Slip films offered by Betomax are double-sided HDPE-based films separated by a layer of lubricant. They are foreseen as bearings for small-span flat roofs and for foundations. They are used for monolithic concrete parts and precast concrete parts. Slip film prevents emergence of slots caused by wall leaning.

The following slip film types are offered:

• TG 1 A +b1, TG 1 A +c1 – foreseen as bearings for small-span flat roofs

• TG 1 A +b4, TG 1 A +c4 – foreseen as bearings for foundations

• TG 1 A +b3, TG 1 A +c3 – foreseen as divisions for structural components
