In Waco, foundation trouble is part of life. The black clay under many homes swells with rain and shrinks in drought. A house sitting on it moves. You may see a crack over a door, a floor that is no longer level, a gap at the window or a door that sticks every summer.
Waco Concrete handles concrete foundation repair in Waco TX, including slab edge repair, crack repair, concrete leveling and drainage fixes. We are locally owned, we look at the cause first and we give a free written estimate.
Signs that your foundation needs repair
Not every crack is a problem. Small hairline cracks in concrete are common as it cures. But some signs are worth a call. Look for cracks wider than a quarter inch, cracks that run across a whole slab or a brick wall in a stair step pattern, and doors or windows that no longer close.
Floors that slope, gaps between the wall and the floor and tile that cracks are also signs. Write down the date you noticed each one and take photos. That helps us see whether it is moving.
- Cracks wider than a quarter inch
- Stair step cracks in brick or block
- Doors and windows that stick or will not latch
- Floors that slope or feel uneven

Why foundations move on Waco clay
Clay soil holds water. When it rains, the clay swells and pushes up. In a dry summer, it shrinks and pulls away from the foundation, and the slab sags into the gaps. This cycle repeats every year, and it is not even across the whole house.
Water makes it worse. Leaking pipes, bad grading, clogged gutters and sprinklers pointed at the wall can soak one side of a foundation while the other side stays dry. Tree roots can pull water out of the soil near the house.

How we approach foundation repair in Waco TX
We start by looking. We check the cracks, measure how far things have moved and study the grading and drainage. Then we explain what we see in plain words. Some problems need only a drainage fix and a crack repair. Others need slab edge work, concrete leveling or a bigger plan.
We do concrete work. If we see signs that call for a structural engineer or a pier and beam specialist, we tell you so. We would rather give you honest advice than sell a repair that will not last. See also concrete leveling and concrete repair.

Foundation repair cost, timing and next steps
Cost depends on the size of the problem, the access and the repair method. A drainage fix and a crack repair cost far less than major lifting work. Most small repairs take a day or two. We give you the price and the steps in writing.
Call us any day from 5 AM to 10 PM or use the contact page. Send photos of the cracks if you can.
Foundation Repair questions answered
How do I know if my foundation has a real problem?
Look for patterns, not single marks. A hairline crack that has not changed in years is usually not a concern. Cracks that are wider than a quarter inch, that grow, or that run in a stair step pattern through brick are more serious. Doors and windows that stick, floors that slope and gaps along walls are also warning signs.
A good test is time. Mark the end of a crack with a pencil and the date, then check it every few weeks. If it grows, call us. We can come out, look at the crack, check the grading and drainage and tell you what we think. If the problem looks structural, we will say so and suggest the right expert.
Take a few photos of any cracks and send them with your call. Photos help us plan foundation repair in Waco TX before we visit. Ask for photos of any work you approve, so you have a record.
What causes foundation problems in Waco?
The main cause is the soil. Much of Waco sits on expansive black clay. It swells when wet and shrinks when dry, and the foundation rides along with it. A long dry spell followed by a heavy rain is hard on any slab. Bad drainage, leaking plumbing and big trees near the house can make it worse.
We look at all of these. Often, the first fix is to control the water. Extend downspouts, fix the grade so water runs away from the house, repair leaks and keep sprinklers from soaking the foundation edge. Then we repair the damage that has already happened. Without the drainage fix, the problem usually returns.
Keep a short log of where and when problems show up. Foundation repair works best when we know how the movement changes with the weather. Keep a simple log of dates and photos, because a slow change over a season tells us much more than a single visit can.
Can concrete leveling fix a sunken slab?
Often, yes. Concrete leveling lifts a sunken slab by filling the empty space under it. It works well on patios, garage aprons, walks and some slab edges that have dropped in one piece. It does not work when the slab is badly broken, or when the soil is still moving quickly.
We check the slab and the ground, then tell you if lifting will last. If it will, leveling usually costs far less than tearing out and pouring again. Read more on our concrete leveling page. If the problem is a house foundation, we explain which parts we can help with and which need a structural specialist.
Water control is the most important step in foundation repair, so we always look at gutters, slopes and sprinklers first. If your gutters empty near the wall, fixing that is often the cheapest step, and it can slow the movement of the soil beside your foundation.
How much does foundation repair cost in Waco TX?
The price varies a lot. A small crack repair with a drainage fix costs far less than lifting and shoring a whole house. The cost depends on the size of the problem, how much concrete is involved, how easy the area is to reach and what method is needed. Prices also differ between companies, so get a written estimate.
We give a free written estimate after we look at your foundation. We list what we will do and what we will not do. If we see something outside our work, we say so clearly. Be careful with any company that offers a price over the phone without seeing the foundation, because every house and every lot is different.
Always get the estimate in writing. A good foundation repair plan should list each step and what is not included. We also tell you what to expect after the repair, so you can watch for new cracks and call us if something changes.
Will watering my foundation help prevent cracks?
You may have heard this advice, and in some cases a slow, even soaking around a foundation in a dry spell can reduce shrinking. But it must be done carefully. Too much water in one spot can make the soil soft and cause new problems. Soaker hoses should sit a foot or two from the slab, and the watering should be even on all sides.
The better long term step is good drainage. Keep gutters clean, send downspouts well away from the house and make sure the ground slopes away from the walls. We can look at your yard and suggest a simple plan. This is a low cost way to protect your foundation and your concrete.
A steady, even watering plan is a small habit that protects a slab, but it is no substitute for fixing the drainage first. Always ask who will do the work and who stands behind it, since good foundation advice should come with a clear name and a clear promise.
Should I fix cracks in my slab or wait?
Do not wait too long. Small cracks let water in, and water makes cracks grow. Sealing a crack early can keep the problem small. Cracks that are growing, that show height differences between the two sides, or that let in water should be looked at soon.
We can fill and seal cracks, repair broken edges and level sunken sections. If the crack points to deeper movement, we say so, and we plan for the cause. See concrete repair and slab foundations. A quick visit costs nothing, and it can save you from a larger repair bill in a year or two.
If your foundation repair needs go beyond concrete work, we will say so and help you find the right specialist for the next step. A quick note to your insurance agent or your builder may also help, and we can supply photos and a written description of the work.
