It’s unsightly, it’s dangerous, it’s a potential liability but it’s easy to fix.

Concrete settlement is a very common problem affecting not only residential neighborhoods but municipalities commercial enterprises and industrial facilities. What causes concrete to settle?

Failure to prepare the site. If soil was disturbed during construction was it re-compacted? Was there a 4-6″ layer of compacted gravel placed under the slab? These two primary issues are the cause of much of the settling commonly found in new construction.

The next most common cause of concrete settlement is excess water. Dealing with water runoff is generally not on a builders mind at the start of construction, it should be. Trying to figure out where you were going to put downspouts, sprinklers and  water features after sidewalks porches and driveways have been poured is poor planning and asking for concrete settlement. Having a place for your run off to drain such as french drains well away from structures or into municipal water supplies if allowed in your jurisdiction will help your concrete remain stable.

In addition to the above, the type of soil that is predominate in your area plays a role in its ability to support structures. Whether it be sand, clay or silt each has advantages and disadvantages depending on its use. Some soils don’t drain well others are prone to wash out, still others will actually expand as much as 10% with water!

If someone failed in the planning phase and you are dealing with concrete settlement give the concrete raising of leveling professionals a call today.

Can water be a cause to my settling issues?- Slabjack Geotechnical

1-855-752-2522

www.SlabjackGeotechnical.com

Poor compaction coupled with excess water causes virtually all the settled concrete we see.

We got a call from a homeowner that their fifty year old home was experiencing some settling on a porch and some attached brickwork. I asked, “the house is fifty years old and the settling just happened?” She replied yes but they had recently installed gutters and downspouts and she suspected that might be the cause.

A site visit showed that she was correct, the downspouts was dumping runoff right at the point of settling. An estimate was provided and the work was completed using Geo-polymer Slabjacking as well as sub grade concrete and steel bracing for the decorative brickwork.

This is so common.  Here’s how to prevent the problem;

New construction – install gutters and downspouts before concrete is poured, insuring water is directed well away from porches, walks, driveways and foundations. Where municipal codes allow, tie into storm drains, if not, dig French drains or use other methods to avoid saturating soils near concrete slabs.  Other concerns are landscape plantings too near foundations and slabs, tree roots, ponds and sprinkler systems.

Existing homes – design the gutter system with the intent to have water going somewhere other than near concrete slabs and structures. This may necessitate tunneling under walks with a drain pipe directing water well away from the home. If this is impossible a French drain can be dug, rain barrels used  or use the retracting downspout extensions that unroll to direct water away from structures when there is run off.

Take the time before settling occurs to correct deficiencies and you will avoid the problems associated with sinking concrete.

Slabjack warranties generally require the correction of the problem that created the original settling. In the vast majority of cases it means making corrections to your drainage system, eliminating plantings that require substantial water, reducing sprinklers or using drip lines instead.

Slabjack Geotechnical is a great resource when it comes to diagnosing the cause of settling and recommending corrective measures to prevent further settling. Call today,

Culvert Repair and Leak Sealing- Slabjack Geotechnical

www.SlabjackGeotechnical.com

One of the things we do to save water districts and irrigation districts as well as municipalities a ton of money and down time is leak sealing. It is a fast and lasting solution to the problem of cracked and leaking culverts, canals and pipe.

The solution is our expanding hydrophobic polymer. It pushes out water and seals cracks, joints and holes up to several inches in diameter. In many cases we can even work with water in the culvert or canal.

Culverts are prone to undermining especially during high water flows such as winter runoff. In addition, joints can and do fail and cracks can develop. These problems, if not sealed result in loss of water, washouts, settling bridge approaches and worse.

Using our patented hydrophobic polyurethane grout Slabjack Geotechnical seals leaks into and out of pools, culverts, canals, pipes, manholes and just about anything else you can Imagine. Call today.

www.SlabjackGeotechnical.com

According to the National Floor Safety Institute the average medical cost from a slip/trip fall is $22,800! The potential legal costs and jury awards are several times that amount. Rather than ignore the “little trip” have it fixed by Slabjack Geotechnical.

Whether it be a walk from your driveway, a trip on your driveway or a sidewalk by the street, you, the homeowner, not the city, are responsible for maintaining the walk and keeping it free from snow, debris and known hazards such as trips due to settled concrete.

A quick and unobtrusive process, Slabjacking raises settled concrete through the use of an expanding polymer grout. Most jobs are done in a couple of hours and the walk is available for immediate use. No waiting for forms, concrete and curing. No destruction of lawns or plant, just a quick drill, inject and patch.

Concrete Voids- Slabjack Geotechnical

www.SlabjackGeotechnical.com

Voids under concrete eventually lead to cracking and/or settling concrete. Voids are created when concrete is partially supported by base soils or through the use of anchors or rebar to foundation walls or through the use of Sonotubes. As the soil settles or is carried away by other means a gap opens up between the soil and the bottom of the concrete slab resulting in a loss of support.

Un-compacted fill dirt, erosion, burrowing rodents, decaying organic material even a loss of moisture in the soil can create voids. Once there, voids are difficult to fill. Smaller slabs such as walks can be packed with gravel or sand to fill voids but this is not practical for larger slabs such as driveways or patios. These need a method that supports but doesn’t lift the slab. Using an expansive polymer is the ideal material for void filling for several reasons such as;

Polyurethane can travel several feet in every direction to fill voids, fissures and holes. It has the ability to consolidate organic material, sand and loose rock. If properly monitored Polymer injection can provide support without excessively lifting or stressing the slab which causes fractures.

The question with new construction is what should I do? Settling of soil in new construction can go on as long as 10 years so the question becomes do you live with it and replace your broken up concrete at some later time or do you try and preserve it knowing that you may have someone out 2, 3 or 4 times in the next decade to shore up what should’ve been taken care of during initial construction. Immediate replacement of settled concrete or concrete with voids is not a good choice as settling is not yet complete.

If you see a void opening up under your concrete slabs give the concrete raising and leveling professionals a call we will get you taken care of.

Having Drainage Issues?-Slabjack Geotechnical

A big part of eliminating settled concrete is to plan your drainage system. Addressing runoff will pay dividends for years to come not only in reduced settling but in keeping your basement dry and foundation stable.

Some communities do not allow gutters to be directed into storm drains or into the municipal sewer system and therefore must be handled by French drains and simple sloping of top soils to direct runoff well away from structures.

Time spent planning where water will go and the amount anticipated is something your builder should do, if not have a conversation about getting water well away from any concrete walks, drives, porches, etc.

Time and planning spent here can save a significant amount of money and headache down the road.

If that didn’t happen and you are dealing with settled concrete give us a call, we can help.
