A retaining wall is a structure designed and constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil. The active pressure increases on the retaining wall proportionally from zero at the upper grade level to a maximum value at the lowest depth of the wall. The total pressure or thrust may be assumed to be acting through the centroid of the triangular distribution pattern, one-third above the base of the wall.
At Alan Davis Revetment Walls and Barge Hire, we design and construct retaining walls that are engineered to last — built to withstand the natural forces of water, soil movement, and time. Retaining walls play a critical role in preventing erosion, stabilising slopes, and protecting waterfront and hillside properties. With over 50 years of hands-on experience, Alan Davis and his team bring unmatched expertise to every project, ensuring each wall is not only functional but structurally sound and visually appealing.
Retaining wall design is both an art and a science. Every wall must resist the lateral pressure of soil and water while supporting changes in ground elevation. At Alan Davis Revetment Walls, we take a comprehensive approach, assessing soil type, drainage, and load requirements before construction begins. This ensures that each wall we build performs exactly as intended, even under extreme conditions like flooding or heavy rainfall.
From residential boundary walls to large-scale commercial retaining structures, our team has successfully completed hundreds of challenging projects across South East Queensland and Northern New South Wales. Using high-quality materials including concrete block, crib, and engineered masonry, we construct walls that combine durability with precision. Whether repairing storm-damaged structures or building new waterfront retaining systems from the ground up, we deliver results that stand the test of time.
Following heavy rainfall, a major retaining wall collapse occurred at the Brickworks on the Gold Coast, causing extensive structural instability. Due to our proven expertise in retaining wall construction and remediation, we were engaged immediately to deliver a durable, engineered solution.
Our retaining wall builders managed the full rebuild from site preparation through to completion, ensuring long-term stability and proper drainage. The completed project restored safety to the site and provided a stronger, more resilient structure designed to withstand future weather events.
This project involved replacing a deteriorating timber sleeper retaining wall that had begun to rot, placing nearby palm trees and structures at risk. Our engineers recommended a modern block wall system for improved longevity and strength. The new wall was designed for proper drainage and long-term stability, then rendered and painted to blend seamlessly with the surrounding landscape.
The completed structure not only prevents future soil movement but also enhances the property’s visual appeal and safety for years to come.
Severe flooding in Toowoomba caused a major retaining wall failure, leaving surrounding homes at serious risk of collapse. With limited access and unstable ground conditions, this reconstruction required a carefully engineered crib wall system to stabilise the area.
Our retaining wall experts worked meticulously to reinforce the site, manage water runoff, and prevent further slips. The completed retaining wall restored slope stability, improved drainage performance, and provided a safe, long-lasting solution suitable for high-risk, flood-affected environments.
After significant rainfall, a boundary fence and adjoining retaining wall between two neighbouring properties failed, creating immediate safety concerns. Our team was engaged to remove the damaged sections and design a new, stronger retaining wall system.
Using quality engineered materials and improved drainage solutions, we constructed a wall that stabilised the shared boundary and prevented future soil movement. The completed project not only restored property safety but also improved the overall appearance and durability of the boundary structure.
This project involved a severe retaining wall failure caused by groundwater seepage near a house and swimming pool. The site required careful management due to its close proximity to existing structures.
We replaced the failed wall with a durable crib system designed to handle both lateral soil pressure and water flow. The new retaining wall effectively controls seepage, reduces erosion risk, and provides long-term stability for the surrounding property. The result is a secure and well-drained structure built to last.
A deteriorating timber sleeper wall near a swimming pool had begun to rot, creating instability and potential safety hazards. Our team removed the decayed sleepers and replaced them with a modern, reinforced retaining wall system designed to withstand constant exposure to moisture.
New wall features improved drainage, durable materials, and a clean, contemporary finish that complements the pool area. The completed project ensures long-term soil support, enhanced safety, and an improved outdoor environment for the property owners.
This retaining wall reconstruction was carried out between two neighbouring homes following a serious wall collapse that caused ground instability.
Due to the risk of further slips, we implemented a staged construction method to stabilise the area progressively. The new engineered wall was built using high-quality materials to ensure maximum structural integrity. Our approach provided continuous ground support throughout the project, restoring stability and preventing future movement while ensuring both properties remained protected and secure.
This project involved replacing a failed timber retaining wall and decking structure that had deteriorated from long-term water exposure. With limited land access, our barge was used to transport equipment and materials directly to the site.
All damaged timber was removed and replaced with a reinforced wall system designed for strength, durability, and resistance to future decay. The completed works not only restored stability along the waterfront but also enhanced the visual appeal and usability of the area.
Following periods of intense rain, a besser block retaining wall collapsed due to poor drainage and structural weakness. Our team carried out a full demolition and rebuild using a reinforced block wall system with upgraded footings and engineered drainage design.
The newly built structure provides improved water management and superior load-bearing capacity, preventing future failure. This project demonstrates the importance of proper wall design and drainage in ensuring long-term stability and protecting property against water-related damage.
An original developer-built retaining wall had begun fretting and showing signs of structural failure, with minimal clearance between buildings creating a challenging work environment.
Our retaining wall construction team safely dismantled the deteriorating wall and replaced it with a high-strength retaining system designed for confined access areas. The new wall offers enhanced lateral stability and improved drainage, effectively preventing future fretting or cracking. The completed project restored safety, functionality, and confidence in the structure’s long-term performance.
This retaining wall project required a complete rebuild after timber sleepers failed between two closely positioned properties. Given the limited space, careful planning and precision engineering were essential to avoid further damage.
We designed and constructed a certified masonry retaining wall to provide maximum strength and durability. The completed structure meets all engineering standards, ensures the stability of both properties, and eliminates the risk of future collapse. The finished result is a safe, long-lasting, and visually clean wall system.
When it comes to retaining wall construction and repair, experience and engineering expertise make all the difference. At Alan Davis Revetment Walls & Barge Hire, we take pride in designing and building walls that provide lasting stability, enhance property safety, and improve overall appearance.
