Reducing emissions with CO² cured-concrete

A new cement block manufacturing process developed by an American company named Solidia Technologies® produces 40% fewer emissions during manufacturing than conventional concrete, resulting in a dramatically lower environmental footprint. Solidia’s concrete is formulated with less lime and is cured at lower temperature...

Finishing concrete floors with silicate densifiers

Polished concrete floors are extremely durable and non-toxic; silicate-based densifiers keep them that way and make it a great start to safe indoor-air quality in a home. This is an excellent flooring option for anyone with chemical sensitivities who wants a beautiful and durable eco-friendly floor in their passive sol...

Gabion Walls - what is a gabion cage & how to build with them?

Gabion walls are retaining walls built by stacking stone in a gabion cage or gabion basket that can serve many purposes but are most often used to create tiered or leveled ground in gardens.  They are rectangular baskets of metallic lattice filled with stones and their origin dates back to war times when they were erec...

Low-carbon concrete by CarbonCure Canada - lowering the carbon footprint of buildings

Low-carbon concrete - "green" cement at last?  One of the most essential and commonly-used building materials in home construction, commercial buildings and city infrastructure is concrete, which has an extremely high carbon footprint, with cement production accounting for 7% of global carbon emission. This problem is...

Slab on grade or a foundation and basement?

Slab-on-grade vs foundation and crawlspace or basement

Is an insulated slab on grade the best foundation choice? Or is a basement better? Traditionally, home construction often starts with a concrete basement foundation - But is that the best choice?  The first factors to consider when designing the foundation system for a home are lot size and soil conditions. When space ...

How wood structures compare to steel and concrete for Carbon Footprint

Wood, steel and concrete each have specific structural advantages, each with their own characteristics. The following is a life-cycle comparison conducted by the Athena Sustainable Materials Institute (ASMI) of the materials only, and does not include any considerations of how they each affect thermal performance, vapo...

Insulation and soundproofing

Properly insulating basements and concrete slab floors

  Insulating a basement is a great idea if it wasn't insulated when built, as before we began insulating foundation walls and below slabs (see slab on grade), it was generally estimated that basement heat loss accounted for about 1/3 of the total heat loss of a house. It is likely that such an abysmal starting place ma...

how to build a slab-on-grade on standard soil

There are many ways to build a slab-on-grade (or frost-protected shallow foundation), the following is a step-by-step walk though of a thickened-edge slab floor we built. XPS or EPS rigid foam is typically used under concrete slab floors, in this case we used mineral fiber insulation. Note: our mineral wool was provide...

Insulated Radiant Floor ICF Foam Forms Heated with Air
Delivery: radiant, forced-air and decentralized

Air-heated radiant floor slab foam forming systems

Radiant heating systems are very common in concrete floors now because they provide a very balanced and comfortable distribution of heat. Those systems are most commonly hydronic, meaning heated liquid is pumped through tubing in the concrete which then radiates that heat into the house. View the slab on grade foam for...
