Building a new home provides the opportunity for preventing indoor air problems. However, it can result in exposure to higher levels of indoor air contaminants if careful attention is not given to potential pollution sources and the air exchange rate. Indoor air quality can directly impact the quality of one’s health. Poor indoor air quality can impact asthma or cause irritation to eyes, nose, and throat. Incidences of nose dryness often leading to nose bleeds, skin rash, headaches, upper respiratory distress, and dizziness.
Shotcrete home concrete is stable throughout its life and does not need chemical treatment to protect it against rot and insect attack: this means that there are no emissions in the internal environment.
Avoidance of mold
Molds can be found almost anywhere; they can grow on virtually any organic substance, as long as moisture and oxygen are present. There are molds that can grow on wood, paper, carpet, foods, and insulation. When excessive moisture accumulates in buildings or on building materials, mold growth will often occur, particularly if the moisture problem remains undiscovered or unaddressed.
It is impossible to eliminate all mold and mold spores in the indoor environment. However, mold growth can be controlled indoors by controlling moisture indoors.
The walls of a Shotcrete home have no cavities, no where for mold to grow and act as an air barrier. This helps improve indoor air quality by limiting the amount of moisture that can enter a building or wall through infiltration. It also provides better control for the heating, ventilating and air-conditioning.
