Elastizell Corporation of America
Albuquerque International Library
Project Details
As part of the revitalization of the International District in Albuquerque, construction of a new library began in early 2021. It was decided that several solar panel arrays would be included in the design to reduce energy demand for this project. Elastizell lightweight insulating concrete was installed over a Carlisle Vapor Barrier system over a galvanized metal deck and was covered with a Carlisle single ply membrane. This system provides a solid substrate for the membrane and offers topside fire protection.
Jasper Avenue
Project Details
When the Edmonton Convention Center was constructed, a layer of unstable silty soil was discovered below the foundation site. Reducing the load of the structure on this unstable soil became a priority. In all of 1982, approximately 3,000 cubic yards of Class III Elastizell Engineered Fill were placed over the roof of the convention center as a base for Jasper Avenue. In 2020, the City of Edmonton decided to widen Jasper Avenue as part of the Jasper Avenue New Vision (JANV) project. The existing roadway (including the Elastizell EF) was removed to replace the waterproofing over the roof of the convention center. Because of the long-term performance of the Elastizell EF from the casting in 1982, Elastizell EF was again chosen as a lightweight filler to limit the overall load. An additional 2,000 cubic yards of Elastizell EF was installed, with a specified maximum cast density of 32 pcf and minimum compressive strength of 75 psi.
Evangelical Deaconess Hospital
Project Details
When were the earliest Elastizell low-density insulating concrete roof decks installed? Recently, we discovered these pictures in our archives – a roof deck project installed by Elastizell when the company was located in Alpena, MI. Unfortunately, we have very few details on this project, but we know this was a portion of the addition to the Evangelical Deaconess Hospital in Detroit, MI. The addition to the hospital was dedicated in December 1957. As best we can tell, the roof deck was cast in the spring/summer of 1957. It’s assumed that a built-up roof membrane system was installed over the Elastizell deck.
Pismo Beach Pier Plaza
Project Details
Project Name: Pismo Beach Pier Plaza
Project location (City, State): Pismo Beach, CA
Volume: 1,500 cy
Fill type: Plaza, weight-reducing fill
Date of Completion: 2020
Elastizell Applicator: Cell-Crete Corporation
General Contractor: Vernon Edwards Constructors
Reason EF was needed:
The Pier Plaza project in Pismo Beach is a $6 million project that will update the plaza surrounding the pier. This outdoor section will be reserved to hold future concerts and special events.
As this project is located directly on the waterfront on beach sand, a lightweight fill was required to reduce the overburden on the subgrade, which had poor bearing capacity. Elastizell Engineered Fill (EF) eliminated the need for soil improvement techniques. Cell-Crete Corporation was able to create a 25% slope out, creating a children’s slide from the top of the plaza to the beach sand.

Southeastern Roof Decks, Inc. cast Elastizell Lightweight insulating concrete over an existing structural concrete deck on the Macon City Auditorium reroof project. This deck surrounds the famous copper dome (claimed by some to be the largest in the world). The nearly 100-year-old auditorium has been in service for nearly 100 years. After the Elastizell roof deck was cast (40 pcf with a minimum 300 psi), the system was covered with a Fibertite Fleeceback Membrane. Interesting facts: Nearly 100 year old structure in Macon, GA, that has hosted performances, meetings, and events since 1925. The great hall seats 2,688 people. Completed at night to beat a bad storm that was moving in.
Stanford Escondido Village Graduate Residences
Project Details
Project Name: Stanford Escondido Village Graduate Residences
Project location (City, State): Escondido, CA
Size (Squares/Square Feet): 196,000 sq ft
Substrate (metal deck, structural concrete, wood): Structural Concrete
Membrane type: Single ply
Date of Casting: September 2018
Owner: Stanford University
Escondido Village Graduate Residences Project consists of 4 buildings with a combined roof area of approximately 196,000 sq ft. The roofer brought in Elastizell lightweight insulating concrete (LWIC) as a value engineered change to the tapered insulation originally specified for the project. Elastizell LWIC was installed with stepped EPS for sloping to drain and an average R30 R-Value. The Elastizell LWIC is the perfect material for the new single ply roof membrane being installed.
Lloyd Expressway (State Route 62)
Project Details
Project Name: Lloyd Expressway (State Route 62)
Project location (City, State): Evansville, IN
Volume: 75,000 cubic yards
Fill type: Backfill between MSE Walls
Specified Density/Strength: 27 pcf, 40 psi
Date of Completion: 1998
Applicator: Elastizell Systems, Inc.
The existing 50-span bridge was built in 1953, spanning the Pigeon River. By 1997, the bridge structure had deteriorated and needed to be replaced. As the original structure was built over an old landfill, long lengths of pilings would be required. As an alternate, 75,000 cubic yards of Class II (maximum 30 pcf, minimum 40 psi) was cast over a 705-foot length, 105 feet wide, and in thicknesses from 27 to 32 feet in depth. 65,000 cubic feet were placed between August and November 1997, while traffic was maintained on four of the lanes. The final 10,000 cubic yards were placed in 1998, with traffic switched over to the section completed in 1997.

Pomona College Studio Arts College
Project Details
Project: Pomona College Studio Arts College
Location: Claremont, CA
Applicator: Cell-Crete Corporation – Monrovia, CA
Roof Insulation: Elastizell Low-Density Insulating Concrete Roof Insulation over Wood Decking
Membrane: Sika Sarnafil G410 Fleeceback membrane fully adhered
Completed: 2014
Awards: LEED Gold Certification, 2106 Gold Circle Award honorable mention by Eberhard Roofing
This award winning project at the Pomona College Studio Arts College used a combination of Elastizell Low Density Insulating Concrete and EPS insulation board over a wood deck. Elastizell was chosen for this project not only because it saved a substantial amount on the project, but because it was much easier to cast the deck to the contours of the “wave roof”. The 32,000 square foot project (completed in 2014 by Cell-Crete Corporation of Monrovia, CA) was cast at R-30 minimum. The Elastizell deck was covered with a Sika Sarnafil G410 Fleeceback membrane, which was fully adhered. A series of 48 Suniva PV solar panels was installed on top of the G410 membrane, which will supply the building with solar-generated electricity. This project was certified LEED Gold in 2016.
