We conduct eleven different parameters like volume and fraction analyses, pH, humidity, water holding capacity, water uptake speed, organic and inorganic matter, dry density and lime with the latest technological and professional equipments order to test their compliance with GLS Quality Control Standards. An analyses report is issued by Quality & Control Department for every shipment after controls. It is able to reach issued analyses reports any time from www.glsgrup.com.tr and from QR codes on pallet labels. Analyses reports are also send to customers via SMS after dispatch from our warehouse.
