No Rot. No Rust. No Problem.
Pearson Pilings - Driven to Last


Q1. Are your fiberglass pilings really stronger than wood, steel or concrete?

A1. Yes, a materials stress test comparing similarly sized pilings clearly shows the superior strength of fiberglass composite pilings over wood, steel or concrete.

Q2. How long will your pilings last in salt water?

A2. We expect the life of our pilings to be 100 + years whether in salt or fresh water. Many of the fiberglass sailboats we built 50 years ago are still afloat, and the resin systems we use today are much more robust.

Q3. Is there any maintenance required on your pilings?

A3. No maintenance is required unless there is EXCESSIVE wear due to rubbing, chafing or the high impact of boats, dock hardware, hoops and etc. There will be no structural damage to the piling if the PPT exterior layer is destroyed, but you do not want to allow the fiberglass wall to be damaged by excessive chafing.

Q4. What is the cost difference between your pilings and wood, steel or concrete pilings?

A4. If you compare only the cost of the piling itself, our fiberglass composite pilings are more expensive than some and less than others. BUT there are many other factors that make our pilings a much better investment. To begin with, the superior strength and resistance to shifting of our pilings often results in having to use fewer pilings in a given project. Also consider that our pilings last virtually forever and require no maintenance. Under normal wear, you will not need to replace them in 15, 20, 30 or more years. If you are replacing old, deteriorated pilings, our pilings can often be driven over the existing ones, saving demolition and removal costs. And lastly, the weight of our pilings will reduce the handling and installation for the contractors. In the long run, using our pilings is more economical and a better investment than using wood, steel or concrete.

Q5. What should the typical life cycle cost of a pier be based on?

A5. The life cycle costs of the pilings should be based on at least an 80-year life, compared to 15-years or less for other products in certain areas. The life of the rest of the pier's components will depend on the material used. More and more piers and docks are being built with composite decking materials that have a longer life cycle than traditional materials.

Q6. Can I use composite pilings for a house foundation designed for wood pilings?

A6. Absolutely. Your foundation will be stronger than wood, at least as strong as steel and will last virtually forever. The skin friction of our composite pile is approximately the same as a steel pipe, but significantly higher than wood. The total capacity of the composite pile is higher than wood and approximately the same as steel. The lateral capacity of a composite pile equals that of a comparable steel pile and a few times higher than that of a comparable wood pile.

Q7. What is the exterior coating?

A7. Toughened acrylic paint system for Ultra Violet radiation protection

Q8. Will barnacles grow on these pilings?

A8. Yes, barnacles will grow on anything, but they can be scraped off relatively easily if not allowed to grow and accumulate over time. Of course, PEARSON PILINGS are impervious to being damaged by hole-boring insects and worms.

Q9. Do I need to cap the pilings after installation?

A9. It is not necessary to use pile caps, but there may be some odor and insect issues associated with stagnant water inside the piling. Some owners have drilled a 1/2" hole in the side of the piling at low water to avoid stagnant water. Pile caps, however, often add to the aesthetic quality of your project. Piling caps should be ordered a half-inch larger than the diameter of the piling.

Q10. Does Pearson provide engineering assistance for project design?

A10. We provide recommendations regarding pile diameter, spacing, attachment methods and general layout provided we know the water and soil conditions of your project. We cannot put a P.E. stamp on your drawings, but we can supply a simple layout and general drawings that could be used for obtaining your permit. Structural suitability is the responsibility of your structural engineer.

Q11. Are PEARSON PILINGS environmentally friendly?

A11. Yes. There is extremely low water vapor transmission, very low moisture absorption and no solubility in water in any of the materials in our pilings. They do not contain potentially harmful chemical coatings than can leach into the surrounding soil or water. Our pilings are inert and unaffected by the environment, and they have no deleterious affect on the environment. We have MSDS data sheets for our pilings, and they are available upon request.

Q12. Will my contractor know how to drive your composite pilings?

A12. Yes. Our pilings are often driven by the same equipment in the same way. In certain circumstances slightly different methods must be used, but we can guide your contractor on the best methods for installation. In most cases, installing our pilings are easier because they are lighter than wood, steel or concrete.

Q13. How long have your pilings been on the market?

A13. Pearson Pilings, LLC was started in 2004. However, Pearson developed a prototype design of its current pilings in the early 90s, and the first units were produced for San Diego's Port Authority as part of a successful test program in a commercial application. These pilings are still in service today, validating the success of this advanced composites technology.
