Introduction to road heating steps

Installation steps

  1. STEP 1

    Cut concrete bed

    First a 9mm wide x 7cm deep groove is cut into the concrete using a concrete cutter.
  2. STEP 2

    Curing

    The area around the cut is first cured so that only the cut area is affected.
  3. STEP 3

    Insert thermal sheet and connect to electrical lines

    Once preparations are complete, the thermal sheet is laid and connected to the electrical lines.
  4. STEP 4

    Fill with sealant

    Next, it is filled with a sealant so that the TAIYO SHEET is completely waterproofed.
  5. STEP 5

    Remove curing and clean up

    The pumice sand is swept away after the curing is removed to finish the job.

Results of road heating
After road heating work was completed, 60cm of snow were on the road 24 hours later. The area of the road with TAIYO SHEET removed 60cm of snow on either side (right/left) of the sheet for a total of 120cm area.

Testing on the Tokyo Expressway

We tested TAIYO SHEET on a maintenance road of the Tokyo Expressway. It is verified that TAIYO SHEET reduced installation time and sped up the work, as well as provided adequate heating effect.
