It is not recommended to bury the Dek-Block® pier more than 2 inches for climates that have seasonal frost. Areas that are without frost (such as Arizona, Florida, Southern California and Texas) can bury the Dek-Block® pier if needed up to 4 inches. Be sure to leave at least 2 inches of the Dek-Block® pier exposed between the ground and where the support board will be sitting. This will allow for air flow in preventing rot and insect attraction.

If the Dek-Block® pier were to be buried in climates where frost occurs, the Dek-Block® pier will slowly creep up and out of the ground over time. Take a look at what occurs with frost heave.

Anytime the Dek-Block® pier is buried, verify there is proper drainage away from the pier and hole. Otherwise, you will have a small hole to collect water under your deck.
