Like billiards, with acoustics it's all about the angles

This sand-and-water model confirms mathematical predictions about how groundwater moves through soil

For historical work, joist hangers won't cut it, so turn to traditional woodworking joinery

Two words: lag bolts?

Materials absorb or reflect sound, but not all frequencies are the same

Closed-cell spray foam in a two-part froth pack is a fast and effective way to eliminate thermal bridges and air leaks in building assemblies

Replacing a toilet is a task most remodelers will have to do much more than they want to, so get it right the first time

How steel reinforcement makes concrete stringer: by giving it tensile strength. And how to boost tensile strength with prestressing or post-tensioning

Mesh sheeting creates a drainage space between the siding and weather-resistive barrier (WRB) allowing walls to dry much faster which makes them last much longer.

Everything there is to know (well, almost) about blower door testing with a few engineer-y jokes along the way.

How building materials absorb, reflect, and transmit sound waves

Protect the edges from sideways rain, and overlap like you've done it before!

Flashing, overlapping, and sealing layers keeps the outside out and the inside in

Overspray will get everywhere, so make sure the booth is contained, and make sure your tools are out of the booth.

The Tyvek weather-resistive barrier can be a water barrier and an air barrier, but it is NOT a vapor barrier

Furring and foam on the INSIDE for better walls in really cold places.
