Clay Heave Protection - Jablite

Easy to handleClaymaster is manufactured from expanded polystyrene (EPS), and is lightweight and easy to handle. The useof Claymaster satisfies the recommendations of the Building Research Establishment (BRE), and the NationalHouse Building Council (NHBC) in using compressible materials to relieve clay-heave pressure.ApprovalsThere are no specific requirements in the Building Regulations for the use of compressible-fill materials.However, there is a general requirement (Regulation A2) which states that ‘buildings shall be constructed so thatground movement caused by swelling, (or) shrinkage ...of the subsoil... will not impair the stability of any part ofthe building’.Claymaster has been assessed by the British Board of Agrément according to Regulation A2, and found toreduce the effects of the expansion of clay soils which might impair the stability of a building. It has beenapproved for use underground beams and against the sides of deep-trench fill foundations; Certificate number90/2543.The NHBC Standards, Chapter 4.2, ‘building near trees’, states that low-density compressible polystyrene is asuitable proprietary material to alleviate ground pressures on foundations in shrinkable soils.GradeClaymaster is a special low-density expanded polystyrene. It is coloured pink for ease of identification.DimensionsStandard size: 1200 x 2400mm, and 600 x 2400mm.Thickness: 50, 75, 100, 150 and 200mm.Additional widths (eg, 400, 450 and 500mm) are also available.ShapeBoards are normally rectangular and of uniform thickness, but special shapes are available to order includingcircular sections to fit around pile caps, and tapered boards.AccessoriesSpacing blocks to ensure correct cover to steel reinforcement must be of a type and quantity to preventpenetration into the surface of the Claymaster; the imposed pressure on the Claymaster should not exceed15kN/m2.Fire PropertiesIn common with all organic materials, EPS is combustible. However, provided it is specified and installed correctlyand in accordance with the manufacturer’s instructions and BS 6203, it will not present any undue fire hazard.CombustionEPS is ‘combustible’ as defined in BS 476:Part 4. When burning, EPS behaves like other hydrocarbons such aswood and paper. For Euroclass F material, the products of uncontrolled combustion are carbon monoxide,carbon dioxide, styrene, and water vapour; the decomposing styrene will give off a certain amount of denseblack soot. Euroclass E material also emits hydrogen bromide when burning.Floors | Walls | Roofs Jablite Claymaster Technical Information 4

Ignition temperatureFlash ignition temperature is between 350 and 490ºC depending on the application and the exact circumstancesof use. Under certain circumstances the material can be readily ignited by a naked flame but providing it iscorrectly installed, this does not present any disadvantage in use.Mechanical PropertiesThe expansion of clay soil is a long-term phenomenon and it is necessary for the compressible fill to react in thesame timescale. Claymaster achieves this by creep deformation, reducing the induced pressures to safe levelsStorageStore Jablite boards under cover, protected from high winds and out and out of direct sunlight. Care should betaken in storage not to bring the boards into contact with highly flammable materials such as paint, solvent orpetroleum products. Smoking should be prohibited in the storage area and the products must not be exposedto flame or other ignition source.THICKNESS OF CLAYMASTER TO COMPLY WITH NHBC REQUIREMENTSSoil heaveUnderside of beamAgainst side of foundations & beamspotentialNHBC void Equivalent NHBC void EquivalentDimension Claymaster dimension ClaymasterHigh 150mm 250mm 35mm 75mmMedium 100mm 175mm 25mm 50mmLow 50mm 100mm 0mm 0mmDesignIn order for Jablite to provide advice on the appropriate thickness of Claymaster for a given situation, thefollowing information is required:1 Maximum expected ground movement (H, mm).2 Acceptable upthrust on the ground- beam foundation (P, kN/m²) as used in the concrete design, or...3 Maximum acceptable lateral thrust on the trench-fill foundation (W, kN/m²); this value should not normallyexceed 40kN/m².The required thickness of Claymaster can be calculated as follows:1 Read-off the value for percentage compressive strain (C, %) given by the maximum load, P or W.2 Calculate the required thickness of material by the equation T = 100 x H/C +10.This value includes an allowance for instantaneous deflection of the Claymaster due to the wet concrete load.Floors | Walls | Roofs Jablite Claymaster Technical Information 5

