When pouring a garden foundation, the concrete grade you pick directly impacts its durability against weather and ground movement. A standard C20 mix works for light sheds, but for heavier structures like a brick planter or greenhouse, upgrading to C25 or C30 provides better load-bearing capacity and frost resistance. Checking the soil type and local conditions before buying helps avoid cracks later.
