Professional Foundation Inspections | Video 004

Page Summary

• Professional Foundation Inspections identify visible and hidden warning signs such as stem wall cracks, floor fractures, efflorescence, concrete spalling, rebar oxidation, drainage issues, and soil movement around Arizona homes and commercial properties.
• Foundation Inspection work in Arizona often focuses on moisture intrusion, expansive soil behavior, roof runoff, driveway heaving, sidewalk displacement, settlement, subsidence, and concrete deterioration before repair planning begins.
• Concrete Repairman LLC provides experienced foundation evaluation, foundation estimation, stem wall repair planning, and concrete repair guidance for residential and commercial properties across Arizona.

Professional Foundation Inspections help Arizona property owners understand what is happening beneath and around their home or commercial building before damage becomes more expensive to correct. Cracks in stem walls, floors, driveways, sidewalks, exterior concrete, and interior finishes often point to larger movement patterns caused by soil moisture, poor drainage, rebar corrosion, settlement, subsidence, or foundation heave. At Concrete Repairman LLC, our inspection process looks beyond surface cracks and focuses on the conditions that create foundation movement, including water exposure, expansive soil, rusting reinforcement steel, concrete spalling, and structural separation. Led by James Belville, a master in concrete foundation repair, Concrete Repairman LLC brings third generation experience and more than 30 years of hands on foundation repair knowledge to homeowners and commercial property owners in Phoenix, Gilbert, and surrounding Arizona communities.

This foundation inspection video of a property in Gilbert, Arizona, shows numerous areas of damage to the foundation. This is an example of just how much damage can happen to your home if you ignore your home’s foundation. In this video, you can see the concrete just fall away as we inspect it, which is never a good sign.

Concrete Foundation Repair – Concrete Foundation Inspection

I’m in Gilbert, Arizona. The driveway has a lot of efflorescence, which is the darkening and the white. The whiteness is the efflorescence or salt deposit left behind, and the driveway is cracked right here in heaved tilted down from the saturation of soil over in this geographic area, which is raised this corner of this slab at that juncture. There are exterior cracks that look like they’ve already been identified, with blue tape on both corners. Assessing the movement of the sidewalk as well as second-story windows right below the windows is starting to separate right there, and this garage is separate from the house, and it’s wanting to pull this way, indicating movement here on the stem wall Foundation area. The entry walk is heaved, I’ve got a large trip hazard right there this sidewalk is down approximately three inches.

Various cracks and fractures in the corners of the door windows have some undermining here from a sense of moisture, or it could be a leak stem wall that needs to be waterproofed. A vertical fracture in that stem wall shows the movement of this side of the stem wall slightly going down. It’s articulating. Do you have the fractures next to the window and various areas through the wall? That crack fracture right there is the oxidized rebar. Once the moisture reaches the reinforcement number four bar a half inch in the stem wall, it’s going to oxidize and expand up to five times its diameter in size, and it’s going to break out the side of the stem wall like this, and you can see the J bolt right there. This is j bolt holding down the bottom plate of this stem wall that’s behind here. These are remnants of the half-inch rebar, and I believe I just moved the camera around here a little bit so you can see what I’m doing: just destroying the stem wall with my knife and rebars right here.

It’s oxidized, and it’s coming off in little pieces. The sense of moisture causes this in this area where the paint has been delaminated off this surface by water, and evaporation of water, leaving behind the efflorescence, will separate the paint from the stem wall before the paint falls off. It degrates the surface of this concrete here. That’s why you see exposed aggregate. There are various cracks, horizontal and vertical, throughout the exterior of this home. There’s a very large crack fracture right there, and there are settling cracks; this one is vertical, which shows that this stem wall is articulating. It’s moving because of the moisture around the stem wall. It has to break in fracture because of all of the stress that’s pushing down on this foundation, and it’s not stable enough to hold it, so it has to relieve itself by cracking and fracturing. Walk around the other side, right? There is a hurricane strap. Hurricane straps are designed to hold this corner of the building down securely into the stem wall, which is typical of rusting, oxidizing, expanding, and cracking the concrete.

I can’t see it here, but the same things are happening back in the corner. We have spalling all along this whole side, the paints coming off, which is the first phase the paint comes off spalled concrete, and then the moisture reaches the steel rebar inside, oxidizing and expanding, causing cracks on the exterior. The slab has cracks throughout the entire wall and horizontal and vertical corners of windows, and moisture comes from the roof. The roof water landing here in this area seems to be puddling, but it also has to do with soil types and how much moisture will be retained. This side of the stem wall in the backyard also has some spalling but needs to be waterproofed. The entire home needs waterproofing. There are various cracks and fractures on the exterior of the stucco, and this whole site needs to be waterproofed as well. We did have a recent rain, and it seems like in this geographic area where a lot of water pools along with the other side in the front yard.

