We often get asked this question and there is no "one size fits all" solution. Every tank installation is different and dependent on where the tank is going to be situated. Some points to think about when deciding on the right roof loading for you:
Below are some rough rules around what each of the roof loadings mean. Please be aware as mentioned above, this is not a one size fits all but it gives you an idea of some of the more popular requests we receive:
Roof showing – Holds 1.5 tonne – Pedestrian loading but NOT crowd loading
3KPA roof loading – Holds 3 tonne – Equivalent of 400mm soil loading on top
5KPA roof loading – Holds 5 tonne – Able to have a small vehicle drive over the top
40KPA roof loading – Holds 40 tonne – Able to have heavy vehicles drive over the top
There are many other options available such as building a shed over the top, burying with more soil or even a gazebo. For more information, please give us a call to discuss the right option for you!
