Knobbed rolls


	TERRA–MEMBRANA TM-8 N

	TM-8 N with 8 mm knobs The advantageous problem-solution for foundation wall protection and sub-base.

	TM-8 N as a foundation wall protection The high compressive strength of 200 kN/m² and a high tearing strength offer optimum protection of the bituminous paint and the foundation wall when filling the pit. The knobs provide a safe barrier between the foundation wall and the soil and ensure optimal drainage of water, thus protecting the walls against moisture.

	TM-8 N as a sub-base The knobbed roll replaces the lean concrete used up to now. It enables weather-independent working and saves the time required for the concrete hardening. Furthermore, the knobbed roll offers protection against rising humidity. Cement paste cannot flow away.
