Expansion
Joints Boards is the most suitable as
a shock absorber in the joint slabs
of bridges, decks, roads, runway etc.
Where the casting of concrete is in
slab form wherein sufficient provision
for the accomodation of expansion &
contraction is adhere to which occurs
due to periodical changes in temperature.
In India & neighbouring countries
where the effects of extreme climatic
conditions are considerable, EM BEE
BOARD (EXPANSION JOINTS BOARDS - Bitumen
Impregnated Fibre Joint Filler Board-Generally
confirms IS-1838) is of prime importance
as it is an effective & suitable
absorber of contraction & expansion(joint
filter) by which it will preserve the
life & everness of the surface.
For runway & road construction the
normal practice is to provide transverse
& longitudinal expansion joint of
12 mm, 18 mm & 25 mm thick (depending
on lenght of adjustment slabs) i.e.
between butting slabs of reinforced
concrete at designed intervals, and
at intersactions with other constructions
i.e. level crossings, bridges etc. |

| EM
BEE EXJO BOARD( EXPANSION JOINTS BOARDS ) is available
in the following sizes: |
| 2'
X 4' and 4' X 4' in 12 mm / 18 mm / 25 mm thickness
(Also higher thickness may be made against the requirements. |

| TECHNICAL
ASPECTS OF EXPANSION JOINTS BOARDS |
| The
expansion joints between the slabs fulfill the following
functions : |
| |
| a) |
Expansion Joints Boards
forms a resilient and adhesive barrier in
concrete joints, capable of resisting the
infiltration of water & the ingress of
solid particles. |
| |
|
| b) |
Facilitate unhindered movement
of concrete slabs in expansion & contraction
by resisting entry of foreign matter in joint
space. |
| |
|
| c) |
Methodical & fault-free
installation at constraction site for optimum
effect. |
| |
|
|
| EM
BEE EXJO BOARD( EXPANSION JOINTS BOARDS (Bitumen
Impregnated Fibre Joint Filler Board-Generally confirms
IS-1838)) is
therefore manufactured out of compressible, resilient
& non extrudible materials for durability &
longevity. |