What a Foundation Inspection Looks For

A Foundation Inspection should begin with visible evidence around the structure. The exterior often provides the clearest early signs because stem walls, driveways, sidewalks, patios, garage slabs, and drainage areas are exposed to water, heat, soil pressure, and weather cycles. In Arizona, foundation concerns frequently appear around the base of the building where moisture contacts concrete and reinforcement steel.

Inspectors look for horizontal cracks, vertical cracks, diagonal cracks, spalling concrete, exposed steel, flaking paint, efflorescence, and separation between concrete sections. Efflorescence appears as white mineral staining and can indicate that moisture is moving through concrete. When water carries salts to the surface, it may leave visible deposits that help identify ongoing moisture exposure. If this moisture reaches reinforcing steel, corrosion can expand the steel and push against the surrounding concrete.

Stem wall cracking is especially important in Arizona foundation evaluations. A stem wall is the concrete wall that connects the footing to the structure above. When rebar inside the stem wall rusts, the steel can expand and create internal pressure. This pressure can fracture the concrete, cause horizontal cracking, and lead to spalling. Once the concrete begins to separate, the problem usually continues unless the moisture source and damaged material are addressed.

Arizona Soil, Moisture, and Foundation Movement

Arizona foundations are affected by soil and water behavior. Although the climate is dry for much of the year, foundation problems often develop when water is concentrated in the wrong place. Roof runoff, irrigation overspray, leaking hose bibs, poor drainage, planter beds, pooling water, and improperly sloped concrete can place moisture directly against the foundation.

When soil near a foundation becomes saturated, it may expand and lift concrete. When the soil dries, it can shrink and create voids or uneven support. This cycle can contribute to foundation heave, settlement, subsidence, slab cracking, and movement in surrounding flatwork. Driveways and sidewalks may tilt, lift, drop, or separate from adjoining concrete. These changes can create trip hazards and can signal that water and soil pressure are affecting more than the visible surface.

A Professional Foundation Inspection evaluates how water moves around the property. Inspectors may look at roof drainage patterns, downspout discharge areas, grading, hardscape slopes, exposed soil, planters, concrete joints, and areas where water may collect. Understanding moisture patterns is especially important in communities such as Phoenix, Gilbert, Mesa, Chandler, Scottsdale, Tempe, Peoria, Glendale, and other Arizona service areas where soil conditions and property layouts vary by neighborhood.

Stem Wall Cracks and Rebar Oxidation

Stem wall damage is one of the most important conditions reviewed during a foundation inspection. Many Arizona homes and commercial buildings use reinforced concrete stem walls. The steel reinforcement inside the concrete provides strength, but it can become vulnerable when moisture reaches it. Once steel starts to oxidize, rust expansion can place pressure on the concrete from the inside.

This type of pressure can create long horizontal cracks, concrete separation, spalling, and visible rust staining. In some cases, the damaged concrete may break away and expose the reinforcing bar. The concern is not only appearance. A damaged stem wall can continue to deteriorate if corrosion remains active and moisture keeps entering the concrete.

Professional Foundation Inspections look for clues such as horizontal stem wall cracking, vertical breaks, corner separation, delaminated paint, exposed steel, rust colored staining, and concrete flaking near the base of the structure. These conditions help determine whether a simple surface repair is insufficient and whether a more complete stem wall repair process is needed.

When to Book a Professional Foundation Inspection

Property owners should consider booking a Professional Foundation Inspection when they see cracks spreading, concrete lifting, sidewalks dropping, exterior stem wall damage, rust staining, white mineral deposits, water pooling near the building, sloping floors, doors sticking, or previous repairs failing. It is also wise to request an inspection before major remodeling, property purchase, sale preparation, or when a foundation estimate is needed for budgeting.

Waiting can allow moisture, corrosion, and soil movement to continue. Early inspection can help property owners determine whether the issue is minor, moderate, or urgent. It can also prevent unnecessary repairs by identifying the actual cause of the damage before work begins.

A clear next step is simple. Call Concrete Repairman LLC to schedule a Foundation Inspection, book a foundation evaluation, request a repair quote, or ask for an audit of visible concrete and foundation concerns. A professional assessment gives you the information needed to protect the structure and plan repairs with confidence.
