Our tortoise fence is manufactured from HDPE and is available in a wide variety of thicknesses ranging from 30 mil to 100 mil. The material has a smooth surface and resists climbing by turtles and tortoises. The material is installed by digging a trench, placing the plastic vertically in the trench with a portion of the fence protruding out of the ground. The thicker plastics (60 mil to 100 mil) are substantial in thickness and not not require staking to stay in place long term when a large portion of the plastic is exposed. The tortoise fence is manufactured with UV inhibitors to resist breakdown when exposed to sunlight. The fence is available in 100’ rolls and various heights ranging from 18” to 60”. Our tortoise fence is made in the USA.
