Technical
UltraScape Perma Bed is formulated from selected cements and graded fillers. UltraScape Perma Bed is supplied pre-blended in 25kg bags. The product can be laid from 10mm to 100mm 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 >35N/mm2 after 28 days complying fully with BS 7533.
UltraScape Perma Bed is fully permeable and is frost resistant. The free passage of water through the cured matrix of the product ensures that correctly laid paving should not suffer from reflective staining emanating from the underside of the paving elements.
This material along with most standard setting cementitious products should not be used in temperatures below 5°C*.
(* Ultrascape bedding mortars can be used below 5°C, only if the following conditions are met.
- a) The ground to be laid upon is not frozen.
- b) The temperature is 2°C and rising.
- c) The product must be protected from frost.)
Preparation
It is of vital importance that the supporting layer that is to receive UltraScape Perma Bed is stable and not liable to settlement or heave. Supporting structures must be cleaned, pre-soaked and all ponded water must be removed prior to application. To promote bond, the supporting layer can be primed using UltraScape pro-prime slurry primer. Please note that this product is suitable only for bound/rigid construction, not for unbound/flexible applications.
Mixing
Add 1.75 litres of clean water to a suitable mixing vessel. Slowly add the contents of one 25kg bag. Mix mechanically for a minimum of 3 minutes and a maximum of 5 minutes. Do not add extra water or part mix bags.
