What is a compressible filler?
Compressible fillers are substances that will compress when subjected to pressure. These substances are used in place of air in the concrete mixture to reduce its weight and increase its strength.
What is Flexcell?
Flexcell is a bitumen impregnated wood fibre board, which is ideal for use as an expansion joint filler. It offers excellent compressive and recovery properties. It is simple to handle and install. It is used when concreting areas and requiring expansion joint.
What do you put in between concrete slabs?
An expansion joint is a material placed in the cracks (or joints) between concrete slabs to protect the slabs from cracking when they contract and expand as the temperature changes. This material acts as a shock absorber, absorbing the stress from the slab’s movement.
What is pre Moulded joint filler?
Expansion Joint filler’ is a cross-linked, pre-moulded, high performance joint filler board. It is readily compressible and ensures low load transfer.
How do you fill a large gap between paving slabs?
Filling large gaps between paving slabs can be easily achieved with wet brush-in joint filler or polymeric sand. Wet brush-in filler is more flexible, making the joints less susceptible to cracking as the temperature changes throughout the year.
Should you fill expansion joints?
Just remember that expansion joints should always be sealed and filled with a flexible joint sealer and never epoxied or coated over. Contraction joints can be filled in the same manner after a coating or sealer is applied if you desire.
What do you use to fill expansion joints?
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 joint filler?
Joint filler is a material that is used between two sections of concrete, which in contrast to concrete, is a relatively compressible material so that it will not fail as the concrete around it grows and shrinks due to temperature changes or movement.
What is joint filler used for?
A joint filling is used to prevent these cracks from growing and damaging the concrete in such cases. The joint filler is a material that will hold the two materials it sinks in between firmly together. Therefore, it is seen as cement or plaster based.
What would happen to a bridge without expansion joints?
1 Answer. Expansion joints prevent build up of resonant frequencies, which dangerously amplify the swaying motion of bridges. Without such joints, bridges are liable to collapse.
How do you fill a large gap in flagstone patio?
Rocks: You can use small rocks to fill large gaps, and gravel or crushed rock can be used to fill smaller gaps. Mulch: Bark and lightweight chunks of mulch are a great option for in-between flagstone. Cocoa shell mulch is small and curls, for a unique look.
