Installing a dedicated concrete mount provides cantilever umbrellas superior stability compared to portable bases. By securely anchoring into an immobile concrete pad, the umbrella remains fixed and steady against wind and heavy use without toppling over or shifting unexpectedly. While seeming complex, this guide breaks the cantilever umbrella concrete mounting process down into six straightforward steps that anyone can tackle.
Concrete mounting reinforces cantilever umbrellas in several impactful ways:
- Prevents tipping from wind gusts up to 35 mph
- Allows smooth 360deg rotation even in off-center installations
- Low profile pad keeps walkways obstruction-free
- Steel mount plate withstands corrosion and rust
Step 1: Choose Mounting Location
Selecting the right concrete mount site takes some forethought. Consider available space, desired umbrella coverage, sunlight patterns and visual appeal when deciding on placement. The pad must be:
- At least 20% wider than the umbrella canopy’s diameter
- Have sufficient clearance around structures, seating areas and traffic paths
- In a spot allowing the canopy to shade the intended gathering area
Also, account for any slope or unevenness in the installation surface. A level pad prevents leaning and enables easier pole adjustment.
Durability Considerations
The cantilever umbrella mount location should withstand various environmental factors over years of use:
| Wind and Rain | Withstand 35+ mph winds and seasonal precipitation |
| Sun and Heat | Resist UV rays and expand/contract with temperature changes |
| Frost and Snow | Prevent freeze/thaw heaving and carry snow load |
Step 2: Determine Appropriate Base Size
Most cantilever umbrella manufacturers recommend a minimum 300 lb pre-cast concrete pad for secure mounting. Larger umbrellas need an even more massive base – up to 700 lbs for 13 ft canopies. Use this general sizing chart for poured concrete pads:
| Umbrella Size | Min. Pad Weight | Pad Dimensions |
| 10 ft – 12 ft | 300 lbs | 20 in x 20 in x 12 in |
| 13 ft | 700 lbs | 24 in x 24 in x 12 in |
Including rebar or mesh grid when pouring the pad prevents cracking over years of tension from umbrella raising/lowering.
Versatility Factors
Consider adjustable or universal cantilever mounting brackets to accommodate future umbrella upgrades or seasonal removal:
- Accommodate umbrella heights from 88 in – 124 in
- Rotate smoothly even when off-center
- Detach without damaging concrete pad
Step 3: Pour or Install Concrete Base
Now that the specifications are determined, installing the concrete pad itself comes next. Contractor-poured footing pads start around $1,200 – $1,800 installed. However, DIY concrete pouring proves a more affordable option if willing to do the labor.
When pouring your own pad:
- Assemble concrete forms level on ground
- Mix and pour 5000 psi concrete 2 inches at a time
- Work gravel under pad for added drainage
- Let concrete fully cure for 2+ days before mounting
Step 4: Bolting Cantilever Mounting Kit
With the concrete base ready, securely attach the steel umbrella mount components. Typical cantilever mounting kits include:
- Zinc-plated steel attachment plate
- 4 x 3/8 in concrete sleeve anchors
- Anchor bolts, washers, wrench
Use a hammer drill and proper bit sized for anchors to affix the mounting plate. Recessed installation helps avoid tripping hazards. Tightening everything to the specified torque ensures wobble-free cantilever support for years.
Ease of Installation
Reputable umbrella makers supply user-friendly cantilever mounting hardware matched to their pole sizes. With all parts and easy instructions included, homeowners can tackle self-installation without added contractor expenses.
Step 5: Attaching Cantilever Pole
The last step involves connecting the umbrella pole into the now secured concrete mount. Simply slide the pole end over the attachment plate brace, centering it into position. Adjust rotate and tilt tension knobs until the pole aligns plumb.
Before raising the umbrella, confirm that the pole:
- Spins freely 360deg around concrete mount
- Locks securely into tilted angles
- Supports canopy without leaning
Step 6: Finishing Touches
Once assembly completes, add some subtle refinements to complete installation:
- Caulk around mount plate/concrete
- Test raising/lowering umbrella
- Touch up paint scrapes if needed
Then start enjoying worry-free shade from your smooth pivoting, wind-resistant cantilever umbrella for years on end!
Beyond exceptional function, concrete mounted cantilever umbrellas add beauty and design flair to backyards and patios with their graceful shapes and arcs overhead.
