General Notes Hollow-Core slabs conform to the current edition of CSA A251, “Qualification Code for Manufacture of

Architectural and Structural Precast Concrete.”

Estimated values of cambers and deflections can be supplied upon request.

For superimposed loads greater than 10 KPa and fire resistance ratings greater than 2

hours, special design requirements may be necessary.

Fire Resistance Ratings Precast prestressed concrete elements can be provided with any degree of fire resistance that may be re-

quired by building codes, insurance companies and other authorities.

The fire resistance of building assemblies is determined from standard fire tests as defined by ULC Stand-

ard CAN4-S101-M82 “Standard Methods of Fire Endurance Tests of Building Construction and Materi-

als”.

Sound Rating Mandatory sounds insulation requirements between adjoining dwellings are generally specified in building

codes and equivalent regulations. For example: City of Vancouver Building By-Law 6164, requires a

Sound Transmission Class (STC) of 50 for all residential suites. It has been shown by extensive research

that the STC rating of various components is related to the surface density of the materials*. The Impact

Insulation Class (IIC) is derived from ASTM Standard Method E492, “Laboratory Measurements of Im-

pact Sound Transmission Through Floor Ceiling Assemblies Using the Tapping Machine.”

*See CPCI Metric Design Manual, 4-th Edition, Chapter 6-21

LEED POINTS INFORMATION FOR OUR PRODUCTS

Core floor Hollow-Core Slab produced by Expocrete and associated materials can be applied for

LEED rating. The following information can be used as a guideline for potential LEED credits.

Each project will require job-specific calculation, which could be provided by others.

* Aggregate in concrete mix Used with 100 miles of quarry location

* Korolath Bearing Pads

(placed at plank bearing ends)

10% - 60% Post Consumer Recycled Content

* Precast-Prestress Hollow-Core

slabs

Reduce heat required in construction site

specially in winter time.

All components of our concrete mix are manufactured within 300 miles of our plant. Information on

all suppliers, locations, and letters of recycled content are available upon request.

* Prestress Low relaxation studs

reinforcing contains

1-10% of recycled content

* Precast product shipping Usually within 800 km radius of our plant location

Expocrete will not accept any liability or responsibility on grants in LEED Points
