Popis:	The main research aim was to determine the feasibility of filling the annular space with cement or other mortar during the renovation of dilapidated drainage networks with one of the common trenchless methods, i.e. by pulling pipes of smaller diameter through them (stalks from a roll). If polymer pipes are used for pulling, justification for the use of filling is necessary, due to their specific properties, which can affect the pipeline system strength and hydraulic performance. The article discusses the need for the pipelines annular space cementation during trenchless repairs.
