Rising Damp Herefordshire

When it comes to rising damp treatment, here at WYE VALLEY HERITAGE BUILDING SERVICES IN HEREFORD, we offer a number of courses to suit your needs. Systems like the ones we provide 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. We offer a number of courses, but we can advise you on the spot which will be the best suited to your problem, our experts are fully qualified to deal with any issues you have. Our systems generally require minimal preparation, are quick to install, and are considered to be most sympathetic to the structure.


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 disruptive and messy process. Drilling and injecting the chemical DPC is an exact science in that the holes have to be drilled to the right diameter, at the right spacing and to the correct depth if the installation it to be effective. The exact gauge of DPC cream or fluid in relation to the thickness of the wall and what it is built from need to be calculated and used to achieve totally effective diffusion into the substrate which is especially tricky in buildings constructed of varied materials or poorly built structures where there are large fishers and voids. No guess work is required and the membranes are offered up to the walls, drilled and fixed quickly and cleanly the same way to almost any substrate. The damp-proofing membranes provide an impervious barrier to protect the internal finishes which require rising damp treatment, without changing the status quo of the wall.


If a DPC fluid is used then the active ingredient is mixed with water as the carrier and so you are effectively introducing more fluid into an already damp wall thus making it wetter! If there is any organic material like timber (skirting boards, door linings, architraves, fixing blocks etc.) in contact with the damp wall then there is a risk that wood rotting fungi like dry or wet rot could germinate and in many cases cause serious decay. Dry rot treatment in particular can be very disruptive and expensive. Damp timber will also promote and harbour wood boring insects more commonly known as woodworm. Infestation by wood boring insects can have a detrimental effect to the timber which may result in the need to completely remove and replace the item or wood worm treatment by a specialist wood worm treatment company may be necessary. Membrane systems completely isolate the decorative joinery and timber items from any dampness in the walls thus prolonging their longevity.


Another advantage for using us as your provider is that we know other injected chemical DPCs as a rising damp treatment, chemical DPCs are almost always installed with a recommendation to re-plaster the wall at least to a height of 1.2m with a dense plaster and with a salt retardant additive in the plaster mix. The plastering will be considered by the contracted damp specialist to be as vital a part of this system as the chemical DPC and therefore achieving the right combination of sand, cement and salt retardant additive is absolutely crucial if it is to achieve its design function. Damp Specialists will rarely give a guarantee for the work if the associated salt retardant plastering is not done and if it is done by someone else then the end user faces a split responsibility situation if something goes wrong in the future. We guarantee that your damp proofing course will be done correct!


We can use Damp proofing membranes. Damp proofing membranes factor out human error when it comes to application of the injected damp proof course and the associated re-plastering when used as a rising damp treatment, or for dealing with other damp problems. Damp Proofing Membranes are a physical product manufactured identically at source and once applied to the wall are guaranteed to protect the internal finishes from dampness and salting. They do not rely on correct mixing and a level of chemical reaction and performance to be effective. Depending on what you are looking for from us at WYE VALLEY HERITAGE BUILDING SERVICES, we guarantee customer satisfaction. So feel free to call.


Attempts to combat penetrating damp with cementitious or bitumous products often fail due to a lack of effective preparation work, with us nothing fails. The products we use are as good as the surface to which they are applied and therefore exhaustive and very thorough preparation of the surface is required prior to their application, we make sure to do the job correctly. This can be disruptive time consuming and expensive, but with us we are cost effective. They need to be applied 100% defect free to be effective and often defects cannot be seen due to the nature of how the products have to be mixed and applied. As a rising damp treatment, or a treatment for many other damp problems, here at WYE VALLEY HERITAGE BUILDING SERVICES we have the ideal solutions.


We have damp proof courses to suit your needs. Where external ground levels are higher than the internal floor levels such as in a damp cellar then there is a risk of hydrostatic water pressure and damp proofing walls only will be a futile exercise if a running water situation occurs. Here at WYE VALLEY HERITAGE BUILDING SERVICES we know how to spot this immediately. Therefore whenever there is a situation where earth is bearing against the structure and making the wall damp a damp proofing membrane chemical damp course alone should not be considered and would not conform to BS8102 (British Standard for The Protection of Structures From Water From The Ground). The remedial method adopted should be a waterproofing system design and application.


