Before using screws to fix, make sure that the installation gap is kept according to the suggested installation temperature in the length and width direction for PearlSnow and PearlSlide, reference on the above chart. The attaching and fixing tool is different according to different sub-base material. Compact Soil base:

On the compact soil base, use 30cm length screw pins to fix, normally every 1m or 1.5m or 3m use 1 pin, depending on the sub base compact level and contour.
For PearlSnow and PearlSlide, there is an additional option of Velcro hooks attach on the edge, so it is convenient to attach PearlSnow to the geo-non woven fabric before using the screw pins.
For the PearlTile, if the soil ground is not so flattened, use a 1.1m length, 40cm width wooden board to lay under the PearlTile interlocking position, so the tile can interlock on the flattened and stiff surface, then use 30cm length screw pins to fix to the soil ground. Wooden base:

Wooden base also needs to lay the waterproof membrane to handle the water drainage and needs to take care to leave the gap between the wooden sheet to prevent shrinkage and expansion problems.
After that, lay on the geo-non woven fabric, then use the tapping screw length 30 mm to fix on the wooden base.

Screw pins for compact soil ground Metal board base: Metal board base also needs to lay the waterproof membrane to handle the water drainage. After that, lay on the geo-non woven fabric, then use the drilling tail tapping screw length 30 mm to fix on the metal board base. Cement base:

For cement base, also needs to lay the waterproof membrane to handle the water drainage.
Lay down the geogrid nonwoven and install the DreamSnow, PearlSnow or PearlSlide on top with plugs and screws (5 cm long) at least 10 pc/m².
