A retaining wall can create more usable space in your yard, giving you room to plant a garden, create an entertainment area or do any number of other tasks.
An engineer trained in structural and geotechnical design will customize a retaining wall solution based on your soils at site, with many types of retaining walls available to choose from.block pavers
Gravity Retaining Walls
Gravity alone provides resistance against lateral pressure; mass walls typically consist of bricks, pavers, mortarless stone or concrete blocks but can also be made from dry-stacked rocks.
These walls can be built either on-site or precast and are an economical choice for walls up to 3 m in height.
These walls typically include an attractive protective covering to enhance their appearance, are simpler and cheaper to build than solid gravity walls and require less concrete, thus cutting costs significantly. They’re an excellent solution where there is limited room for wide barriers. Plus they make pipelaying simpler as they can accommodate curves and corners more readily than gravity walls do!
Cantilever Retaining Walls
Cantilever walls are designed to hold back soil between two elevations. However, unlike gravity walls they are exposed to lateral pressures which may increase digging depth significantly and therefore require careful design for maximum effectiveness.
Cantilever walls are constructed using materials like precast concrete elements and wood blocks. Other varieties of cantilever wall design may incorporate crib walls composed of interlocking wooden or concrete blocks and gabion walls made up of wire baskets filled with rocks.
Pile retaining walls are typically composed of piles driven into foundation soils individually and can reach 6 meters in height. Topped with unique fills to reduce lateral pressure and improve stability of the structure, they may also feature drainage systems behind their piles to help decrease hydrostatic pressure behind and thus increase their blueprint value.
Buttressed Retaining Walls
Buttress walls are typically constructed out of steel-reinforced concrete or mortared masonry and use leverage to resist lateral pressures. They have right-angle wingwalls near their bases which transfer pressure directly from the wall onto the soil underneath it – though these may be less expensive than cantilever walls.
Piled walls use piles driven into the ground as strength sources, making them among the most cost-effective and popular forms of retaining walls. Piled walls can withstand high lateral loads without disturbing surrounding structures or properties and offer many advantages but require significant engineering work for proper functioning.
Reinforced Retaining Walls
Retaining walls are used to prevent erosion and create usable space on sloped land. Constructed using heavy materials like concrete block, stone or masonry they are commonly found in both residential and commercial landscaping projects.
Reinforced retaining walls are an innovative type of wall construction which relies on reinforcement to support soil mass and resist gravity-induced pressure, without the need for costly excavation work. They can be built at extremely deep digging depths without incurring additional expenses for excavation work.
Behavior of these walls was examined using a displacement-based model, with final horizontal displacements close to and at the collision surface being negative; additionally, their separation ratio increased as their height did.
Sheet Pile Retaining Walls
Sheet pile walls consist of interlocked steel piles connected by thread. Used in permanent structures to control soil movement near foundations and as shoring in excavation works, sheet pile walls also play an integral role in cofferdams and seawalls.
Vinyl sheet piling is a new material used in marine environments for marine retaining walls, seawalls and bulkheads. Crafted from modified polyvinyl chloride, it offers non-corrosive protection in most marine environments.
Installation can be accomplished using silent and vibration-free methods and provides an effective water seal at its junction point. Available in various lengths, dimensions, and steel variations for easy customization, these piping connectors can also be increased in length by welding or bolting and benefit from corrosion protection measures like coating or cathodic protection for an enduring solution.
Anchored Retaining Walls
Anchored retaining walls use cables and anchors buried deep underground to support their structure, providing more support for lighter or thinner walls that may otherwise collapse from pressure from above or from below. This makes them resistant to lateral pressures while simultaneously offering increased stability for these types of walls.
This option for slope protection can help to reduce erosion, making your property safer and easier to manage while also being cheaper than other solutions.
When selecting the appropriate type of retaining wall for your project, several considerations should be taken into account, including material choices, environmental impacts, durability comparison and aesthetic appeal. It is ultimately important to find one which best meets both project needs and budget constraints.
