Rising Damp Treatments

 What is Rising Damp?

Rising damp is the general term for water that enters the fabric of a building by being absorbed from the surrounding ground into walls and floors – slowly causing damage to a property over a long period of time. This moisture often brings with it, groundwater salts and other contaminants that contaminate building materials and decorations. This is often due to the lack of, or failings of adequate DPC (damp proof course), a physical barrier which allows some water movement by capillary action. If this physical barrier is absent, has broken down or is damaged then it is often possible to install a remedial damp proof course to control water rising from the ground.
Rising damp is a commonly encountered problem in some types of building, however it is often misdiagnosed. It is important that the investigations into dampness are undertaken by a trained and competent surveyor who can recognise and understand the problem. At Homeshield all works carried out by our fully qualified staff is completed in accordance with the latest B.R.E and B.S.I requirements.

Our Cure

Through experience and knowledge of damp and its causes, your local Homeshield surveyor will carry out an inspection and establish the best treatment for your property; this is the initial step to your home being free of damp.

The next step is the cure; our answer is to inject a water repellent cream via a series of holes in the mortar joints using an applicator gun. Once the cream is installed the water within the damp wall will defuse the cream where it is most needed before curing to form a water repellent resin.

Any existing plaster to the affected areas will almost certainly be contaminated with hygroscopic salts. This would need to be hacked off to approximately one meter above the damp stains. These walls can then be re-plastered using specialist plasters. This treatment will re-establish your properties DPC and cure it of any damp.

Wall Tie Replacement

 

wallties

 

According to BRE research out of nine million dwellings constructed with cavity walls, over two million suffer wall tie corrosion or failure and are in need of specialist remedial wall tie replacement. Often the problem is found to be exacerbated by insufficient ties having been installed during construction. This is where Homeshield intervene; our first step in our repair programme is a survey by one of our expert surveyors to determine the extent of the problem.

The position of existing wall ties is plotted using a metal detector and then an endoscope is used to examine their condition. Bricks may have to be removed for the physical examination of sample ties. Homeshields next step is the instillation of replacement ties, we offer a range of alternative wall tie designs is available – resin, mechanical or cementitious depending on the type and condition of the masonry involved. In many cases the existing ties are isolated to prevent further corrosion. Formed in austenitic stainless steel, the replacement ties are available in differing lengths to suit cavity widths up to 110mm. All designs incorporate a centre drip to prevent transmission of water across the cavity.

Damp Proofing

Damp proofing is a general term that covers methods and treatments used to prevent damp from being absorbed through walls or floors into the interior of a property. Issues such as damp and rot can eventually cause structural damage to your property, so it is essential to identify the signs of damp as early as possible to help prevent any further damage. If the physical barrier of damp proofing (to walls or floors) in a property is damaged, absent or bridged in any way it can potentially lead to building problems such as: Wet and Dry Rot and Rising Damp. This is where an expert Homeshield surveyor can help through our quality survey and inspection, our fully qualified and accredited staff will identify any issues and action which may need to be taken. This could be a DPC, Damp Proofing Course a preventative barrier of slate, bitumen or plastic membrane built into the walls of a property, about 150mm above ground level to prevent damp rising through the walls.

Basement Conversions

Basement conversions are a brilliant way to maximise your properties potential and space, the basement is often a forgotten land or no go area in your home, with Homeshield this no longer has to be the case.  At Homeshield use a system of specialist concrete, plastic membranes and pumps to create a dry usable space with lots of headroom, easy access and as much natural light as possible. All of our solutions comply fully with BS8102 and Building Standard requirements.

The membranes cover the walls and the floor and exist to collect the water in one place where it can be pumped into a nearby sewer or drain. The membranes are sealed together to effectively resist the ingress of damp and water. Finally the membrane is completely covered with plasterboard and offers a clean, aesthetically pleasing wall. All services such as electrical cables and pipes are contained behind the plasterboard. Homeshield offer after care and support on all the works we carry out.

