PROMATECT®-H Upgraded concrete/brick wall option 1

Upgraded to 120 or 240 minute fire resistance in accordance with the requirements of BS 476: Parts 21 and 22: 1987 and/or AS 1530: Part 4: 2005
  1. PROMATECT®-H board fixed directly to one or both sides of the concrete/brick walls
  2. M6 masonry anchors with 16mm steel washers, minimum anchor length should allow for 25mm penetration into the concrete, fixed at 500mm centres
  3. Caulk all perimeter gaps with PROMASEAL®-A Acrylic Sealant
  4. Concrete/brick walls

For loadbearing upgrading, the concrete cover to the reinforcing at the non board side must be of minimum 30mm thick and minimum 50mm thick for 120 minute and 240 minute fi re resistant wall respectively

The board thickness of the protection material is relevant to the strength of the concrete and the cover to the reinforcement. In some instances, e.g. for high strength (Grade B70) condition, PROMATECT®-H 50mm thick is required for 120 minute fi re resistance performance tested to RWS fire curve. This applies to all exposure curves
