Different Dampness Protection Methods in Building Construction

Blog |December 8th, 2017

Moisture safeguards exist to create impervious shells around buildings. If that dampness protection system operates as designed, there’s no chance of an ugly leak running down an interior wall, and there’s certainly no way the water can drip-drop through a ceiling. Still, walls are built to stop the bright sun and the cold wind, not this cunning elemental force. Just what building construction method can combat the damp?

Keep Vulnerable Materials Dry 

Before the dampness enters an occupied room, it goes to work on the concealed structure. The wood rots, the plasterboard develops ugly stains, and the structure is compromised. It can cost a fortune to repair this structural damage, so a dampness protection system obviously plays an important role here, one that acts as a potent first line of defence when moisture attacks. Behind that wall, architecturally designed cavities provide a sound defence mechanism. This wall void stops the damp in its tracks.

Provide Rooftop Drainage 

The cunningness of water was briefly mentioned earlier. Damp patches do seem to have a knack for penetrating a structure’s walls. Let’s not make things easy for the invading moisture. If the water is collecting on the roof, install guttering so that the liquid has a clear path off the structure. Otherwise, the dampness will work its way into the tiles and waterproof materials until a leak breaches the roof cladding. Maintain the guttering by employing a service to clean the channels free of old leaves and built-up debris.

What is Damp-Resistant Concrete? 

Certain construction materials look attractive, but they’re loaded with porous surfaces. If that spongy composition is to be addressed, the contractor needs to seal the permeable substance. Special additives and compounds are mixed with the mortar during the construction phase. They damp-proof the concrete, fill the pores, and generally make the building material denser. A moisture resistant barrier is formed when this action is properly utilized. Furthermore, this method can be reinforced by adding a surface coating to the exterior wall surfaces.

If we’re talking about a first line of defence strategy, the just-mentioned method comes to mind right away. Typically, dampness contacts the mortar and bricks, then it penetrates a crack or poorly pointed line of bricks. To stop that penetrating rivulet of moisture, the exterior walls are sprayed or painted with a waterproof compound. That chemical additive could be a lime cement coating, a layer of potassium silicate, a waxy finish, or some other water repelling agent. Incidentally, the waxy, gum-type solutions suggested here cannot be recommended if the building is located in a hot region.
