MevaLite
MevaLite is a modular formwork system that can be either handset or
gang formed. It is suitable for use on residential, commercial, industrial
and highway projects.
The panels are composed of closed profile powder coated aluminum
frames and a high grade alkus composite facing that provides an
excellent concrete finish. Panels are connected with the MEVA assembly
lock which results in fast and ecient assembly with no nuts and bolts.
A complete formwork assembly including accessories weighs about 12
psf. Panels are designed for a maximum lateral concrete pressure of 1350
psf when properly supported.
MevaLite panels are available in 4 different heights (9’, 6', 4’, and 3’) and
in 5 different widths (3’, 2’, 1’-6”, 1’-0”, and 6”). In addition, 2’-6" wide
multi-purpose panels are available in each height. These panels have
multi-adjustment profiles for placing ties or column clamps and are ideal
for forming 90° corners, columns, pilasters, and connections to existing
walls.
Introduction
Available accessories include aluminum fillers (1”, 2”, and 3”), inside
corners (12”x12”), outside corners, push-pull props, and walkway
brackets. Threaded nuts built into the panels allow for easy attachment
of accessories.

Recommendations:
ÆThis manual contains information and instructions on how to use
MEVA equipment in a safe and ecient manner. All construction
personnel involved with the use of this equipment (“User”) must be
familiar with the contents of this manual.
ÆThe user is responsible for identifying and complying with all
applicable government regulations, codes, and ordinances in the use
of this equipment.
ÆMEVA equipment must be erected, used, and dismantled in
accordance with this manual, safe practices, and all applicable
industry standards developed and published by the American
Concrete Institute (ACI), the American National Standards Institute
(ANSI) and the Occupational Safety and Health Administration
(OSHA). Additional workplace safety precautions should be taken
where necessary.
ÆMost examples shown are standard applications that will occur in
practice most often. For applications not covered in this manual,
please contact your MEVA representative for advice.
ÆMany of the details in this manual show specific conditions and
situations during different stages of assembly and are therefore not
always complete. Any equipment or safety accessories not shown in
the details must still be used in accordance with all applicable rules
and regulations.
ÆIn order to assure proper fit and load capacity, do not combine this
equipment with components of other manufacturers unless directed
by a MEVA representative.
ÆThe user must inspect all equipment before each use. Never use
equipment that is damaged, deformed, or weakened due to wear or
corrosion.
ÆNever oil or wax MEVA assembly locks.
ÆThe user must ensure the stability of all components during all
phases of construction.
ÆFor gang formwork, the user should always establish the number
and location of lift points to equalize load on lift brackets and
ensure that no individual component is overloaded.
ÆIt is the user’s responsibility to adjust the pour rate and placement
methods in accordance with ACI 347 for the concrete mixture and
the specific jobsite conditions at the time of placement so that the
specified maximum lateral concrete pressure is never exceeded.
ÆCertain applications will result in a maximum lateral concrete
pressure lower than the system panel capacity. Refer to specific
sections of this manual, MEVA application drawings, or consult your
MEVA representative.
ÆWhen stripping gang formwork, never use the crane to break the
concrete bond. Instead, use suitable tools such as pry bars or wood
wedges. Secure the lift brackets prior to removal of ties, anchors,
and/or bracing.
ÆDo not nail into aluminum panel frames.

The poly-propylene and aluminum
composite forming face has all
the positive properties of plywood
plus important advantages: longer
life span, greater load-bearing
capacity, better nail-holding ability,
fewer and easier repairs, 100 %
recyclability.
Besides the obvious advantages,
such as considerably reduced
cleaning effort, minimum
consumption of release agent
and an excellent concrete finish,
alkus offers substantial ecological
benefits. Substituting plastic
for wood saves valuable timber
resources. Also, the release of
highly toxic dioxin is avoided,
which is released in the process of
burning plywood (that is bonded
with phenolic resin). Used or
damaged alkus plastic sheets can
be recycled into the same product.
It is 100% recyclable, and the
manufacturer guarantees reaccept-
ance.

