Duraboard HD 100

Duraboard HD 100 Description

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
• Resilient
• Excellent chemical resistance
• Thermal stability (-400 C to +70p C)
• Non-staining, non-impregnated, non-bleeding
• Environment friendly
• Easy to use – can be cut with knife for easy installation
• Rot-proof and bacteria resistance – no external treatment required before installation

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.


• Structural expansion joints in concrete brick and block work.

• Isolation joints to infill panels.
• Bridge decks, abutments, pier hinge joints, etc.
• Expansion joints in concrete highways, airport runways, taxi tracks, etc.
• Expansion joints in parking areas, industrial flooring etc.
• Water retaining and water excluding structures

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.

Bitumen free

No bitumen is used and hence it is non staining product which in turn results trouble free for the labor force.

Property/Benefits Deesa HD100 Dura Board Bitumen Impregnated Filler Board
Manufactured from Special grade of Polymers Bitumen + Composites + some additives
Product Handling loss NIL Considerable, if not careful
Structure and implications Closed Cell Structure and that will not allow water absorption Not Closed cell structure and that results in very high water absorption
Life Too long Too short
UV stability Yes Not sure
Resistance to Bacterial /Fungal growth Yes No or not sure
Weight Very light Comparatively heavier
Cost to customers In terms of overall cost, very much economical  More due to shorter life. Life is shorter due to Water absorption, non-UV stability, somewhat brittle type nature. 
Product sizes Deesa HD100 boards are available in different sizes to customers to select from: 1200x1800mm, 1500x1600mm, 1000x2000mm & more Traditionally bitumen impregnated board is produced only in one size normally - 1200mm x 1200mm
Stains during applying Never Yes, may be.
Cutting & Installing Deesa HD100 is very easy to install Difficult
Compression recovery > 95% normally. 70% or less
 Overall rating  Excellent product with latest approach in enhancing its properties to meet civil engineering’s requirements. Bituminous joint filler is considered as conventional product and need to rethink to use it for its some drawbacks.
