Anchoring: Base Brackets vs Anchor Posts

edit-Base Bracketanchor post photo

We offer two main types of anchoring for our structures: Base Brackets (left pic) and Anchor Posts (right pic).

Which one you decide to go with largely depends on your application and location. They are not to be used together, it is a one or the other option. No matter which option you choose, please be aware, there is no such thing as too many anchors!

Although the building can be anchored directly into the ground with Anchor Posts, it can also sit on a slab, curb or beam or it can be elevated on some sort of a wall. Base brackets with lag bolts are supplied standard to fasten the building to the chosen form of foundation. Anchor Posts are available at an additional cost.

Anchor Posts must be set into concrete when:

  • the soil has been recently excavated (within the last 5 years)
  • it is required by the building code (use of concrete usually classifies the building as permanent)
  • extremely windy and exposed areas exist (at least use on the corner posts)
  • more than 10% of the anchor post will be out of the ground (upgrading anchor post size may be needed)
  • there are areas where erosion has been a problem in the past

Anchor Posts SHOULD NOT be used (and base brackets used instead) when:

  • the soil is a very heavy clay (heaving would be a constant problem)
  • there is a shallow rock layer
  • there are major amounts of rocks interfering with the accuracy of anchor post setting
  • the structure will be moved shortly (anchor posts must be cleaned out before reusing)

**Recommendations are based on years of experience. Ultimately the customer is responsible to properly anchor a structure**

Greenhouses 101: Climate and Air Effects on your Structure

You might be wondering, How does air volume affect the climate in a greenhouse? There also is the matter of air changes. What is the connection between shape and aerodynamics? You need to make sure it stays put.

There are 3 forces on every building which need to be considered if you want it to stay where you put it and in the shape you built it. There is down force (usually from snow build up), up lift (by wind) and lateral shift (both wind and snow). Mother nature is not restricted by lack of patience and will work away at any vulnerabilities in the structure, often without notice until it’s too late. There must not be any wiggle room that the weather can work on these vulnerabilities or things will come loose, unstable, and wear out faster..

There simply is no such thing as too many anchors. There are also various tips we can give you for ensuring that the plastic is tight enough to avoid wrinkling and flapping about, while balancing the issues of it being too tight. This can easily extend the life of your roof cover.

We also advise, especially this time of year, to cover the structure as soon as you can as the more snow you have on that spot which has to melt, the more moisture you will have in the building. The more moisture you have in the building the more condensation issues you will have. You want to give that ground the most time possible to dry up before you need to start using the building.

Contact us for more tips and considerations for building a structure that will stay put and have a longer life, we would be happy to help you.
