These two concrete archways located on Interstate 95 at Clayton Road in Delta, Pennsylvania, 17314 were prefabricated in a shop using EPS29 Geofoam as the form. The EPS29 Geofoam arches consisted of 3 pieces creating a 64 inch x 128 inch wide x 48 inch deep arch that was then placed on top of conventional steel forms on site. The EPS form used a patented system by Universal Foam Products to attach the EPS to the plywood and lumber support without the use of any adhesives. The EPS29 Geofoam, with a compressive strength of 10.6 psi @ 1% deformation, was used to ensure the arch would be perfectly formed.
EPS form liners are used extensively in the construction industry to form archways, jersey wall, intricate facades, manholes, complex utility vaults, vertical and horizontal bridge supports and many other items. The material is extremely lightweight making it easy to handle. It can be provided in an infinite number of configurations and is strong enough to be able to handle intense loads with no deformation. In most applications EPS forms are substantially less expensive than steel or wood alternatives. The forms ship from locations throughout the United States.
