The retaining walls on this Mosman property were a mix of failing rotten timber and unstable garden edges, with drainage issues adding pressure behind the structures. The site needed a more permanent retaining solution and a cleaner garden layout.

We removed the old timber wall, installed new timber retaining where it suited the site, built a rendered besser block retaining wall for the heavier retained section, and corrected the drainage behind the walls and beds. The garden now holds properly, drains properly, and presents as a finished upgrade rather than a patch repair.

Case Study Details

The site issue, the work completed, and the outcome visible in the project photos

The site issue

The garden had failing timber retaining walls, unstable edges, and drainage problems that were adding pressure behind the retained areas.

Site constraints

Different retained sections needed different wall treatments Drainage had to be corrected behind walls and garden beds The final layout needed to look like a finished garden upgrade, not a patch repair

Work completed

Scope: Remove failing timber retaining sections, Install new timber retaining where suitable, Build rendered besser block retaining for heavier retained areas, Correct drainage behind walls and beds, Re-form garden beds and clean the site. Sequence: Remove rotten and unstable retaining sections Choose timber or rendered besser block based on the retained load Install drainage behind the new retaining work Rebuild the garden beds and finish the retained areas cleanly

Outcome and aftercare

The garden now has stronger retaining, corrected drainage, cleaner beds, and a more permanent finish across the upgraded sections. The drainage paths and retained soil should be checked after heavy rain, and beds should be maintained so water does not build up behind the walls.
