Pointers on anchoring, what kind of things will impact holding power of anchors,
anchoring after moving a structure
A phrase Norm has used thousands of times in his career is, “There is no such thing as too many anchors.” We consider it important to help customers understand the aerodynamics involved with a greenhouse shape.
The relatively small cost of the anchors is a short-lived savings after a building has blown away or shifted. By understanding and implementing what is required you can ensure a long term usage of your structure.
The job of your anchoring system is to counter the three aerodynamic forces working on your building.
The first thing you will need to assess is what you are actually working with. If you have bedrock close to the surface, you have large rocks, or you have straight sand, it will impact your options for anchoring.
The actual holding power of your soil is an important consideration. Soil that has been recently excavated has considerably less holding power than soil that has not been moved in a long time.
The total surface area of an anchor post in contact with the soil is an important consideration. Large and short may have more contact area than long and slender.
When anchors can be used in alternating directions, it will multiply their individual holding power.
Wet soil usually does not have the same holding capacity as well drained soil. An important consideration here is rainwater which is shed by the building. As an example, with a 16’ wide structure, 8’ of rainwater goes each way. This means that the narrow area next to your building get 8 times the rain that the rest of the property gets. If you have poorly draining soil, this could be a potential problem.
If you are planning to use the movable structure option, proper anchoring has some additional challenges. Since your building is vulnerable to sudden increases in wind during this process, your anchoring protocol needs to be done quickly. Always do a test in the new area to confirm what you will be working with. With the quickness that is required, there is also a reminder that taking shortcuts will come back to haunt you.
We would like to reiterate, “If you are not 110% sure, please ask” There is no situation out there that is so unusual that we have not already been through it.
Your long term success is very important to us!
We hope you are finding value in this series of posts, helping you prepare for your new growing adventure! Reminder that the deadline is May 31st for Fall Delivery. We look forward to working with you for your projects!
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:
Anchor Posts SHOULD NOT be used (and base brackets used instead) when:
Recommendations are based on years of experience. Ultimately the customer is responsible to properly anchor a structure
