Questions our clients ask most often.
Do you use silica sand?
For health and quality reasons we use approved low-silica abrasives such as garnet rather than free-silica sand wherever specifications and HSE rules require, with appropriate respiratory and containment controls.
Can you blast on-site and in the workshop?
Yes. We provide both workshop blasting for fabricated items and on-site blasting with containment for installed structures and maintenance work.
What certification do you issue?
A formal report with photographs and findings plus a Certificate of Conformity citing the specific clause references. Hard-copy and electronic certificates are available, and records are retained for audit.
How quickly can GCS mobilise sand blasting in Oman?
For routine work in Muscat, Sohar or Duqm, mobilisation is typically within 2 working days. Emergency and field jobs can be mobilised same-day, with reports issued within 5 working days.
