Expansion Joint Filler Boards - Bitumenous Boards - Polymers Based Boards

Filler Boards are designed as a standard, Low cost, pre-moulded joint filler for expansion joints in civil engineering and building construction works of all types. The main uses for Bituboard in the construction industry are: roads, bridges, runways, pedestrian areas, basements, retaining walls and site slabs.

Expansion joint filler board is  pre-moulded, closed cell and of cross linked structure. The joint filler must be enough resistance to concrete load as well as must be compressed and recovered during expansion/contraction of the structure/buildings.

The purpose of the expansion of expansion joint is to protect the structure from damage due to temperature changes, whereas the purpose of expansion joint filler board is to fill the gap created by expansion joint or isolation joints to avoid any foreign materials get into the gap. The foreign materials might be non-compressible type and lead to neutralize the purpose of the expansion joint. Hence we must fill the expansion joint gap using any “technical correct” materials. Hope you got the basics of the purpose of expansion joint filler boards.

In large structures or buildings an expansion joint is a construction setup which is designed to absorb up the stresses produced by the increased as well as decreased(heat and cold atmosphere effects) temperatures. The goal is simply to keep the overall installation unscathed and impart the safety.

Generally, large buildings for instance flyovers, stadiums, auditoriums, swim pools etc. have very high consequence of summer time heat which in turn causes to expand the construction materials. By the evening or night the structure goes natural cooling and that goes to normal conditions. As a result, in the long run, that makes it much more in danger of breaks or failures of structures, in the extreme cases.
