Retaining Walls in Murwillumbah

The most common causes of retaining wall failure are poor drainage, inadequate footings and insufficient wall thickness for the height required. Water pressure building up behind the wall is the biggest culprit. A properly built wall will include compacted footings, correct batter or reinforcement for the height, and adequate drainage to prevent hydrostatic pressure from developing behind the structure.

Both have their advantages depending on the application. Natural rock offers a more organic aesthetic, is extremely durable and blends well with rural and hinterland landscapes. Concrete blocks like Besser or link blocks provide a cleaner, more uniform finish and are well suited to taller or more engineered retaining applications. The best choice comes down to site conditions, wall height, budget and the look you're after.

Yes, retaining walls are commonly built on steep slopes and are often the primary reason one is needed in the first place. The steeper the slope and the taller the wall required, the more important it is that the design and construction account for soil pressure, drainage and footing depth. For very steep sites, a multi-level or stepped wall approach is often the most practical and structurally sound solution.

Retaining wall costs vary considerably depending on the size, height, materials chosen, site access and the complexity of the job. Natural rock walls generally cost more than sleeper walls but last significantly longer. The only reliable way to get an accurate figure is to have a contractor assess the site and provide a detailed quote based on the actual scope of work required.
