Sunken Driveway Fixed in a Day, Pandemic Pricing

April 15, 2020 By Phil Herbst 4 Comments

It’s common for driveways to sink where they meet garage floors. Improper backfill during construction and erosion from downspout discharge are common causes. Metro Concrete Raising Inc. offers two solutions for sunken driveways.

Installation of new concrete is one option for both asphalt or concrete driveways. If your driveway is asphalt, like the one in the video, we will remove several feet, restore the base and pour a concrete apron. If needed we also can replace deteriorated concrete foundation blocks. Homeowners can drive over a new concrete apron after two weeks, but they should not park on the apron for at least three weeks to allow the concrete time to strengthen or cure.

If your driveway is concrete and in good condition Metro Concrete Raising can lift the sunken section by injecting a limestone slurry under the concrete. This is called slabjacking or mudjacking. Homeowners can drive over raised concrete immediately Contact Metro Concrete Raising for a free, no obligation estimate today.

Downside of sunken driveways

Sunken driveways, or any concrete, can be a liability. Tripping hazards and uneven surfaces for biking and skateboarding are the most common concerns. Improperly slopped driveways can channel rainwater and snowmelt into your home’s foundation and drain tile. It also can compromise the garage floor, creating channels for critters like mice and snakes that could access your home.

“Although our name emphasizes concrete raising, we provide complete concrete services,” said Metro Concrete Raising’s Phil Herbst. “This includes replacing poured concrete and block and installing new concrete and block.”

“Pandemic or not, homes need maintenance and repair. This is a good time to complete your concrete projects. We are doing our part to make it even more affordable,” Herbst said.

First Aid for Seasonal Pavement Disorder (SPD)

February 25, 2020 By Phil Herbst Leave a Comment

While Minnesota winter is the natural enemy of your home or business’s concrete, don’t wait to administer first aid for Seasonal Pavement Disorder (SPD). Act now to prevent serious conditions that could endanger your safety, comfort, investment and to reduce liability.

Reduce Salt Intake

Minnesota road crews and homeowners use a lot of ice melt each winter to prevent vehicle accident and falls. Unfortunately, salt is harmful to paving, plants and pets. If a couple of days of warm weather are forecast, sweep or blow melt chemicals from your garage floor, walks and driveway. Then rinse the surfaces with a hose to flush the corrosive residue. 

Salt is hard on vegetation, so avoid getting it on turf or planting beds. If possible, also rinse off the underside of your vehicle or get the underbody spray at the carwash to prevent more salt from dripping onto your concrete after it is clean. Be sure to allow the surfaces time to dry before freezing temperatures return. And disconnect the hose from the freezeproof sillcock so the faucet drains and does not freeze.

This late winter maintenance will prevent or at least reduce concrete pitting and extend the life of your concrete.

Minimize frost heave

Freeze-thaw cycles are as Minnesotan as hotdish.  Like all liquids, water contracts when cooled. However, unlike other liquids, it actually expands more than 10 percent when it freezes.  When the moisture is trapped under concrete, it can heave the surface. It can cause water to pool or drain where it doesn’t belong, such as along the joint between the garage floor and the driveway, between the stoop and the entry walk, or along the foundation.  The best case is that it merely causes your sump pump to work overtime. However, frost heave also can lead to wet basements, deterred footings, cracked foundations and tripping hazards. What’s more, the hidden erosion can create a pathway for rodents or snakes to get into your home.

diverted downspout

Plan a diversion

Until warm weather returns and soils dry out, you can’t do much to remedy a heaved walk or driveway. However, you might be able to address the cause. Check the downspouts from your gutters, if they exit near the top of the driveway or walk divert them away from the house. 

If you can’t install a downspout extension to direct the runoff away from paving it is better to have the water drain over the hard surface than alongside it, where it can cause erosion and introduce even more moisture under the concrete or asphalt. Just be prepared to apply sand if the melt water freezes.

Emergency joint care

 If you have an open joint in paving that is 3/4th inch or less clean the edges and press closed cell foam backer rod into the crack to keep water out.  If the void is deep, fill it with sand before installing the backer rod. Then, in spring, press the foam down to create a half-inch deep depression and seal the top with self-leveling polyurethane caulking applied with a caulking gun. You also could mark trip hazards from heaved pavement now to warn visitors until you call Metro Concrete Raising to fix the problem.

Schedule your spring checkup now

Metro Concrete Raising cannot begin to do slab jacking or concrete replacement to correct heaved, tipped or sunken concrete until the ground is frost free, usually at the beginning of April.  Customers whose projects could not be completed before winter will be scheduled first. If you are not already on our list, Contact Metro Concrete now to get your own concrete inspected and fixed in the early season.  The best way to get on Metro Concrete Raising’s schedule is to complete the Contact Form on the Metro Concrete Raising website. We may still be out plowing snow rather than at our desks in March. That’s Minnesota!

Maintenance Musts for Concrete Paving

September 7, 2016 By Phil Herbst Leave a Comment

p_100414555-270x300Pured concrete paving gets dirty like any outdoor surface. It also may experience stains from oil and mold and deteriorate with prolonged exposure to salt and water. Periodic cleaning will remove contaminants and restore your concrete’s appearance. And resealing every few years will help it maintain its good looks longer, make it easier to clean next time and prevent deterioration from ice-melt salt and moisture. The right surrounding landscaping can help too.

Landscaping problems damage concrete 

When concrete paving is lower than the surrounding landscaping, dirt and debris wash onto the surface and settle there. To keep concrete paving clean, it should be slightly higher than the ground around it and sloped for positive drainage away from your home. Turf and mulch groundcover will prevent muddy splashing from bare earth.

Concrete Cleaning extends life

You don’t need fancy equipment to clean concrete. A leaf blower, stiff push broom, soapy water, a garden hose and some elbow grease should do the trick. Pressure washing will save time and effort, but be careful not to damage the surface. Use a 25-30 degree tip held at a 45 degree angle about 6 in. from the surface so you don’t inject too much water into slab or wear away the surface.

To avoid dirty streaks, start at the lowest area and work your way toward the uppermost edge. Then rinse the entire area in the opposite direction.

For oil and rust stains, choose a chemical stain remover designed for the purpose. This includes alkaline, acidic or enzyme products. Follow label instructions carefully to avoid safety hazards. Be patient and resist the temptation to blast away with the pressure washer or be prepared to accept the damage it inflicts on the surface.

Concrete Sealing
Today’s concrete sealers may be solvent-based or waterborne. Some penetrate while others just provide a thin surface coating. They also may be specifically formulated to block the damaging effects of ice-melt salt. Applied properly, any sealer is better than no sealer and most can be applied with a simple low-pressure garden sprayer or a paint roller mounted to a long extension pole.

Choosing the best sealer depends, in part, on the characteristics of the surface. For instance, wet-look coatings enhance the color and texture of decorative concrete such as exposure aggregate stamped concrete. Whereas deep penetrating solvent based sealers offer superior salt protection without altering the appearance. It’s important for any concrete sealer to be able to breathe to allow moisture to escape. However, cure and seal products applied soon after new concrete is finished are designed to slow evaporation during the curing process. This increases the strength of the concrete.

Professional-grade sealers last longer and perform better than the consumer-grade products typically available at home centers and hardware stores. However, they may be more difficult to apply.

The Metro Way

At Metro Concrete Raising, we seal the new concrete we install and use only the highest quality professional products. We also are available to do periodic pressure-washing and resealing of any concrete we work on. Call today to schedule routine maintenance so your concrete looks its best and lasts.
