A Division of Robert Weaver Masonry

About Us


Robert Weaver Masonry was established in 1978. As time went on Robert Weaver paid close attention to new products available to the building industry and thus discovered ICF (Insulated Concrete Forms). In 2000 Lancaster ICF had the opportunity to build their first ICF walls and since have built more than 70 structures in the residential and commercial fields.

As time went on and the ICF industry continued growing, in 2007 the name became officially known as Lancaster ICF Builders, a division of Robert Weaver Masonry. As a company Lancaster ICF has one goal. To exceed your expectations through quality workmanship and professionalism.
