Macadamite Imparts water resistance, abrasion resistance, wind erosion resistance and strength. An opaque water based emulsion, which, when mixed with soil forms strong aggregates by positioning itself between the granules to form tough, transparent plastic bonds.

Macadamite USES Load bearing, sub-bases for roads, loading zones, floors paths, walk ways etc. Surface coats for roads, parking lots, tennis courts paths walk ways etc. for improved wear water resistance and dust suppression. Embankment, slope and shoulder stabilization against water and wind erosion etc. Macadamite is an emulsion which forms tough plastic bonds with sand or clay soils to provide an excellent firm, dust free, reduced slip, surface or sub-base.

Macadamite Macadamite road bonding or stabilizing compound, when used as a sub-base stabilizer, mixed with the scarified or loosened soil to a suitable depth by spray application, saturating the soil, be it sandy or clay soil, will stabilize, harden and water-proof the soil to the depth that it is applied. This process obviates the necessity for importation of gravel etc. Macadamite can also be sprayed onto the surface of a suitably prepared or shaped gravel or sand road to form a reasonably long-lasting hard and water-proof surface.

Macadamite Macadamite is not influenced by the type of soil it is mixed into or sprayed onto because it alters the plastic index of the aggregates. Macadamite application rates are only about 10% of those of traditional materials so transport costs of the materials to site are dramatically reduced. Macadamite is safe to use and does not leach any solutes into ground water. At low dilutions (1 in 30) Macadamite can safely be sprayed on plants and spill on the skin is easily washed off with water before it dries. Water tankers or other spray equipment should be washed out after use to prevent nozzles and pumps becoming blocked once the plastic dries.

Macadamite A feature of Macadamite is that it can be compared with other products in standard civil engineering tests. At 0,5% on sand, strengths in excess of 1MPa are achieved using the unconfined core technique. Aggregates bonded with Macadamite remain dry. Advantages Can be compared against standards in internationally accepted Civil Engineering tests. Works in sands and clay soils. Aggregates remain dry thus reducing hydration problems. Application rates are approximately 90% less than those of conventional products Environmentally friendly. Easy to use.

Macadamite Application rates SURFACE TREATMENT Mix approximately 12 parts of water to one part of Macadamite Spray onto newly shaped surface at the rate of 0.25 litres Concentrate per square metre or 3 Lt. water concentrate mix per square metre. Apply up to 6 times. (Total volume of concentrate emulsion 0,25 Lt.\M2) Allow to dry. Mix 1 part of Maadamite 2 with 4 parts of water. Spray onto above treated surface at the rate of 0,5 liters of mixture per square meter of surface. Allow to dry (About 1 hour) and repeat once more. Wait approximately 1 hour before trafficking.

Macadamite FULL INCORPORATION Mix up to 20 parts of water with one part of Macadamite. Use 1 to 2 drums of concentrate per 100 Metres of road 7 metres wide.(Approx. 0,75 Lt. concentrate per square Metre of road.) Saturate the newly loosened or scarified soil. Plough the soil over again to ensure proper mixture of the emulsion with the soil. Repeat this process until satisfied that proper saturation has been achieved. Compact. Surface treat compacted road with remainder of emulsion.

Macadamite If no wearing surface is to be applied on top of incorporated compacted road surface, treat as described above. i.e. wait for surface to dry then mix 1 part of Macadamite 2 to 4 parts of water and spray onto surface at the rate of 0,5 liters of mixture per square meter of road. Once dry (About 1 hour) repeat process and allow to dry before trafficking. Cosmo-Dec Everlasting Coatings P O Box 123 Laezonia, 0026 South Africa.
