Suitable for use on concrete pavements and floors;roads, ramps, and runways;concrete basement structures and subways etc.
Isoplaat non-extruding fibreboard is suitable for forming structural expansions joints between in situ ( cast on site) and pre cast concrete structures.
Suitable for forming structural expansion and separation joints in:
• Concrete pavements and floors
• Roads, ramps, and runways
• Pedestrian areas
• Concrete retaining walls and bridges
• Concrete basement structures and subways
• Easy to cut and handle on site
• Will not extrude under compression
• Low cost
• Impregnated wooden fibre board
• Thicknesses 10-25 mm
• Density min 230 kg/m3
• Recovery greater than 70%
• No disintegration in weathering
Store under cover, in the dry. Do not store under wet conditions for long periods of time.
Where to form an expansion joint in in situ concrete, Isoplaat shall be placed against the shuttering on the concreting side before the pour begins. Copper nails may be used to prevent displacement in joints in suspended slabs.
A joint sealing slot can be formed by placing a removable timber former on top of the Isoplaat. Alternatively Isoplaat can be installed to the full depth of the slab and cut back to the required depth subsequently using a power brush
machine. This latter method is generally used for housing estate roads, which cannot be cleaned and sealed until building has finished. Isoplaat should be tamped down to ensure that it fills the joint completely and provides continuous support for the joint sealant.