The panels are connected
quickly and eciently with the
EA-assembly lock regardless of
their orientation (Fig.7.1, 7.2).
The lock can be attached on the
frame at any position, and its
5-point contact not only draws
the panels together but aligns
them as well. Only a few hammer
blows are needed to create a
safe connection with perfect
alignment. Since the lock weighs
only 3.3lbs. it can be handled
easily.
Standard lock requirements are
shown in Figure7.4. Additional
locks are required for columns
and outside corners (refer to
respective sections for details).
Panels with aluminum or wood
fillers in between are connected
with the Uni-assembly lock22,
which can accommodate a
maximum filler width of 6.5"
(Fig.7.5).

Tie Placement
The tie pockets, where the ties can
be inserted, are located adjacent
to the panel frame. The size of
the pockets (Fig.12.4) allow one
or both sides of the wall to be
inclined. On sloping formwork
the articulated flange nuts 15/120
have to be used. These flange nuts
can be easily installed by using
a hammer or a spanner. In order
to secure the formwork against
uplift it has to be anchored to the
ground using shoe plates or other
means.
Please note:
If two panels of different widths
are assembled side by side, the
ties should be placed through
the panel with the larger width
(Fig.12.5), unless otherwise
indicated on MEVA layout
drawings.
When using tie claws, the ties can
be placed at the outside edge of
the panels. For example; when
forming bulkheads, or directly
above the panels when forming
foundations.
Do not use ties as a means of
supporting bulkheads, or in any
other applications where shear
load is applied.

90° Corners
The MevaLite inside corner rigid
is provided with tie holes, and
consists of a aluminum frame with
a replaceable alkus face (Fig.14.1).
The length of each side is 1'
(Fig.14.2).
The MevaLite inside corner
elastic is designed to flex to allow
for easier stripping, and the alkus
face is replaceable (Fig.14.3). The
length of each side is 1' (Fig.14.4).
Steel rails or corner angles are
recommended to stiffen the corner
for concrete placement.
ML-alu fillers (1”, 2”, & 3”) are
used to make adjustments for
different wall thicknesses. Steel
rails may be required depending
on the filler/tie configuration (see
the “Fillers” section) and the wall
thickness.
MevaLite Outside Corners
The outside corners (Fig.14.5,
14.6) are connected to adjacent
panels with assembly locks, but
require more assembly locks than
the standard panel connections.
Steel rails may also be required.
See the "Standard Panels and
Outside Corners" section for
specific requirements.
There are two ways to form 90°
outside corners: with standard
panels and outside corners, or with
multi-purpose panels.

90° Corners
Multi-Purpose Panels
A multi-purpose panel (MPP)
can be used to form 90° outside
corners by connecting a standard
panel with column clamps. The
column clamp is secured with a
flange nut 100 or an articulated
flange nut 15/120. This method
can be used for wall thicknesses
from 6" to 13".
The offset hole pattern in the
MPP allows for wall thickness
changes in 1" increments.
Switching between odd and even
inch increments is accomplished
by simply rotating the MPP 180
degrees.
For wall thicknesses ≤9", the
maximum allowable concrete
pressure is 1350psf (Fig.17.1).
For wall thicknesses
>9" but ≤13", the maximum
allowable concrete pressure is
1100psf (Fig.17.2).
Two multi-purpose panels
connected with tensioning screws
may also be used to form 90°
outside corners for walls from 12"
to 15" thick (Fig.17.3 &17.4).
The maximum allowable concrete
pressure is 1350psf. Additional
locks are required at the panel
joints within 7' of the corner.
Both methods create a tight, rigid
connection.

MevaLite
Articulated Corners
Acute and obtuse angled corners
are formed using MevaLite
articulated inside and outside
corners. Steel rails are attached
to the multi-function profile with
flange screws at each tie hole
elevation (Fig.18.1 & 18.2). The
rails at the outside corner must
be attached to the panels with at
least two flange screws each, one
in the panel next to the AOC and
one in the adjacent panel. These
rails must also be bolted together
at their intersection with a flange
screw 18 and flange nut 100.
Flange screws shall be tightened
by turning with a hammer claw or
bar until snug, followed by a few
hammer blows.
If wood fillers are needed, the
panel profiles are connected using
Uni-assembly locks.
Side length of articulated outside
corner: 5”
Side length of articulated inside
