When to install a gate in Austin weather
The sky says dry all week, and then a few inches of rain fall in an hour and every open post hole in the neighborhood is a pond. The breakdown sitting on gate installation austin three word wednesday keeps a weather calendar for this reason: gate installation in Austin, TX follows the seasons, and the weather decides what gets dug, poured and hung. Flash floods are normal in this part of the Texas Hill Country, and crews plan around them.
Summer heat and the pour
In the long Austin summer, concrete in an open hole dries from the outside before it has cured through. Hot clay and hot rock pull water out of the mix at the walls. Crews pour early, wet the sides of the hole, and cover the top of the footing with a sheet or damp burlap. A footing that dries too fast gets weak and cracks at the top, right where the galvanized steel post enters it, and a cracked collar lets water reach the weld at the base plate.
When a hole fills with rain
A hole that has taken on water is pumped or bailed, and the sides are checked for slumping. Clay that has soaked and slid into the hole gets cut back to firm ground. Standing water in the bottom is never poured over, because the mix gets diluted and sets soft. Near Barton Springs and Lady Bird Lake, where the ground stays damp, crews may wait a day or two rather than mix concrete into a wet hole.
How long before a gate goes on
A concrete footing needs several days before it takes any load, and longer in cool, damp weather. Hanging a heavy steel swing gate on a footing that has not cured enough pushes the post out of plumb. A light aluminum picket leaf puts less load on the post, but the same patience applies. The crew presses a thumbnail into the concrete at the edge, checks for hardness, and keeps braces in place until the footing is ready.
Dry cracked clay
After weeks without rain the clay shrinks and cracks wide open, which is hard on digging and on any footing already in the ground. A dry hole stays open and clean, which helps. The cracks, though, carry water straight to the base of any footing the first time it rains. Setting posts in the dry season and finishing the top edge of the concrete with a sloped crown keeps that water away.
Picking the right window
Mild stretches in fall and spring give the best mix of workable ground and steady curing. Mueller, Bouldin Creek and the rest of the east side clay can be dug in any season, but it behaves best when it is neither baked hard nor soaked soft, and gates hung then stay square longer.
