Product Description
Formerly: SIL seal / Back-up Rods
Bonding for assuredstrength with DURArods
DURArods is a closed cell polymer based foam filler material with a circular profile. Itensures stronger bonding of sealant with masonry, aluminium or other substrates& helps to maintain desired thickness of sealant at the joints centre. Itdoes not bond with cold applied sealants. DURArods (back-up rods) is used as back-up to sealants toexpansion joints and structural glazing systems.
Features :
- Closed cell hence negligible water/ water vapour absorption
- Excellent chemical resistance - Inert to most acids and alkalis
- Cost effective space filler
- Allows unrestrained expansion and contraction of sealants. Eliminates bubbling of sealants
- Non-staining
Applications :
- Pre-cast panel joints
- Coping joins
- Contraction joints
- Expansion joints
- Back-up to sealants in structural glazing systems
- Glazing joints
- Isolation joints
- Dynamic joints in masonry
- Window and Door frame perimeters
- Control joints

Durable, Water Resistant Construction SolutionThis expansion joint filler rod stands out for its smooth, closed-cell structure, providing dependable water resistance and compressibility. Its non-bituminous nature and medium load-bearing capacity ensure lasting performance in concrete pavements, bridges, and building joints. High-quality XLPE foam resists chemicals, UV exposure, and extreme temperatures, making it suitable for Indias varied climates.
Simple and Versatile InstallationSupreme Non Bituminous Expansion Joint Filler Rod is straightforward to install using a convenient push-fit methodno adhesive required. Offered in standard diameters from 6 mm to 50 mm and customizable lengths, it adapts to a wide range of project requirements. It is compatible with manual or automatic fitting processes, streamlining on-site application for new builds or repairs.
FAQs of Supreme Non Bituminous Expansion Joint Filler Rod:
Q: How is Supreme Non Bituminous Expansion Joint Filler Rod installed in concrete joints?
A: The filler rod is simply push-fitted into the joint gap. Thanks to its closed-cell structure and compressibility, it conforms easily within the joint, requiring no adhesive. It is suitable for both manual and automatic installation methods.
Q: What are the main benefits of using this non bituminous expansion joint filler rod?
A: Key advantages include excellent water resistance (<1% absorption), chemical inertness, high compression recovery (>90%), UV resistance, and adaptability to extreme temperatures. Its eco-friendly XLPE foam is non-toxic, recyclable, and durable, making it an ideal, long-lasting solution for construction joints.
Q: Where can this expansion joint filler rod be effectively used?
A: It is designed for construction expansion joints in concrete pavements, bridges, buildings, and other civil engineering projects. It supports medium load-bearing applications and is available in customizable thicknesses and diameters to meet diverse on-site requirements.
Q: What is the typical process for selecting the correct size and grade of rod?
A: Select the diameter and thickness based on the expansion joint width and design specifications. Standard sizes range from 6 mm to 50 mm diameter, with options for custom lengths and optional fire-retardant grades for enhanced safety in specific environments.
Q: When should this expansion joint filler rod be used during construction?
A: The rod is installed before pouring sealant, after forming the expansion gap in concrete structures. Its use helps establish a firm backer for sealants, controls sealant depth, and enables flexible movement within the joint even after curing.
Q: Why is the non bituminous, closed-cell structure important for this product?
A: A non bituminous, closed-cell finish prevents water ingress and resists most chemicals, reducing the risk of joint deterioration. This structure also improves compression recovery and durability, ensuring long-lasting joint integrity with minimal maintenance.
