Are waffle pod slabs good?

Are waffle pod slabs good?

They work perfectly well on non-reactive sites, slightly reactive clay sites and some moderately reactive clay sites. Waffle slabs are not recommended for use on highly reactive clay sites (Class H1 and H2) because the requirements for good drainage will be nearly impossible to achieve.

How do you make a waffle pod slab?

How to construct waffle raft slabs

1. Clear and level site.
2. Do under slab work. termite treatment. plumbing.
3. Lay plastic sheeting and edge formwork.
4. Lay pods in a grid pattern and place spacers in between.
5. Place reinforcement steel between and mesh on top of pods elevated by plastic “bar chairs” or similar.
6. Pour concrete.

Are waffle pod slabs cheaper?

Waffle pod slabs are innovative because they use polystyrene void formers rated for efficient thermal insulation. These factors generally mean that a waffle pod slab will be significantly cheaper than a regular concrete raft slab.

What are the benefits of a waffle pod slab?

Benefits of Using Waffle Pod Slabs

• They Are Cost-Effective. These slabs are cost-effective in terms of preparation and during the building process.
• Simplified Construction Process.
• Strong Structural Stability.
• Improves Safety.
• Makes Other Construction Services Simpler.
• Environmentally Friendly.

Do waffle pod slabs need Piers?

The slabs are typically piered with either mass concrete augured piers or screw piles. However, it may be possible to not have piers, in particular if the building is to be constructed with a light weight clad frame, rather than brick veneer or full brick construction.

What is waffle pod concrete slab?

WHAT ARE WAFFLE PODS? This is where the concrete is sitting on (and around) a series of boxes (or Pods) set out in a grid pattern. Think of a waffle pod as a raft lying flat above your soil.

How does a waffle pod slab work?

When concrete is poured onto the waffle pod assembly, the spaces between each pod become super-strong reinforced ribs. These ribs give a waffle pod slab stiffness and consistency that ensures a solid basis for a new home.

Do waffle pod slabs have footings?

WAFFLE SLABS A waffle slab is a reinforced concrete footing and slab system, usually around 80mm thick, that is constructed directly on the ground. Waffle slabs consist of an edge beam (perimeter footing) and selectively spaced internal beams that run each way.

What is a waffle pod concrete slab?

What is the difference between ribbed slab and waffle slab?

Ribbed slabs are made up of wide band beams running between columns with narrow ribs spanning the orthogonal direction. Normally the ribs and the beams are the same depth. Waffle slabs have a thin topping slab and narrow ribs spanning in both directions between column heads or band beams.

How to build a waffle pod slab built-pod sales?

1. Ensure the building site is as flat as possible. If necessary, cut and fill the site or fill the site with sand until a level surface is obtained. If uncompacted fill is present, you should refer to the engineer’s report for pier details. 2. Lay out the plumbing according to your plans, and then carry out white ant treatment.

How is a waffle slab supported in a church?

Waffle slabs are supported on beams or columns, where the support zones are made to be uniformly thick. A church building has a square grid of 7.5m x 7.5m of waffle slab, and is to support an imposed load of 5 kN/m 2, design an interior panel of the waffle slab, and a supporting beam. f ck = 30 Mpa, f yk = 500 Mpa.

What’s the difference between concrete and prefabricated waffles?

The prefabricated waffle slab usually costs higher than the other two options. The construction process involves a building system of concrete slabs that are shored up by columns.

What should the top of a waffle slab look like?

• This makes a waffle slab perfect for large flat areas like foundations or floors.  Appearance : • The top of a waffle slab is generally smooth, like a traditional building surface, but the underside has a shape reminiscent of a waffle. • Straight lines run the entire width and length of the slab, generally raised several inches from the surface.
