Code: SIS-BW-SP

Description

SIS is head quartered in Australia, a continent surrounded by ocean meaning that so many of the projects undertaken by us require skill and expertise when designing and installing boardwalk structures in water. SIS’s foundation is built on the design, construction and installation of superior sustainable materials. These materials second only to their environmental credentials will outlast and outperform the majority of alternative constrution materials. This therefore means that our composite materials are perfect for harsh marine environments. This then leaves the challenge of installation.

In general, three types of foundations are used to support marine structures: gravity-based, monopile and jacket or template structures. Driven piles continue to be the first choice for both ourselves and our clients and dominate the American and European marine structure market, particularly steel pipes driven open-ended into the seafloor. Pile sizes for standard pedestrian structures, ranging from 125mm to 250mm in diameter, are driven routinely for SIS structures to depths of 20 meters or greater in a variety of geotechnical settings.

However, there are many situations where piles cannot be driven to full penetration without drilling-and-driving techniques. Pile-driving difficulties can occur due to the piles being dented or otherwise damaged during handling, hammers performing poorly, soil conditions leading to harder driving than expected, or encountering rock layers or boulders. If stiff clays are encountered during installation, bored piles are preferred.
