FAQ's of Expansion joint filler board:
Q: How should the expansion joint filler board be installed in concrete constructions?
A: To install the expansion joint filler board, position it flush between adjacent concrete slabs prior to pouring. Ensure proper alignment and secure the board in place. The process helps maintain gap consistency for optimal thermal expansion and contraction.
Q: What are the key benefits of using this expansion joint filler board?
A: Key benefits include excellent compression recovery (over 90%), good resistance to water and ageing, low heat conductivity, and durability against rot. Its flexible and compressible nature helps it absorb movement, preventing cracks and structural damage.
Q: When is it recommended to use the expansion joint filler board?
A: This filler board is recommended during construction or renovation of concrete pavements, bridges, buildings, and roads where movement from thermal expansion and contraction is anticipated. Early installation during slab placement is advised for optimal performance.
Q: Where can the expansion joint filler board be applied effectively?
A: It is ideal for use in structural expansion joints in building foundations, concrete slabs, bridges, highways, airfields, and industrial floor joints-essentially wherever accommodating expansion and contraction is critical.
Q: What is the shelf life and how should the product be stored?
A: The expansion joint filler board offers a minimum shelf life of 12 months when stored under recommended conditions. Keep the boards packed on pallets, away from moisture and direct sunlight to maintain their properties.
Q: What makes this expansion joint filler board suitable for harsh environments?
A: Its bitumen-impregnated fibreboard composition, combined with excellent weather resistance, low water absorption, and high compression recovery, ensures that it withstands harsh conditions, including temperature fluctuations and exposure to moisture.
Q: Can the expansion joint filler board be supplied in custom sizes and thicknesses?
A: Yes, in addition to standard 2440 mm x 1220 mm sheets, custom widths (100-1200 mm) and thicknesses (10, 12, 18, 25 mm or as needed) are available to meet specific project requirements.
