Buying Guide: Key Purchase Considerations
- Material and flexibility:EPDM rubber is commonly preferred for expansion joints due to its elasticity and resistance to weather, cold, and heat. For small to mid-sized cracks, a flexible rubber strip can provide robust sealing; for larger joints, consider higher-profile fillers.
- Joint width and length:Measure the joint width (e.g., 1/2″, 1″, 3/4″) and total length needed. Many products are available in long rolls or multiple packs that you can cut to fit specific joints.
- Installation method:Some products require straightforward insertion and hand pressing, while others may benefit from tapping with a hammer or professional tools. Check if the filler is pre-cut or needs trimming.
- Weather and temperature tolerance:Choose fillers rated for outdoor exposure with resistance to UV, moisture, freeze-thaw cycles, and temperature fluctuations to prevent cracking or hardening.
- Durability under traffic:If joints will endure vehicle or foot traffic, select a filler with strong bonding and abrasion resistance to minimize wear over time.
- Maintenance and longevity:Consider products advertised as low-maintenance with long service life and reduced need for replacement or frequent resealing.
- Cost and coverage:Evaluate pack size versus project requirements. Some options provide longer lengths that reduce the number of joints to seal across larger areas.
- Compatibility with asphalt:Ensure the chosen filler bonds well with asphalt and concrete and remains flexible to accommodate ground movement without losing adhesion.
