That is, heat is liberated during both the setting & hardening process of the concrete. The concrete expands as the temperature rises, & restraint against contraction on subsequent cooling, unless properly controlled, leads to cracking. The cracks that form usually pose a durability problem, ...

They are energy efficient because they retain heat so well.Fiberglass hot tubs are smooth, low maintenance, and come in various colors. However, people with asthma may have problems when it needs to be recoated (every five years), and fibers are released into the air. ...
Concrete$60–$140$100 In addition to the material, you’ll need to decide if a prefabricated (pre-fit) or custom bathroom vanity works best for your bathroom design. Pre-fit countertops are built to standard dimensions that work for most bathroom layouts. They provide an easy installation and...
Nobody expects a natural disaster to strike. Neither does anyone know the impact it can have on life. The following measures can save your life in an emergency. Typhoon Typhoons occur in the northwestern Pacific Ocean, particularly in exposed regions like the Caroline Islands, the Philippines, ...

From selecting sustainable materials (bamboo, concrete or reclaimed tile) to installing eco-friendly features (a timer on your vent fan or a water-conserving shower head), small changes can make a big difference over time.DIY shower remodel vs hiring a professional...
Four decades ago, less than 5 percent of American were cremated when they died. Now that figure stands at nearly half. This is how cremation actually works, and what happens to a culture when its attitude about how to memorialize the dead undergoes a rev
and the forms make it easier to attach interior and exterior sheathing materials. Concrete reduces exterior noise by as much as two-thirds. It's also less attractive to insects and rodents. Concrete creates a substantial thermal mass, so that the house will retain both heat and cool temperature...
