I think the waterproofing was done before the moisture could dry out from the slab. Not 100% sure. If I'm correct, we must assume that the slab has cured but not yet dried out to satisfactory levels before the builder sealed it on top with the...
Is it possible to dry out a 300mm thick 30MPa concrete slab with a 25mm polystyrene layer and 75mm screed on top already in position? Area under question - approximately 70m^2. Being an HVAC specialist, the engineer asked me - all I can think of is to de-humidify and heat the air below the slab...
Thank you for your input MarauderX, in South Africa the ambient temperatures rarely reach those low values and often do not last that long - hence the reason why we sometimes forget to include heat tracing. I will however consider the option as we are running water at pretty low velocities as...
Dear fellows,
I am designing a system with common hot and chilled water piping with seasonal changeover. The pipe runs are quite long - about 60m (exposed to ambient conditions). Does anyone know of any special precautions one should take except for linear expansion and proper thermal...
