Concrete Pouring in Fountain Hills, AZ

Concrete should slope to direct water away from the house and avoid pooling. Patios and walkways that slope toward the foundation can send water against the home during storms. Planning drainage carefully protects both the concrete and the structure.

Mortar joints deteriorate over time, becoming cracked, crumbly or recessed. Repointing removes deteriorated mortar to a consistent depth and replaces it with fresh mortar, restoring the joint's strength and weather resistance. The new mortar should be compatible with the existing masonry, and matching colour and joint profile helps the repair blend in.

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.

Concrete work is affected by weather, particularly extreme heat and monsoon rain. Pours are typically scheduled early in the day during summer, and heavy rain soon after placement can damage the surface. Flexible scheduling helps ensure the best possible result.

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.

Masonry fireplaces and chimneys can develop cracked mortar, damaged crowns and deteriorated flues. Since these components affect fire safety, they should be inspected regularly and repaired by professionals. Restoring chimney crowns and mortar joints keeps water out and protects the structure.

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.

A concrete driveway must withstand vehicle loads, heat and occasional heavy rain. Proper subgrade preparation, adequate thickness, reinforcement, control joints and drainage away from the house all contribute to a driveway that lasts for decades.

Slab thickness depends on its use. Walkways and patios carry relatively light loads, while driveways and RV pads must support vehicles and require thicker concrete and appropriate reinforcement. Using the correct thickness prevents premature cracking and failure.

Applying a sealer helps protect concrete from stains, moisture and wear, and can enhance decorative finishes. Sealers need periodic reapplication, especially on surfaces exposed to intense sun and traffic. Choosing a sealer appropriate for the finish and exposure helps maintain the concrete's appearance.

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.

Five patterns dominate. Mortar deterioration along south and west elevations from UV and thermal cycling. Step cracking through brick courses from foundation settlement on expansive soils. Brick spalling from moisture entering cracked joints. Efflorescence from sulfate-rich groundwater wicking through CMU site walls. And on 1920s–1960s downtown Phoenix and Mesa brick, hard Portland-cement patches done in the 80s–90s now causing the softer original brick to spall around the patches. Each pattern needs a different repair — we don't apply a universal fix.

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.

Cracks in block walls take different forms. Step cracks that follow the mortar joints diagonally often indicate settlement, while vertical cracks may result from shrinkage or movement. Horizontal cracks can suggest lateral pressure. The width, pattern and whether a crack is growing all help determine the cause and the appropriate repair, which may range from repointing to partial rebuilding.
