When dealing with deck additions and renovations one point is extremely difficult to address: the excavation needs to support the code rules to have a stable and strong foundation.
Decks causes of failure can vary from a bad connection with the house to a foundation block or post that is not designed to support that amount of weight. And to have a good foundation we have to dig a hole with huge machines sometimes. Not anymore.
Pin Foundations, Inc., manufacturer of the Diamond Pier, has been designing and manufacturing foundations for over 25 years. And their idea to design a better product is that the Earth is the actual foundation, and soils, in their natural undisturbed state, have the strength and structure to do the job.
That’s why they designed Diamond Pier based on Pin Pile Technology. Pilings keep the Earth’s existing soil strength and structure intact and are easy to install if they do not need to go too deep. Traditional footings spread loads more widely, but the digging breaks apart the soil, weakening it and blocking or exaggerating water flow.
By grouping short bearing pins, which can easily be driven into intact penetrable soils, and setting them at angles to work more like a shallow footing, a sound foundation can be constructed that requires no excavation. This high-strength, precast component is a driving guide, a pin piling lock, and a structural connection all in one.
As a driving guide, the pier maintains the pin angles so that their capacity is definable and consistent. As a lock, the pier is designed to increase its grip on the pin cluster when loaded up, down, or side- ways—getting stronger and tighter as loads increase. And as a connection, an embedded anchor bolt and precast, post-matching shape make it a simple and proportional complement to its supported structure.
The Diamond Pier provides a solid, stable, economical foundation that both captures and preserves the supporting strength and natural functions of the Earth’s soil and, in turn, solidly and simply connects to and protects the permanent structures above.
The only limitation we have to use them appears when we deal with a rocky soil.
