How to Secure an Offset Umbrella


Most offset umbrellas will not come with counter weights, in this article I will give you some solutions on How to Secure an Offset Umbrella in your patio area.  The type of base will be the first thing that will be a determining factor that will lead you to the right weights for you.

Most offset umbrella bases will be in a plus shape with a ribbed design that will secure your weights.  You can use large paver concrete slabs, they are not the best looking or a bag filled with a heavy media like sand.  Both methods will work well if used properly, the bag will look better and be safer if someone falls near the umbrella base.

Almost all offset umbrellas will not come with counter weights for a proper balance, this will be additional cost to this type of purchase.  Lets see why you need counterweights.

The design of an offset umbrella will be having an umbrella that can hang over a sitting or dining area without a central pole.  The pole will be on the side with an arm that will extend out for the umbrella to hang from.  The advantage of this type of umbrella is that you do not have an obstruction in the middle of the table.  The other case is that you do not have a table with a hole for an umbrella, like a conversation set.  Most coffee tables will not support a market umbrella.

With the offset design, the base of the umbrella will have to be secured to the ground with weights or permanently mounted secured to a ground surface.  If you do not have weights or not secured to the ground your umbrella will not be stable when opened.

Now lets look at the kinds of weights available to secure your offset umbrella for use.  If you would like to look at some of my offset umbrellas, see my post here.  I even have a review of an offset umbrella with a screen to keep out bugs, see an article here.



Kinds of weights


Two major types are available today, stone weights or media filled weights.   Each can stabilized your offset umbrella by sitting on the arms of the base.  The amount of weight that you need will be in the manufactures recommendations.  Your results will may vary with each of these solutions, follow the instructions for your umbrella.

This four piece set will give you up to 140 pounds of weight to counter balance your umbrella.  Each piece made form a heavy duty plastic material, will hold 4.2 gallons of water that will be filled through a fill spout.  At 8.3 pounds per gallon this will give about 35 pounds for each section.

When these four sections are put on the cross type base they will make a almost square pattern.  The top of each piece will have a decorative design.  The base will be 20 inches from the corner, 20 inches from outside corner to outside corner and 3 inches thick.

The big issue with this type of counter weight is the water fill.  When the weather turns cold, under 32 degrees, they will have to emptied to avoid being damaged beyond any further use.  With a little work, you could fill this umbrella base with a medium like sand, this may take a little time with the small hole for filling.

What do I recommend for you


Depends on your method on How to Secure Your Offset umbrella, each of these bases can work.  I prefer the sand filled models for the better look, they are safer with no sharp edges and you do not have to empty during freezing weather.  I have filled my media umbrella base with sand for years without having one of them fail because they spit from freezing weather.

If you spend good money for an offset umbrella, I would go with a filled base for the extra safety and the ability of ease of movement.
