Question 11

Accepted Answer

Yes. We encourage contractors to utilize predictive inventory strategies during the fourth quarter to avoid holiday supply surges and year-end price fluctuations. We can work with you to secure and stockpile materials in advance of your project deadlines.

Question 12

How long does Rip Rap last?

Accepted Answer

Because we use highly durable, weather-resistant stones (primarily limestone or granite), our rip rap is designed to provide a lifetime of protection. Its longevity depends on the intensity of wave action and proper initial installation.

Question 13

Is rip rap better than a traditional seawall?

Accepted Answer

In many Florida environments, rip rap is preferred over vertical seawalls because it absorbs wave energy rather than reflecting it. This reduces "scour" (erosion at the base) and provides a more natural habitat for local aquatic life.
