The second problem is damp. Typical mortar walls made from brick or concrete will soak up moisture from outside. This water will then be attracted to the inside of the building causing damp. If left untreated; damp can case rotting to fixtures within the building such as wood, paint and carpets.
So it's important to make sure your new walls are thoroughly insulated so damp doesn't become a problem. If damp does settle in it'll cost a lot of money to repair the damage. In this article we'll cover the steps you can take in order to protect your building from damp by building a good, solid structures.
When constructing cavity walls you normally have an inner and outer wall. Cavity walls are built to have a small gap between the two walls to offer insulation. The problem is because the gap can attract moisture from outside; damp can become a problem.
By using cavity wall ties the moisture that's attracted from the outside is prevented from entering the inside of the property by using drips and sometimes insulators. It's also important to make sure damp proof courses are installed at ground level to prevent damp coming up through the fixtures.
Cavity wall ties are spaced on top of the first course of blocks 900mm apart and then spaced at 450mm vertically as the block work rises. Cavity wall ties have a drip built into them which prevents the outside moisture from entering the inside layer. Most ties will have a plastic clip to hold the insulation in place. In older buildings where unprotected metals were used on the wall ties the metals may corrode. This can cause building structures to become unstable and the insulation to become ineffective. Remedial wall ties offer the best solution where metal ties have corroded away.
Remedial wall ties can be drilled into walls that have cracks or have become misaligned due to the ties being corroded or damaged. They're fairly simple to install with a drill and can prevent dampness in buildings as well as providing extra strength to the structure.
So if you're building a wall in your property make sure it's built properly. Modern legal requirements require insulation in buildings so energy isn't wasted on heating the property. Properly insulated walls will also prevent damp from occurring.
