Cemwood
Cemwood
Cemwood comprises super lightweight wood chips that, through a patented manufacturing process, are mineralised using a high quality hydraulic binder. The effect of this is that surface of the wood chips and the texture within the wood grain are coated with a strengthening and preserving calcium silicate hydrate layer.
The characteristics of Cemwood as a natural material are enhanced through the mineralisation process, in particular Cemwood’s mechanical binding properties, durability, behaviour in fire and resilience. Cemwood is 100% fire retardant and is thus classified Bfl-s1 (EN 13501) – no mean feat for what is, at its core, a natural timber product.
As Stable and Secure as a Hydraulically Bound Fill
When load is applied to Cemwood, the combination of its woodchip grain and the mechanical properties imparted to it by the mineralisation process provide exceptional stability. The natural timber grain provides a comparatively large amount of surface area, and the calcium silicate coating provides a great degree of slip resistance. This keeps adjacent Cemwood chips robustly interlocked with each other at a minimum thickness of only 10 mm.
The mineralisation process also completely supresses water absorption – the swelling and shrinkage that is characteristic of wood products is non-existent. Cemwood is also completely resistant to fungal growth, rodents, insect infestation and rot.

One cubic metre of Cemwood dry levelling product binds 95 kg of CO₂ This is the equivalent to a gas volume of 50,000 litres of CO₂.

Datasheet
Cemwood:
Establish a reference datum and the required height of levelling compound.
01
Distribute levelling compound to the average height required and in lines to suit the width of the levelling guides.
02
Smooth the slate in the corners and in the parallel strips to the desired height using a smooth-edged trowel.
03
04
Fill in the area between the parallel guides with further granules and then place the levelling rule on the parallel guides.
05
Draw surplus slate granules into the empty area using the levelling rule.
06
In larger rooms, installation is simplified by the use of further parallel guides.
07
After the levelling guides have been removed, ensure that the slate that formed their base is made level with the rest of the floor.
08
Insulation panels should be used to walk on the levelling compound. The granules will not be displaced from their level when observing this. Once a uniform load is applied to the slate, it will mechanically bind together.
