Our range of Expansion Joint Filler is manufactured from water resistant, bitumen impregnated, Softboards. It is available in a wide range of sizes, both as boards & strips in thicknesses of 12mm, 18mm & 25mm. Available in sizes 1220mm X 610mm even other sizes on special request.

Expansion Joint Filler displays excellent resistance to compression, with outstanding recovery characteristics. The fillers are environment friendly as opposed to the environment destroying thermocole/plastic expansion joint filler.

Applications:

• External wall cladding: Filling structural expansion & structural separation joints in block & concrete structures.
• Traffic surfaces: Filling expansion joints in roads, runways, pedestrian areas, bridges etc.
• Roofs & floor finishes: I deal for filling expansion joints in concrete floors.
• Building superstructures: Filling expansion joints in basements, retaining walls, site slabs, subways & other water excluding structures.
