Colin Ashby, Principal Engineer, has written a paper on the design of timber pole retaining walls and developed a formula for the design of timber pole footing embedding which takes into account the effect of the reduced support available due to the slope of the supporting ground. Traditional design methods do not allow for the supporting ground below the wall to be sloping. Who better to design your timber pole walls than Ashby Consulting Engineering Ltd.

While there are various ‘off the shelf ’ designs for retaining walls, especially for DIY timber pole retaining walls, they may or may not be suitable for your site. Often these designs assume that the ground conditions are ideal whereas, in reality, supporting ground varies enormously and is most often far from ideal.

Whether or not a building consent is required for the construction of a retaining wall, we would advise that all walls are designed by an expert and supervised during construction by a chartered professional engineer experienced in retaining wall design and construction.
