| Material | Typar PRO 125 is a thin, thermally bonded, water-permeable nonwoven geotextile made of 100% continuous Polypropylene filaments. It is designed to have a combination of a high initial modulus (stiffness), high elongation (typically >50%) and outstanding uniformity to make it resistant to damage and to have excellent filtration properties. It is resistant to rotting, moisture and chemical attack, particularly alkalis. Predicted to
be durable for a minimum of 100 years in all natural soils.

Application
| In building construction, laid on top of the thermal insulation of terrace roofs (in inverted flat roof structures), it prevents fine gravel particles from getting in between the XPS boards, protects the thermal insulation or waterproofing from mechanical effects. When installed in green roofs, it prevents humus from washing into the draining and water retaining
TERRAPLAST® PLUS 20-P dimpled sheet or provides root protection. According to its mechanical and drainage properties, it can be used in ground works (e.g. under sport fields, parking areas, temporary roads, roads with moderate traffic).
|
| Rules of installation | Plain and free of sharp gravels surface is necessary for the laying TYPAR with free, at least 30 cm width overlapping.
Not to be laid in viscous clay or silt. Product should be covered after 2 weeks of installation. Good resistance up to several months in direct sunlights, but prolonged exposure can cause strength losses.
