Standard product features

Material:

Manufactured by mixing asphaltic cement and limestone fine and coarse aggregates using conventional mixing techniques. The asphaltic cement consists of a polymer-modified bitumen.

Bay jointing:

Splayed steel gauges must be used to ensure correct thickness of IKO Permapark Paving according to the selected specification and to provide an increased bonding edge between adjacent bays of IKO Permapark Paving. Normal bay jointing techniques of warming and cleaning the edge of the previously laid area must be carried out to ensure fusion between the bays.

Margin infill to abutments:

The IKO Permapark Paving should terminate approximately 100 mm from abutments and the margin infilled with IKO Permapark Waterproofing. A second angle fillet is then formed at the base of the skirting roof to complete the detail.

Surface finish:

The IKO Permapark Paving layer should be well rubbed with clean, sharp sand during final floating of the hot asphalt. In addition, a dimpled surface may be achieved using a crimping roller.

Pre-coated chippings must be rolled into the surface where the anticipated gross vehicle weight exceeds 7.5 tonnes, to improve resistance to indentation, and in this case IKO Permapark Paving would not be sand rubbed. However an uneven scatter of chippings must be accepted making this finish less attractive than the alternatives.

For normal car park usage IKO Permapark does not require protection against minor oil, petrol or grease contamination but prolonged contact may cause localised softening of the binder. Coatings are available for high risk areas or where a coloured finish is required.

Car and light commercial vehicle ramps:

Ramps should be cross tamped and lightly primed with IKOpro High Bond Primer. To prevent undue thinning of the IKO Permapark Waterproofing, tamps should not exceed 5 mm in height. Nominal 25 mm thick single coat IKO Permapark Paving with crimped finish on nominal 15 mm thick single coat IKO Permapark Waterproofing. Where ramps are subject to HGV traffic, the thickness of the IKO Permapark Paving should be increased to 40 mm with a crimped finish. In situations where warming elements are required, these should be embedded in a sand/ cement screed beneath the IKO Permapark.

Expansion joints:

Where the design calls for a controlled gap in the structural slab, an expansion jointing system must be included through the finishings.

Detailing:

In the case of concrete, brickwork and similar substrates, a two coat IKO Permapark Waterproofing skirting is applied to all upstands to a nominal thickness of 13 mm, and a minimum height of 150 mm. A two-coat angle fillet should be formed at the junction of the vertical and horizontal waterproofing. The top of the skirting is splayed and turned into a 25 x 25 mm chase unless the waterproofing continues horizontally. In certain circumstances, differential movement between the parapet and structural deck must be catered for by the provision of a free-standing upstand and cover flashing.

Product Options

Specification:

- Economy specification PA3:

  • Internal levels only, 3.5 tonnes maximum gross vehicle weight.
  • Comprises a nominal 25 mm or 30 mm thick single coat of IKO Permapark Paving. For installation on IKO Glass Fibre Tissue separating membrane, loose laid with minimum 50 mm side and end laps. The IKO Permapark Paving bay joints to be positioned centrally over a nominal 300 mm wide x 10 mm thick IKO Permapark Waterproofing straps.

- Insulated service deck specification PA6 (with pre-coated chippings):

  • 44 tonnes maximum gross vehicle weight and 11.5 tonnes maximum individual axle loading.
  • Comprises a nominal 40 mm thick single coat of IKO Permapark Paving on a nominal 20 mm thick two-coat IKO Permapark Waterproofing. For installation on IKO Glass Fibre Tissue separating membrane, loose laid with minimum 50 mm side and end laps on minimum 100 mm thick Lytag Grade 20 concrete slab, reinforced with 142 steel wire mesh at mid height.
  • If the anticipated gross vehicle weights are likely to exceed 7.5 tonnes, 14 mm or 20 mm pre-coated chippings must be rolled into the surface, at the rate of 7.5–10 kg/m² and 10–13 kg/m² respectively, to improve indentation resistance. The thickness and grade of extruded polystyrene insulation must be in accordance with the manufacturer's recommendations based on imposed loading and required U-value.
