Dowels are cylindrical rods made from plastic, metal, or different types of wood and can be cut and sanded to any size to suit various end uses. They are commonly cylindrical in shape and usually made from wood. They can be used for crafting, woodworking, or even as a plant stake for young plants.
Darice Dowel Rods, made of poplar, offer the best all-purpose dowel rods in their book. These rods feature a tight grain and look uniform, making them easy to make in the workshop using scraps. However, most dowel rods are made of pine or unknown material that would not do well outside. Outdoor use is suitable for holding lightweight flags or as plant stakes for young plants.
Dowel rods are prepared on a specialist machine and sanded to a fine finish. Lowe’s carries hardwood dowel rods in both round and square shapes in lengths from 12 inches up to 72 inches, as well as in a wide range of diameters, from 3/16 inch to 1/8 inch.
Dowel rods are commonly cylindrical in shape and usually made from wood, making them an ideal alternative to mortise and tenon joinery. Waddell offers a hardwood round dowel, 96 in. x 1.25 in., sanded and ready for finishing, making it a versatile wooden rod for DIY home projects.

What is the rule for dowels?
Dowel size is typically determined by the thickness of the pavement, with a diameter of 1/8 of the pavement thickness. The minimum embedment length on each side of the joint should be 6. 0 inches. Dowels are typically used for load transfer across transverse, sawed, and contraction joints. If the pavement is properly designed and has a thickness of 8 inches or more, dowels should be used at all transverse joints.
If the design is less than 7 inches, dowels may not be needed at transverse contraction joints due to insufficient truck traffic. The use of dowels between 7 and 8 inches depends on factors like traffic patterns and speed.
What is the best wood for outdoor dowels?
Woods react to humidity and temperature changes by expanding or contracting, with poplar being more resistant to these changes. Some woods, like cedar and mahogany, are naturally resistant to decay, pests, or moisture damage, making them suitable for projects exposed to moisture. White oak is ideal for outdoor use. When finishing a project, consider the wood’s finish properties, as some woods, like cherry, may not require staining, while others, like pine, may absorb stains unevenly due to their softness.
Can dowels be used outside?
Outdoor furniture should be made of weatherproof materials like Sipo mahogany, bangkirai, or KNAPP dowels.

What type of wood are dowel rods made of?
Wood dowels are cylindrical rods made from plastic, metal, or wood, available in 3, 4, 5, and 6 feet lengths. They come in various species like poplar, cherry, red oak, and hard maple. The hardness of the wood determines the strength of the dowel rod, but a quality dowel rod easily surpasses the strength of a nail or screw. Baird Brothers manufactures quality wood dowels using a tried and true method.
Dowel rods are useful for various projects, including furniture making, as they impact the quality and strength of butt joints. They can also be used for other purposes beyond expert joinery, such as repairing damaged or damaged wood.
Are dowels always made of wood?
A dowel is a cylindrical shape made of wood, plastic, or metal, often used as structural reinforcement in cabinet making and other applications. In its original form, a dowel rod is long and cut into shorter pins. Dowels are commonly used in furniture shelf supports, moveable game pieces, hangers, wheel axles in toys, detents in gymnastics grips, and supports for tiered wedding cakes. To make a dowel, a piece of wood is split or whittled to a slightly bigger size and driven through the hole in the dowel plate, with the sharp edges of the hole shear off the excess wood.
What grade are dowel bars?
Dowel bars, with diameters ranging from 16 to 50mm, are supplied in strength grades 250, 500, and 650, in accordance with the European standard for reinforcing concrete, BS 6744:2016. The dowel bars are accompanied by rigid PVC caps with a compressible filter for expansion.
Are dowels hardwood or softwood?
Fluted dowels are typically made of hardwood, while plain dowels are made of pine. Hardwood is stronger and easier to work with, while ribbed dowels have a good surface area for glue. All dowels in joinery should be tight fit, and the functional surface area for glue is larger for plain dowels unless using gap-filling adhesive like epoxy or Aerolite. Fluted dowels have grooves that only touch the side of the hole, forming a strong joint. Modern dowels often fail with white or yellow carpenter’s glue.
What wood will last longest outdoors?
