Retaining structures  and reinforced soil systems vary in type, methodology and materials used. Concrete, timber, recycled plastics, geogrids and metal are all used for various systems. The construction methodology also varies from system to system. It is important to use a solution that offers the best whole life costs, which depends on buildability, ongoing maintenance and design life, among other things.

Whether you're constructing buildings, road, rail or recreational areas, you are likely to need retaining structures to hold back earth. This may be to stabilise a slope, prevent erosion or maximise the available space.

Used alone or in combination, Phi Group's range of techniques offers engineers faced with varied and difficult soils and terrains the best solution to meet their particular challenges.
