Extrusion
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 tough and maintains its thickness and surface finish under loading and stacking. Due to Bitumen Impregnation it resists absorption of water. This material withstands severe environmental conditions for very long periods of time,
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 concrete slab. Deesa Jolly Board is fabricated to receive dowel bars and the entire joint assembly is placed in position before pouring concrete
