Learn how to builder faster, better and more profitably with Logix.

Placing the 1st Logix corner

The Basics

 Logix ICFs blocks are delivered to site as pre-formed solid blocks, ready to stack together "Lego" style into the walls of your building. At this stage each block will build about 0.5m2 of wall, and weighs only 3-6 kgs  so they go together quickly.

As the wall goes up horizontal rebars are installed into the clips in the plastic webs, where required. A lot of domestic buildings can exceed the structural requirements of the building regulations without the need for rebar, but it's nice to know, when required its easy to install.  
Windows and doors are formed to the shape required by cutting the blocks with a hand saw, and installing "End Caps" and "Cavity Closures", then bracing with timber.

Joist hangers for timber floors are installed, or the blocks cut ready to accept concrete floors or RSJs, and ducts installed for services which will pass through the wall all before the wall is filled with concrete. 

Also before pouring the concrete the walls are braced, on one side, to keep them straight and plumb.

Pouring Concrete

The Concrete Pour

The concrete is usually best placed via a concrete pump, which allows controlled placement into the walls. The concrete is placed in layers and compacted, as it is placed before starting another lap of the building. This allows walls up to 3m high to be filled in one operation, making the whole floor of the building to be built as a monolithic air-tight structure.

Small sections of wall can be filled direct from the mixer, or barrow at low level, or via tele-handler at high level. On larger sites a crane and skip is a useful option.

The concrete will have enough early strength to allow work on the building to continue the day after the pour. 

Remember...

building with Logix ICFs is pretty straight forward, once you know what you are doing and we have worked with lots of successful self builders who are new to ICFs, but working with concrete should not be taken lightly. 

That is why all builders and self builders, must complete a comprehensive Logix installer training course. the course will not only get you up to speed before you start on site, but includes onsite support and assistance during the concrete pour.

Structural Design - the basics

Every Logix building needs to be designed properly, but a competent engineer, and if you don't have one already we can introduce you to engineers we work with regularly. 

Fortunately this needn't be a complex process. The concrete is a standard 6" Logix ICF can be shown to have more lateral stability, i.e. wind resistance, than 300mm wide masonry cavity wall. That means if you could build it from from unreinforced concrete blocks you can build it using an unreinforced Logix wall.

While traditional concrete walls need reinforcing, the Logix insulation layer means the concrete cures in a perfect, moist, warm environment. It won't dry out too quickly meaning that we don't need to reinforce for anti-crack purposes.

All projects will require some reinforcement , if only to create lintels. By adding rebar above window and door openings before pouring the concrete lintels are easily created. 

If you building double high structures, retaining walls or multi storey projects the rebar is easily and quickly built into the walls, held in place by the Logix webs, without the need to tie it together.

Thanks to the strength of the concrete Logix walls can work with any  floor construction of your choice, timber, pre-cast or cast in-situ concrete floors. It is like having a pad stone everywhere in the  wall, so supporting RSJs is simple.
