What You Need to Know About Rock Excavation

Rock excavation is defined as the excavation or hard, compacted or cemented materials that often require blasting or the use of ripping and excavating equipment larger than that defined for common excavation. In addition, excavation and removal of isolated boulders or rock fragments larger than 1 cubic yard is also classified as rock excavation.

If you are in need of such services, there are two methods of execution. First is the mechanical method where rock is cut away at the bottom to form level bearing that follows natural strata. This can also include removal of boulders and fragments that may roll into excavated areas or careful removal of final layers to provide a base for footings and foundations. The second method is the explosive method where rocks are excavated by blasting in accordance with requirements of approved proposal. This would result to disintegration of rocks which are then removed. To determine the best method to be used, better get in touch with a reputable company that is knowledgeable on excavating procedures.

Rock excavation can be a risky procedure and there are a few safety protocols to follow as to avoid any untoward incidents.

  1. Excavations in public places should be fenced off to prevent pedestrians and vehicles falling into them.
  2. Precaution should be taken such as backfilling or securely covering excavations if there is chance that children might get onto a site out of hours.
  3. Excavations in public roads or streets should be backfilled or covered over at night to minimise the risk of accidents to the public.
  4. Materials should not be left lying beside the area of work if not required for imminent use beside the excavation.
  5. In rock cut excavations where the rock is friable, netting should be used.
  6. Whenever working or visiting an excavation site, always wear a hard hat.

In any project, safety should be given utmost priority. A safe system of work should be in place all the time to protect workers as well as the public from potential hazards.
