Each septic system is like a new puzzle with some familiar pieces!

We had extra help show up to keep progress moving along on this install!

Part II of the foundation!

Forming the walls took us a little bit, these were 12’ foot walls at 12” thick with a 6” thick ledge on the bearing sides to accept the pre-cast hollow core slabs.

On pour day, the first pump truck that showed up got set up and just before pouring concrete in the hopper, his pump went down! Thankfully JDE Concrete Pumping was able to pull another pump from Lansing for us and HSV Redi-Mix took care of keeping the concrete ready to go!

Personally, it was a great feeling to see the forms filled and standing strong at the end of the day!

We came back and stripped the forms and got our waterproofing on, and stone and tile placed!

Sewer Replacement!

We had to remove the existing forced main sewer that was servicing this home, and connect it to the new gravity sewer main that had come through.

We had pretty tight tolerances for making the gravity sewer work without having to get into the road and lower the rise of the lateral off of the sewer main.

For many the replacement of a sewer line (or septic system) is a very unexpected expense and can also be damaging to the existing yard, landscaping, driveway, sidewalks, etc. so whenever we do projects like this, we pride ourselves on restoring your property so that your not left with more work to be done after we leave!

Also, thankful for the relationships we have been able to make with other local contractors who always provide top notch service when we call!

The infrastructure below ground is something we all depend on a daily basis, and it takes a team to keep it operating the way it should!

Give us a call if you have a sewer related project coming up, we’d love to provide an estimate to you and earn your business! 616-824-3984

Sewer Replacements are large part of what we do at Coats Grove Excavation!

We have the equipment to do Trenchless replacements; however, sometimes it does make more sense to excavate a new line.

The existing sewer line was approximately 150’ in length and ran across the yard to another intersection, with the sewer main in the center of the road. Working in the center of the road adds another layer of expense to the job as well as the need for traffic control…

We presented the customer with the option to tie into the main in front of their house which was scheduled to be totally redone in the coming year or so…it also would cut about 90’ of length off of their sewer line. They saw the value to a shorter sewer line that would also be connected to a new sanitary main eventually.
The city came out to do a new stub out on the sanitary main for us to connect to and we trenched from the home to the lateral stub and installed a new 4” Sch. 40 PVC sewer.
Upon inspection, we were able to start cleaning up the yard and prep the sidewalk for concrete to be replaced.
Our customer had us replace a few other sections of sidewalk that were sinking and cracked/broken.

If you’ve been dealing with sewer issues and are interested in getting a Free Estimate for repair or replacement of your sewer…give us a call at 616-824-3984! We’d love to have a chance to earn your business!

Are you ready to fix the potholes for more than a few weeks or months this time?

Is water washing out all your new gravel or asphalt millings?

If you need more time to answer those questions, Go ahead and take a look at how we helped one of our customers correct those same issues!

Maybe you were told you just needed to add gravel or millings to the top of the driveway, but the potholes returned within a few months of driving, or the first heavy rainfall washed out the gravel.

Did your contractor consider how surface water interacts with your driveway and how it affects the longevity of your driveway?

If you need help solving the issues with your driveway, give us a call at (616) 824-3984 or message us on Instagram/Facebook. You can also visit our website at www.coatsgroveexcavation.com

Advanced Treatment Septic System-

This is another option for advanced treatment made by Infiltrator called AES. This system utilize another proprietary piping product that allows the system to be installed within 12” of the water table! *A standard drain-field requires 3’-4’ of isolation or a mound system is the standard alternative, which takes up a large area, adds an extensive amount of labor/aggregate/trucking & overall cost to the install*

The AES product also does not require the use of 6A stone to treat the effluent, it utilizes a pressurized PVC piping inside of the AES to force even distribution of the effluent and treatment occurs within the AES piping. We also install Cleanout access on every lateral for future inspection/maintenance of the system!

Another great option for treating effluent if you have a less than ideal site conditions.

Note: these systems can be installed in ideal site conditions as well you just have to fill out the correct permit!

If you are having problems with your current septic system or are in need of a new/replacement system, please give us a call at 616-824-3984! We’d love to chat with you about your project!

Upgrading to an advanced septic system with Infiltrator AES. This system utilizes 12” piping with geo textile fabric to promote bacteria growth, crucial for efficient wastewater treatment.
