Disclosed herein is a concrete form apparatus that can be utilized to establish a rigid perimeter within which concrete can be poured for curing. A first component of the concrete form apparatus can be composed of a flat rigid material that is rectangular in shape and includes perforations along the lengthwise dimension of the material such that, when the material is folded along the perforations, an internal cavity is formed. The second component of the concrete form apparatus can be composed of a material having dimensions sized in accordance with the internal cavity of the folded material such that the first component can be folded along the perforations in the manner described above to encapsulate the second component within the internal cavity. Adhesive layers can be applied to prevent the concrete form apparatus from separating, and layers of the concrete form apparatus can be coated with a waterproofing substance.

A pliable mold useful for forming concrete columns includes protrusions and/or recesses which form decorative complementary recesses and/or protrusions on the resultant column.

Buildings are constructed using the tilt-up technique from concrete elements that have contours that are at least partially curved. The concrete elements are made by casting in molds. The molds are assembled from mold pieces selected in a kit that contains a limited set of shapes. Molds assembled differently can produce concrete elements with a large variety of contour shapes.

A modular panel made of plastic material for manufacturing pool walls comprises: a generally rectangular main body of which a first surface is intended for being oriented toward the inside of the pool, the lengths of the main body defining a reference plane; a complementary body capable of being attached to a second surface of the main body and defining a hollow column intended for receiving concrete, wherein the first surface has an initial convex transverse curve on the width of the main body in a plastic injection mold, the maximum amplitude of the transverse curve relative to the reference plane being selected to compensate for all or part of the deformations that occur between the removal from the mold and the setting of the concrete, in the transverse and longitudinal directions.

Features for formliners to form a decorative pattern in a curable material and methods of using the same are disclosed. An improved formliner is disclosed with substantially seamlessly connecting components that reduces the need for using adhesives for interconnecting a plurality of formliners in a pattern. Further, the formliner is configured to reduce and/or substantially eliminate visible seams in order to create a more natural appearance in a finished product of the curable material.

The invention comprises a concrete form. The form comprises a first concrete forming panel having a first primary surface adapted for forming and contacting plastic concrete and a second primary surface opposite the first primary surface; a layer of insulating material contacting and substantially covering the second primary surface of the first concrete forming panel; and an insulating blanket adjacent the first concrete forming panel. A method of using the concrete form is also disclosed.

The present invention relates to a system for light-based signal exchange between a plurality of formwork panels (P). The formwork panels (P) are equipped with a light hub (LH) which serve to transmit light pulses in a light channel inside the formwork panel (P) to the directly adjacent panels. Respective acknowledgment signals are received in order to discover the existence of the other light hubs (LH) being present in the constructional setting. All the signals are aggregated in one master light hub (mLH) which is in data exchange to a main unit (MU), which may serve as gateway to a secondary computer system (2C). The data transmission is executed according to a predefined protocol.
