The requirementHarmful ground gases entering buildingscan pose health risks. Damp can similarlycause health problems and also damage tothe building fabric.

Protective measures are therefore usuallyrequired in ground floors and theserequirements are enshrined in buildingregulations (see Technical requirements).

Government planning policy requires anincrease in the amount of housing onbrownfield land. This means that muchmore housing will need protection fromground gases.

Current high levels of thermal insulation andmodern construction methods requireventilation within the building fabric toprevent the build-up of moisture andcondensation.

The Glidevale complete solutionGlidevale ground floor protection productsoffer a complete solution:

● A continuous impermeable protectivebarrier against gases from the groundand damp penetration.

● A single barrier avoiding the need for anadditional damp-proof membrane.

● Continuity of protection at edges andpenetrations by means of purpose-designed accessories.

● Ventilation of underfloor spaces and wallcavities to remove gases and moisturevapour where required.

● Easy and reliable installation usingpreformed components.

● Can be used for solid ground floor slabsand for suspended concrete or timberfloors.

● Can be used to meet the requirements ofBuilding Regulations in the UK andIreland (see Technical requirements).

TECHNICAL REQUIREMENTS

GROUND FLOOR PROTECTION, GAS AND DAMP BARRIERS

Harmful soil gasesHarmful soil gases such as methane,carbon dioxide and radon can enterproperties by different routes: throughcracks in floors and walls, constructionjoints, wall cavities, and around servicespipes.

Methane is a colourless, odourless, explosive and asphyxiatinggas.

Carbon dioxide (CO2) is a colourless, odourless, non-flammable,asphyxiating and toxic gas.

Methane and carbon dioxide can arise from landfill sites, mineworkings, and organic-rich soils such as peat or river silt.

Radon is a naturally-occurring colourless, odourless radioactivegas; some parts of the country have higher levels than elsewhere.Exposure to high levels of radon for long periods increases the riskof developing lung cancer.

Building Regulations (England and Wales)Protection against ground contaminantsand moisture are specific requirements ofthe Building Regulations Part C for Englandand Wales. The relevant requirements are:

Approved Document CSite preparation and resistance tocontaminants and moisture

‘Preparation of site and resistance tocontaminants C1 (2) Reasonableprecautions shall be taken to avoid dangerto health and safety caused bycontaminants on or in the ground covered,or to be covered by the building and anyland associated with the building.’

‘Resistance to moisture C2 The floors,walls and roof of the building shalladequately protect the building and peoplewho use the building from harmful effectscaused by:(a) ground moisture(c) interstitial and surface condensation.’

Gases from the groundInformation on methane and other gases isgiven in paragraphs 2.25 - 2.35.Gas control measures are given in 2.36 -2.38. For dwellings these should consist ofa gas resistant barrier across the wholebuilding footprint, above an extraction orventilation layer from which gases can bedispersed and vented to the atmosphere.

HydrocarbonsGround contaminated with hydrocarbonssuch as diesel or motor oils may alsogenerate harmful emissions (not specificallycovered by Approved Document C). Testingfor these is extremely difficult, therefore Glidevale recommend that in such cases aventilated sub-floor void is provided inaddition to a barrier membrane.

Building (Scotland) Regulations

Site preparation3.1 Every building must be designed andconstructed in such a way that there willnot be a threat to the building or the healthof people in or around the building due tothe presence of harmful or dangerous substances.

Harmful or dangerous substances Harmful or dangerous substances includedeposits of faecal or animal matter and anysubstance, or mixture of substances, whichis, or could become, corrosive, explosive,flammable, radioactive or toxic or whichproduces, or could produce, any gas likelyto have any such characteristic.

3.1.6 Risk management techniques There are a range of options for managingthe risk of land that is contaminated. Thiscan include removal or treatment of thecontaminant source or breaking the pathway by which contaminants can present a risk to receptors:

Sealing means that an imperforate barrier islaid between the contaminant and thebuilding and sealed at the joints, around theedges and at the service entries.

