"Waffle-Crete" has evolved into a state-of-the-art structural precast
concrete building system.Years of working with the product has enabled
Advance Precast Ltd to develop the construction system far beyond
the original curtain-wall concept.
Utilization of modular design can give a functional and efficient
wall competitively priced far below other conventional precast systems.
"Waffle-Crete" is manufactured by Advance Precast Ltd. at our CSA
Certified Plant to C.S.A. specifications A23.4-09.
The versatility of the product seems to increase with each new project. By using an "adjustable-pan" steel forming system for the precasting, the panels can be made to dimensions that will be the most cost-effective for each project. With proper planning, future expansion can be accommodated. By considering the location of panel joints and panel sizes, in conjunction with detachable connections, entire walls can be relocated as a building is expanded over the years.
- Custom-made with window rough openings and cast-in door frames;
- Delivered direct to job site;
- Installed by our qualified inside crew;
- In most situations, panel extends to footing (below grade);
- Can have conduit cast-in for electrical and plumbing;
- Fully engineered C.S.A. approved panels
(light, coarse or striated)
(similar to acrylic stucco)
The individual finishes can be used alone,
but are often combined to produce some very handsome architectural
The lighter unit weight of "Waffle-Crete" panel permits the use
of smaller capacity crane equipment compared to the other forms
of conventional precast concrete. A precast building can greatly
reduce the amount of time needed to close in a building. At Advance
Precast Ltd there is an emphasis on making the structural connections
as simple as possible. That means more efficient use of sub-trades
and quicker completion. By standing the panels on strip footing,
the pouring of foundation walls is eliminated and the floor can
be poured under the shelter of a completed roof. All of these factors
often lead to an earlier occupancy by the tenant.
The "waffle" surface (usually to the interior of the building) allows
for the strapping of the interior walls with 1x4 wood or metal hat
channels. Either strapping can be attached quickly and solidly by
using a drilled hole (3/16" or 1/4" dia.) and "Zamac" pin fasteners.
The void areas of the panel can then be filled with R-20 Fiberglass
batt insulation, vapor barrier, and the interior dry walled. In
some instances, the building may be constructed with the "waffle"
surface to the exterior which will enable a concrete hard wall to
face the interior. This option is often used in northern climates
and the interior is finished with metal cladding. A "Waffle-Crete"
building has a very small amount of air infiltration. The precast
panel is very impermeable and all joints between panels are sealed
with a durable silicone or polyurethane caulking.
"Waffle-Crete" delivers all the advantages typical in concrete buildings
- long life with minimal maintenance.
The water tight nature of precast eliminates moisture absorption.
This provides a superb base for the application of cost effective
exterior latex paints. A sealed exposed aggregate finish tends to
be self-cleaning and has a very long service life. "Waffle-Crete"
is substantially lighter than standard concrete walls - making it
ideal for questionable soil conditions. The caulked joints will
absorb minor amounts of differential movement (and not result in
the zigzag cracking patterns so common with masonry block). If the
vertical movement of the joint becomes excessive, the caulking will
lose adhesion and the joint will need to be resealed.
A "Waffle-Crete" building will tend to appreciate in value much
faster than less substantial buildings.
