Flooding is an inevitable natural event. Although good design can go some way to improving the stability and durability of roads and dams, there is frequently a substantial amount of deterioration after flood events that can be rectified and managed with the usage of geosynthetics.
Instantly after the flood: how to organize remediation works safely and effectively
Good geosynthetic engineering is pivotal to mitigating insignificant flood damage, but sometimes major floods can wreak severe environmental destruction on roads and pavements, almost demolishing them.
The cleanup, rehabilitation, and new structure of geosynthetics need to be approached carefully, particularly if work is starting soon after the flood event. Destabilized ground and dams, and drenched ground can make for difficult working situations that require extra strength and stabilization whilst work is being undertaken.
Heavy rainfall and eventual surge runoff from the higher ground can result in surface deterioration, soft and dangerous soils, and percolation of water through the ground. Detailed inspection of the ground situation requires to be created by an engineer, as well as reporting on any new deterioration, landslides or depleted areas in the outskirts of the area to be rebuilt.
Usually, the work zone itself requires to be strengthened and reinforced with a geogrid to improve the stability of the base course, enabling heavy earthmoving and lifting tools to safely access the area.
Geogrids can be an extraordinary solution for stabilizing working platforms and access roads, permitting crucial repair works to be carried out. And when it comes to slants and embankments, geocells can furnish ongoing strength and support to the soil, particularly when revegetated.
Revamping for the future: Geosynthetics for flood mitigation
To mitigate the harm induced by future floods, engineers are required to lessen the interaction between water and soil. This can be accomplished by reducing the scouring effect of water on structures, or by increasing the stability and resistance of the ground itself.
Bolstering the ground can be attained with the assistance of geosynthetics such as geogrids, rock mattresses, or heavy-duty deterioration control matting. Installing a geosynthetic product can usually deliver a long-term solution, and if the relevant environmental factors have been taken into account, it can also help rehabilitate future flood damage.
Turf reinforcement mats (TRMs) and strengthened deterioration control matting can furnish strength to slopes and gradients, preventing landslides and decreasing the damage caused by flood events.

Geosynthetics have delivered a vast range of flood protection solutions around the world.
They are utilized for the deterioration of coastlines and riverbanks. They permit dunes and prevent sand washout in the complexion of storms. They provide choices for sandbags. For many assignments, they deliver crucial levee reinforcement to deliver long-term defense against flood dangers.
Here, we summarize and link to some of Geosynthetica’s outstanding tales regarding geosynthetic strategies in flood defense.
Flood Protection with High-Strength Reinforcement
The summer of 1997 flooding along the Oder River was a portion of what was called the Millennium Flood. It was the largest known flood along this main waterway border between Germany and Poland. The circumstance stayed several weeks. On the German side, multiple dams broke and around 5,500ha of farming land and territories with around 400 residential buildings were flooded. Several thousand people were vacated.
This disaster and subsequent vulnerable floods damaged the dam system in numerous locations. Weak points in the dam geometry and subsoil problems were determined as causes of many of the breaks.
Know the Geosynthetic Advantages
Geosynthetics which includes geotextiles, geomembranes, geonets, geogrids, geocomposites, and geosynthetic
clay liners, usually utilized in a variety of traditional materials, offer the following benefits over traditional materials:
- Space Savings - Sheet-like, geosynthetics take up much smaller room in a landfill than do comparable to soil and aggregate coatings.
- Material Quality Control - Soil and aggregate are normally heterogeneous materials that may differ significantly across a site or borrow area. Geosynthetics on the other hand are fairly homogeneous because they are contrived under tightly controlled conditions in a factory. They undergo stringent quality control to minimize material variation.
- Construction Quality Control - Geosynthetics are manufactured and usually factory “prefabricated” into big sheets. This lessens the required number of field connections or seams. Both factory and field seams are made and experimented with by trained mechanics. Contrarily, soil and aggregate coatings are created in place and are subject to variations induced by weather, handling, and placement.
- Cost Savings - Geosynthetic materials are normally less expensive to purchase, transport, and install than soils and aggregates
- Technical Superiority - Geosynthetics have been planned for optimal performance in the desired application.
- Construction Timing - Geosynthetics can be installed fast, delivering the flexibility to build during short construction seasons, breaks in inclement climates, or without the need to demobilize and remobilize the earthwork contractor.
- Material Deployment - Coatings of geosynthetics are deployed consecutively, but with a minimum tagger between coatings, permitting a single crew to efficiently deploy multiple geosynthetic layers.
- Material Availability - Various suppliers of most geosynthetics and ease of shipping assure competitive pricing and prepared availability of materials.
- Environmental Sensitivity – Geosynthetic systems lessen the usage of natural resources and the environmental deterioration associated with quarrying, trucking, and other material handling activities.
