In Sydney if we seal our home completely, we should only get fresh air inside when we open a door or window. To exhaust unwanted smells, water vapour and pollution, and replace them with fresh airwe need roof ventilation, but we also need to control ventilation so that we can turn it on and off as we need it and direct it where it is necessary.
A sub floor refers to an extra level of flooring that is positioned right on top of the floor joists, and another level of flooring is then placed over it which is the visible floor. In Sydney sub floor is usually added to a building so that the floor remains even and flat and also to increase its stability.Once you realize that your floor has mould and that there is a stale smell in the rooms of your home, then you may be in need of immediate sub floor ventilation in Sydney. Dampness causes moulds that attract termites which end up destroying your floor.Moulds can also discolour the tiles of your floor and the bricks that make up your home so mould removal in Sydney is necessary. Sub floor ventilation is therefore important to in reducing the maintenance costs of your home and also in retaining its value.
The vertical flow of water up through a permeable wall structure is defined as Rising damp in Brisbane buildings. In this the water is derived from the ground water. "Capillarity” is the process in whichwater rises through the pores (capillaries) in the masonry. The masonry acts like a wick in other words.Deterioration due to age and bridging of a damp course with internal concrete floors, renders or external paths and earth levels are the common causes.
When it comes to rising damp treatment, membrane systems like the ones provided by John Newton and Company are considered to be an effective alternative to most conventional damp proofing methods such as chemical damp proof courses (DPCs), cementitious and bitumous paint on coatings and external water repellents. This is because membrane systems generally require minimal preparation, are quick to install, and are considered to be most sympathetic to the structure.
They are reversible and can be ventilated which make them particularly ideal for use on conservation and historic projects as well as for refurbishment, renovation and new build where rising damp treatment is required.When an injected damp proof course is used in damp walls where rising damp treatment is needed, part of the process almost always includes hacking off existing plaster which is an extremely messy process. Damp proofing membranes can be applied over most existing wall finishes without the need to remove them as a rising damp treatment.
The membranes are offered up to the walls, drilled and fixed quickly and cleanly the same way to almost any substrate as no guess work is required. Without changing the status quo of the wall the internal finishes which require rising damp treatment,the damp-proofing membranes provide an impervious barrier to protect them.
