Pimstone attenuation


#1

HI,

I’m having an ongoing issue on a DAS site, with pre fabricatet bathrooms, where the attenuation is exteme on in the walls like 30db and the walls are 100mm thick, they are made out of standard concrete iron support, the only new thing for me here is the conrete is based on pimstone, does anyone know if this pimstone concrete satturates more than usual?
