Concrete Expansion Joint Filler Board Road Construction

Product Description

Sure! Here's a clear and practical breakdown of the Expansion Joint Filler Board used in road construction:

Expansion Joint Filler Board for Road Construction

What Is It?

An Expansion Joint Filler Board is a compressible, pre-formed board installed between concrete slabs in roads and pavements to:

• Absorb expansion and contraction of concrete

• Prevent cracking, buckling, or blowouts

• Maintain joint shape and function over time

Standard Specifications

Common Material Types

1. Bitumen Impregnated Fiber Board (BIFB) Most common

   • Strong, water-resistant, weatherproof

   • Good rebound capacity after compression

2. Cross-linked Polyethylene (XLPE) / EVA Foam

   • Lightweight, flexible, rot-proof

   • Excellent for tropical and coastal conditions

3. HD100 / HD200 Resin Board

   • High-strength resin-based boards for heavy-duty traffic areas

Installation Guidelines

1. Position the filler board vertically between concrete slab gaps before casting.

2. Ensure its flush with slab depth, leaving 10mm gap on top for joint sealant.

3. Fix it in place using nails, adhesives, or mechanical fasteners if needed.

4. After curing, fill the top gap with polysulphide or bitumen sealant.

Advantages

• Accommodates thermal expansion and shrinkage

• Prevents structural damage and water ingress

• Chemically and weather resistant

• Long-lasting and maintenance-free

• Complies with road authority standards
