As a marquee owner, weather conditions can greatly affect the integrity and safety of your structures. Windy conditions pose significant challenges that can lead to potential damage or even pose hazards for your events. Understanding how to adequately protect your marquees in windy conditions is crucial for ensuring safety, protecting your investment, and maintaining a good reputation among clients.

Understanding the Risks

Wind can significantly impact marquees, especially large ones. High winds can create pressure points that strain the fabric and structure of your marquee, leading to tearing, collapsing, or being lifted off the ground entirely. It’s vital to assess the site and wind conditions before setting up your marquee to determine whether it’s safe to do so.

1. Site Selection Matters

Choosing the right location for your marquee can make a world of difference. Ideally, your marquee should be set up in a sheltered area, such as behind buildings or large trees that can act as windbreaks. Always survey the site for potential risks like falling branches or debris that could be propelled by strong gusts.

2. Use Proper Anchoring Techniques

One of the most critical aspects of protecting your marquee is ensuring it is anchored correctly. Utilize high-quality stakes, weights, or ground anchors designed for windy conditions. Larger marquees may require additional bracing or heavier weights to withstand strong winds. Consult the manufacturer’s guidelines for specific recommendations regarding anchoring based on your marquee size and type. Typically at DIY Marquees we recommend a minimum of 100kg per leg or a 50cm J stake and ratchet strap on soft ground.

3. Regular Maintenance and Inspections

Before setting up for an event, always conduct a thorough inspection of the marquee. Check for any signs of wear and tear, such as frayed fabric or loose fittings. Ensure that all support poles and connectors are secure and in proper working order. Regular maintenance will help you catch any potential issues before they become larger problems, especially in windy conditions.

4. Use Wind-Resistant Designs

Consider investing in wind-resistant marquee designs if you frequently operate in areas prone to high winds. DIY Marquees incorporate several wind-resistant designs such as a 20 degree pitch roof, this reduces load on the marquee by reducing the overall height and allowing wind to flow over more easily.

We also use gable uprights at the ends of the marquee. This extra framework allows the end panel to be split into multiple sections and prevents billowing in windy conditions.

Lastly our “wind-stop” Velcro seals the side panels, removing any gaps and preventing wind blowing between the leg covers and into the marquee.

5. Monitor Weather Conditions

Use smartphone apps that provide real-time weather updates. This will allow you to stay informed of changing weather conditions and make timely decisions regarding your marquee. If forecasts predict high winds, consider removing the covers from your marquee or disassemble the marquee completely.

6. Plan for Quick Disassembly

In extreme wind conditions, having a plan to quickly disassemble your marquee may be necessary to prevent damage and ensure safety. Train your staff on emergency procedures and have the right tools readily available for a fast response.

7.Final note

We’re often asked if it’s better to leave the sides on the marquee or take the off to allow the wind to “pass through”. It’s always better to keep all sides on the marquee and zipped up. Having a roof-only structure creates lift, much like an aeroplane wing with faster air flowing underneath. Therefore it’s best to keep all sides on and anchor the marquee well, or completely remove the structure.

As a marquee erector, the ideal scenario is setting up on a perfectly level surface, like a bowling green where you can park your vehicle right next to it. However, you may encounter customers who dream of transforming their three-tiered, sloped, and bumpy garden into a banquet-worthy space.

So, how do you handle this?

1. For Beginners:
   • If you’re new to the marquee hire industry, don’t worry too much. Most gardens are relatively level, and extremely bumpy surfaces are rare. If a customer has a sloped but otherwise flat garden, assess whether it’s suitable for placing tables and chairs by asking if they’re comfortable using their garden furniture on it. If they are, it’s likely fine for your marquee setup. Avoid using chocks to level table legs as this can create an uneven dining experience.
2. Addressing Small Bumps and Holes:
   • For minor bumps or holes, you can fill them in and lay your floor over the top. Bark was once a common choice, but it can be spongy. Sand or old newspapers work well. Always lay down plastic sheeting underneath your fill material to make cleanup easier.
3. When to Walk Away:
   • If the ground is severely uneven, and filling small holes isn’t sufficient, consider walking away if you don’t have access to an integrated wooden floor system (available with large aluminium frame marquees). It’s tough, but sometimes it’s not possible to create a suitable surface. Remember, we’re marquee erectors, not miracle workers.
4. Final Checks:
   • When laying flooring over uneven ground, ensure you fill any holes you find before finishing. Covering a hole without filling it can create a tripping hazard for guests.

