Secant contiguous piles

In areas of unstable or saturated ground conditions, Citilink can consult and advise on the best shoring and retaining wall solutions.

For work sites close or adjacent to other structures, and where a retaining wall may be required to add strength and protect existing features before excavation of the site, Citilink can install contiguous pile walls. These, as the name suggests, use a series of closely aligned piles to form a retaining wall. The piles for this type of retaining wall may use either bored piles or grout-injected piles depending on site-specific conditions.

If water seepage is of primary concern, Citilink can advise and execute the installation of secant pile walls. These types of retaining walls make use of a series of interlocking grout injected pilesto prevent seepage during and after excavation of the site.
