ATEX
WAFFLE
MOULDS:
Atex waffle moulds are manufactured
in Polypropylene. This hard wearing
material allows, with a reasonable care,
for the moulds to be re-used over and
over again (over 100 times). It reduces
the impacts on the environment as well
as the amount of concrete and steel
needed. Atex means Sustainability.
S U S T A I N A B I L I T Y
Reduced
use of
concrete
and steel
E C O N O M Y
Up to
40%of reduction
in the use
of these
materials.
As it is deeper than the regular slabs with
the same inertia levels, the Waffle Slab
reduces the need for the use of steel, thus
lending feasibility to the construction of
larger spans, with fewer columns and
reduced concrete consumption.
The total weight of a building with Waffle
slabs is at least 15% lighter. As a result,
excavation, foundation and construction
costs are proportionally reduced.
Compared to traditional slabs, the
Waffle Slab is more economic as it
dispenses with the use of any concrete
that has no structural function.
Atex means Economy.

The company has
a solution for solid
slabs - Planex System,
as well.
Atex means flexibility.

150 times
Atex waffle moulds are manufactured
in Polypropylene. This hard wearing
material allows, with reasonable
care, for the moulds to be re-used
over and over again (over 150 times).
It reduces the impact on the
environment as well as the amount

Reference
in design
The use of Waffle Slabs in commercial and residential projects
has become a trend in interior design and architecture.

Safe
Follows the
directives of
ACI - Eurocode
in case of a fire
The moulds have been tested by
the British Construction Industry
Research and Information
Association and copies of this
detailed report, 107 are available
from the Association.
Extensive testing to determine the best
material, internal ribbing design and load
capacity at varying temperatures resulted
in a high quality mold. They have been
used in a wide variety of climates and
temperatures, from Iceland to Saudi Arabia.

Tubex
Tubex, the product demanding patent, was develo-
ped to run the Atex slab by using horizontal holes.
This eliminated the use of concrete with no struc-
tural purpose for both the wells and the holes
resulting in a 10% economy of concrete usage,
when compared to ribbed slab without tubes.
Tubex is an evolution of the PVC pipes that are tra-
ditionally cut and placed between the buckets in
order to form the hole.
The ribbed slab with the holes permits the ins-
tallation of ventilation ducts, hydraulic pipes and
electricguttersfittedintothethicknessoftheslab.

The saddles were developed for
the construction of one-way span-
ning systems. Using this part be-
tween the moulds for two-way ri-
bbed systems, the rib that would
be formed between them is eli-
minated, and a one-way spanning
slab is shaped.
This is an Atex product, paten-
ted and can be used by the Atex
families 610U, Atex 640U, Atex
655U, Atex 685U, Atex 755U, Atex
800U, Atex 830U and Atex 875U.
Atex Saddles®
has a unique
fixation system developed so as to
guarantee it fits perfectly in with
the moulds.
This will prevent the set from sagging
and maintains the saddle in
the right position while the
concrete is being poured.
Saddle
The part that fixes
the lower flaps of the
saddle guaranteeing
the maintenance of
its measures and
resistance to tensile
and shear.
Tie beam
Part to be
placed between
two Atex moulds.
*Saddle required between Atex 610 moulds.

Cabetex®
Atex Ruler
System
The company designed an innovative system - Cabetex System, used in any
type of Atex slab and any type of shoring. The heads of shoring (Cabetex) are
placed in previously defined places where the fixed shoring will be installed.
72 hours after the concrete is fixed, the provisional shoring can be removed,
but the fixed shoring, so that the slab does not suffer the stress.

Conclusion
25
26
The concept is to susbstitue the usage of
plywood in the applycation of concrete at
solid slabs for moulds made of plastic.
The structural project is developed in a
way to eliminate to the fullest the usage
of wood moulds in each gap. The Planex
is directly supported over secundary
beam in the same way as the plywood.
	12 advantages provided
by using the Planex system
	1. 	More productivity during the moulds assembly.
	2. 	More ergonomy at handling the mold.
	3.	Available for renting and selling.
	4. 	Durability of the moulds and greater re-use.
	5. 	Aproximately 85% reduce of all wood used.
	6. 	Applicable in every type of shoring.
	7. 	No need for specialized labor.
	8. 	Lower use of carpenter’s work.
	9. 	Do not deform in contact with rainwater.
	10. 	No disposed material.
	11. 	Reduces the use of energy and CO2 emission.
12. 	Less amount of shoring pieces.

