R+F Ecowall®

System description

R+F Ecowall allows the construction of retaining structures with slopes of up to 85° without the use of

concrete. The front facing consists of layered, dry stonework, whose appearance can be adapted to

individual architectural needs. This dry stonework is stabilised by a specially galvanized steel mesh, and

the backfill soil behind the facing is reinforced with TenCate geosynthetics. The result is a very stable,

steep retaining structure with high load-bearing capacity.

Facing System

R+F Ecowall is a facing system for steep slopes and soil-retaining structures reinforced by geosynthetics. The

system is primarily used for stabilising stone- or gravel-filled front surfaces with a maximum slope of 85°, but

may also be used in combination with vegetated surfaces up to an angle of 70°.

R+F Ecowall requires no maintenance. Furthermore, the stone layering also provides shelter for insects and

other small fauna.. And the additional use of climbing and hanging plants opens up a large variety of different

design options.

R+F Ecowall utilises steel-mesh grids which are joined together to form an angled interlocking facing unit.

Loads are transferred to the geosynthetic reinforcement products TenCate Polyfelt Rock PEC or TenCate

Miragrid GX by friction between these and the steel mesh. Layers of stone or gravel-fill material are applied

directly behind the front mesh. The whole system is then backfilled with soil of adequate bearing capacity.

System components

1. Facing System

R+F Ecowall system consists of soil and a welded

steel wire front mesh. The mesh is produced with

eyelets on one side and connected on-site with push-

through rods. The great advantage of this well-

proven connection system is its easy handling. The

desired slope angle is achieved by means of

anchoring hooks.

If an extremely thin layer of gravel facing is desired,

an additional inside mesh may be installed at a

distance of approx. 200 - 300 mm from the front

mesh. This helps to minimise the amount of gravel

needed.

Anti-corrosive protection consists of an aluminium-

zinc alloy (GALFAN). This ensures 3 to 5 times longer

service life than in conventional galvanized coatings

of comparable thickness. It may even be used along

roads with de-icer application.

The wire thickness of the front mesh (6 mm)

guarantees high torsional stability. The mesh opening

size is 125 x 125 mm. For gravel with 40 - 125 mm

grain size an additional fine inside mesh may be

installed.

2. Geosynthetic reinforcement

TenCate Polyfelt or TenCate Miragrid

3. Backfill material

TenCate high-strength geosynthetics stabilise and

reinforce the backfill soil. The properties and

behaviour of the resulting composite material mean

that the structure can accomodate unusually high

loads.

TenCate Miragrid GX is a high-tensile geogrid made

of polyester fibres with a polymeric protective

coating. The open structure and high flexibility of the

fibres ensures an excellent interlock with coarse

soils, thus providing high load transmission.

TenCate Polyfelt Rock PEC is a high-tensile

compound made of polyester yarns and a nonwoven

geotextile. Due to its in-plane flow capacity it can be

used together with cohesive soil infill materials.

n most cases the on-site soil can be used, provided

it is compactable and has adequate frictional

properties. Frost-resistant fill material is required at

the front of the structure to a depth appropriate to

the local climate .

Installation

R+F Ecowall does not require a foundation. All it takes is a levelled, compacted and stable/load-bearing

subgrade. The geosynthetic reinforcement products are installed with the required anchor length. The facing

system is positioned and fixed with steel hooks. Then the first layer of backfill is applied. Room is left at for the

dry-stone facing immediately behind the shuttering, and the stones placed after backfill compaction.
