Detailed Product Description

sand bag is a kind of material with high tensile strength, good ventilated performance, high resistance to acid, alkali and microorganism erosion.sand bag is made of 100% polyethylene or polypropylene. It can speed the concretion of soft base and reduce the time of concretion, also can reduce the time and sand volume of construction to use pack drain for  make sand stake in highway,railroad,airport,sea port,dam project for processing soft base. The diameter of pack drain is 10cm and 12cm normally, the tensile strength in CD and MD is more than 20KN/m, the length of pack drain according to the requirement of actual project.
