Filling the geogrid with a mixture of gravel and sand

We completed the task: construction of a site for storage of chemical reagents and parking for vehicles.

Excavation was carried out, sand filling with layer-by-layer compaction, use of geotextiles and geogrids with filling of the geogrid with gravel and sand.

Parking and storage area

The plant chief decided to create a storage area for reagents and a parking spot suitable for trucks. The project required the following tasks to be completed:

  1. Excavation of test pits. Test pits were dug to locate underground utilities, including an electrical cable and grounding system. The cable and grounding routes were marked with white tape during backfilling.
  2. Removal of the topsoil layer. The top layer was loose, contaminated soil, containing organic material and a fertile layer. It was removed entirely down to the inorganic layer.
  3. Layered backfilling with sand and compaction. Layers of sand were compacted using a plate compactor. A geotextile material was used as a base layer before backfilling.
  4. Placement and securing of geogrid. A geogrid was installed and filled with gravel and sand. The gravel formed a dense layer, which was further strengthened by locking it in place with sand.
  5. Removal of excess sand: Excess sand was removed from the area using a tractor and manually with brooms.

Completed earthwork.

The project resulted in the creation of a storage area for chemical reagents and a truck parking area. The work included soil excavation, sand backfilling with layered compaction, and the use of geotextile and geogrid, with the geogrid filled with gravel and sand. The parking project was completed using soil stabilization.

Order parking place construction

    The parking area construction faced two significant challenges:

    • Confined space with utility lines. The area was narrow and contained electrical cables and a grounding system. The work was conducted in the late fall at above-freezing temperatures, as ground stabilization measures are more effective under these conditions. If snow had entered the compacted layers, the quality of the work would have been compromised.
    • Existing concrete base. A concrete base was present at the reagent storage area, which collected water from the building’s roof. The project aimed to raise the base level and ensure water filtration.

    For chemical plants, safety equipment is required when we make design and constructing sites and parking lots. When designing, it is necessary to take into account the installation of an isolating membrane under the area where a reagent spill may occur. So, a soil depression is designed under the site, like a container, and a membrane is laid at the bottom.

    At the lowest point, a pipeline is provided through which, in the event of an accident, liquid waste can be pumped out for disposal in an incinerator or in a furnace for burning it. Emergency tanks for chemical waste are also being designed.
