Earth retaining walls for secure footing in the terrain
In many gardens, builders are faced with the challenge of accommodating varying heights in the terrain or at the patio in a visually appealing way. This can be accomplished by ground modeling alone, but often walls are also needed to bridge terrain jumps. Compared to solid concrete or stone walls, earth retaining walls made of metal give the garden a modern character. They require considerably less installation space and can be easily screwed and anchored in the ground on site. Due to the lower weight, heavy equipment can be dispensed with in many cases during installation. This saves money and prevents unnecessary soil compaction in the rest of the garden.
We present a particularly stable solution with our TERRA PALA earth retaining wall system. The high-quality metal elements made of Corten steel, stainless steel or hot-dip galvanized steel are designed to compensate for height differences of up to 100 cm while absorbing the slope forces.
Basically, we distinguish between the following types:
- Type L profile “CLASSICAL”: with sharp end edge and high material thickness
- Type C profile “MASSIVE”: round edge and lower material thickness
- Type C profile “LIGHT”: especially for the roof garden with lower dead weight
- Type I profile: simple, cheap, but more installation effort
Depending on the design, soil mechanics, load and installation situation, we recommend the use of masonry units or L-bricks for higher earth retaining walls above 60 cm, which are then clad with Corten steel or stainless steel. We offer wall facing under the name MAURESTA.

Technical structure of TERRA PALA earth retaining walls
Earth retaining walls must be planned during the design of the garden. For fastening, they are securely fixed in the anti-freeze gravel by means of flat anchors or in the concrete foundation by means of dowels. To avoid waterlogging behind the wall, we advise to install a bubble wrap or fleece on the back. A drainage pipe that provides good drainage is also helpful. Finally, capillary-breaking fill material such as moraine gravel should be backfilled before the earth retaining wall is backfilled with soil.

Overview
Earth retaining wall types - different structure
The earth retaining wall is designed to be strong enough so that the structure can absorb the applied slope and embankment forces. Depending on the installation situation, material thicknesses from 3 mm to over 12 mm are necessary. Basically, the constructions can be divided into the following types. For all types there are also matching corners and rounding elements.
Earth retaining wall type C profile "LIGHT
Specially designed for the roof garden with lower dead weight and reduced bearing loads. The basic construction is made with lightweight aluminum 3 mm. After assembly is completed, the construction is laminated with seamless pluggable cladding sheets to create a visually solid wall. Screws are not visible from the front. Important: This type has no support function, so it is not suitable for off-road use and only for light substrates.
Stability and proof
In principle, the following applies to all objects – also in the garden: The installing company must guarantee the stability and, if required, also prove it. A verifiable structural analysis must be prepared for each individual case and generates corresponding expense. When preparing your quotation, make sure that you always quote in such a way that – if a verifiable structural analysis is required – the costs for this can also be invoiced separately.
Alternative systems
Often, as a cost-effective alternative to the massive earth retaining walls from heights of 60 cm, the use of L-angle bricks and masonry units. The assembled concrete elements (L-bricks, angle bricks, wall panels, etc.) are then finally faced with the MAURESTA wall facing system at low cost using Corten steel or stainless steel sheets so that the impression of a solid metal wall is created. In addition to the cost advantage, the concrete elements are usually available from stock and simplify the logistics on the construction site considerably.
When intercepting different heights, we offer four fundamentally different systems. Depending on the situation, one of the systems will best get you there. If you have any questions, please feel free to contact us.
