Retaining wall leaning or bulging — Rotterdam, Zuid-Holland
A leaning or bulging retaining wall is a structural failure that gets worse with every rain. Water pressure (hydrostatic pressure) builds behind the wall when the drainage system clogs or was never installed, and the weight of saturated soil pushes the wall forward. Other causes include inadequate footing depth, missing or degraded tiebacks/geogrids, frost heave, and tree root pressure. A wall leaning more than 1–2 inches out of plumb is at risk of sudden collapse — especially dangerous on slopes near homes, driveways, or walkways. A landscaper experienced in hardscaping can assess the wall, install or repair French drains behind it, rebuild collapsed sections with proper gravel backfill and drainage fabric, and add deadman anchors or geogrids for long-term stability.

Compacte tuinen, de natte bodem en het zeeklimaat bepalen het hovenierswerk in Rotterdam: drainage en verhoogde borders tellen, terwijl de buitenwijken gestaag tuinonderhoud en de omslag naar onderhoudsarme beplanting vragen.
