One of the common families of moisture intrusion in dwellings, rising damp is relatively simple to visually diagnose. However, investigating the extent of the rising damp and the source involves a heavy investment in moisture identification equipment.


Rising damp


Primarily found in sold brick dwellings, rising damp is caused by either an overwet subfloor due to a leaking pipe, broken or non existent drainage or storm damage, or a poorly ventilated subfloor which causes the moisture which exists naturally in soil, to affect the building envelope. Regardless of the source, the cause of the damage internally is excessive moisture in the subfloor. As the moisture evaporates, it wicks up through the porous mortar and bricks and causes the solid plaster walls to deteriorate and start to disentigrate.

Often the resolving of the causes of rising damp can be difficult to achieve due to a lack of access to the subfloor, and in this instance it is vital that correctly identifying the source and extent of the rising damp so that remedial action can be undertaken.


Horizontal damp


Horizontal damp is generally caused by garden beds or soil which is butting uo the the external walls of he dwelling and in some instance, the land is higher than the building wall. In these instances damp wicks horizontally into the building envelope.

The equipment required to investigate rising and horizontal damp is the same equipment that is required to identify moisture within the building envelope. In the absense of access to the subfloor, then inspection cameras are vitally important.



1. Flood through equipment breakdown, storm and rising water

Water from these sources can be classified as either Category 1 (clean), Category 2 (general contamination) or Category 3 (sewerage) and we have the equipment and knowledge to quickly remove flood water from any dwelling. Speed is of the essence in attempting to avoid the negative consequences of water in the dwelling as if left, it can lead to mould, distorted timbers, condensation and long term damage to furniture and general belongings.


2. Moisture (visible and hidden) caused by a lack of ventilation

More difficult to reverse, often the symptoms of a lack of ventilation - rising damp, mould, mildew and condensation - have taken years to manifest themselves and can take several months to reverse unless radical action is taken.



The trick to any water damage salvage operation is fast action - and identifying all moisture laden areas of the dwelling, including invisible moisture, is paramount to the erradication of it.

Our moisture identification equipment and techniques will quickly and efficiently identify all moisture in the building and the entry points. This is achieved via infra red inspection technology which identifies temperature differences deep into building materials, concrete inspection metres, plaster and timber inspection metres and atmospheric moisture identification metres. In the absense of access to the subfloor then inspection cameras can identify and locate the boundaries of the moisture damage.



Step 1 - Identify the source of water breach and stem the moisture source

The first step in any moisture reversal or erradication process is to stem the source of the moisture. If this is an' event' type of invasion (flood, damaged rains), then the first step is to ensure that the event has been repaired. The source of the water breach must first be identified and our impressive array of moisture detection equipment can quickly identify all water breaches even if not immediately visible.

Step 2 - Identify moisture contamination

Our sophisticated equipment can quickly identify the presence of all moisture and water contamination in plaster, concrete and all porous materials, as well as atmospheric moisture distortions.

Step 2 - Dry the building

Our sophisticated equipment can quickly identify the presence of all moisture and water contamination in plaster, concrete and all porous materials, as well as atmospheric moisture distortions.

Step 3 - Remove and/or reverse the symptoms of moisture

Once we have stabilised the situation, we then clean up all mould affected areas of the dwelling, and dry out the building using dehumidifiers, airmovers and large gas fired heaters.

Step 4 - Increase the ventilation

If it is a lack of ventilation (as opposed to an event) then the first step is to increase the ventilation, typically through a combination of forced or mechanical ventilation and adding passive vents. Often, if the moisture in the subfloor (moisture is typically found in the subfloor of the dwelling) is severe, we adopt a radical approach to its reversal and will dry out the subfloor before installing a long term mechanical ventilation system.
