Concrete Raising

A quick­er, eas­i­er and more cost-effec­tive choice than replac­ing your concrete.

When we are called to assist a home own­er with a free esti­mate on whether they should lev­el and repair their con­crete, or replace it, they are often hap­pi­ly sur­prised they can have per­fect­ly aligned con­crete again, in a mat­ter of min­utes, sav­ing them time and money.

That’s because when com­pared to con­crete replace­ment, the process of rais­ing con­crete with polyurethane foam is inex­pen­sive (com­pared to the alter­na­tives), and is expo­nen­tial­ly faster than replac­ing the con­crete. Con­crete raised, lev­eled and repaired using polyurethane foam is often ready to sus­tain nor­mal use with­in min­utes of being lev­eled.

What types of prob­lems can con­crete rais­ing fix?

Con­crete rais­ing is a fan­tas­tic alter­na­tive to replac­ing your con­crete, often times sav­ing you over 50% of the cost of replace­ment! Some com­mon areas we raise, lev­el and repair are patios, front porch­es, dri­ve­ways, side­walks, park­ing slabs, steps, and pool decks.

Pop­u­lar Questions

• What makes polyurethane injec­tion (poly­jack­ing) bet­ter than mudjacking?

  The use of polyurethane to raise con­crete and sta­bi­lize soil has many advan­tages com­pared to tra­di­tion­al mud­jack­ing which uses cement and sand. Below are just a few benefits:
  

  Longevi­ty – Polyurethane will not shrink or break down over time

  Looks – Small­er and less injec­tions holes are needed

  Per­for­mance – Extreme­ly light com­pared to sand/​cement and very effec­tive at fill­ing open voids
  

• What caus­es con­crete to sink?

  Here are some of the most com­mon rea­sons con­crete slabs sink:

  Grav­el base was nev­er com­pact­ed prop­er­ly dur­ing construction

  Con­crete was built over soil that was once back-filled (such as around a foun­da­tion or pipe trench) and soil has now settled

  Water is drain­ing or pool­ing around the edge of the slab which can cause the base to wash away over time

  Cracks and gaps in the con­crete allow water to seep below the slab and cause sea­son­al frost heav­ing which can cre­ate voids

• How can I pre­vent my con­crete from sink­ing again after it has been raised?

  The most impor­tant thing you can do is to fill all the cracks and gaps in your con­crete where the set­tling occurred. A polyurethane crack seal­er sold in caulk tubes is the best way to do this. Make sure down­spouts are direct­ing water away from your con­crete. Also equal­ly impor­tant is to fill the area along the edges of your con­crete with soil in order to pre­vent water from wash­ing away the base.