Navigating uneven surfaces can be challenging, but with these tips, you can manage most situations effectively.

Bungee Stretch

Bungees are designed to stretch in windy conditions to prevent damage to the marquee’s roof or side panels. However, over time, they can become worn and resemble string, especially on the side exposed to the most wind. It’s essential to replace these bungees when they show signs of wear. Avoid using cable ties for replacements, as they can cause eyelets to rip.

Stakes & Straps

If your marquee has been up for an extended period or has experienced heavy rain, it’s crucial to check your stakes. Ensure they are still securely anchored and haven’t shifted or been dislodged. Additionally, verify that the straps are tight and in good condition.

Water Pooling

For marquees that have been erected for a long time, inspect the roof for any water pooling. Standing water can stretch the PVC material, leading to potential damage to this critical part of your marquee. Address any pooling promptly to prevent damage.

Cleaning the PVC

The best time to clean the PVC is while the marquee is still up. We recommend using TFR (Traffic Film Remover). Dilute the TFR, spray it onto the marquee, and scrub with a stiff brush or broom. Rinse thoroughly with a hose to leave the marquee clean and fresh.

This one should be relatively short and sweet; just like snowfall in the UK!

The first think you need to know is that no marquee however big or strong is designed for snow-loading. The weight of all that frozen water is just too much!

The second thing you need to know is that there are two main ways to prevent any damage to you structure.

1. Keep an eye on the weather forecast and dismantle the marquee before an excessive amount of snow gets the chance to form on the roof
2. Use a heater to warm the marquee while the snow is falling to prevent any from forming on the roof. If it’s warm enough the snow will melt right off.

Types of marquee heaters to use:

• Indirect diesel/oil fired heaters (the best ones)
• LPG Blower/Space Heaters
• Ducted Heaters

Note: Don’t use electric or patio heaters; they’re not man enough!

I once saw two guys at a country fair fitting signs onto the top of a large marquee. The marquee was around 30 meters wide, and these guys were walking along the ridge, about 10 meters up, bouncing on the PVC roof sheets as they went. While I won’t delve into their risk assessments, this highlights an important point: marquee PVC can stretch over time, regardless of the size.

So, what can you do about it?

Here are a few tips:

1. Keep the PVC Taut:
   • Ratchet Straps: If your marquee uses ratchet straps, be aware that they might need adjusting periodically. Ratchet straps can stretch slightly over time, so check and tighten them as needed.
   • Bungees: Marquees with bungees, like ours, might require bungee replacements as they wear out.
2. Adjust the Framework:
   • Bolted Pipes: We use bolts to secure our pipes rather than push buttons. This design allows for adjustments if the roof stretches over time. By pulling the pipes slightly out of their sockets before tightening, you can make the framework wider, which helps stretch the roof tighter and prolongs the marquee’s lifespan.

By following these steps, you can ensure your marquee remains in good condition and lasts longer.

A common question is how long a marquee can remain erected. This involves two key considerations: the structure of the marquee and the state of the ground.

1. Marquee Structure:

Marquees are designed as temporary structures. For long-term use, you should:

• Inspect Regularly: Check for wear and tear, the condition of bungees, and any signs of damage.
• Maintain Cleanliness: Ensure no water or snow accumulates on the roof.
• Avoid Extreme Weather: Try not to leave the marquee up in severe weather conditions.

2. Ground Conditions:

The ground can be a concern, especially if the marquee is on grass:

• Grass Coverage: As noted in a recent forum post, covering grass for an extended period can lead to rotting grass beneath the groundsheets, which can produce an unpleasant odor. This smell usually only becomes noticeable when the flooring is removed, not while the marquee is in use.
• Short-Term Use: Flooring can be down for a week or two with minimal impact; the grass might yellow slightly but will recover after a few weeks.
• Long-Term Use: If the marquee remains up for longer, the grass is likely to die off and may require re-seeding.

Avoid Breathable Flooring/Matting: While marketed as ‘breathable,’ this type of flooring can trap condensation and allow grass to grow through the mesh, which I personally find problematic and why we don’t offer it.

By following these guidelines, you can help ensure the marquee remains in good condition for the duration of its use.

