Flexi-Range - Joint & Crack Treatments

 

Our “Flexi-Range” systems include:

  • Flexi-Seal - Saw Cut/Seal
  • Flexi-Band - Fibre Reinforced Band
  • Flexi-Screed - Fibre Reinforced Inlaid/Recess Repair
  • Flexi-Joint - Full Depth Repair (Highway Agency Approved System)

 

These products range from the cost effective blow out and seal overband sealing to the saw cut or planed out inlaid reflective crack treatment all of which have been extensively used.

 

Our ‘Flexi-Range’ products have been based on the proven ‘Flexi-Joint’ system combining techniques and specifications which have out performed other reflective crack treatments in the market place. The sealant is a specially blended polymer modified bituminous screed system incorporating SBS polymers, selected bitumens, process oils and extenders. Combining a uniform distribution of chopped fibres and aggregates the Flexi-Range products provide a stable and effective treatment to reflective cracking with improved elastomeric performance for easy and rapid application.

 

‘Flexi-Range’ provides various reflective crack treatments to be chosen depending on the surface condition and locality. Once sealed further deterioration above or below the surface interlayers will be prevented subsequently reducing any further reflective cracks.

 

All of our ‘Flexi-Range’ systems can be dressed with an aggregate finish, to produce a durable, non-reflective, high SRV finish, various colours can be chosen to blend with the original surface course if required.

 

 

 

Flexi-Band: Standard (PSV 55) Super (PSV 70)

 

A simple effective method of sealing multiple joints or cracks in asphalt or concrete.

 

Preparation with the hot compressed air lance system cleans and dries the area, the Polymer Modified binder compound is then applied by screed box. Combining a uniform distribution of chopped fibres and aggregates the Flexi-Band product provides a stable and effective treatment to reflective cracking, with improved elastomeric performance for easy and rapid application.
 

 

 

 

 

 

 

Flexi-Seal – Saw Cut & Seal

 

Cracks are cut out with a diamond abrasive saw to leave a uniform channel, typically 12mm wide and 20mm deep. This is cleaned and dried with a hot air lance and sealed flush ± 3mm with the existing road surface using the sealant. The joint material lays in the wearing course, not merely on the surface, ensuring long term durability.
 

 

 

 

 

 

 

Flexi-Screed

 

Where damage is too severe for treatment by Flexi-Band alone, the surface is mechanically planed out to the width agreed with the client and to a depth of up to 20mm, to ensure a stable base and boundaries for the filling. Cleaning and drying with the hot air lance system is followed by the application of the Polymer Modified sealant. Surface finish is lightly rolled hot aggregate dressing that provides a long lasting repair with non-reflective appearance and high skid resistance.
 

 

 

 

 

 

 

 

Flexi-Joint

 

For repairs of greater depth, the versatile Flexi-Joint system adds stability. After excavation, the surfaces are cleaned and dried, a bitumen impregnated glass fibre gauze underlay is then put in place. The filler is aggregate, thoroughly cleaned, heated and coated with the Polymer Modified sealant and compacted by a roller. A coating of binder is then screeded across the area to provide a watertight seal, and surface dressed with a durable, non-reflective, high skid resistant hot aggregate.
