BEGREEN steep slope systems

The construction of embankments, walls and noise barriers requires cost-effective and ecological construction methods and system solutions. The requirements are so complex and the possibilities so multifaceted that it is often difficult for design engineers to find a suitable solution. Our Applications Engineering department can help you here.
Instead of simply supplying specific products, we offer you a system solution that is tailored to your construction task and provide a comprehensive service including consulting, planning, dimensioning and installation as well as support during the construction phase.

BEGREEN 45

BEGREEN 45 is an embankment protection system for inclinations of up to 45°. The system is based on laying layers of soil and geogrids alternately, whereby the geogrid acts as a structural reinforcement element.

Based on the project requirements and the quality of the available soil, a structural analysis is carried out to determine the necessary qualities of the geogrid, its anchor length and the thickness of the layers. The soil quality and load transfer are the most important considerations when deciding whether the structure needs to be installed using the envelope method or not.

BEGREEN 45 without envelope

This version is used where the structural analysis shows that simply laying the geogrid and soil layers alternately is sufficient, with no enveloping of the soil. The front face of the embankment is then covered with an erosion control mat to prevent the soil from trickling out or being washed out.

BEGREEN 45 with envelope

With the envelope method, the geogrid is wrapped around at the front of the embankment to form a defined envelope that encloses the soil layer being reinforced. Temporary formwork is usually used on site to construct the envelope. This ensures that the inclination and the layer spacing of the structure comply with the structural specifications. The front of the embankment is covered with an erosion control mat.

BEGREEN 70

With BEGREEN 70, steep slopes with a front inclination of up to 70° can be constructed. The single component system consists of the reinforcing geogrid, a steel reinforcing mat at the front as permanent formwork with bracing hooks and an erosion control mat.

The primary structural reinforcement is provided by a geogrid, which is made of low-creep polyester (PET) filaments and wraps around the layers of soil using the envelope method. The structural design of the earthwork and of the geogrids used depends on the specific project requirements.

During installation, the geogrids must be folded back at the front of the embankment so that they lie below the subsequent layer of soil and are anchored in the structure. This usually requires the use of formwork. To save time and thus costs, BEGREEN 70 includes permanent formwork. The formwork is braced by bracing hooks. To provide the necessary UV protection for the geogrid and to prevent erosion at the front of the structure, an erosion control mat is installed behind the front reinforcement.

Two versions of BEGREEN 70 are available: one with pre-bent structural steel angles and the other with welded and galvanised steel wire mesh mats.

BEGREEN 70 with pre-bent structural steel angles

The structural steel angles are pre-bent in the factory according to the layer height and front inclination. An erosion control mat is attached to the inside of the structural steel angle for trickle protection. The geogrid is laid flat and then along the inside of the angle. The structural steel angle is also braced with steel bracing hooks. After the soil layer has been laid, the geogrid is folded back over the soil and integrated into the structure.

BEGREEN 70 with welded and galvanised steel wire mesh mats

Based on welded and galvanised steel wire mesh mats of standard dimensions of width 80 cm and length 2 m, the resulting layer heights are dependent on the front inclination. Versions with mesh sizes of 5 x 5 cm, 5 x 10 cm and 10 x 10 cm are available. On site, the mats are used to create permanent formwork. The front slope is secured with galvanised steel bracing hooks. Construction then proceeds as with the version with pre-bent structural steel angles.

BEGREEN EASY

1. erosion control mat | 2. geogrid | 3. filling material

BEGREEN EASY can be used to create steep slopes with a front inclination of up to 70°.

This system comprises a reinforcing geogrid, a bracing steel gabion mat and a hinged base grid as permanent formwork with bracing hooks and an erosion control mat. The system components are pre-assembled in the factory.

The primary, structural reinforcement is provided by a polyester (PET) geogrid that envelops the layers of soil using the envelope method. The design and dimensions of the earthwork and the geogrids used depend on the specific project requirements.

To provide the necessary UV protection for the geogrid and to prevent erosion at the front of the structure, an erosion control mat is pre-installed behind the front reinforcement. The standard dimensions of the front mat are 250 x 80 cm.

BEGREEN WAB

1. plastic honeycomb | 2. backfill material | 3. anchoring hooks | 4. geogrid

BEGREEN WAB can be used to create steep slopes with a front inclination of up to 70°.

This system comprises a reinforcing geogrid and a three-dimensional honeycomb grass grid as permanent formwork that also braces the structure and protects against erosion. The bracing hooks are fixed to an anchoring crossbar on the ground. The system components are pre-assembled in the factory.

This requires the use of formwork. To save time and thus costs, BEGREEN WAB uses a honeycomb grass grid as permanent formwork. The formwork is braced by bracing hooks. Due to its three-dimensional structure, the honeycomb grass grid also provides permanent erosion control for the front slope.

With a slope of 70°, the vertical element height is 55 cm. This system is particularly suitable for securing verges, whereby the verge slope is structurally stabilised and an additional honeycomb can be laid horizontally for added stability of the verge.
