Sub-Floor Ventilated Ground Cover

Sub-Floor Solutions - Was an Innovative - Sub-floor Ventitaled Ground Cover.

Sub-floor Ventitaled Ground Cover was a system I developed in the past, I no longer provide this service.

If your building is damp, exposed to moisture from natural seepage, has musty odours, has excessive condensation etc', then you may consider having our ventilated ground cover installed under the building.

Stephen Koelewyn has developed a way to effectively protect those buildings with a sub-floor (crawl space) from being exposed to ground moisture that occurs naturally under buildings, effectively protecting the buildings interior from moiture occuring to exposed ground under buildings, this reduces moisture levels within a buildings envelope, reduces conditions for mould or fungi that can contribute to musty odours within the dwelling. Makes for a healthier, more durable building.

The sub-floor (crawl space under buildings) is an area in the building that is generally neglected as this is often a forgotten void/s that can be hard to access, an area that can contribute to serious deterioration of the building and/or contribute to sick building syndrome, it can often be difficult to find suitable solutions to reduce the impact of a poor sub-floor environment, with our new Sub-floor ventilated ground cover, we are now able to eliminate this source of moisture from impacting the building. 

Due to the lack of contractors that specialise in the sub-floor areas, the alternatives often involve using either plumbers or pest controllers to carry out repairs in this area, these repairs are often partial and do not necessarily provide a total solution or deal with the source of a poor sub-floor environment. Many recommend to increase ventilation, this reduces humidity to some degree but does not eleiminate the source of the moisture from imacting the building.

Stephen Koelewyn has been working hard on carrying out self funded Research & Development to deal with many of the sub-floor related issues in buildings, Steve has now developed a "Sub-Floor Ventilated Ground Cover" register as an innovative patent in June 2015.

Many building defects and/or problems originate as a direct result of the condition of the sub-floor, the most concerning, is that if certain conditions exist within a sub-floor then the conditions within a building can prove to be a real health hazard to the long term occupants of that building.

Sub-Floor Solutions carries out building services and structural pest management services to improve the environment around and under buildings, primarily to improve the habitable environment within a building and deter termite activity.

Stephen Koelewyn is a licensed builder, licensed pest controller and is tree qualified - Steve has now redirected all his resources to provide a service that has a real lack of specialist contractors in the current market place, due to the market need Steve has decided to re-establish his Sub-Floor Solutions that was very successful in the past.

Sub-Floor Solutions - what do we mean and what do we do.

Does your building have a musty smell internally? A musty smell is often caused by poor sub-floor environment, the musty smell can often be associated to suspended fungal spores in the air within the dwelling, fungal spores are suspected of being one of the possible triggers that can initiate respiratory problems in persons that may have developed a respiratory sensitivity as is the apparent case for some asthma sufferers. Steve has carried out a lot of research and development into improving buildings that are sometimes referred to as having "sick building syndrome", although Steve has explored many of the methods to reduce respiratory triggers such as dust mite control within the dwelling he has found that the interior can be serviced by many cleaning or painting contractors etc'. The sub-floor area is often totally neglected by building owners and can be the origin of many problems within a building and therefore Steve has realised a need to provide Sub-Floor Solutions.

Steve has found that many of the recommendations that he has made and/or continues to make in the reports he provides are not carried out and/or are only partially carried out by his clients, he has been advised on numerous occasions by his clients and/or associates that this is mainly due to a lack of suitable contractors that are readily available and willing to carry out this type of work and therefore Steve has decided to once again provide the services of Sub-Floor Solutions.

Sub-Floor Solutions is a specialised service.

The sub-floor has a significant influence on the internal condition of a building and therefore a good environment within the sub-floor will generally mean healthier living within the habitable areas of the building.

The condition of the sub-floor is affected by many variants and therefore to improve the environment under a building, the surrounds and the exterior of the building often need to be altered.

To improve the environment under a building it is often necessary to undertake major alterations to the existing landscape, site drainage and amenity around the building. The costs involved can be quite high and therefore each and every job needs to be designed and quoted individually.

This page will be developed further with links to individual pages on - Sub-Floor Ventilation, Deterring Termite Damage, Post-Construction Termite Solutions, Tree Root Barriers, Tree Stump Removal, Timber Retaining Wall Replacement.
