Concrete Repair

Concrete Repair in Sandy, UT

Concrete rarely fails on its own; something under it or on it changes first. On sloped lots that something is usually water: runoff from uphill, a downspout emptying at the slab edge, a sprinkler soaking the same spot every night, or soil that settles once it gets wet. So a repair starts by finding the cause and fixing it, then choosing the right remedy for the concrete. A sunken walk can often be lifted back into place. Cracks can be cleaned out and sealed. A surface flaked by salt can be resurfaced. Some panels simply need to come out.

Foundation cracks get the same approach. Some are ordinary shrinkage from when the wall cured, and crack injection seals them against water. Others mean soil is moving, and those call for more: cutting out and replacing damaged concrete, piers driven down to firm soil beneath a settling section, or stabilizing a wall that has started to bow. Waterproofing, grading and downspout extensions keep water away afterward. On steps, porches and patios that have tipped toward the house, lifting or replacing them also restores the slope that keeps water off the foundation.

How it works

Concrete Repair, step by step

  1. 1

    Find the cause

    Look at drainage, downspouts, sprinklers and the soil around the damage.

  2. 2

    Choose the fix

    Weigh lifting, sealing, resurfacing and replacement for each damaged area.

  3. 3

    Repair the concrete

    Lift, inject, resurface or replace, matching slope and drainage to what surrounds it.

  4. 4

    Keep water away

    Extend downspouts, correct grade and seal surfaces so the damage does not return.

Questions

Concrete Repair questions

Why does concrete on bench lots settle?

Usually because the ground underneath changed. Fill placed during construction keeps compacting for years, some bench soils lose volume when they get soaked, and water from roofs and sprinklers finds the weak spots. Fixing the water source comes first, or the repaired slab will drop again.

What affects the cost of a concrete repair?

The method more than anything: sealing a few cracks, lifting a sunken panel, resurfacing a flaked driveway and replacing a foundation section are very different jobs. The size of the area, access, and any drainage work needed to fix the cause add to it. Repair is often far less work than replacement when the concrete is still sound.

Do concrete repairs need permits?

Most flatwork repairs, like sealing, lifting and resurfacing, do not. Structural foundation work, such as piers or replacing part of a foundation wall, may need a building permit and an engineer's input, and city sidewalks or approaches in the right-of-way fall under the city's rules. Any digging starts with an 811 call.

Should I repair or replace my driveway?

Repair when the damage is local: one or two sunken panels, a few cracks, or a surface that flaked while the slab underneath stayed sound. Replace when cracks run everywhere, many panels have moved, or water drains toward the garage and only a regrade will fix it. Seeing the driveway in person settles the question.

Can a cracked foundation wall be fixed?

Usually, and how depends on the crack. Thin shrinkage cracks are commonly injected from the inside, while cracks that let water in may also get exterior waterproofing and better drainage. Cracks that are widening, offset or paired with a bowing wall point to soil movement and call for stabilization or piers.
