What do you fill expansion joints with?
Expansion joints must be sealed with a flexible sealant, like QUIKRETE® Self-Leveling Polyurethane Sealant or QUIKRETE® Non-Sag Polyurethane Sealant…or an expansion joint strip, to prevent water from penetrating the joint and deteriorating the sub-base.
What is expansion joint foam?
Foam Sales Expansion Joint Foam is a cross linked, closed cell, polyethylene foam that is flexible, compressible, moisture and tear-resistant, light weight and durable. It has good recovery from compression, is resistant to common acids, alkalies, and chemicals, and is CFC free.
What is preformed joint filler?
EXPANSION JOINT FILLER is a preformed, non-extruding resilient joint filler, saturated with high quality bituminous materials having excellent preserving characteristics and excellent compressive and recovery capabilities.
Can you put sand in expansion joints?
Specially treated super-fine sand (Silica Sand) that has been washed, filtered for even particles and heat dried to reduce the weight so it does not sink and spreads evenly over the surface of caulk used to replace expansion joints or to repair cracks in concrete.
Is expansion joint foam waterproof?
What is Abelflex? The technical (confusing) answer: Abelflex is a closed-cell, cross-linked, 100% polyethylene foam expansion joint and space filler strip. This means that Abelflex is a plastic foam that has bubbles in it that aren’t linked so water can’t run through it.
What kind of sand do you use to fill expansion joints?
Silica Sand
Specially treated super-fine sand (Silica Sand) that has been washed, filtered for even particles and heat dried to reduce the weight so it does not sink and spreads evenly over the surface of caulk used to replace expansion joints or to repair cracks in concrete.
Can you use expanding foam for expansion joints?
Yes. Just an expansion piece for the base slab.
Do expansion joints need to be sealed?
Expansion joints need to be sealed periodically to protect against water, dirt, and debris. These elements can hurt the structural integrity of concrete over time. Water can also lead to mold and interior leaks that are costly to repair.
