Penetrating Damp

Older properties in Hereford are often built without a cavity and have solid walls and if they are affected by water ingress from driving rain, gutter leaks etc they can become damp which can affect walls inside leading to damage to plaster and possible decay of timber.

HerefordDamp &Mould Control offer a complete service for weatherproofing your home which includes roof and gutter repairs, repointing walls and replace defective render with a waterproof coating.

The properties that have solid walls lose about 45% of their actual heat through the solid walls. They are also known as ‘hard to treat’ because insulating them is very expensive. Insulating them through expensive external cladding alters the appearance of the walls and fitting insulated plaster boards internally reduces the room dimensions.

Over 30% of houses currently in the UK are single brick or stone construction (2007 English House Condition Survey).

These can be difficult to insulate when:

• Internal Insulation takes up needed floor space
• Cavity wall insulation isn’t possible
• External insulation can be unattractive and expensive

Hereford Damp & Mould Control

Has a solution to prevent penetrating dampness and also prevent heat loss through walls. We provide external waterproofing treatment with DRYSEAL masonry protection cream. This treatment prevents any moisture ingress and penetrating damp but also reduces heat loss and is also less disruptive to the appearance than solid wall insulation.DRYSEAL is a unique, cost-effective method of improving the water-proofing and insulation qualities of buildings without changing their appearance.

DRYSEAL masonry protection cream repels rain and stops damp penetrating into walls. It reduces heat loss through single skin brick construction, and is scientifically proven to provide heating energy savings of up to 29%. Using DRY SEAL masonry protection cream gives long lasting guaranteed treatment against cold and damp.

The DRYSEAL water-proofing and insulation treatment can be best explained by using the following analogy: Imagine you have been caught in a heavy rain shower with no umbrella. Your clothes are soaked through and very quickly you begin to feel cold. When you get home, your first instinct will be to remove your wet clothes, as you know that they are making you colder.

The reason behind this is that wet materials lose heat more readily than dry materials. In the case of typical building materials, a completely saturated brick will transfer approximately twice as much heat as an identical dry brick.

By keeping a building’s walls drier, it is therefore possible to significantly reduce the heat that is lost through them. DRYSEAL has been developed over the last five years to achieve this by creating a high-performance hydrophobic zone in treated properties.

DRYSEAL is unique cream formulation of silanes and siloxanes, a single coat of DRYSEAL waterproofing and insulating cream is applied externally to masonry using a brush or roller . When applied, the cream is white so that it is easy to see if any areas have been missed. Within 48 hours the DRYSEAL will have penetrated deeply into the walls leaving no visible sign of application on the surface; this means no discolouration, no sheen and no residue.

Any rainwater that comes into contact with the treated walls is deflected away from the building and is seen to bead down the brickwork like water off a ducks back

The Benefits of using Dryseal masonry protection cream

• Keeps walls warm and dry
• Protects your home against penetrating damp (rain penetration). 20 YEAR GUARANTEE.
• Improves thermal performance of masonry by keeping it dry (energy saving)
• Reduces internal condensation
• Improves the performance of cavity wall insulation by protecting it from moisture
• Retains the original appearance of the wall
• Saves up to 29% on energy bills for energy loss through brick surfaces.
• Deep penetration compared to conventional coatings
• Single coat application
• Retains wall breathability
• British Board of Agrément (BBA Certificate 19/5631) approved for 25 years

Applied externally as a single-coat of cream that will last for 20 years, Drysealis a specially formulated cream that penetrates deeply into the walls and reduces the amount of moisture they can absorb. A dry wall conducts much less heat than a saturated (wet) wall does, therefore more heat will be retained within the property as less is transferred out through the walls.

The cream has been formulated to line the pores of the masonry rather than block them, so vapours can still pass through the building fabric allowing it to "breathe." When applied the cream is white, however within 48 hours it will have penetrated deeply into the walls leaving no discolouration, residue or sheen. Tests carried out at two leading UK universities have revealed that as well as preventing penetrating damp the treatment can save a large amount of a property's annual heating energy that would normally be lost.

DrySeal is a BBA approved, unique, thixotropic, water repelling masonry protection cream which we have used on a range of building materials. Dependent on the porosity of the brickwork, the effective siloxane ingredient penetrates the substrate within as little as thirty minutes, where it reacts to become a permanent, chemically bonded, silicone coating, preventing water ingress and heat loss If you feel that your property is affected by penetrating dampness or poor thermal efficiency then please feel free to call us on 01432 629020 for free, impartial advice.

At Hereford Damp &Mould Control we are happy to discuss any damp related problems that may be having an adverse effect on your house and offer over the phone advice or arrange an inspection if required. Initial inspections are also free and we will offer you the most cost effective and beneficial advice and solutions to your rising dampness problems.
