Our Solutions

Embankments, Slopes, Bunds and Walls

What if contractors could construct embankments, slopes, bunds and walls during the construction phase by using more aesthetically-pleasing solutions and increase site usability?

Embankments, slopes, bunds and walls

Slopes and structures on projects commonly follow a shallow angle and are conventionally constructed from reinforced concrete. However, our aesthetically pleasing innovations ensure a reinforced steepened slope can increase the usable area on site, thereby increasing the value of the land available.

Plus, a reinforced soil slope, rather than concrete, is much more aesthetically pleasing for residents, particularly with a planted face. As well as being far more aspirational, a reinforced retaining wall will reduce costs and time on a construction programme, often by up to 50 per cent. These savings can be increased further through curved and tiered reinforced soil retaining walls.

Freeing up additional time

Reinforced concrete options for slopes and structures are labour intensive to install and carbon intensive to create. Our E’GRID Uniaxial geogrid solution can be invaluable in overcoming these issues and help to find additional time in the build programme – before the first on-site construction even begins.

As a result of innovation in the geogrid sector, a reinforced steepened slope can be engineered, increasing the usable area on site, thereby boosting the value of the land available.

Soil banks are constructed by wrapping the geogrid around the soil face to the required slope angle; this process is repeated in layers to create a stable/steep embankment.

These solutions offer a more sustainable option to the traditional concrete alternatives, and are also much more competitive on cost and can be constructed far more quickly. They also improve the bearing capacity and safety of a structure.

Further cost savings can be made by re-using on-site material, even from previously failed slopes, which can be excavated and re-used to construct a stable embankment or slope.

ProtectaWeb for robust slope reinforcement

ProtectaWeb is designed to prevent shear failure and lateral movement of aggregate materials. It provides contractors with a straightforward installation method, even on steep banks and slopes, providing resistance to erosion from wind and water run-off.

As a perforated panelled system, water is allowed to flow freely between cells, encouraging drainage and vegetation growth.

ProtectaWeb is an incredibly cost-effective solution for reinforcement, reduce granular fill requirements by up to 50%, providing carbon reductions in the process. It is lightweight, easy to handle and cut. It can be used in conjunction with many common fill materials, even in locations of high load intensity. When infilled, ProtectaWeb provides a semi-rigid foundation.

Old Colwyn embankment
Success stories

Old Colwyn embankment repairs

We were approached by Alun Griffiths (Contractors) Limited, and Atkins to advise on a suitable geotextile to go beneath rock armour as a heavy duty separation and filtration layer. The geotextile would form part of the necessary repair work to Network Rail Wales’ embankment at Old Colwyn, Conwy.

During the design phase, Atkins considered and appraised options using either 3,000kg or 6,000kg rock armour with an appropriate grade of MultiTrack™ SNW geotextile beneath. The final design solution was then agreed between Atkins, Alun Griffths (Contractors) Ltd and Wrekin Products, utilising 6,000kg rock armour overlying MultiTrack™ SNW140 geotextile.

Chelsea Garden Project

The Hospital of St John and St Elizabeth in London is one of the UK’s largest independent charitable hospitals. This project involved a need to solve the design constraints for the relocation of a Chelsea Flower Show garden to a hospice, on part of the hospital site. Wrekin provided geosynthetics products, and our experts led on-site product installation supervision to devise innovative solutions.
