Picking the wrong concrete grade for your garden shed foundation might seem minor, but it’s what separates a stable base from cracks that invite weeds and water. For light structures like a small greenhouse or tool shed, a basic C10 mix often works, while heavier projects call for C20 to handle moisture and load without crumbling. The key is matching strength to your soil and local weather—too soft and you get settling, too hard and you waste money on overengineering.
