Chamfer & Void Former

 

SCP offer an advisory/design service to specifiers on the use and application for all our Waterproofing Systems. Our national team of Technical Sales Engineers are available to liaise with site personnel to discuss and advise on your specific requirements.

The SCP range of crack inducers are specially designed profiles to form stress relief joints in concrete slabs laid using the long strip system of paving.

  • Crack Inducers
  • Base CrackInducers
  • Expansion Joint Seals
  • Isolation Joint Seal

Clearcrack* Crack Inducer/Joint Former

Clearcrack, manufactured from Heavy Duty P.V.C., is designed for use where the top section of the crack inducer is to be left in-situ in the floor to form a wearing surface.

Sizes:

Depths Length Width at Surface
40.0mm 5.0 metres 10mm
50.0mm 5.0 metres 10mm
75.0mm 5.0 metres 10mm
  • Manufactured from high impact PVC.
  • Eliminates use of bottom crack inducers on slabs with a depth of less than 300mm.
  • Rigid PVC joint former with integral tear-off top that gives an instant joint void.
  • Top portion can be left intact omitting need for joint sealant.
  • Void size 25mm deep, 10mm wide in all sizes.
  • Inserted into wet concrete when finished level achieved reduces risk of random cracking.
  • For controlled crack inducement and joint forming in concrete paved areas.
  • Clearcrack* should be between 1⁄4 and 1⁄3 depth of slab.

Two-part Crack Inducer/Joint Former

The two-part crack inducer is designed for use where the top section is removed to expose a sealant void which is sealed with SCP Compression Seal or Sealant.

Sizes:

Depths Length Width at Surface
50.0mm 5.0 metres 10mm
75.0mm 5.0 metres 10mm
50.0mm 5.0 metres 13mm
75.0mm 5.0 metres 13mm
125mm 5.0 metres 10mm
125mm 5.0 metres 13mm
  • For controlled crack inducement and joint forming in concrete paved areas.
  • Inserted into wet concrete when finished level achieved reduces risk of random cracking.
  • Void size 25mm deep by width as indicated above.
  • Top section easily removed prior to sealing.
  • Eliminates use of bottom crack inducers on slabs with a depth of less than 300mm.
  • The two-part crack inducer should be between 1⁄4 and 1⁄3 depth of slab.

Description

SCP base crack inducers (Bottom 'Y' type) are for use under concrete slabs in conjunction with SCP Clearcrack* to form stress relief joints in slabs over 300mm thick.

Sizes

Depth Length Width at Base
40.0mm 5.0 metres 60.0mm
75.0mm 5.0 metres 80.0mm

Dowel Bar Sleeves

Dowel bar debonding sleeves are manufactured from a high grade flexible pvc and are designed to form a positive debonded dowelled joint in reinforced concrete construction. The use of Dowel Bar Sleeves overcomes the problems associated with paint on compounds, tapes, greases, etc. Sleeves are supplied complete with compressible foam filler plug to accommodate joint movement in expansion joints.

Sizes

Bar Dia. Sleeve Length Nominal Wall Thickness
12mm 450mm 1.00mm
16mm 300mm 1.00mm
20mm 300mm 1.00mm
25mm 300mm 1.00mm
32mm 375mm 1.00mm

Other sizes available to special order, depending on quantity required.

  • Unique design allows for easy installation, but difficult removal.
  • Grip fins provide mechanical anchorage increasing retention properties.
    Can be used in conjunction with SCP concrete/rubber adhesive for increased performance.
  • Easily installed Does not require skilled labour or specialist equipment - simply inserted into preformed void.
  • Can be fixed in damp conditions as no priming is required.
  • Same section used vertically and horizontally simplifies ordering. Supplied preformed in 25 metre coils. Eliminates site mixing normally associated with wet sealants.
  • Neatly contained within void. Does not spread or extrude during use.
  • Successfully tested to 30ft. head of water for use in water excluding structures.
  • Manufactured from neoprene to a tough robust design with ozone, ultra violet, oil and chemical resistant properties.

Specification Compliance

SCP expansion joint seal conforms to the requirements of ASTM 2628.

Size

Supplied in 25 metre coils to suit the following joint widths:-

Product Description

Installation Joint width mm

Actual Seal
width (mm) x depth
Min Max
20mm Seal 18 23 28 x 25
25mm Seal 23 28 32 x 25

  • Unique design improves appearance of movement joint detail where slab abutts wall, whilst providing an effective seal.
  • Easily installed into preformed void above joint fillerboard without the need for specialist labour or equipment.
  • When used in conjunction with Expansionthene* foam fillerboard, with rip-off top, installation is accelerated.
  • Grip fins provide mechanical anchorage, increasing retention properties.
  • Can be installed in damp conditions as no priming required.
  • Manufactured from rubber to a tough robust design with resistance to attack from weathering, ultra violet light, ozone and oil spillage.

Supplied in 25 metre coils to suit void 20mm x 20mm
