What is compressible filler material?

What is compressible filler material?

GeoSpan® and GeoVoid® compressible fill materials are expanded polystyrene (EPS) products designed to act as a compressible medium between swelling soils and structural elements. Compressible fill material design criteria are provided for each application in a design summary for review by the project design engineer.

What is compressible filler board?

Description. Bitucell is a compressible joint filler and protection board manufactured from bitumen impregnated wood fibres. It is supplied in sheet form and is used to form and fill expansion joints in in-site and precast concrete construction.

What are the materials used for concrete joints?

Welcome back.

• Asphalt, tar, bituminous materials.
• Fibre and fibre products.
• Sponge rubber.
• Cork.
• Polymer.
• Thermoplastic.
• Glass.

What is expansion joint filler?

EXPANSION JOINT FILLER is designed to relieve compressive stresses which develop when concrete expands in either horizontal, vertical or inclined directions. EXPANSION JOINT FILLER prevents the intrusion of foreign material into the joint which would prevent the joint from working.

What is compressible filler used for?

It is used under concrete grade beams, under some structural floor slabs, and against foundation walls. GeoSpan compressible fill material acts as a medium between the expansive soil and the structure to reduce stresses transferred to the structure.

Is used as filler material in joint?

Rubber, asphalt and other compressible materials are popular joint filler material choices. Joint filler also prevents the introduction of other materials that are not compressible from entering the joint, which could cause concrete failure as well.

What are the two methods used for prestressing?

What are the two methods used for pre-stressing? Pre-tensioning and post tensioning.

What is a compressible material?

A compressible material is placed between adjacent foundations subjected to vibration and/or impact forces, or between adjacent foundations dissimilar in mass and stiffness and movement. The compressible material minimises damage to the foundation when the adjacent foundations move towards each other.

What are the two basic methods of protecting exterior joints?

What are the two basic methods of protecting exterior joints? Exterior joints provided on the walls are subjected to expansion and contraction. If any foreign body like rock enters the joint, the object may cause the materials on each side to spall or crack. Chapter 26, Problem 9RQ is solved.

Which is the best compressible fill material for concrete?

GeoSpan acts as a compressible medium for applications such as under concrete grade beams, structural floor slabs, & against foundation. GeoSpan compressible fill material is designed specifically to meet the structure requirements for each application.

Which is the best filler for expansion joints?

It is a chemical-resistant, ultraviolet stable, non-absorbent, low density, cost-effective, compressible foam that offers an extended service life in both interior and exterior applications. DECK-O-FOAM expansion joint filler is a flexible, lightweight, non-staining, polyethylene, closed-cell expansion joint filler.

How is closed cell polyethylene filler used in construction?

Low density, compressible, closed cell polyethylene filler for structural expansion joints and building facades Low compression – accepts temperature cycles with minimal load transfer. Closed cell – prevents water absorption. Recovery – 90% after release of load.

What can geospan compressible fill material be used for?

Where long-term soil movement can be predicted, GeoSpan compressible fill material can be designed to reduce the forces that would be induced on structures by soil movement, thus reducing the likelihood of damage to the structure above.
