Help! My Seawall is failing!

SlabJack Geotechnical repairs problem seawalls and bulkheads.

Seawalls and Bulkheads are designed to prevent damage to what is behind them and do take some occasional maintenance.

Typically routine inspection would involve looking for cracks, wall movement, erosion and deterioration. If any of these problems are found a plan for repair would be formulated and the cost estimated.

Seawall repair ranges from $2500 to hundreds of thousands of dollars. Sealing a few cracks with a single component polyurethane injected in the ground along the crack would be on the low end. Using tieback anchors to pull the wall back into alignment may be in the ten(s) thousand dollar range. Significant damage, movement, void space, large walls or if buildings are involved needing an engineer, costs can go up quickly.

In the photo above we sealed 30′ feet of cold joint (you can see the material sealing the joint) above the waterline. We sealed the footer which was completely undermined in one section and curtain grouted an additional 40′ where the soil was subsiding behind the wall. Total cost was just under $15,000

While not inexpensive, it is much, much less costly than replacement which is getting more difficult due to the challenges of permitting.

If you are concerned about your Seawall or Bulkhead call today for a free inspection and if needed an estimate for repairs.

Last year we added a full time rig in the Spokane/Coeur d’alene market and for 2018 we are announcing that Puget Sound will now have a full time rig too.

In addition to the additional rig we have added additional support personnel. One of the biggest complaints most people have with contractors is you can never get ahold of them, it drives me nuts! it’s as if they are afraid of success.

Slabjack Geotechnical is a different kind of company. We are redefining what hiring a contractor should feel like.

From the initial contact, to the estimate to the completion of the job and warranty follow up a year later. Our aim is to impress upon you the customer your pre-eminent position in our company. Our goal is total customer satisfaction.

So what is different about dealing with Slabjack Geotechnical?

-When you call you will speak to a real person, not an answering service or a machine, we staff our appointment center Monday through Friday 8:00 to 5:00. In that rare instance we miss you we do call back.

-We schedule in person proposals, not “estimates” (in most causes) so you don’t have to worry about overage charges or “what if’s” Other companies make you pay for their mis-calculations, not us.

-Our production leaders have literally raised thousands of concrete slabs from settled driveways, to sunken patios, porches and pool decks to sidewalks, shops and stoops. Nobody comes close to our experience when it comes to Geo-polymer Slabjacking, nobody!

-Our estimators are also experienced at raising slabs so they know what can be done, how it should be done and what to be concerned about. This additional experience is invaluable for accurately estimating your job and why in the vast majority of cases we present proposals not estimates so you know exactly what’s going on with your slab, exactly how we are going to fix it, and exactly how much it’s going to cost.

-Our company proactively reaches out to insure our clients are satisfied a full year after doing their job via-Email and if any settling has taken place an appointment is set to correct the issue. When was the last time a contractor did that for you?

Failing Seawall or Bulkhead? SlabJack Geotechnical can help!

We just recently completed a residential Seawall stabilization project in Bellingham using a single component polyurethane to permeate the soil behind the wall and to seal cold joints.

Using a single component polyurethane mixed with a catalyst that reacts with water, Slabjack Geotechnical is able to inject material deep behind the wall which permeates the soil to return stability to the Seawall or Bulkhead.

This method is by far the safest way to stabilize Seawalls and bulkheads. Plural component polyurethane can place enormous lateral stress against the wall and cause damage such as bowing, in the case of walls, or in the case of bulkheads, moving rocks out of position or worse.

There are applications where plural component polymers make sense but they are not as thorough at sealing cold joints, filling underneath footers and creating a watertight barrier behind the wall.

If you are dealing with soggy soil behind a Seawall or worse, give us a call today,
