Core drilling for mining, hydrogeological (water) drilling and geotechnical engineering since 1994. Founded by two geological engineers, the company now works across Turkey with 13 drilling rigs.
01
The engineer who drills is the geological engineer who writes the report. We work for public bodies and the private sector as main contractor or subcontractor.
Mining · coal
Drilling with high core recovery on all kinds of mineral and coal sites, at inclinations from 45° to 90°.
Hydrogeology
Groundwater for drinking, irrigation, domestic and process use. Development with a compressor and pumping tests with a submersible pump for maximum yield.
Geotechnics
Engineering parameters of the ground, from drilling combined with packer (Lugeon), permeability, standard and cone penetration tests.
02

G&M Mühendislik Sondaj Taahhüt Sanayi ve Ticaret Ltd. Şti. was founded in July 1994 as a partnership of two geological engineers. It started with groundwater exploration and deep water wells; today it drills in every branch of geological engineering.
Our core principles are a professional work ethic and reliability. We believe successful drilling depends on knowledge, experience and good equipment, so experienced engineers and technicians work in our team. We can cite every project we have been part of as a reference.
Health and safety
Complying with occupational health, safety and environmental regulations is a non-negotiable condition at all our operations and sites. The health of our employees, clients, suppliers and partners is our priority.