When planning a marquee event, it’s essential to allocate enough space for furniture and features. Here’s a basic guide using 3x3m squares:

• Round Tables:
• For an 5ft round table seating 8-10 guests or a 5ft6in round table for 9-11 guests, allocate one 3x3m square.
• Buffet Tables:
  • For a set of buffet tables (usually three 6ft trestles), allow 3x6m (equivalent to two 3x3m squares).
• Top Table:
  • For a traditional long table or an oval top table, allocate 3x6m.
• DJ Area:
  • Allocate 3x3m.
• Band:
  • At least 3x6m, depending on the number of band members.
• Bar:
  • Allocate 3x3m, often with an additional 3x3m for seating or sofas.
• Dance Floors:
  • Dance floors vary in size based on the event and guest count, so these are more flexible. Consider the space needed based on your event specifics.

Additionally, it’s wise to leave some clear space at the entrance and in front of any catering areas, if possible.

For a more tailored plan, you can use our marquee planner or email us, and we’ll help you put everything together.

A high-quality marquee with interchangeable side panels offers your customers the flexibility to choose where the windows are placed when the marquee is set up.

However, this flexibility can also be a challenge. Your customer’s preference for window placement may differ from your own suggestions. It’s important to engage in a diplomatic discussion with them. Ultimately, they should have the final say, though you can offer recommendations and explain the reasoning behind them.

Generally, windows should be oriented towards the best view. Any sides facing barriers like walls or fences should be covered with solid panels. While some customers may prefer windows facing the sun, which can result in glare, it’s usually manageable and not a major issue.

For the most aesthetically pleasing appearance, windows should be arranged symmetrically. For example, if a marquee side has six panels and your customer wants four windows, place the four windows in the center with walls on either side. Symmetry is crucial for the exterior appearance of the marquee, although it’s less critical from the inside, especially if partitions are involved.

Finally, placing some windows near the entrance enhances the marquee’s inviting atmosphere, regardless of the view.

Determining how much anchoring a marquee requires isn’t an exact science and is largely based on experience, with a tendency to err on the side of caution. While standard tie-down kits offer one tie-down per leg, factors like ground softness, nearby wind-breaking structures, location, weather, and whether the marquee has sides will influence how much anchoring is needed. In difficult conditions such as soft ground or strong winds, additional anchoring points may be necessary. Portland Marquees provides robust tie-down kits with larger stakes and stronger ratchet straps for added security.

When you have to position a marquee side-on to a house and don’t have the luxury of using a walkway, things can get a bit tricky. While a proper walkway (especially one of ours!) makes the process much simpler, there are ways to make do with what you have. Here are a couple of options to consider when weathering a marquee to a house in these situations:

Option 1: Butting the Marquee Directly Against the House

This approach is similar to last week’s method, where you push the marquee up against the house. However, the challenge comes with the type and size of doors you’re working around:

• Sliding Patio Doors: These are the easiest to deal with. You can butt the marquee up to the house at any height and simply use guttering to weather the join. However, you might encounter a step down into the marquee, and there’s a chance people could bump their heads on the eave rail or gutter.
• Inward-Opening Patio Doors: These can be treated similarly to sliding doors, allowing for a fairly simple connection between the house and marquee.
• Outward-Opening Patio Doors: These are the most common and the most problematic. Here, you have three options:
  1. Use a walkway (I’ll cover this in next week’s post).
  2. Create your own makeshift walkway (see Option 2 below).
  3. Lift the marquee up over the doors. If you’re using one of our deluxe marquees, there’s a good chance it’s tall enough to clear the doors. However, with a standard commercial marquee, you may need to “chock it up” using bricks or extensions to raise it slightly. This should be a last resort since marquees aren’t designed to be propped up, and changing the angle of the roof can affect how water runs off.

Option 2: Creating Your Own Walkway

If the house has outward-opening doors, you can try making a temporary walkway yourself:

1. Open the Doors to 90 Degrees: Open the doors so they are perpendicular to the house.
2. Place a Wooden Plank Across the Top: Lay a piece of wood across the top of the doors. Ideally, you want to use chocks to hold the doors in place and angle the plank slightly so that any rainwater runs away from the house.
3. Butt the Marquee to the Walkway: This makes a very short and easy DIY walkway, allowing you to weather the marquee against the house with minimal fuss.

Final Thoughts:

While these methods can help you get by, the best solution is still the one I discussed last week: positioning the end of the marquee directly against the house. If that’s not an option, investing in a decent walkway will save you time and effort and give a more professional look.

Thanks for reading, and stay tuned for next week’s post on walkways!
