Deesa Duraboard HD 100 is a Cross linked Closed cell Polymer and widely known as compressible Expansion Joint Filler Board. It is flexible as well as has high compression-recovery, therefore suitable for application at places which require readily compressible low load. This filler board is non-tainting and therefore suitable for use in potable water retaining and water excluding structures. It contains no bitumen.
The most compressible filler board for expansion joints Deesa HD100' is a high performance cross-linked, pre-molded, compressible joint filler board. It is readily compressible filler board that ensures low load transfer. ‘Deesa HD100’ (expansion joint filler board) is a non-bituminous superior alternative to bitumen boards.
Duraboard HD 100 - Advantages• Negligible water/moisture absorption
Duraboard HD 100- Description
Dura board® HD insulation is a high-density board product that offers the same high level of dimensional and surface uniformity as Duraboard LD insulation but provides enhanced compressive strength and a higher modulus of rupture. This higher density is achieved through the inclusion of clay additives during the manufacturing process.
Its higher strength makes Duraboard HD insulation particularly well-suited to weight load support applications such as refractory brick backup or for covering larger unsupported spans..
No Weather Effect:
Polyolefin Expansion Joint Filler is resilient and does not distort under low load transfer from wet concrete. No worry, just fit/install and forget. Rain, cold or heat can't change its performance and that makes it more versatile material than others traditionally used filler sheets.
95% recovery after deflection (compression), as it is one of best feature for any Preformed Closed-Cell filler desired
Great Chemical Resistance
As any EJF board needs to be inert to most dilute acids, resistant to oil and hydrocarbons and it is very suitable for EJF applications.
Unlike the bituminous filler board it is very easy to handle and install it. Less handling loss and doesn't get affected by mishandling. Preformed Closed-Cell filler it can be cut in any shape using normal knife. Therefore it doesn't requires any special types of tools or expertise to install them. This makes very useful impact for civil engineers and architects to select in place of the old concept bitumen boards.
These sheets are very versatile to use and are proved to be rot proof and bacteria resistant. This helps to avoid any treatment requirements for blocking such micro-organisms.
Our polymer based joint filler sheets accept nominal temperature cycle with minimal load transfer. Hence it doesn't affect the structure.
Application• Structural expansion joints in concrete brick and block work.
Closed cell structure
Deesa HD100 sheets have extremely low water absorption (<0.05%) property due to closed cell structure and thus none deteriorating and durable too. This feature also helps in better compression recovery.
No bitumen is used and hence it is non staining product which in turn results trouble free for the labor force.
