Dear Jim: I am thinking of building one of those concrete/foam block houses for efficiency, security and strength. Since concrete feels so cold, is it really energy efficient and will I be limited on ...

People don’t believe Ray Hartzell when he says he will spend less than $400 this winter to heat his newly built 2,800-square-foot home in Upper Mount Bethel Township. After all, Hartzell’s ...

The latest 3D printing application? Forming concrete. That’s according to a team at ETH Zurich who claims that construction with foam forms cuts concrete usage up to 70%. It also offers improved ...

Q: We recently noticed that part of the concrete walkway connecting our driveway with the front door has begun to tilt slightly in one direction. Is there anything we can do to make it level again ...

The only clue to the unusual construction of the walls is the deep windowsills trimmed in red birch. Siding is attached to the exterior foam blocks, and sheetrock to the interior foam blocks, by ...

For decades, concrete walls and foundations were made the same way. Plywood or plain boards are built into forms that contain steel reinforcing bars (rebar) and into which wet concrete is poured. When ...

Watch this high-density polyurethane foam raise concrete slabs thanks to the magic of physics. The foam, called PolyLEVEL, is applied through a hole drilled in the concrete, expanding under the ...

The desire for new and different combined with a willingness to continually push toward the edge of possibility are frequently the fundamental ingredients of architectural innovation. What architects ...

The construction industry is highly unsustainable. In fact, 7% of global CO2 emissions result from cement production alone. In an effort to cut down construction-related carbon emissions, researchers ...

An curved arrow pointing right. Mudjacking or slabjacking is a technique used to raise and level concrete. Foundation Works has developed a new foam technique, Polylevel, that can raise thousands of ...
