Pro-Bed HS Bulk: Bedding Mortar

Application

  • The product provides a perfect bound base for natural stone paving and cobbles, concrete paving, flags and block paving, which once laid with UltraScape Pro-Bed HS ECO are able to accept foot traffic after just 12 hours and vehicular traffic after 24 hours.
  • The material is also not subject to environmental erosion, which can lead to increased point loads on slabs and consequent breakage.

Description

UltraScape Pro-Bed HS is formulated from selected cements and graded fillers. The pre-blended fine bedding concrete is supplied in 25 kg bags or alternatively, for those large projects, in 30 tonne bulk silos. The product can be laid from 10–75 mm in one pass with greater depths achievable using successive layers. The material mixes easily on-site with the addition of water and provides a compressive strength of 38 N/mm² after 28 days complying fully with BS 7533. This material should not be used in temperatures below 5°C.


Features and benefits:

  • Can be laid from 10–75 mm in one pass.

  • BS 7533 compliant.
  • Small contractor friendly units.
  • Bulk silos for larger projects.
  • Pre-blended - just add water.
  • Open to pedestrian traffic in 12 hours.
  • Open to vehicular traffic in 24 hours.
  • Long-term durability.
