TYPAR SF
Typar SF is a filtration canvas, which is composed with thermally bonded continuous polypropylene filaments.
Properties of Typar SF:
• Lets through water and air
• Separates soil from structures
• Filtration ability, preventing soil particles to get into the structures
• Strengthens soil
• Prevents roots spreading
• Stops soil erosion
