The channels opened by the companies such as Turkish Telecom, İSKİ, İGDAŞ on the road surface for installation renewal are called trenches. If the sub-layer filling is not carried out and the asphalt is not coated in accordance with the standards, the useful life of the road is shortened and the driving comfort gets worse.

Like the other fields of activity, İSFALT carries out activities complying with the world standards in the field of trench coating. The channels are coated with asphalt in a way that the drivers will not feel the patch and the driving comfort will not be affected.

İSFALT carries out the trench coating for the infrastructure works carried out by İSKİ alone. The work of covering the channels occurring in the roads with asphalt following the completion of sub-layer filling carried out by İSKİ in different parts of Istanbul is performed by İSFALT without changing the level of the road.
