WHAT IS A VENTILATED CRAWL SPACE ? The ventilated crawl space in house building is an air space built under the ground floor with insulating function, specifically aimed at preventing water infiltrations and upward dampness spreading. Not long ago, the traditional ventilated crawl space was made of loose dry stones and provided with ventilation grooves or better with hollow tiles laid on low walls placed at a short distance one from the other. The high cost of the traditional crawl space did not allow extensive use (actually it was used for particular spaces or where the building costs made it possible). NOWADAYS with the MODULO system the builders’ privilege, but a requirement for a fast developing sector. CRAWL SPACE is no longer a few The MODULO is a disposable formwork making the construction of crawl spaces and interspaces possible in a quick and safe way. Thanks to its U shaped fitting joint it enables a worker to lay about 100 square metres of it per hour, consequently

reducing labour costs by at least 80%. Moreover, the resulting surface is dry and can be walked on, thus ensuring greater safety in the building yard during laying and concrete casting phases. The low cost of laying work and of the modular formwork itself has made this product a valid substitute for materials such as gravel, which have a lower price, but definitely higher labour costs. The shape of the MODULO formwork has been projected to obtain very good ventilation and the minimum resistance to the air in the element intrados, provided the interspace is connected through pipes with the outside of the building. The in-coming pipes are to be preferably placed north and at ground level, the out-going ones south and driven up to the roof. This arrangement eliminates dampness and possible concentration of RADON gas. If compared to the traditional CRAWL SPACE, the MODULO creates a reinforced concrete structure that makes its use possible in industrial building yards where loads are highe

and mudular disposable plastic formworks, type MODULO Geoplast Srl. A) Floor rough made of rolled scree with variable thickness as per chart B) Layer of lean concrete with variable thickness as per chart C) At the builder’s discretion, before placing the formworks, holes and/or chases can be made for the passage of pipes or of all sorts of installations. D) The floor will be ventilated by making 80/120 mm diameter holes on the outside walls, one every 3.50/4.00 metres and possibly provided with connecting PVC pipes and external stainless steel grates equipped with anti-insect plastic nets. For a better ventilation the holes will have to be made at a higher level on the south, warmer side of the building rather than the north, colder side. In case there are parts of crawl space inside the foundation beams these will have to be connected with the outside or peri-meter portions. E) The Modulo will be laid over a lean concrete slab, previously prepared and with a suitable thickness (see