Thus one of WYE VALLEY HERITAGE Damp Proofing courses would be the permanent and effective product to use as your rising damp treatment, and for many other damp problems. For information about the full waterproofing product range call 07713279819.

What actually is Damp and why do you need professionals? Damp is moisture that is present in the structure of a property. We are based in Hereford and cover all the surrounding areas, please feel free to phone for a full validation. Damp can be caused by rain water and appears in the bricks and mortar. As the UK experiences 25,000 gallons of rain water each year, damp is one of the most frequent problems encountered in homes. Yet, the problem can also arise from a lack of poor property maintenance concerning the floors, doors, windows and pipe-work. The presence of damp can cause all sorts of issues ranging from colder temperatures and the degradation of a property's interior to risks of mould and more seriously, aggravated respiratory problems. Minimising Condensation Condensation is the only cause of damp that you can partially manage. Here are some tips: • Produce Less Moisture in Your Home There is always some moisture in the air but adding to the amount will only increase the likelihood of damp. Dry clothes outside instead of on the radiator, have the windows open when bathing and showering and keep lids on the pans or use a ventilator when cooking. • Ventilate your Home Keeping windows slightly ajar can help to reduce the natural moisture that occurs from breath. Make sure bathroom and kitchen doors you only open when needed. Leave space between furniture and the walls to allow air to circulate. Investing in a dehumidifier is also a great way to remove moisture from your home. • Heat, Insulate and Draught-Proof your Home The warmer your home, the less likely the presence of condensation. Keep your home heated as much as you can and install insulation and draught-proofing measures for the loft, walls and windows to keep your home warmer for longer. Double glazed windows are another effective option. What are the Signs? As damp can be quite a problem, it's a good idea to keep a look out that it isn't effecting your property. When attempting to spot signs of damp, look out for: • Wallpaper or paint that is peeling away from the wall • Skirting boards that have become discoloured or decayed • Decayed Timber floors. • Discolouration & the crumbling of plaster Yet, damp does not always make itself as obvious as this so if you're still worried that it's present in your home, call us at Wye Valley Heritage to carry out a specialist inspection. Damp Proofing If your building has a history of or is suffering from a damp problem, it's a good idea to start alleviating the situation before it spirals out of control. Damp proofing most often requires a professional hand and depending on the type of damp situation, it could involve one or more of these measures: Damp Proof Course: This is the course most often taken for cases of rising damp . The process involves drilling holes into the brick of the property's internal walls and injecting the structure with a damp-proofing fluid to lessen the movement of water through the wall's capillaries. The course acts as a barrier to moisture rising from the ground and passing into the walls. Choosing this route will also involve the need to re-plaster the walls. Structural Waterproofing: This system involves the incorporation of a drain membrane into the walls and floors. It is the best remedy for damp problems that are caused by high ground levels. Once the membrane has been installed, the presence of damp is managed as the moisture can run down the membrane and be channelled into a drain. Cementitious Tanking: This process involves coating the internal walls of a property to seal moisture out of the home. This technique is useful for general moisture but ineffective for situations such as flooding. Three coats are applied and then the wall re-plastered.

Damp Proofing, Herefordshire
2 November 2020
This country cottage residence situated in little birch Hereford, was in need of updating, while suffering from water ingress along with the deterioration of the internal masonry and decorative finishes. This was caused mainly from a lack of maintenance over a period of years, a combination of failing gutters, down pipes running out into the surrounding ground with blocked and collapsed drainage, water buts against the house walls without piped overflows in operation and high soil levels. A shed was positioned against the rear house wall with the shed roof pitched falling back toward the house and the rear elevation house wall was subject to the run off of water from the shed roof. There were also bricks missing that became obvious once the shed had been removed, revealing water ingress. The cottage was constructed of a solid brickwork construction and painted with non breathable paints
