BITUMEN MASTIC PADS

Expansion Joint Filler Board :

Deesawala Industries are leading manufacturers and deals with Deesa Jolly Expansion Joint Filler Board, which is made from cane fiber. Our high quality mastic pads are the best in the industry. Infused with Bitumen in various percentages, our pads are perfect based material for expansion joint fillers. Based on U.K, U.S.A, and Indian standards, we manufacture Expansion Joint Filler Board.

Deesa Jolly Board Expansion Joint Filler:

Being the leading Bitumen Mastic Pads manufacturer, we offer Deesa Jolly Expansion Joint Filler Board which is environment-friendly, high performance, water-resistant, bitumen impregnated, and processed from cane fiber. There are available in different sizes and show efficient resistance to compression, with outstanding recovery characteristics. Our Bitumen Mastic Pads are specially designed to be used as expansion joint filler in concrete, brick, block work, and isolation joints.

It is a pre-molded, high performance joint filler board. It is a closed cell and of cross Linked structure. It has an excellent recovery of 95% (after compression upto 50%), which makes it the most suitable product for this application. It is an exclusive product specially designed to be used as expansion joint filler in concrete, brick, block work and isolation joints.

  • Uses
  • Roofs & floor finishes: Ideal for filling expansion joints in concrete floors.

    External wall cladding: Filling structural expansion & structural separation joints in block & in-situ concrete construction.

    Internal surfaces: Filling expansion joints across concrete floors, including screed floors with underfloor heating.

    Traffic surfaces: Filling expansion joints in motorways, roads, runways, pedestrian areas, bridges, curbs etc.

    Reinforced concrete structures: Expansion joint fillers in piers and lateral supports like abutments.

    Building superstructures: Filling expansion joints in basements, retaining walls, site slabs, subways & other water excluding structures.

    Mastic Pads Advantages

    • Easy to cut, handle, and install.
    • Closed cell structure resulting in negligible water/moisture absorption.
    • Use of ShaliBar/Backer rod is optional.
    • Excellent recovery after compression.
    • High resistance to chemicals like most acids, alkalies oil and hydrocarbon.
    • Rot proof hence does not age and disintegrate over prolonged use.
    • Bitumen free hence non-staining and free from bleeding.
    Mastic Pads

    Mastic Pad Application

    • Expansion joint filler strips in all concrete traffic surfaces like highways, airports, runways and streets.
    • Expansion joint fillers in reinforced concrete structures like piers, retaining walls, and lateral supports like abutments.
    • Expansion joint fillers in driveways, aprons, pavements, curbs, gutters and other concrete paving work.
    • Expansion joint fillers are used against existing or between adjacent constructions and insets in concrete paving like drains, manholes, etc.
    • Various other internal finishes, flat works and concrete floors according to the state of the art and local regulations.

    Extrusion

    Deesa Jolly Board when compressed to 50% of its thickness with 3 edges restrained, it shows an extrusion of not more than 1 to 2mm on its free edge.

    (Permitted: less than or equal to 6.4mm)

    Compression

    Deesa Jolly Board when initially subjected to a load between 689 to 5171 kPa (and 100 to 750 PSi) in order to compress it by 50% of its original thickness, it shows a loss of not more than 0.1 to 0.2 % by weight.

    (Permitted: less than or equal to 3% by weight).

    Durability & Handling

    Deesa Jolly Board is durable and holds thickness and surface finish under loading and stacking. As it is Bitumen Impregnation, it doesn’t absorb water. This material can withstand any environmental changes, resulting in longevity. 

    Deesa Jolly Board is brought flush with the concrete slab and extends full depth of the slab, placed approximately ¾ of an inch below the surface of the concrete slab. A suitable sealant is applied either at the top or bottom of the slab to close the joint against hydrostatic pressure. The dowel bar is used to preserve alignment of adjacent sections of the concrete slab. Deesa Jolly Board is fabricated to receive dowel bars and the entire joint assembly is placed in position before pouring concrete.
