete mixer combines cement, sand or gravel and water to make concrete.  Mixing concrete by hand, without using a concrete mixer can be pretty grueling and challenging work.  Portable concrete mixers are perfect for any small or medium sized job.  They are easily operated by one person and can easily be moved from one place to another.  We rent different types of portable concrete mixers: electric 3 cubic-foot mixers, which are stand mounted or towable, gasoline powered 9 cubic-foot mixers.

The principle behind both the portable concrete mixer and a concrete truck is the same.  The revolving of the drum mixes the ingredients together and then keeps the concrete from drying and hardening.  Port able concrete mixers are described in terms of drum capacity.  So a 3 cubic-foot mixer has a drum capacity of 3 cubic-feet. Batch output capacity is a different measurement.  While a concrete mixer might have a 3 cubic-foot drum, its actual batch capacity will only be around 1-1/2 cubic-feet.  So, don’t go only by the size of the drum, as when mixing concrete the drum will be at an angle and will only be 2/3 full.  The electric mixers come with a stand, which enables the mixer to be upright, allowing you to mix a pretty full drum load.

Nine Cubic Foot Concrete Mixer Gas Powered

The 9 cubic-foot towable mixer is a heavier duty machine.  As the name implies, they can be towed behind a vehicle and used for different jobs and in different locations.  A gasoline motor powers them and the drum has an attached lever that allows the drum to tip down and the concrete to pour into a wheelbarrow.

U- Cart Concrete

For projects that require larger loads, but not enough to justify having a truck deliver the concrete, check out our U-Cart Concrete.  Our professional concrete blending system is capable of producing up to 15 yards of ready mixed concrete per hour.  Using your ¾-ton truck or larger tow vehicle, take one of our tandem-axle mixing trailers with up to 1-yard of concrete to your jobsite; back up to your form and using the built-in hydraulic jack, place the concrete right where you need it.  While 1-yard of concrete may not sound like a lot – most people don’t realize that mixing just one yard of concrete would require over 40 bags of sack concrete.  What a great way to save time and money!

IMG_8897U-Cart Concrete is available for purchase at our Tacoma, South Hill Puyallup and Parkland / Spanaway locations.  Our concrete is made with premium-quality Portland type II cement and a premixed sand and 5/8″ pea gravel aggregate.  Since a trailer with a full load of concrete weights over two tons, we recommend at least a ¾-ton pickup for towing and a receiver hitch rated for 6000 pounds with a 2″ ball.  Remember, the maximum towing speed is 35 mph due to the weight involved.  You should have all site preparation done before coming to get concrete, and it is best to dump the concrete immediately on arrival at the jobsite, especially in hot weather.  If you are unsure of how much concrete you need, our online concrete calculator can do the math for you.  To use our online calculator or learn more about our U-Cart Concrete systems, go to our website at

Bust A Move With A Jack Hammer

Posted: January 7, 2014 by Bunce Rental in Uncategorized

We have all heard or used the term “Jackhammer”, which in general refers to a heavy tool used to break hard substances such as concrete, asphalt, or pavement into pieces by a repeated pounding action.  It is a tool that sounds like a simple solution to bust up concrete or other hard surfaces – just rent one and bust away!  But not so fast…

The type of material and application you are working with will determine the type of hammer and tool bits (point, chisel, spade, etc.) you will need to efficiently complete your job.  For example, if you are breaking concrete the thickness of the concrete will determine the type of hammer and tool bit required.

Jackhammers or breakers are available in several sizes (many classified by weight) and can be electric, gasoline, pneumatic or hydraulic powered.  They also have many uses including: breaking concrete, cutting asphalt, digging, driving fence posts, driving rods and spikes and tamping or compacting soil.  In our next blog we will describe the assortment of bits available for the hammers that provide options to tackle the toughest demolitions jobs.

Electric Chipping Hammers and Breakers

45# electric hammerElectric hammers and breakers are great for smaller jobs.  They are extremely portable and easy to use.  The 30 lb. Electric Hammer or “chipping hammer” is a drill-like tool, such as a Bosch, which can be used for chipping away thin concrete, mortar, bricks, or any tile (ceramic, porcelain, etc).  These tools excel at removing tile from floors and walls, and also at removing patchwork from concrete surfaces.  The 45 lb. Electric Hammer is easier to use on walls and from scaffold than the bigger 60lb hammer.  It is ideal for tearing down old fireplaces or breaking down block/brick walls.  The 60 lb. Electric Hammer is the industry standard for breaking up concrete indoors or out (up to 4” thick).

Gasoline Powered Hammers

With no compressors, hoses or cords to set up, a 65 lb. gas-powered hammer is ideal for many jobs.  They are indispensable for tasks that involve moving along a line, from position to position or for working in remote, inaccessible locations.  They work best for concrete jobs up to 4” thick.

Pneumatic Hammers

60# air hammerPneumatic or “air hammers” use compressed air as the power source.  The air supply comes from a large (usually towable) air compressor.  We typically match up our hammers with our 185 CFM Air Compressor, making the hammers good for larger jobs, particularly if the concrete is more than 4” deep.  The compressed air provides the extra power to chip away at and bust up the concrete.  Pneumatic hammers will typically do the job faster than electric hammers too, especially if there is more concrete to break up.  We carry pneumatic chipping hammers; rivet busters and 60lb or 90lb jackhammers.


Hydraulic Jack Hammer

Hydraulic BreakerThe skid steer (Bobcat) hydraulic jackhammer attachment (Breaker Hammer) is the tool of choice when you have a large concrete removal project on your to-do list.  It works best for larger demolition jobs, such as tearing down block walls, poured concrete, concrete slabs, floors and footings.

Remember to take property safety precautions when using any jackhammer or breaker and always wear protective clothing, gloves, eye and hearing protection.
