As people occupy a space, they bring life to what was previously a static environment. They live, interact and make memories uniquely their own that are merely contained within a defined environment. The inspiration for the Memory Wall was for these interactions to create and redefine the space where they take place. Concrete is the best material for this as it can take any shape imposed on it by it’s surroundings. Occupants of a space can record the memory of their interactions on the concrete by altering the form. The Memory Wall formwork begins as a standard kit-of-parts of steel. The frame is assembled with a layer of rubber latex pinned between steel frames on both front and back faces. Rubber latex is a malleable material that is highly resilient. Bolts are then attached to the steel frame at regular intervals through hex nuts welded to the frame. Individuals can adjust the bolts in order to shape the rubber latex into unlimited unique shapes. After a predetermined amount of time, fluid concrete will be poured into the mold. When the concrete completely sets, the memories of those who spent time in the space become a permanent part of that time tile. As the mold is removed, reassembled and the molding process is repeated, time has a significant impact on the wall. Future occupants have the opportunity to see the impressions of those who came before them and then leave their own impact on the wall. All parts of the form are reusable in order to efficiently use materials and minimize waste. After a certain number of uses the rubber latex layer will need to be replaced, but this is a natural, inexpensive material, which can be recycled. Although the form is exactly the same for every cast, after people interact with it, it will never create the same piece of concrete. Ones the tiles are cast, they can be moved and combine to define any program. By its very nature, the Memory Wall is a flexible component that can be utilized in a variety of spaces while being unique every time.

Concrete is by its own nature a sustainable material because of its durability and longevity with minimal maintenance. Additionally, the forms used to cast concrete are used for multiple pours, and utilizing the forms in this way is both cost efficient and sustainable. By using the “Impressions” form, the same form is used to create many different pieces, each unique from each other even though they utilize the same form work. Points of varying depth manipulate a layer of natural rubber latex on the bottom of the form. Because of this process, one face of the form is completely variable and can be programmed into many different shapes.

Halftone is a reprographic technique that translates pictures into a matrix of dots. Increasing sizes of dots where larger dots make up a darker area and smaller dots make up lighter areas represents the color gradient in the image. For the “Impressions” precast system the size of these dots was assigned a number from 1-5 based on their size. This number code became a measurement of depth so that dots labeled 1 are the deepest and 5 are the most shallow. Through this system, the darkest area on an image translated into the deepest points in the concrete. Ultimately, a translated version of the original image is imprinted into the concrete.

The “Impressions” formwork is assembled from a simple kit of parts including ¼” cut sheet metal panels with custom perforations, custom steel side panels, 98 peg keys, a natural rubber latex roll, a steel top plate and ¾” -10 x2” hex bolts with nuts. The lock panel is assembled from the eleven 7’ x12’ cut sheet metal panels and has 98 contact points. The steel frame is assembled from the custom steel side panels and then used to compress the natural rubber latex against the lock panel. This material was chosen because of its high stretch ratio and resilience. It is harvested from the Para rubber tree by tapping so no trees need to be cut down in order to create the rubber latex adding to the form’s sustainable qualities. Peg keys are inserted into the locks from under the bottom of the lock plate with depth set according to the predetermined code. Assumedly, the setting of these depths will be mechanized and the picture coded into depths by a computer program. The pegs stretch the rubber latex in order to create a custom shape. Concrete is then poured into the mold and covered with the steel top plate.

This process can be repeated as often as necessary by simply cleaning out and reassembling the mold. The finished concrete wall panels can be lifted by a crane and fit together with slots cast into the sides of the panel. All of the form materials may be reused as the steel is very durable and the rubber is highly resilient. This enhances the already inherent sustainable properties of the precast concrete process.