Atex Technical Catalogue 2021 (Imperial)

  • 1. Technical Data Waffle: Atex 600, 610, 650, 660, 700, 740, 800, 900, Trough: 600U, 610U, 640U, 655U, 685U, 755U, 800U, 830U, 875U Formworks for Ribbed Slabs
  • 2. Atex has always dedicated itself to innovative and pioneering solutions for the civil construction market, by means of slab moulds. The Waffle Slab is a modern solution with ribbing connected by a cover or compression layer. More than 500.000.000 sf built with Atex system 2
  • 3. Why use theAtex Solution E C O N O M Y S A F E S T A N D A R D I Z E D S U S T A I N A B I L I T Y F I R E R E S I S T A N C E V E R S A T I L I T Y 3
  • 4. Committed to conduct business that generates positive economic results and benefits both the company and the customer, Atex products ensure cost savings during construction, ensuring higher productivity for projects and the entrepreneurs involved. S U S T A I N A B I L I T Y Its use reduces CO2 emissions by eliminating the use of wood during the construction and by decreasing the use of concrete and steel. Complies to LEED Certification with 27% of the required score. Atex products conform to the sustainable needs of the planet. The company`s moulds eliminate the need for cutting down trees. 3.5millions trees preserved 4
  • 5. ATEX WAFFLE MOULDS: Atex waffle moulds are manufactured in Polypropylene. This hard wearing material allows, with a reasonable care, for the moulds to be re-used over and over again (over 100 times). It reduces the impacts on the environment as well as the amount of concrete and steel needed. Atex means Sustainability. S U S T A I N A B I L I T Y Reduced use of concrete and steel E C O N O M Y Up to 40%of reduction in the use of these materials. As it is deeper than the regular slabs with the same inertia levels, the Waffle Slab reduces the need for the use of steel, thus lending feasibility to the construction of larger spans, with fewer columns and reduced concrete consumption. The total weight of a building with Waffle slabs is at least 15% lighter. As a result, excavation, foundation and construction costs are proportionally reduced. Compared to traditional slabs, the Waffle Slab is more economic as it dispenses with the use of any concrete that has no structural function. Atex means Economy. 5
  • 6. The company has a solution for solid slabs - Planex System, as well. Atex means flexibility. V E R S A T I L I T Y Waffle slab with beams, waffle slab on wide beams, waffle slab on drop panels, waffle slab on precast, waffle slab on metal frame works, waffle slab with horizontal holes and prestressed waffle slab. With more than 120 types that can be used in any kind of project Creating an intelligent and economic solution for different structural designs 6
  • 7. Atex waffle moulds can be re-used over 150 times Atex waffle moulds are manufactured in Polypropylene. This hard wearing material allows, with reasonable care, for the moulds to be re-used over and over again (over 150 times). It reduces the impact on the environment as well as the amount of concrete and steel needed. Atex means Sustainability. 7
  • 8. S U P P O R T S Y S T E M Standardized, clean, safe projects without the need for specialized labor. Easy assembly and removal of moulds, all done by hand. Industrialization of the construction process 8
  • 9. Building of huge free spans Waffle Slabs are ideal for the construction of spacious spans, using fewer columns. 9
  • 10. Reference in design The use of Waffle Slabs in commercial and residential projects has become a trend in interior design and architecture. 10

  • 17. Tubex Tubex, the product demanding patent, was develo- ped to run the Atex slab by using horizontal holes. This eliminated the use of concrete with no struc- tural purpose for both the wells and the holes resulting in a 10% economy of concrete usage, when compared to ribbed slab without tubes. Tubex is an evolution of the PVC pipes that are tra- ditionally cut and placed between the buckets in order to form the hole. The ribbed slab with the holes permits the ins- tallation of ventilation ducts, hydraulic pipes and electricguttersfittedintothethicknessoftheslab.

Using this part be- tween the moulds for two-way ri- bbed systems, the rib that would be formed between them is eli- minated, and a one-way spanning slab is shaped. This is an Atex product, paten- ted and can be used by the Atex families 610U, Atex 640U, Atex 655U, Atex 685U, Atex 755U, Atex 800U, Atex 830U and Atex 875U. Atex Saddles® has a unique fixation system developed so as to guarantee it fits perfectly in with the moulds. This will prevent the set from sagging and maintains the saddle in the right position while the concrete is being poured. Saddle The part that fixes the lower flaps of the saddle guaranteeing the maintenance of its measures and resistance to tensile and shear. Tie beam Part to be placed between two Atex moulds. *Saddle required between Atex 610 moulds. 19

  • 26. 26 The concept is to susbstitue the usage of plywood in the applycation of concrete at solid slabs for moulds made of plastic. The structural project is developed in a way to eliminate to the fullest the usage of wood moulds in each gap. The Planex is directly supported over secundary beam in the same way as the plywood. 12 advantages provided by using the Planex system 1. More productivity during the moulds assembly. 2. More ergonomy at handling the mold. 3. Available for renting and selling. 4. Durability of the moulds and greater re-use. 5. Aproximately 85% reduce of all wood used. 6. Applicable in every type of shoring. 7. No need for specialized labor. 8. Lower use of carpenter’s work. 9. Do not deform in contact with rainwater. 10. No disposed material. 11. Reduces the use of energy and CO2 emission. 12. Less amount of shoring pieces. Planex® for Slabs The Planex system for flat slabs is an innovation that Atex offers for the construction companies to optimize the executive process of solid slabs, in order to guarantee a cleaner, organized and ecologically sustainable work. 26
