Concrete Pouring in Gilbert, AZ

We start with a hands-on inspection — sounding bricks for hollows, probing mortar with a pick to test hardness, photographing crack patterns to distinguish settlement from thermal movement. Failed mortar is cut out to a depth of at least 2× joint width (typically 5/8"–3/4") with a tuck-point grinder, joints are flushed clean, and new mortar is matched to the original in compressive strength, color, and texture. Replacement bricks are sourced from reclaimed yards when possible; visible elevations get the best matches. Sealers are applied only after mortar fully cures (28 days minimum) and only breathable formulations so trapped moisture can escape.

Breathable masonry sealers can help reduce water absorption while allowing moisture inside the wall to escape. Sealers are not appropriate for every situation, and non-breathable coatings can trap moisture and cause damage. Choosing the right product depends on the type of masonry and its exposure.

Concrete continues to gain strength for weeks after it is placed, but only if it retains enough moisture to cure properly. Keeping the surface moist, using curing compounds or covering the slab helps prevent premature drying. Proper curing reduces cracking and improves strength and durability, which is especially important in Arizona's dry climate.

Many Arizona homeowners add concrete pads beside their homes for RVs, boats or extra parking. These slabs need to support heavy loads, so they require proper thickness and reinforcement. HOA rules and setbacks may also affect where RV pads can be located and how they must be screened.

Concrete naturally shrinks as it cures, and some cracking is normal. Control joints, which are deliberately placed grooves, encourage cracks to form in straight lines at predetermined locations rather than randomly across the surface. Correct spacing and depth of control joints help concrete crack in a controlled, less noticeable way.

If a wall is leaning significantly, has extensive cracking or was built with an inadequate footing, rebuilding may be safer and more cost-effective than repeated repairs. Rebuilding allows a proper footing and reinforcement to be installed, giving the wall a much longer service life.

Many block walls are painted or coated to match a home's exterior. Over time, the finish fades and peels in Arizona's sun. Repainting requires cleaning, repairing cracks and using coatings formulated for masonry. A well-applied finish protects the wall and improves its appearance.

Spalling occurs when the face of a brick or block flakes, chips or breaks away. It is often caused by moisture moving through the masonry, combined with salt crystallisation or temperature changes. Repairing spalled units may involve replacing individual bricks or blocks and addressing the moisture source that caused the damage in the first place.

Minor cracks and surface wear can sometimes be repaired or resurfaced, but slabs with significant settlement, heaving or extensive cracking may need replacement. Evaluating the cause of damage determines whether repair will last.

Arizona's heat creates particular challenges for concrete. High temperatures, low humidity and wind cause water to evaporate quickly from fresh concrete, which can lead to rapid setting, surface cracking and reduced strength. Pouring early in the morning, keeping materials cool, using appropriate admixtures and protecting the surface from rapid drying help produce durable concrete in hot conditions.

A leaning or tilting block wall usually signals a problem below ground. Inadequate footings, soil erosion, expansive soils, tree roots or water collecting at the base can all cause movement, as can soil or landscaping piled against one side. A leaning wall can become dangerous, particularly if it continues to move. Evaluating the cause determines whether the wall can be stabilised or needs to be rebuilt.

Steel reinforcing bar, wire mesh and fibres can be added to concrete to improve its performance. Reinforcement helps hold cracks together and increases resistance to loads, which is particularly important for driveways and slabs that support vehicles. The right reinforcement depends on the slab's purpose and thickness.

The ground beneath concrete must be properly prepared to support the slab evenly. Removing organic material, compacting soil and adding a suitable base layer help prevent settlement and cracking. Poorly prepared ground is one of the most common causes of concrete failure, regardless of how well the concrete itself is placed.

Every pour starts with subgrade prep — strip topsoil, compact to 95% Proctor, and place a 4" aggregate base course for driveways and slabs. Forms are set to grade with proper slope for drainage (1/4" per foot minimum on patios). Reinforcement: #4 rebar on 18" centers for driveways, welded wire mesh for patios. Concrete spec: 3,000 psi minimum residential, 3,500–4,000 psi for driveways and structural slabs, Type II low-alkali cement, 4–6% air entrainment. Hot-weather pours use chilled water, retarding admixture, and 4–6 AM placement. Curing follows ACI 308 — wet cure for 7 days or apply ASTM C309 curing compound. Saw-cut control joints within 8–12 hours of placement at 24× slab thickness spacing.
