Damp House Assessments, Rising Damp Assessments
Pro Team Group provides a complete damp house assessment we can inspect for rising damp, inadequate subfloor ventilation and moisture and condensation issues in buildings and homes. Once we have indentified and diagnosed the extent of the rising damp, moisture or dampness problem we can then propose the most appropriate treatment to rectify the dampness, moisture issue in your home.
Inspection, Assessment and diagnosis of dampness and moisture problem in homes and buildings
Damp proofing in buildings requires expert diagnosis. Before starting to inject a new chemical damp proof courses or any other damp proofing treatment it is important to correctly diagnose the actual source of the dampness. To establish the cause of the dampness. Is it rising damp? Is it condensation? Is it inadequate site drainage? Is it defective roof plumbing? Is it penetrating damp? If diagnosed incorrectly the incorrect damp proofing treatment will be specified and undertaken and the dampness will not be rectified. It is important a detailed inspection and assessment is conducted of the damp house. Pro Team Group are well qualified to inspect, assess and apply damp proofing treatments and waterproofing as accredited building consultants and licensed residential and commercial builders.

Rising Damp Inspection to identify if it is rising damp
We identify the damp areas using moisture detecting equipment we then assess the cause of the rising damp or dampness in the home or building, we access for condensation and building defects which are making the wall damp.
Using our moisture detection equipment allows us to inspect of moisture in the brick wall determining the extent of rising damp problem.
We inspect for existing an dampproof course and asess the condition of the dampproof course and inspect to see if the dampproof course has been bridge which could be causing the rising damp in the building.
We inspect the level of the dampproof course to identify if the dampproof course is being bridge by soil or built in structures which could be the cause of the rising damp in the home.
We visual look for hygroscopic salts deposits, fretting brickwork damaged mortar and bubbling paints.

About rising damp and how rising damp occurs
In rising damp the salt is carried up by the rising damp into the walls from the soils beneath the building. During dry periods the dampness evaporates from the walls the salts unable to evaporate are left behind.
Rising damp occurs at the base of walls. It is caused by capillary suction of the fine pores or voids in masonry materials drawing water up from the soils beneath buildings.
Modern construction methods prevent rising damp and dampness rising through the installation of damp proof courses.
However many older buildings and homes were built without damp proof courses, or due to failure or bridging of the damp proof course we now find problems with rising damp at the base of walls.
In most cases where dampness occurs there will be the association of salt attack with it. Salt attack decays brick, mortar, stone and other masonry materials by soluble salts forming crystals within the pores of masonry.

Salt removal from brick walls and rising damp remedial works
We provide the service of salt removal from brick walls associated with rising damp in Melbourne.
Chemical injected damp course to stop rising damp
Pro Team Group inject a new chemical damp proof course into damp masonry to control and stop rising damp. Once the fluid has dried Pro Team Group replaster the effected walls and complete all other building and construction works as required providing a complete rising damp rectification service.
Problems associated with rising damp and salt attack
- Rising damp causes damage to masonry materials including stone, clay bricks, concrete blocks and mortar.
- Severe structural damage can be caused by salt attack caused by rising damp.
- Other effects of salt attack and rising damp can be crumbling bricks caused by salt attack and rising damp.
- Mortar erosion and damage caused by salt attack and rising damp
- Fungal decay to the timber framing and timber skirting boards due to high levels of moisture from being in direct contact with brickwork affected from rising damp.
- Peeling and bubbling and damage to paintwork on walls affected by rising damp.
- Failed dampproof courses do not provide protection from dampness and moisture from penetrating timber subfloor framing which can cause fungal decay/ wood rot, and increase the chances of timber pest attack to damp timber.
Sources of dampness which may contribute to rising damp, damp subfloors and mould growing in your home.
- Site drainage which may be contributing to the rising damp
- Defective roofing, defective leaking or inadequate gutters and downpipes which may be the cause of the dampness to the brickwork or be increasing pressure of the rising damp.
- Poor or inadequate subfloor ventilation and humidity problems which may be the cause of the dampness or increasing the pressure of the rising damp.
Bridging of damp proof courses
- Rising damp may occur due to the existing dampproof course being bridged which may occur from:
- Paving being build up higher than the dampproof course which is the cause of the rising damp.
- Landscaping and garden beds being built up higher than the damp proof course which is the cause of the rising damp.
- Damp proof course can be bridged in the construction method of a cavity brick wall mortars and debris built up in cavity walls can bridge across brick cavity walls from the external brick wall skin to the internal brick wall skin which may create dampness on the internal skin of the brick wall. This bridging of the damp proof course may occur with penetrating damp/lateral damp and rising damp.
Injecting of dampproof liquid to stop rising damp
Pro Team Group inject a a new chemical damp proof course to stop rising damp. Once injected the new chemical damp proof course creates a barrier stopping rising damp occurring.
Highly effective formulation enables long lasting and deep penetration creating a new damp proof barrier stopping rising damp. All efforts are taken to limit the disruption to your home or place of business. Pro Team Group professionally install a new chemical damp proof course which is safe to your family, your employees and the applicator of the installing the dampproof course to stop rising damp.

Procedures of the installation of the new chemical injected damp proof course to stop rising damp.
Pro Team Group remove the skirting boards and plastering to the walls where rising damp is a problem and where the new damp proof course is to be installed. Timber skirting boards in poor condition damaged by fungal decay and rising damp will be disposed of and new skirting boards will be chosen to be installed which matches the existing skirting boards of the house. Where the skirting boards are in good condition they will be retained and reinstated once the successful rising damp treatment is completed.
Pro Team Group replace damaged bricks and replaces fretted and affected mortar damaged by the rising damp and salt attack prior to the installation of the new chemical damp proof course.

