Underlay grid blocks are universal mounting aids made of polypropylene (PP) for aligning and underlaying elements with a very large installation depth. They are available in a range of thicknesses and allow height compensation that is accurate to the millimetre.
The underlay grid blocks feature a pin system that allows easy stacking and prevents slipping.
Application area:
The surface of the large-sized underlay grid blocks are ideal for underlaying and aligning elements with a very large installation depth such as lift-sliding doors, large window elements, formwork elements, pre-fabricated wood and concrete parts, wooden structures etc.
Field of Application:
Timber construction, element construction, prefabricated house construction, window installation, building construction and civil engineering etc.
Advantages:
Weather resistant and resistant to rotting
Different colour for each thickness
Quick to combine without prior measurement
Pressure load up to eight tonnes
Slip protection by means of stacking pins
Stacking pins disappear under load
Material is physiologically harmless and free of plasticisers
Advice:
When determining the compressive strength, both the load capacity of the block and that of the surface underneath are key.
Not for continuous outdoor use, avoid direct exposure to UV radiation.
