Ultrascape Pro-Bed HS fine bedding concrete is specifically formulated to meet and exceed the strict demands of BS 7533. The product provides a perfect bound base for natural stone paving, cobbles, concrete paving, flags and block paving which, once laid are able to accept foot traffic after just 12 hours and vehicular traffic after 24 hours. The material is also not subjected to environmental erosion, which can lead to increased point loads on slabs and consequential breakage.

Formulated from selected cements and graded fillers. The pre-blended fine bedding concrete is supplied in 25 kg bags or alternatively for large projects in 30 tonne bulk silos and bulk bags.

The material mixes quickly 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. To promote bond, the supporting layer can be primed using Ultrascape Pro-Prime slurry primer. Please note that this product is suitable for bound or rigid construction, not for unbound of flexible applications.

Features and benefits:

  • Can be laid from 10–75 mm in one pass with greater thicknesses achievable using successive layers.
  • Shrinkage compensated.
  • Long-term durability.
