Retaining Walls

Burras Ltd offers an extensive range of retaining wall solutions. This means that we can offer not only the most cost effective solution but also the most robust. Four of the main types of retaining walls Burras Ltd offers are:

Secant Wall

A secant wall is typically constructed using interlocking CFA piles to form a semi waterproof retaining wall. It is our most common form of retaining wall used when constructing a basement. It can also be used on sloping sites to form a retaining wall that can easily be clad in brick or timber.

Contiguous Wall

A contiguous piles wall is also typically constructed with CFA piles but also can be formed using auger bored piles when no water is present in the ground. It offers a cheaper alternative to a secant wall but doesn’t form a watertight structure.

Sheet Piled Wall

Sheet piled walls can be used as permanent or temporary retaining wall systems. Burras Ltd have extensive experience installing sheet piled walls through a range of techniques from vibrating them in with a vibro mounted to an excavator or crawler crane to installing them with a silent piler. Sheet piled walls are a perfect choice for marine projects.

King Post Wall

King post walls can be extremely quick to install. Where retained heights are under 3m, it can be a cheaper alternative to secant, contiguous and sheet piled retaining walls. Typically they are formed using UC columns and placing either timber sleepers or concrete planks between the posts. The posts can either be vibrated into the ground of placed in pre-bored holes.
