The formwork used when building concrete structures has a significant influence on the quality of the concrete’s surface because it imprints its own texture. The poor quality of formed concrete surfaces is a problem that is widespread in civil engineering and architectural works. In addition to creating an esthetic problem, this irregularity of the surface renders it more vulnerable to elements in the immediate environment. This phenomenon is even more common with structures exposed to harsh weather.
When pouring concrete, the operation which consists of uniformly spreading the mix inside the formwork through the use of vibrations leads to a migration of excess water to the surface, which weakens the primary layer. Often watertight, the formwork does not allow for the drainage of bleeding water that remains on the periphery.
Drainaform is composed of a single textile layer with two different surfaces. The smooth side, which is in contact with the concrete, serves as a filter and prevents the washout of fine cement particles. The fibrous side acts as a drainage component to remove excess surface water and air. Helping to maintain the water-cement ratio and minimize laitance problems, it also helps to improve the strength and durability of the top concrete layer, in addition to giving it a more uniform appearance. In short, Drainaform helps to effectively protect the concrete against aggressive elements such as water, de-icing salts, and freeze-thaw cycles.