Dry and Wet Rot

The main cause of rot is moisture in timbers. Wood destroying fungus feed off this moisture and as a result visible signs of dry rot or wet rot damage appear on the affected timber. Wet and Dry rot spores will only develop and take hold of timbers if the environmental conditions are correct.

dry

 

Dry rot can be problematic to any property so it is essential that you identify signs of dry rot before further damage is done. If you notice the following then it could indicate a dry rot problem:

  • Distinct mushroom smell
  • White fungal growth with yellow and lilac tinges
  • Deep cracks appear within the wood
  • Both soft and hardwood timbers can be damaged

 

wet

 

 

Homeshields professional dry rot service begins with a thorough inspection conducted by a qualified surveyor. This may require removing some plaster, skirting or paneling to establish the full extent of the dry rot and its causes. After a survey has been completed, a solution has been agreed upon and our surveyor has arranged a suitable date with you; our technicians will come and rectify your dry rot problem. Our Homeshield experts will take the following steps to rid your home of dry rot;

  • Stopping the source moisture
  • Removal of damaged area(s)
  • Timbre replacement
  • Treatment of Dry Rot

Wet Rot can be a lethal affliction to any timbres in your home. As with all works we undertake our Homeshield surveyors will conduct an extensive Wet Rot Survey or property inspection to properly assess the extent of the rot problem and decide whether there is a need for treatment. As with dry rot the treatments are largely similar, Homeshield have decades of experience in irradiating properties of rot, both dry and wet.

Condensation and Mould

Condensation is perhaps the most common form of dampness in building and can lead to peeling decorations, unhealthy living conditions and potentially risky mould growth.

When temperatures inside a property drop, the air becomes saturated and can no longer hold onto the moisture created in homes and so it migrates to the coldest surfaces – such and walls and windows.  Some of the more common symptoms of damp are;

  • Water droplets on windows or walls
  • Mould on walls, curtains, carpets, bathroom tiles and window sills
  • Decaying window frames, particularly stained and wet corners
  • Peeling wallpaper
  • Musty/damp smells around the property

Lack of adequate ventilation and modern occupancy styles can lead to a build-up of excessive humidity and moisture. This poor indoor air quality can lead to serious health issues for asthma and allergy sufferers and those with breathing difficulties. At Homeshield we offer a wide and varied range of eco-friendly and innovative ventilation systems, designed to deliver homes with fresh, filtered air.

Structural Waterproofing

wallproof

In basement construction or refurbishment, cavity drain membranes provide an alternative to conventional cementitious tank systems, which work by holding water back. At Homeshield we specialise in structural waterproofing and are able to consider and adapt to the nature of the building and our customers design requirements to ensure that the correct method of waterproofing is selected and executed to the highest standard. Typically cavity drain membranes are installed to the walls and floor this directs water into drainage channels. The channels then allow water to be directed to sumps or drains so that it can be removed safely from the building. . The two types of waterproofing system commonly used in existing structures are: Type A – Barrier/External protection Type B – Integral protection and Type C – Cavity drainage systems.

Timber Treatments and Woodworm

You may not realise that you have a woodworm problem until the resulting damage becomes visible, so early identification is key before they cause more harm. If left untreated woodworm can seriously weaken timber – this may lead to structural failure of timbers.

Not all woodworm species leave the same signs; however, if you find any of the following you could have a woodworm infestation:

  • Fresh exit holes in timber – Round or oval shaped with sharp edges, the holes will appear clean and fresh.
  • Tunnels in wood – (galleries) these are often hard to see.
  • Bore dust – (frass) Caused by emerging adult beetles, usually visible below the infested timber.
  • Weak & damaged floorboards – In extreme cases, a foot or chair leg going through the floor can indicate a more serious problem.
  • Crumbling wood – Around corners or edges to roof joists or floorboards.
  • Dead beetles – Usually found near the infested timber or around nearby windowsills.
  • Adult beetles – They emerge from timbers between May and October.
  • Eggs – These vary in size depending on the beetle, but all are difficult to spot with the naked eye.
  • Woodworm larvae – Usually a creamy-white colour and curved in shape.

 

In order to allow for the best course of treatment, Homeshields experienced and highly qualified surveyors will carry out a thorough inspection of your property. Our treatments will be tailored to your needs as our surveyors will assess:

 

  • The extent of your problem
  • The species of woodworm involved
  • The activity level of the infestation

We at Homeshield offer a variety of treatments , ensuring you get the best quality treatment for your property, below are some of the treatments we use;

Water based treatment – The highly effective and efficient water based treatment allows you to re-enter the treated area, a short time after the treatment is completed. The solution will remain within the layers of timber, cracks, crevices and flight holes to prevent any future infestations.

 

Fogging treatment – Homeshields  unique fogging systems are often used to treat under flooring and floorboards by lifting one length of floorboard across the room for access meaning carpets and furniture are often left indoors during the treatment. Our fogging can often allow the affected room to be back in use within a few hours of woodworm treatment being completed.

 

Fumigation –  is a specialist fumigation treatment  that the process is mainly used for our commercial customers to effectively eliminate all life stages of wood-boring insect with no damage to your business
