How many helical piers are required for a deck?

This depends on the size of the deck- the bigger the project, the more piers will be required. The rule of thumb is to maintain a spacing of 8 to 10 feet (2.4 to 3 meters) between the piers. It also makes a difference whether the deck is attached to an existing structure or free-standing.

If the deck were attached to a house, it would require fewer piers since the existing structure would take on a portion of the load. However, for a free-standing deck, more piers would be needed.

Examples:

- A 10' x 10' deck that is attached to a house needs 2 TMP helical piers.

- A 10' x 10' free-standing deck needs 4 TMP helical piers.

Before starting your project, please don't hesitate to contact a professional to obtain more information and ensure you comply with construction standards.