Wooden outdoor furniture is generally considered the most durable and rot-resistant type, with hardwoods like ipe and teak being the most durable. These woods can last decades with minimal maintenance, making them ideal for outdoor use. However, it is important to note that any wood outdoors will eventually degrade over time, so it is recommended to use natural oil finishes that can be replenished. Plastic clear coats can eventually yellow and start peeling off, making them unrepairable.
To maintain wooden outdoor furniture, it is essential to clean it with soapy water at the start of spring and apply a couple of coats of your chosen wood stain or paint. Some people let their furniture age naturally, giving it a rich golden brown color, but personally, I prefer a rich golden brown color. Applying an all-weather varnish, such as BEHR Premium Transparent Weatherproofing All-In-One Wood Finish, with a repeat application in Spring every 2-3 years, can help seal up the wood from outdoor elements like UV light, rain, snow, wind, and hail.
Choosing the right wood species reduces the need for regular care, but it does not mean regular care won’t extend the life of furnishings or improve their appearance. All furnishings should be given an occasional cleaning to get rid of dirt and grime, using a dilute solution of Murphy’s oil soap and water. Silicone-based cleaners and polishes are the culprits, so avoid them. Do not soak or flood the furniture while cleaning.
The most severe damage occurs from direct sunlight, melting snow and ice, or standing water. To extend the usefulness of furnishings, they should be protected from direct rain, snow, and sunshine. UV rays break down all woods eventually, and excessive moisture is necessary for fungi, mold, and insects that break down wood. It is best to keep a moisture barrier between wood furniture and the ground, as water will wick up from the soil.
It is best to bring wood furniture indoors for the winter, as melting snow can keep it damp for weeks on end. The freeze/thaw cycle can also damage joints and loosen screws. Do not drape the wood with plastic, as dew can form underneath and cannot evaporate quickly enough for the wood to dry.
Lastly, a water-proof topcoat, such as Le Tonkinois, can extend the life of any furnishings. Jacob Aune’s personal favorite is Le Tonkinois, which is easy to apply, water-proof, and holds up better than most spar varnishes available at home improvement centers.
Can backer rod be used outside?
The use of a backer rod represents a cost-effective solution for caulking tasks, particularly in situations where there is a need to seal gaps between slab siding or wide chinking joints on log homes. It produces the optimal joint configuration and reduces expenditure on caulk. Additionally, it is referred to as pre-caulking filler rope, grip strip, or backer foam. It is optimal for use in caulk joints measuring 1/4″ in width and 1/2″ or greater in depth.
What wood is most weather-resistant?
Teak, Cedar, Ipe, Cypress, and Mahogany are weather-resistant woods suitable for outdoor projects due to their ability to withstand harsh sunlight, heavy rainfall, and insects. These woods are a wise investment for those looking to enhance their outdoor spaces. Brazilian Lumber, a specialist in manufacturing and importing high-quality decking solutions, is a go-to source for tropical hardwoods and other construction materials perfect for the great outdoors. The choice of wood depends on its ability to withstand the elements, making it a classic choice among the many options available.

If I m Frank I will leave too..his partner Wolf always overpaid for their picks. Eg customer asking $100, instead of offering $50 he offered $250, stating the item worth more. Bad business point of view I m surprised Frank stayed 10 years and remain poor I suppose due to low or no profit. Frank probably made more money from his role in American picker
Rebar or no rebar, the number one thing you need to focus on when pouring flatwork is the BASE! Of course it’s faster to rush the base and add rebar, but your work won’t outlast a slab with a good base and no rebar. Focus on the base, add rebar to act as your BACK UP to if the base fails down the line.
Thanks very much for this article. I”d never attempt doing a large concrete pour myself but it helps to know this information when contracting out the job and deciding who takes shortcuts. Plus, I’ve observed a recent subdivision where the builder did not put any reinforcement in the driveways…no wire grid, rebar, etc…they built a 64 house subdivision in less than a year and if they take shortcuts in the driveway, makes you wonder how many other subpar work was done within the walls of the house.
Yet another example of how water is always your main enemy in housebuilding. Everything from mold in crawlspaces to porous brick, tile showers with no red guard sealant, bad flashing on the roof, gutter misalignment, the slope preventing drainage, not sealing basements, no air gaps behind veneer exteriors, the list goes on and on. All moisture problems. Water is scary.
