Plans for using your bounce house for a party or celebration may become sidetracked for a variety of reasons. The common culprit for these delays is poor weather, which can strike your party area through heavy rainstorms, thunder and lightning, strong gusts of wind, and low wind-chill temperatures. However, your day is not ruined. Having a bounce house party indoors is a worthy alternative that constantly grows in popularity and preference each year. To set up an inflatable device under a solid roof, you’re going to need sandbags to secure the bounce house to the ground, thereby avoiding possible collapse and injuries.

These sandbags intended for indoor bounce house use help to stabilize your inflatable device and hold it in place during jumping. The bags are most commonly made from polyvinyl chloride (PVC), also known as the same material used to construct most bounce houses. These sandbags are very hard to damage and are likely to last a long time, usually as long as the bounce house itself. The majority of sandbags that you can purchase for your bounce house have a weight capacity of about 50 pounds. This means that if you have a sandbag for every corner of your bounce house, it will take about 200 pounds of sand in order to evenly secure the inflatable device to the ground. However, for inflatable devices on a larger scale, such as obstacle courses, the amount of bags necessary for fastening will likely increase to six or even eight. It all depends on the amount of tie-down loops present on your inflatable device’s base.

Outside, you would pound stakes into the ground through these loops in order to lock down the bouncer. Inside, you tie the sandbags to these loops to keep the bounce house steady and unmoving throughout the day. Typically, the sand to fill the bags will not arrive with the bags themselves; you will need to buy it separately from a home improvement store. Your inflatable device may not need all 50 pounds of each bag to remain firmly to the ground. The definite weight of sand needed to fix the bouncer’s position may vary depending on the type of bounce house you have. We recommend testing this by filling each sandbag with varying levels of sand, then checking if the bounce house will remain secure. Usually, though, it’s a good idea to fill these bags up at least halfway.

When you feel you have added an acceptable level of sand in your bag, you must then completely seal it using the zipper on the mouth of the bag. Make sure that the zipper is absolutely tight and secure before tying it to the bottom loops of the bouncer. If the zipper is not sealed tight, then grains of sand can begin to leak out of the top of the bag during use. This could cause the bounce house to come loose from the set-up area. If leaks in the bag are spotted, either from a loose zipper or from a tear in the bag itself, cease bouncing temporarily while the bag is being replaced.