Drying Periods of walls once rising damp works are completed
Once the new chemical damp proof course has been installed to the wall with rising damp problems drying of the chemical damp proof course takes approximately two weeks if reasonable temperatures and ventilation within the home or building is provided. In special circumstances the drying periods may change or take longer.
The masonry wall which had the new damp proof course installed to stop rising damp will require drying out as dampness will still be within the wall. Natural drying out of the brick wall affected by rising damp once the new chemical damp proof course has been installed depends on the retained salt content within the wall, the ventilation available within the building, the temperature and the humidity.

Replaster with the rising damp treatments
Pro Team Group can make repairs to internal plasterwork once a the new damp proof course has been installed and the source of the moisture has been stopped.
Replaster with the rising damp treatments
Pro Team Group can make repairs to internal plasterwork once a the new damp proof course has been installed and the source of the moisture has been stopped.
Pro Team Group remove plaster and reinstate new plaster using a salt retardant additive once the new chemical damp proof course has dried out. Additives are added to the plaster which makes the plaster retain salts but still allows the drying of the wall. When removing the existing plaster we allow 400mm higher than the highest point of detected dampness to achieve maximum drying.
Where the brick work is not plastered we will fill the drill holes used to inject the new chemical damp proof course with mortar with a waterproof additive.

Drying Periods of walls once rising damp works are completed
Many houses suffer from poor or inadequate subfloor ventilation Pro Team Group conduct a detailed inspection of the property, house and subfloor area to access the extent and cause of your subfloor ventilation and/or dampness problem. The main reasons for inadequate subfloor ventilation include:
• Design and construction issues can restrict cross flow ventilation which can create poor or inadequate subfloor ventilation. This is very common where buildings are attached or semi attached to other buildings and structures;
• Subfloor ventilation problem due to mechanical ductwork.
• Left over building debris and other items in the subfloor area can restrict cross flow ventilation and create subfloor ventilation problems which can create excessive moisture and mould in the subfloor area and in the house.
• Subfloor framing constructed too close to the ground doesn't allow enough space for cross flow ventilation creating poor subfloor ventilation.
• Garden beds and paving build up over subfloor vents is also common which restricts subfloor ventilation.

Rectifying subfloor ventilation problems
The environment and the extent of the subfloor ventilation problem will be assessed after a detailed subfloor inspection. We will then recommend the best solution to your subfloor ventilation problem.
Solutions for poor or inadequate subfloor ventilation include installation of extra subfloor vents or changing the existing subfloor vents in your home to a different kind of vent which allows a larger volume of air flow to enter and extract from your subfloor area.
Solutions for poor or inadequate subfloor ventilation include installation of extra subfloor vents or changing the existing subfloor vents in your home to a different kind of vent which allows a larger volume of air flow to enter and extract from your subfloor area.
For more serious subfloor ventilation problem we install a system consisting of a in-line exhaust fan capable of heavy usage which is set on a timer to operate during the day or at a time to suit the occupiers of the home. Ductwork is used to extract and introduce fresh air to the subfloor area. The whole subfloor ventilation system would typically be installed under the floor but it can be placed in other areas with ducting to the area requiring ventilation.
Subfloor ventilation and rising damp
Poor inadequate subfloor ventilation does not allow damp soil to evaporation or to be remove from the subfloor area via cross flow ventilation which can create greater moisture stress on brickwalls, brick piers and subfloor timber framing. Controlling water evaporation in the subfloor area will help the control of rising damp. Cross flow subfloor ventilation will introduce external air into the subfloor area and push out damp, moist and stale air from the subfloor area.
Mould can become a serious problem with damp buildings and homes. We identify the source of the damp problem and fix the source of moisture and dampness to stop mould growing
About mould
Mould growth can occur where dampness and excessive moisture is present in your home or building. Moulds release countless tiny spores which travel through the air. If mouldy items and materials are not removed or correctly cleaned high levels of airborne mould spores pose a health risk to the occupants of the building. Mould can trigger asthma attacks and aggravate other respiratory and allergic conditions.
If you think you may have a medical condition due to mould consult a medical practitioner.

What to do if you have a dampness and mould growing in your house
Professional mould removal
Mould needs to be professionally removed as the spores become airborne and are easily inhaled. Just as important though is to establish the cause of the mould, dampness and excessive moisture within the home. The problem can be design related or due to a defective component of the building. Through a detailed inspection and assessment it is possible to establish the cause of the dampness and through remedial building works remove the root of the dampness problem.
Condensation and mould growth
Condensation can cause mould growth in houses which in turn attracts fungal decay in timbers and the timber structure of a house or building. Ventilation is an effective way of reducing or removing moisture within a house. Effective ventilation reduces relative humidity within a building.
Mould growing under houses and under buildings in the subfloor area.
Mould is common in the subfloor area when there is excessive moisture and dampness. Pro Team Group has solutions for dealing with mould growing under house in the subfloor area.
Ventilation is an effective way of reducing or removing moisture within a house and in the subfloor area of a house or building. Ventilation can reduce relative humidity within a house and in the subfloor area of a house. Subfloor ventilation increases air changes under a home or building creating a healthier living environment.

Ventilation can reduce relative humidity within a house and in the subfloor area of a house. Subfloor ventilation increases air changes under a home or building creating a healthier living environment.
Why condensation occurs
Warm air holds more moisture than cold air. If air is warm enough to store a considerable amount of moisture and if the air is cooled below dewpoint, relative humidity exceeds 100% and condensation occurs.
Condensation can occur where moisture levels are too high.
Condensation can occur where moisture levels are too high.
- Water vapours from a source to an area of cold temperature.
- Temperatures in the building fabric are too low.
- Dampness will increase the humidity level within a house or building contributing to condensation occurring.
