Construction and Installation of PERMA-SNOW™

The PERMA-SNOW™ ski carpet is generally manufactured in 2 meter by 2 meter segments that link together to form a total skiing surface of any size required. The segments are laid in a half lap stretcher bond upon the sub-base. The stretcher bond runs down the slope starting off with a full segment on the first line then a half segment on the second line to form the bond. Similarly, half or cut-to-size segments will be used to complete the surface. In every case, the rolled segment should be slowly unrolled downhill to ensure that the meeting point is uniform. If it is not satisfactory, simply detach by peeling from a corner, roll and then relay. The roll must have the loop surface to the inside of the roll and must be unrolled downhill ensuring the attachment tapes secure to each other. If the segment has been fully laid before the dissatisfaction registers the segment must be peeled away from a corner to start the release.


The photo above shows how easily peelable PERMA-SNOW™ truly is.
It is essential to set out the slope with a right angle (90 degrees) before laying the sub-base of Enkadrain (or similar material). The laying of the first line of the sub-base material is critical and must run to the setline. The sub-base should be laid across the first section of the slope being covered and pinned to the ground before starting to lay the PERMA-SNOW™ skiing surface. If the sub-base is well laid to the square the laying of the PERMA-SNOW™ should be simple. It is advisable to use the services of a surveyor for the setting out of the slope.

Although the laying process is simple, we do recommend the use of one of our technical experts when laying for the first time. The day rate for an expert will be provided upon request. All the facility needs to provide is labour and their own working staff supervisor.
