Greenhouse Foundation

The foundation is the part of the structure that transfers the greenhouse load to the ground. The foundation and flooring are the most important parts of greenhouse construction. First, the slope of the land is examined. If the land area is large, surveying is usually conducted for such projects, and necessary actions are taken to level the ground.
One of the most durable foundations is the concrete footing. Concrete foundations can bear heavy loads.

Types of Foundations:

  • Point Foundation (Individual/Concrete Footings at Base Points)
  • Pits with a depth of 50–80 cm are dug
  • Suitable for small, tunnel, or movable greenhouses
  • Strip Foundation (Concrete Strip under Walls)
  • Suitable for semi-industrial and industrial greenhouses (heavy structures)
  • Full Concrete Foundation (Reinforced Concrete Floor)
  • Suitable for special greenhouses with industrial flooring, windy areas, or long-term projects
  • The most durable type of foundation

Materials Used in Foundations:

  • Concrete (usually C20 or C25)
  • Rebar (10 or 12 mm)
  • Flange or steel base plate
  • Square tubing, pipes, or ground screws

Depth and dimensions of the foundation depend on:

  • Wind speed in the area: Higher wind → greater depth and strength required
  • Type of greenhouse: Lightweight tunnel → simple point foundation / Gothic or steel → strip or full foundation
  • Soil type: Hard soil → shallower foundation / sandy soil → deeper foundation required
  • Project lifespan: For temporary projects, a lightweight foundation is sufficient
