Concrete is one of the most commonly used materials in home construction. When pockets of air are not removed during construction, or the mixture is not allowed to cure properly, the concrete can crack, which allows water to force its way through the wall. Foundations (footings) are horizontal pads that define the perimeter of foundation walls.
[4]: 178 Moulds can grow on almost any surface and occur where there is a lot of moisture from structural problems such as leaky roofs or high humidity levels. [5] Airborne mold concentrations have the potential to be inhaled and can have health effects. [6] Externally, mortar may crumble, and salt stains may appear on the walls.
Pouring a concrete foundation. The design and the construction of a well-performing foundation must possess some basic requirements: [2] The design and the construction of the foundation is done such that it can sustain as well as transmit the dead and the imposed loads to the soil.
Mold on houseplant soil may look problematic, but it’s easy to reverse the damage. Take these steps to cure your moldy houseplants and prevent future infections.
Damp proofing in construction is a type of moisture control applied to building walls and floors to prevent moisture from passing into the interior spaces. Dampness problems are among the most frequent problems encountered in residences. DPC visible between concrete foundation and brickwork.
Epoxy moisture control systems can be applied over concrete with relative humidity levels up to 100%, and there are systems available on the market today that can be applied over concrete that is physically damp. In some cases, with the use of an epoxy moisture control system, floor coverings can be installed just 7 days after the slab is poured.
The original foundation isn't strong or stable enough. The usage of the structure has changed. The properties of the soil supporting the foundation may have changed (possibly through subsidence) or were mischaracterized during design. The construction of nearby structures necessitates the excavation of soil supporting existing foundations.
A foundation must bear the structural loads imposed upon it and allow proper drainage of ground water to prevent expansion or weakening of soils and frost heaving. While the far more common concrete foundation requires separate measures to ensure good soil drainage, the rubble trench foundation serves both foundation functions at once.
