Replacing as many non-porous surfaces with green space as possible will create more areas for natural ground (and plant-based) absorption of excess water.

An air caster is a pneumatic lifting device used to move heavy loads on flat, non-porous surfaces.

Air casters require a smooth, non-porous surface in order to maintain lift and operate properly.

The following steps are used to collect samples for laboratory culture from small non-porous surfaces or objects.

They may be especially formulated for writing on non-porous surfaces such as glass, plastics, etc.

The plastic limit is determined by rolling out a thread of the fine portion of a soil on a flat, non-porous surface.

They tend to perform best on smooth, non-porous surfaces.

Marks can then be cleaned off non-porous surfaces with a damp cloth.

These should be fixed to dry, level, non-porous surfaces.

A similar effect can be observed at a non-porous surface, when sound is bounced off at an oblique angle.
