You know those wooden or metal manhole covers? They are heavy and bulky! Pronal offers you an inflatable formwork with multiple advantages. We let you discover them in this article 🙂
What is an inflatable formwork ?
The inflatable formwork, called JB Qualifix at Pronal has the same principle as the rigid formwork? However, instead of being made of metal, ours is manufactured from polyuréthane et welded by high frequency. Therefore, the product is flexible and light.
This product is placed inside the manhole. Once it is inflated, the operators can pour the concrete all around.
So, what does it have more than the standard solution ?
The multiple advantages of the inflatable formwork in comparaison of the rigid one
A quick and easy installation
One of the most important advantages is: how easy it is to use this product. Even if it is new and that is the first time you ever try it, we promise you that you will understand how it works very quickly.
- outside the manhole: pre-inflate the inflatable manhole and place it inside the manhole using its handling handle
- inside the manhole: once it is correctly placed, inflate it
And that’s it !

A perfect watertightness
Assembled by high weld frequency, the inflatable formwork has a perfect watertightness. Therefore, it prevents the fall of residu in the manhole during the concreting. Thus, the operators don’t have to go down to clean the manhole.
A light product
Manufactured from polyurethane, the product is very light: no need for handling equipment, only 2 arms ! Therefore, its transportation is very easy !
A time saver
thanks to its easy installation, its weight and its perfect watertightness, the inflatable formwork saves 5 hours of work on site !
Prevention of the FME risk
At the beginning, the creator of the JB Qualifix (Johnathan Bracco) thought of this product mainly to ensure the security of his workers. Indeed, this inflable formwork enables the prevention of the FME risk: it prevents any fall of objects or operators. Therefore, the workers are now protected during the entire time of the sealing.
A reusable product
After every utilization, you have to clean the product and take away every residu of concrete. Then, the product could be reused at least 50 times !
