One of the ways to achieve a high quality concrete pavement is by having a proper joint spacing design. An effective jointing system can control the location and geometry of transverse and longitudinal cracking. Carefully designed joints can help relieve stresses which result in cracks. Stresses ...
This method of creating joints is typically used for more narrow concrete surfaces such as sidewalks. Although one of these joints made from a joint trowel doesn't extend completely through the thickness of the slab, there is enough space in the top part of the joint to absorb most of the...
Form joints accurately to detail and in locations shown on the drawings. If modifications to any joint design or location are necessary on site, agree revisions with the engineer before proceeding. Do not allow concrete to enter any gaps or voids in the formwork or to render the movement ...
They just need to be long enough to catch a bit of the poplar, and don’t counter sink them. Don’t worry if the boards aren’t perfectly level, it’s meant to look like reclaimed wood, so it shouldn’t be perfect! Here is the wood countertop after all the wood planks were put ...
It is as turnkey as a swing set can get with no need to stain or paint the swing set before use. It is free-standing and does not require you to put a concrete anchor into the ground. This means that if you later decide to remove the swing set when your children have outgrown it...
I stopped by Tuesday evening on the way to an event in Navy Yard, appreciating the Russell Building’s handsome Beaux-Arts architecture, then attached our reasonably-priced purchase to the flagpole on our front porch Wednesday morning. Sometime that afternoon or evening, a gust of wind put ...
Install deck boards straight or diagonally and in herringbone or parquet style. In each case, however, stagger the butt joints to fall on different joists. Notch the deck boards as needed to fit them around any posts. At the edge of the deck, let the boards run ragged, and once you’re...
Installing the concrete at the specified thickness and then laser screeding and finishing the surface to ensure that the floor meets the specified flatness and levelness requirements. Cutting contraction joints in the slab at the specified depth and spacing, using an early-entry saw that won't mar...
A tongue-in-cheek but semi-serious walker's guide to coping with extreme heat and humidity. Includes photos and description of Doha, Qatar, as only seen on foot.
in the production of pervious concrete.The main function of permeable concrete reinforcement is to make the stone fully wrapped by the cement slurry, keep the slurry still, improve the bond of permeable concrete, and lay a good foundation for the improvement of the strength of permeable co...
