Method, for forming durable barrier against rising damp in new and existing buildings, has the manifold silicates, in the concrete, sintered by laser energy to block the capillary dispersion of moisture

摘要

To block the capillary spread of moisture in a building construction, especially at ground and cellar levels, a sintered layer is introduced into the concrete material using manifold silicates as rock components in the material. A laser beam is used to deliver the energy to fuse the silicates into an amorphous structure without capillaries and form a barrier against rising damp and which is resistant to hydrocarbons.
