The below project was based near Torre Station, Torquay, a Great Western Railway-managed and Grade II-listed station. We were initially contacted to look at the suitability of utilising our asset BaFix & Sleeve-It system, a proprietary system designed to stabilise railway tracks, for a 200m run of track along the edge of a retaining wall to a small stream. The driver for this work was that ballast was falling into the stream, restricting flow and increasing the risk of flooding. Clearing of the stream was also becoming a regular occurrence, which took considerable time and resources to undertake. 220m of asset BaFix 70 and 147 Sleeve-It units, along with handrails, were installed along the edge of the track, increasing track resilience. Once the installation was complete, the ballast was replaced, and cable troughs were reinstated. The associated handrailing was an additional feature of the project, establishing an essential position of safety. The project not only provided an environmental benefit by mitigating the flood risk, but also had a significant social impact. By preventing the loss of ballast into the stream, the project ensured that the train operating companies, commuters, and tourists using the line into Devon and beyond were not negatively affected. This, in turn, contributed to the local economy by maintaining the smooth operation of businesses in the area, thereby reinforcing the project's value and importance.

High performance and recyclable geosynthetic to build better roads and platforms (Subgrade stabilization and soil bearing capacity improvement)   Reducing environmental impact and saving cost become more and more the main objective for all construction projects. Granular platforms are the basis of many infrastructure’s foundations, with the objectives of carrying the loads and controlling the deformation. In a Lidl parking project, a clear saving of granular material obtained by using a multifunctional and high stiffness geosynthetic.   The results of the measurements on the bearing capacity, with and without reinforcement, demonstrated a high benefit with using a specific geosynthetic which led to a high saving in the amount of the required granular material.   It significantly reduced both naturel resources consumption and the number of transportation trips, mitigating the project's environmental impact and reducing community disturbance. The extension of the project's sustainability aspect once the project is complete, is also made possible by using a recyclable geotextile. This kind of project is a model for circular economy practices.   Start following the EAGM on LinkedIn for weekly updates on the advantages of the use of geosynthetics.

Green Face Vegetated Reinforced Soil System In 2023 Maccaferri Construction completed the Design, Supply and Installation of over 1100m2 of Green Terramesh® for multiple slopes for a prestigious development site in Bothwell. Using a combination of selected site won fill and lime modified site won fill, circa 4000m3 we were able to help significantly reduce both the volumes of unsuitable materials needing to be removed from site and the volumes of quarried material needed to be imported. This development also included the Design, Supply and Installation of 250 lin m of gabion walling and over 500m2 of MacWall.  The MacWall® segmental blockwork retaining wall system combines the aesthetics of masonry walls with the engineered reassurance of reinforced earth. Segmental block retaining walls (SRWs) are increasingly popular due to their ease of construction, cost-effectiveness and versatility. The two components of the MacWall® system are: 🧱 split-face concrete modular block in a range of colours to suit adjacent structures and environments. 🧱 Reinforcement Paragrid® geogrids sandwiched between the courses of block. Paragrid® geogrids are placed horizontally within the structural backfill to the wall, providing tensile strength and reinforcing the soil mass. The grids also tie the fascia blocks to the reinforced soil. Maccaferri Gabion is a Double-Twisted “DT” wire mesh are filled with stone at the project site to form flexible, permeable, monolithic structures such as mass gravity walls, channel linings, revetments, and weirs for geotechnical, hydraulic and erosion control projects. They have a HAPPAS BBA certificate and have a design life of 120 years even in highly aggressive environments. Green Terramesh® is an environmentally friendly modular system used to form vegetated (green) faced soil-reinforced slopes (RSS) and embankments. It has been used globally on some of the most significant infrastructure schemes. It consists of pre-fabricated units of double twisted wire mesh (8×10 type) lined with an erosion control blanket and stiffened with a welded mesh panel. Two pre-formed steel braces are supplied to be connected at the job site to maintain the unit to the required slope angle. The angled front face and the erosion control blanket are designed to facilitate the establishment of natural vegetation in the units; an important requirement of Green Terramesh®.

Cement, Concrete, Clinker: Decoding the Building Blocks 🧱 Ever wondered about the difference between cement, concrete, and clinker? Our cement specialist, Marta Díez García, explains it in simple terms:   💡 Clinker: Think of clinker as the "building block." It's produced by heating a combination of limestone, chalk, quartz sand, bauxite, iron ore and clay at very high temperatures in a kiln. Clinker forms the backbone of many construction materials.   💡 Cement: Cement acts as the "glue" that binds aggregates together in the presence of water, forming a solid material. It’s produced by finely grinding clinker blended with a few additional components.   💡 Concrete: Concrete is the final product. It’s made by mixing cement with sand, gravel, and water, creating the strong, durable material used for roads, bridges, buildings…etc   In short: Clinker is the base, cement is the binder, and concrete is the finished product! Did you know the difference between clinker, cement and concrete?

In a recent lab testing program, D-Carb, with 15% lower CO2 emission, has demonstrated a highly satisfactory performance for the precast industry, particularly in terms of workability, strength and whiteness, supporting a smooth transition towards more sustainable products. As highlighted by Guillermo Hernandez Carrillo, the fresh state of self-compacting concrete showed that with slight 0.05% increase in superplasticizer, the results exhibited improved stability especially in workability. Furthermore, D-Carb matched the performance of Aalborg White CEM I 52.5R at both 7 and 28 days, achieving the 20MPa strength target at one day. Most importantly, the transition to D-Carb does not compromise the whiteness, maintaining a similar level to CEMI 52.5R while supporting a more sustainable approach.   Read more in the article on White-Hub: https://lnkd.in/gWhe9ADw #Cementir #WhiteHub #DCarb #CO2emission #lowcarboncement #whitecement #precastconcrete #selfcompactingconcrete #decarbonization #innovation #lowcarbonconcrete #greenbuilding

The constraint effects due to shrinkage are usually approached by simplified rules of experience or formulas on standards, which provide a minimum reinforcement to control the cracking. These approaches are not adequate nor optimal when facing complex geometries, which are also affected by other loads, such as high water pressure. This motivated Raul Rodriguez, COWI, to approach the problem of the constraint effects by using area models in SOFiSTiK with a non-linear material. https://lnkd.in/d4nJ9YGr
