A high proportion of damp problems in buildings are caused by ambient climate dependent factors of condensation and rain penetration. [1] Capillary penetration of fluid from the ground up through concrete or masonry is known as "rising damp" and is governed by the shape and porosity of the construction materials through which this evaporation ...
Masonry walls are built with a damp-proof course to prevent rising damp, and the concrete in foundations needs to be damp-proofed or waterproofed with a liquid coating, basement waterproofing membrane (even under the concrete slab floor where polyethylene sheeting is commonly used), or an additive to the concrete.
The DPC in the inner wall is usually below floor level, (under a suspended timber floor structure), or, with a solid concrete floor, it is usually found immediately above the floor slab so that it can be linked to the DPM under the floor slab. This enables installation of skirting boards above floor level without fear of puncturing it.
Concrete has a total embodied energy of 1.69 GJ/tonne, lower per unit mass than most common building materials besides wood. However, concrete structures often have high masses, so this comparison is not always directly relevant to decision making. Additionally, this value is based only on mix proportions of up to 20% fly ash.
When creating hydrophobic concrete through a coating process, a coating is sprayed or brushed onto a porous surfaces. In most cases, it is applied to a regular concrete slab that then undergoes a corrosive process to expose more of the concrete's capillaries. This can be achieved by water blasting the surface at about 3,000-4,000 psi.
After a year, we just decided to remove the old hearth (turned out it was solid cement with a brick exterior) and put in a mantle (FB market), paint, tile, and the whole aesthetic is changed Image ...
In poured concrete foundations, cracks and pipe penetrations are the most common entry points for seepage. These openings can be sealed from the interior. Epoxies , which are strong adhesives, or urethanes can be pressure injected into the openings, thus penetrating the foundation through to the exterior and cutting off the path of the seepage.
It looks like someone is 'surfing' on sod that got a heavy dose of rain on Friday. WHNT reports : Sharon Jeffreys recorded video of her sod 'floating' from three inches of rain that fell on July 18.
