FOAMJOINT 75 mm × 25 m – 70251 (Single Pack)

FOAMJOINT is a premium-grade, closed-cell, cross‑linked polyethylene foam expansion joint roll—engineered for structural concrete applications requiring durable gap-filling, sealant backing and joint movement accommodation. The variant 75 mm × 25 m, identified as MPN 70251, comes as a continuous one-piece extrusion, ensuring uniform performance without delamination.

Key Features

Closed-cell, impervious foam: completely resists moisture, sealing gaps against water, dust and contaminants.
Cross-linked structure: delivers excellent compression recovery after load, essential for long-term expansion joint performance.
Lightweight and easy to handle: highly compressible and simple to cut or form on-site.
Chemical and environmental resilience: resistant to fungi, insects, diluted acids, alkalis, oils, solvents, UV and thermal extremes (–40 °C to +95 °C).
Compatible with most liquid sealants: functions effectively as a bond‑breaker and sealant backing support.

Variations Available

FOAMJOINT (marketed as Abelflex by Sika or Ableflex expansion joint foam) is supplied in a broad range of standard widths, all at 10 mm thickness and 25 m roll length:

Width (mm)
50
75
100
125
150
200
250
300

Additional thicknesses (15–100 mm) available in wider rolls or sheets for higher joints.

Some variants include a pre‑slit or “zip-top” edge, roughly 10 mm from one side. After concrete curing, the zip-strip is easily torn off to leave a clean recess for sealant application. When sealant is not required, the zipping should face downwards to avoid unintended removal.

Typical Applications

Ideal for floor and wall expansion joints, roadways, bridges, driveways, patios and industrial slabs—where movement control, debris blocking, and sealant compatibility are essential. Acts as both a bond-breaker and void filler, supporting structural integrity and sealant performance.

The FOAMJOINT 75 mm × 25 m (MPN 70251) offers top-tier joint-filling performance—closed-cell, cross-linked foam, robust recovery, chemical and weather resistance, and compatibility with sealants. Available across multiple widths and optional zip‑top design, it provides versatility and reliability for concrete construction and expansion-control needs.
