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
r than in private building and where
having an aired interspace for placing pipes and installations has proved really advantageous.

A perfectly ventilated crawl space, insulated from the underlying ground, made of concrete
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
specific charts). The formworks must be arranged in rows from right to left and from up to down always
keeping the printed arrow upwards.
F) Placing of Fermagetto EXTENSION and FERMAGETTO made of polystyrene, preventing concrete from
penetrating into the crawl space and facilitating the construction of external kerbs and foundation beams
during the casting phase.
G) Laying of weight distributing reinforcement with a 6 mm minimum diameter and with a 20 x 20 mesh, necessary to stand stress.
H) Filling up of the formworks and casting of the top layer with concrete (Resistance class R’CK 250 Kg/cm2
and with 3 cm minimum thickness (see chart ). Work executed with or without the help of pumps.

A) Disposable formworks, type Modulo by Geoplast srl, made of atoxic,highly resistant, recycled and fully
recyclable polypropylene. These modular pieces, if correctly coupled, can form load bearing pillars with a
minimum support base of 135 cm2.
Each of them is ... X ... cm on the plan and ... cm in height and has a
concave cap with stiffners, specifically made to increase load capacity. The cap has flat reliefs among
which the slab reinforcement can be laid and concrete can be poured. (Actually the flat reliefs mark the
maximum height the cast can reach). The MODULO is dry laid and used for making ventilated floors; it is
certified by an authorized Institute and delivered directly to the building yard.
