Cork Fillerboard is manufactured to expand according to the ASTM D1752 Type III specification and is manufactured from the bark of the cork oak tree and granulated to be compressed into blocks then cut into sizes to suit your requirements on site.

Cork Fillerboard, being a natural based product has the ability to withstand a variety of environmental and climatic conditions. As concrete expands and contracts during daily climate and temperature changes, S.E.C Cork Fillerboard automatically adapts to the conditions and prevents your concrete from bursting or cracking.

Self Expanding Cork is available in 10mm, 12mm, 15mm, 20mm & 25mm thick sheets. Please contact our friendly staff to check stock availability of your chosen size of self expanding cork fillerboard.
