Echo-Stone is our exterior or interior aggregate stone finish cast into our cement product. Echo-Stone is a unique material that simulates cast or cut stone. It is a careful blend of cementitious minerals, aggregates, polymers and glass fibers. It is lightweight, strong and versatile stone finish that can be cast into difficult configurations and shapes such as cornices, columns and radius forms. Since it is a cement based product, it is perfect for heavy traffic areas where the feel of “cold” stone is required.
Echo-Stone is available in a variety of standard colors, but we can custom match a color to your specification using natural aggregates and pigments. We are often required to match natural stone, pre-cast concrete or masonry. Since we can cast parts into specific and exacting shapes, Echo-Stone can be used to match the items that either too heavy or too expensive to make out of other building materials. We can cast Echo-Stone in a thin 3/8” thickness, the parts may appear to be cut stone but are far less expensive to support and install.
Also consider DEC’s Cornicestone FRP material when you have either very large profiles or large cornice conditions. Cornicestone will match Echo-Stone in appearance, but it is fabricated to be significantly less weight. This allows for the use of Cornicestone on large, elevated areas of the building and the use of Echo-Stone on the lower elevations where the public has access to it. This will achieve a universal appearance, but it will be less costly to install on the building. The combination of products is designed to match the best material for each application since each material has its advantages. This system approach provides a solution for your architectural vision.
