Laying onto existing substrates

Footfall sound insulation on problematic substrates


By installing a decoupling system reliable, defect-free results are achieved when laying ceramic covers onto problematic substrates, such as timber floor boards, OSB and chipboards, mixed substrates, young concrete or cracked screeds. Repair works frequently also demand the installation of sound insulation. The BOTAMENT Footfall Sound and Decoupling Membrane achieves a footfall sound reduction of 13 dB, tested in accordance with EN ISO 140-8.
