Additionally, the engineer will be the professional that will not only quantify the amount of cracking but will also provide you with the best method of repair. Your structural engineer will be the person who determines which cracks are serious and which are not.

In any event, any type of crack should be filled at a minimum. Small cracks typically do not constitute a serious structural problem although a review by a structural engineer is always recommended. It is normal for a concrete parking structure to contain cracks. All these items come together to cause fissures in the concrete on a long-term basis. Of course, this is normal and you shouldn’t be alarmed. The heat and cold cycles of day and night cause the structure to expand and contract. If you are in a parking garage and you stand still while cars are passing by, you will likely feel yourself vibrating. In other words, it’s those cracks that are caused by the constant movement, expansion, and contraction of the structure and the vehicle traffic. These reasons range from pouring a bad batch of concrete, to improper curing during the construction process.

At Bay Area Underpinning we’ve been repairing and replacing foundations in Northern California since 2005, and to date have completed over 2700 repairs.Cracks on concrete appear due to many different reasons.

If you have a sinking garage slab you’re worried about, and you live in an area we service, contact us today for a free inspection. In this case, we would just remove the damaged concrete slab, compact the base rock, and repour a new reinforced concrete slab. Sometimes, a sinking garage slab may need to be totally replaced because it’s in very bad condition.

Polyurethane foam is used to fill the void under the garage slab and provide additional support.

The steel push piers and hydraulic jacks can now lift and relevel the sinking garage slab and the foundation.Steel piers are driven through the brackets until they reach load-bearing material.

The push pier brackets are attached to the footing of the foundation in the affected area.

If the sinking garage slab is connected to the perimeter foundation, it can be releveled using steel push piers. However, cement slurry weighs a lot more than polyurethane foam and mudjacking usually requires drilling larger, 2 inch holes in the slab. Polyurethane foam injection is a good alternative to a procedure known as ‘’mudjacking’’, which uses a cement slurry instead of a lightweight polyurethane to lift the slab.

As the polyurethane foam spreads out underneath the slab and expands, it fills any voids and lifts the slab back to its original position.

Small, 5/8 inch holes are drilled into the slab and polyurethane foam is injected into them.

In most cases, if the sinking garage slab is not connected to the perimeter foundation, it can be re-leveled using polyurethane foam injection (also known as ‘’slabjacking’’). Of course, if a settling garage is also attached to a house, it will put stress on the house and cause it to settle as well.

In this case, the sinking garage slab would be repaired using polyurethane injection, while the perimeter foundation would be repaired using push piers. Signs this might be happening include a sloped garage floor, large cracks in the garage floor, or a visibly out-of-level garage header. On the other hand, if a sinking garage slab is attached to the perimeter foundation, there’s a chance the entire garage is experiencing settlement.
