Retaining Structures

Retaining wall repair and construction stops complete devastation.

Retaining wall failures are common, usually subtle, manifesting as bulging or cracking in walls. Other times they can be more catastrophic, resulting in complete collapse – potentially causing significant harm to people and property.

We assess the condition of the existing wall, suggesting strengthening measures to ensure a structure will be stable in the long term, focusing on longevity not a quick-fix.

CAN has an array of potential solutions for retaining walls, whether you are looking to build a new one, strengthen an existing one or remediate a failing wall. Walls can sometimes require urgent, temporary support while a permanent solution is devised. From temporary wall props, anchors and bulk, gravity retaining solutions, we’ve got you covered.

Permanent solutions for retaining structures, both old and new, include:

  • gabion baskets
  • reinforced earth
  • ground anchors
  • pre- cast concrete units
  • cast in-situ concrete
  • sprayed concrete
  • timber or concrete crib or masonry.

By combining methods we can provide not only engineering certainty, but aesthetically pleasing solution to retaining wall strengthening.

Is water the cause?  Careful groundwater management is critical. As a result, we often employ the use of weepholes and bored inclined drains in conjunction with our

Inspection, Design & Build

We assess the condition and performance of retaining structures, designing and delivering solutions that restore strength and extend service life.

Anchors

We install and test anchor systems to enhance the stability of retaining walls and structures. Designed for durability and performance, our solutions help resist movement and manage ground pressures effectively.

Gabions & Retaining Structures

We construct and repair gabion baskets and retaining systems that provide robust, flexible support. They offer both structural integrity and effective drainage.

Void Filling & Grouting

We restore integrity to retaining structures by filling voids and strengthening underlying ground conditions.

Devegetation

We remove invasive or damaging vegetation from retaining structures to prevent root intrusion and structural weakening.
