Varieties of geo-synthetics are present and engineers use it both in construction and engineering. Consequently, the things that should be considered are use, function and property. The main characteristic of geo-synthetics is that there should be used raw materials but the final products should be very compact and consistent. Additionally, when constructor should worry and care about the budget, the geo-synthetics offers new possibilities and opportunities. So, new way and new methods come into the first plan. There are eight types of geo-synthetics. In civil engineering, they use one of these types.
