Prevention is cheaper than repair - protect your foundation with proper drainage
The single most effective thing you can do to prevent foundation problems is manage water around your home. Here are eight practical tips that Hill Country homeowners can implement today.
The ground around your foundation should slope away from the house at a rate of at least 6 inches over the first 10 feet. Over time, soil settles and this grade can flatten or even reverse, directing water toward your foundation instead of away from it.
What to do: Walk your perimeter after rain. If you see water pooling within 3 feet of your foundation, you need to regrade.
A single downspout can dump over 1,000 gallons of water next to your foundation during a heavy Hill Country rain. That's the equivalent of leaving a garden hose running against your house for hours.
What to do: Clean gutters twice a year (after cedar pollen season and after fall leaves). Extend downspouts at least 5 feet from the foundation using extensions or splash blocks.
This seems counterintuitive, but during extended drought the clay soil around your foundation shrinks dramatically. Maintaining some moisture prevents the most extreme contraction.
What to do: Place a soaker hose 12-18 inches from your foundation and run it 15-20 minutes every other day during drought. You're not trying to saturate the soil, just prevent extreme drying.
A mature live oak can pull 50-100+ gallons of water from the soil daily. If that tree is within 20 feet of your foundation, it's pulling moisture from beneath your home.
What to do: You don't need to remove trees, but install root barriers between large trees and your foundation if they're within 15-20 feet. Water the area between the tree and foundation during drought.
A slab leak can saturate the soil under one section of your foundation, causing it to heave upward while the rest stays put. This differential movement is extremely damaging.
What to do: Watch your water bill for unexplained increases. If you hear running water when nothing is on, or see warm spots on your slab floor, call a plumber immediately.
Irrigation systems that water heavily on one side of the house while the other side stays dry create the exact uneven moisture conditions that cause differential settling.
What to do: Ensure irrigation provides relatively even coverage around all sides of your foundation. Avoid sprinklers that spray directly against the foundation wall.
If you have chronic water pooling in specific areas near your foundation, surface grading alone may not solve the problem. A French drain collects subsurface water and redirects it away from the house.
What to do: If you consistently see saturated soil against your foundation after rain, despite proper grading, consult with a drainage specialist about a French drain system.
The Hill Country gets intense rainfall events that can change drainage patterns overnight. Erosion can redirect water flow, saturate previously dry areas, or undermine your grading.
What to do: After any heavy rain, walk your property and look for new erosion channels, pooling water, saturated areas near the foundation, or gutter overflow.
If you're already seeing signs of foundation problems despite good drainage, the damage may have accumulated over years before you took action. Drainage improvements are still important to prevent further damage, but you may also need foundation repair.