Detailed guidance is given in BRE /Environment Agency Report BR 414 Protective measures for housing on gas-contaminated land.

Radon protectionAll new buildings, extensions and conversions in areas where there may be elevated radon emissions may need to incorporate precautions.

3.2 Every building must be designed andconstructed in such a way that there willnot be a threat to the health of people in oraround the building due to the emission andcontainment of radon gas.

Radon protective measures should be provided in accordance with the guidancecontained in BRE publications BR 211Radon: guidance on protective measuresfor new dwellings, and BR 376 Radon:guidance on protective measures for newdwellings in Scotland.

Additional guidance on the installation ofRadon protection measures in dwellings isavailable in two BRE Good Building Guides,GG73, “Radon protection for new domesticextensions and conservatories with solidconcrete ground floors”, and GG74, “Radonprotection for new dwellings”.

Moisture from the ground3.4 Every building must be designed andconstructed in such a way that there willnot be a threat to the building or the healthof the occupants as a result of moisturepenetration from the ground.

CIRIA C665 and NHBC Traffic Lights Protect GDB10 PLUS complies with theNHBC Traffic Lights* and CIRIA C665, wheninstalled as prescribed in BRE 414. (*ForAmber 2 or worse the membrane should always be fitted by a qualified installer orspecialist contractor).

Additional guidance on the installation ofRadon protection measures in dwellings isavailable in two BRE Good Building Guides,GG73, Radon protection for new domesticextensions and conservatories with solidconcrete ground floors and GG74, Radonprotection for new dwellings.

The Glidevale range of underfloor andcavity wall ventilation products enable theregulatory requirements for ventilation to bemet.

● Adaptable to a wide range of situationsincluding different floor depths andremote voids.

● Also provides protection against the entryof driving rain, birds, rodents and largeinsects.

MV250 AirbrickVentilation area 6000mm2

Standard brick face dimensions.Can be stacked in multiples.Driving rain resistant.Can be used with MV251 Periscope andMV253 Vent Pipe Adaptor.Colours: terracotta, buff, anthracite.

MV251 PeriscopeProvides ventilation beneath suspendedfloors.Vertical adjustment for 3-4 brick courses.Suitable for cavity widths from 50 to 100mm.Can be used with MV250 Airbrick, MV254Vertical Sleeve and MV253 Vent PipeAdaptor.

MV253 Vent Pipe AdaptorEnables remote voids to be ventilated viaconnection to 100mm internal diameterpipe.Can be attached to MV250 Airbrick andMV251 Periscope.

MV254 Vertical SleeveFits between two halves of MV251Periscope to increase overall depthadjustment up to 5-6 brick courses.Modular design allows additional units tobe added for even greater depths.

HT2 Airbrick Cavity TrayInstalled above an airbrick to protect thewall cavity against damp penetration inaccordance with BS 8215: 1991.Short length for ease of installation whilstproviding 100mm extension on each side ofairbrick.

MV650 WeepventCavity wall ventilator and weep unit in oneinnovative product.Fits into a single perpend joint.Ventilation area 220mm2.Driving rain resistant and protects againstlarge insect ingress.Colours: terracotta, buff, grey.Can be used in brickwork, blockwork,timber-framed and rendered walls.

InstallationUnderfloor vent spacingLocate underfloor vents on opposite sidesof the building to achieve the most effectivemix and distribution of air flow.

Installed at 4.0m centres they will provide1500mm2 ventilation area per metre ofexternal wall to comply with BuildingRegulations Approved Document C.

However we recommend spacing at 2.0mcentres to avoid the risk of stagnant airpockets and consequent risk ofaccumulation of gases.

Cavity traysBS 8215: 1991 recommends use of cavitytrays above any point where a wall cavity isbridged. Glidevale HT2 or HTR cavity trayswith stopends and weepvents should beused above MV250 Airbricks and MV251Periscopes.

WeepventsWeepvents should be installed on all cavitytrays at 450mm centres.

For timber frame wall cavity ventilation,install at a horizontal spacing of 450mmcentres, at low and high level and aboveand below fire stops in a staggered layout.