Yes, so true and not only that, how does rebar get installed, is a very good subject too. Lots of driveways are poured concrete on top of rough soil and no reinforcement at all yet zero soil preparation such as sand and gravel. Most driveways are 3.5″ thick, not 4″ due to the “2×4” forms they use. Some will use fence wire to reinforce the concrete however they don’t use dobies to space the wire up off of the soil. Those who use rebar will also fail big and not space the rebar up from the soil so the concrete doesn’t encapsulate the rebar and again, no sand and no gravel prep. It’s bad enough to find a decent contractor but to spend the money and not have the right soil grade, preparations, spaced reinforcement (dobies) and so forth just says in 5 years, unless you are lucky, you will have a poor looking driveway full of cracks, gaps and uneven surfaces. There’s no good in that.
On the subject of tying separate pours. I’m considering doing an ~500sqft monolith slab in 10 incremental sections with bag product (portland) using a tow behind mixer. I’d plan to get it all done relatively quickly and keep the rebar and mesh covered. Meaning separate pours. Due to the grading and site access, every quote I’ve gotten from someone to do this location pour is ~$12k. Think that is reasonable task for one man? Mistake to tie the multiple poured sections together or a better approach? Thanks for the great content Greg.
If I wanted to build a solid slab of concrete of the same dimensions (in the article) in a freeze-thaw area (frost depth of 26″) with heavy clay, and tree roots… and I didn’t want to cut expansion joints, how much rebar would I need? Is it possible to create the same sort of floating slab with a basement beneath… with a clear span of 18’x18′?
This is a very helpful article. I am having the exact problem in my driveway. The only difference is a drain pipe that runs parallel with the concrete joints and there are drains at each joint where the corners of the concrete slabs meet. This is located immediately outside my garage doors so it is a high traffic area. I’ve gotten two different assessments from contractors and one suggested after demo and discovering whether there is erosion around the drain and checking the compacting, I would need 6 inches of concrete or 4 inches of concrete depending on what he finds after demo. He recommended rebar in each instance due to the high traffic area. The other contractor suggests 4 inches and using some type of concrete that has some built in material that substitutes for the rebar. Is there such a thing? I have never heard of it. From your article, it seems that I need rebar to avoid the problem I have. Cracking and slabs raising just as you have shown here.
My Brother’s house has a massive amount of driveway and many of the separate slabs are lifted and/or cracked. We discovered that there is zero reinforcement and no base preparation under the slabs when we demolished the worst one to replace it. I’m pouring small sections to join my asphalt to my new garage and I’m using rebar but not connected to the adjoining slabs.
Few builders do rebar anymore in footings or garages. I had a hell of a time getting the builder to place rebar in my footings. He argued politely stating it isn’t necessary and I finally said it’s my home and I want two rebar on chairs. So he did it but resented it. I’ve seen so many who do not put rebar in concrete driveways either. Unbelievable today.
Greg, thanks as always for another great article! Two questions if I may. #1 I will build a 4×19 sidewalk attached to a structure. No cars would pass on it. I thought it would be 4 inches thick. What kind of metal mesh would you suggest? Some said 10 gauge mesh. What do you think? #2 I will build 8 columns with 4 feet by 16 inches diameter sonotubes in which I’ve been told to put 2 vertical rebars. (Office foundations) My idea is to add footings under those. The calculation tells me to make a 32 inch diameter by 17.6 inches thicker footing. What kind of mesh would you put for this footing? Thanks for your eventual answer.
Thanks for the info! What if you were doing the sections over time, so at the end of the slab you left the rebar extend a foot out of the slab and when you decided to make to make the next pour, you laid out the rebar and did a one foot overlap of the rebar and welded it to the existing, that should work, do you think???
What if you were going to do a driveway in sections but didn’t want to remove all the old concrete in one shot or set up all the rebar at once? Say you removed a section of old concrete that is 1 foot bigger per side than what you want to pour. Then you rebar it with the notched forms so you will wind up with the new concrete with 1 foot long rebar sticking out the sides. Then when you do the next section you just wire more rebar on to whats sticking out to go in the next section. The reason I ask this is because my endurance isn’t what it used to be, I’m 67 and I just can’t work like I used to, this would allow me to do smaller sections. In my area it’s impossible to hire it out because of the demand.
