Flexiphalte Maintenance and Repairs

The Flexiphalte system can be expected to provide many years of trouble-free service and is designed to avoid the requirement for regular maintenance as far as possible. However, general vehicle deck maintenance is essential to obtain the maximum performance and ensure the longest life expectancy for the surfacing system; this must be carried out by BriggsAmasco limited every 5 years from Practical Completion of the Project. It should be noted that this inspection regime is integral to the guarantee offer for the project and that any deficiencies must be reported immediately to Briggs Amasco Limited.

During routine maintenance to plant or the building fabric, the Flexiphalte system must be protected against damage caused by high point loadings, spillage of solvents, oil, fuels etc. Where it is necessary to temporarily place heavy plant or equipment directly on the Flexiphalte surfacing, we would recommend the use of 18mm plywood/metal plates as temporary protection. The vehicle deck must not be used as a storage area).

Additional plant, penetrations or fixings that may be required should be referred to and carried out by Briggs Amasco. Any works to the car park must take account of the requirements of any protective finishes, where applicable.

Client Routine Inspections
The Flexiphalte system should be inspected twice yearly, preferably in the spring and autumn, and/or after extremes of weather conditions; a copy of this inspection should be retained by the Facility Manager. It should be noted that as the system is a thermoplastic material, Flexiphalte Paving may be liable to surface marking under vehicle loading during periods of high ambient Temperatures, especially in the early stages of its serviceable life. This is not detrimental to the long term waterproofing and wearing properties of the system. Any deficiencies must be reported immediately to Briggs Amasco Limited.

Inspections should be carried out generally in accordance with BS 6229: 2003 with particular attention to the following items. Reference should also be made to the information contained within the Health and Safety file
for the facility.

  • Check that rainwater outlets are functioning and that gratings are not blocked. Remove debris from the outlets but do not flush silt or dead leave down outlets.
  • Visually check general condition of the exposed Flexiphalte system and report any signs of stressing, creasing/ruckling, mechanical or chemical damaged areas immediately.
  • Check perimeter details and upstand, ensuring that any metal capping, flashings, edge trims and mortar pointing to chase details are secure
  • Check all flexible seals and expansion joints for obvious damage and deterioration; this should extend to cover flashings and the like.
  • Visually check upstand flashings to plant support legs/upstands.
  • Visually check upstands and flashings to pipe penetrations.
  • Visually check all mastic seals and repair/replace as necessary.
  • Visually check all line markings.
  • Visually check the condition of any solar reflective paint or proprietary coating. It should be noted that are-coating programme will be required in accordance with the manufacturer’s instructions.
  • Check other building components e.g. barriers, balustrades, flashings, parapet walls etc. for defects.

The agreed maximum premium for each Flexiphalte System Inspection is set at £1,500.00; this will include inspection, written report and any works carried out at the time of inspection up to a maximum of 4 hrs maintenance work.
The cost of inspection and maintenance will increased after the first inspection in line with the RPI published by the ONS.

A written record of all inspections will be filed by Briggs Amasco and a copy passed to the facility manager for retention.

  • Visually check the condition of the Flexiphalte wearing course including damage or deterioration.
  • Visually check the condition of the Flexiphalte upstands and abutment details including flashings, pointing and sealants etc.
  • Visually check the condition of the Flexiphalte details such as outlets, gutters, penetrations and collars.
  • Visually check the security of all ancillary components and fixtures where they penetrate the Flexiphalte.
  • Visually check the condition of all flexible seals.
  • Visually check the condition of expansion joints.
  • Visually check the underside of the slab where practicable for signs of water ingress.
  • Visually check and comment on the condition of line markings and surface protection.

Accidental Damage
In the event of accidental damage occurring to the Flexiphalte system, Briggs Amasco should be notified immediately in order that a practicable solution to the problem can be agreed and any remedial actions taken. Failure to make contact with Briggs Amasco could invalidate any guarantee offered.

Flexiphalte Repairs
Flexiphalte vehicle decks which are under guarantee should only be repaired by Briggs Amasco, with design reference to Technical Services.

Flexiphalte car park waterproofing and surfacing systems are resistant to common de-icing materials including rock salt, Calcium Chloride Flakes and Prilled Urea. It should be noted that the use of metal face plows and loaders to remove snow and ice will damage the surface of the Flexiphalte.

Should the deck require cleaning, we recommend the following methods;

  • Manually brush away any loose particles, general dust, dirt etc. Ensure all outlets, drainage points, gutters and downspouts are clear and free from any blockage. Apply a cold or warm water pressure wash with an approved detergent in solution; rinse the surface with clean, cold water on completion.
  • The head of the water lance should be kept at least 500mm away from the Flexiphalte surface at all times
    and the pressure should be restricted to less than 1,500psi.