Claymaster is not designed for use directly below in-situ or suspended ground-floorslabs. The design of beams, foundations and associated details should be in accordance with the requirementsof the NHBC as set out in the relevant Standards.When designing ground beams which will support the weight of the building, care should be taken in areas oflow load, for example under patio doors, to prevent excessive local deflection of the beam. Claymaster must notbe used under groundfloor slabs. Loads exerted by wet concrete for 600mm-deep ground beams will result innegligible compression of the Claymaster.For trench-fill applications, the concrete pour pressure should be limited to 36kN/m² to ensure that excessiveinitial compression does not occur; if necessary, this can be done by reducing the rate of pouring the concrete.Floors | Walls | Roofs Jablite Claymaster Technical Information 6

3 HAZARDS IDENTIFICATIONHuman Health HazardEPS is not known to lead to any skin irritations and is regarded as biologically inert. Residual quantities ofPentane and styrene monomer are insignificant. However during hot wire cutting of EPS if ventilation is notadequate the fumes generated can cause irritation to the respiratory tracts and eyes. Where substantial dustis produced in subsequent processing of EPS (e.g., band sawing or grinding), suitable dust extraction must beprovided, to ensure that exposure does not exceed 10 mg/m³ 8 Hours TWA (Occupational Exposure Limit fortotal inhalable dust).Safety HazardsEPS is organic and therefore combustible. The following fire precautions are recommended:1 Smoking should be prohibited in the storage and processing areas.2 EPS should be stored away from highly flammable material such as paint or petroleum products.3 Storage and working areas should be kept free from rubbish which may spread fire or ignite spontaneously.4 Fire extinguishers and/or hose reels should be available at an easily recognisable fire point and at all timesclose at hand when welding or burning adjacent to EPS.5 Polystyrene dust, like other hydrocarbon based polymers in this form, is classified as a Group (a) flammabledust and precautions should be taken as required by Section 31 of the Factories Act 1961.6 If there is an outbreak of fire, the Fire Brigade should be called immediately and advised that EPS is involved.The area should be evacuated by all personnel, except those fighting the fire.4 FIRST AID MEASURESFirst Aid – Inhalationl Only dust produced from machining EPS or small particles are likely to be inhaled.l Clear the respiratory tractsl If recovery does not occur obtain medical attentionFirst Aid – Skinl No specific measuresFirst Aid – Eyel Flush EPS particles from the eye with waterl If rapid recovery does not occur obtain medical attentionFirst Aid – IngestionNo specific measures.Floors | Walls | Roofs Jablite Claymaster Technical Information 14

If a bigger volume needs to be storedit should be divided into two or more stockpiles at least 20m apart.EPS stockpiles should be sited so that in the event of a fire flowing or dripping molten material will not causethe spread of fire to other combustible materials or to other areas of a building, in particular staircases andcorridors.Storage should be in a level situation at ground level (not on ramps).Floors | Walls | Roofs Jablite Claymaster Technical Information 15

Raised thresholds to doorways or bunds should be provided where storage on upper floors is unavoidable(particularly to the edges of floors without upstands and around staircases).The bund walls should be of fire-resisting and liquid-tight construction.The capacity of the bund area should be at least 3% of the maximum volume of EPS stored.Stockpiles should be sited in such a manner that permanently marked access ways can be maintained.Stockpiles should not impair the performance of any sprinkler system.In warehouses or where large quantities of EPS are stored consideration should be given to the use ofsprinklered premises.On building sites EPS should be stored wherever possible in a fenced compound or building which can besecured, under cover protected from high winds and raised above damp surfaces.
