Water Weights for Anchoring Inflatables: A Practical Guide

By Happy Jump®, Inflatable Manufacturer Since 1998

When it comes to inflatable safety, anchoring is non-negotiable—and at Happy Jump®, safety has been our top priority since 1998. anchoring is non‑negotiable. Whether you're setting up a bounce house, water slide, or interactive game, proper anchoring keeps guests safe, protects your equipment, and helps you comply with manufacturer and insurance requirements. One of the most versatile anchoring solutions—especially on hard surfaces—is water weights.

In this guide, we’ll break down what water weights are, when to use them, how much weight you need, and best practices for safe, professional setups.

What Are Water Weights?

Water weights are heavy‑duty containers (often vinyl or PVC) that are filled with water on site and attached to inflatable anchor points. Once filled, they provide significant downward force to help keep inflatables stable when stakes cannot be used.

They are commonly used for setups on:

• Concrete

• Asphalt

• Indoor floors

• Artificial turf

• Any surface where staking is not allowed or possible

Why Use Water Weights Instead of Stakes?

While ground stakes are ideal on grass or dirt, many events take place on hard or restricted surfaces. Water weights offer several advantages:

✅ Surface-Friendly

No drilling, hammering, or surface damage.

✅ Portable & Convenient

Empty during transport, heavy only when filled on site.

✅ Versatile

Ideal for indoor events, parking lots, school blacktops, and city venues.

✅ Professional Appearance

When properly positioned, they keep setups clean and compliant.

How Much Water Weight Do You Need?

This is one of the most common—and most important—questions.

General Rule of Thumb

Most inflatable manufacturers recommend:

75–100 lbs of anchoring per anchor point

However, the exact requirement depends on:

• Inflatable size and height

• Wind conditions

• Type of unit (bounce house vs. tall slide)

• Manufacturer specifications

Example Calculation

If a unit requires 6 anchor points and 100 lbs per point:

• 6 × 100 lbs = 600 lbs total anchoring

That could mean:

• Six 100‑lb water weights

• Or twelve 50‑lb water weights (paired per anchor)

⚠️ Always follow the manufacturer’s anchoring guidelines when available.

Best Practices for Using Water Weights

1. Attach to Proper Anchor Points

Only connect water weights to designated D‑rings or anchor loops—never to seams or netting.

2. Use Non‑Stretch Straps or Ropes

Ratchet straps or heavy‑duty ropes help minimize movement.

3. Keep Weights Close to the Unit

The closer the weight is to the inflatable base, the more effective it is.

4. Distribute Weight Evenly

Every anchor point must be secured—skipping even one increases risk.

5. Monitor Wind Conditions

Water weights do not replace weather monitoring. If winds exceed safe limits, deflate the unit regardless of anchoring.

Water Weights and Wind Safety

Anchoring—no matter how strong—does not make an inflatable windproof.

Industry safety standards generally recommend:

• No operation above 15 mph sustained winds

• Immediate deflation during gusts or storms

Water weights are a critical safety component, but they must be used alongside:

• Proper supervision

• Wind monitoring

• Clear shutdown procedures
