Automotive Lift Anchoring Floor Repair
Two post automotive hoists and lifts are generally bolted to the floor using compression anchors. When the lift needs to be replaced, the new anchors can not interfere with the old anchor points. If the old anchor points are too close to the new anchor points, the concrete needs to be replaced before the new lift can be installed. This can close a service bay for a month or more.
With Roadware 10 Minute Concrete Mender, we can remove the old compression anchors, repair the concrete and install new compression anchors without having to replace the concrete.
After removing the old lift, the compression anchors need to be removed. If the original anchor hole was drilled full depth, they can be driven down beneath the floor with a hammer and a punch. If the anchor are not full depth, a core drill is used to remove the anchor.
After drilling, the holes are cleaned and reamed with a reaming bit to roughen up the sidewalls. A shop-vacuum is used to remove all dust and debris. The concrete is than cleaned with alcohol or a similar evaporating cleaner. The holes have to be clean and completely dry before proceeding.
Use duct tape to mask off the holes to be filled with Roadware 10 Minute Concrete Mender™
Gather the materials needed to repair the holes. Roadware 10 Minute Concrete Mender is designed to repair cracks, spalls and holes in concrete. Not just simply fill them. The Microdoweling™ penetration of Concrete Mender into the concrete is a structural repair and can bring the concrete back to original design parameters.
Items needed:
- 80020 Two-gallon kit of Roadware 10 Minute Concrete Mender.
- 4030 grit or similar dry manufactured sand or quartz. Enough to fill the holes.
- Mixing and measuring pails. One quart paint mixing pails work well.
- Gloves, safety glasses and PPG as needed.
We made a short video to demonstrate the basic technique of filling a core drilled hole in concrete. Concrete Mender doubles in volume when adding sand. All we need to do is fill the hole halfway with Concrete Mender and then add sand to bring it up to the top. Note: In the field it may be impractical to get the bottom of the hole completely dry or clean especially if the hole is full depth into the base material. Simply repair the bottom 1/4 of the hole with Concrete Mender and sand first and allow it to cure before repairing the rest of the hole up to the top.
Measure out equal parts of Side A and Side B Concrete Mender and combine them into your mixing bucket. Mix with a stick by hand for about 15 seconds.
Pour equal parts A and b into a mixing container and mix for about 15 seconds with a mixing stick.
Fill the holes half-way with mixed Roadware 10 Minute Concrete Mender.
Add sand into the hole bringing the Concrete Mender level up to the surface. Make sure all the sand is completely saturated.
Level the surface with a trowel or stick and allow to cure for about 10 minutes at 70 degrees F (21C).
Remove the tape after the Concrete Mender cures and turns grey in about 10-15 minutes.
A finishing rubbing brick is used to quickly bring the repairs flush with the floor.
Holes to anchor the new lift are marked and drilled into the concrete. Time to test the repairs and make sure the repairs will hold the anchors for the new lift.
New compression anchors are installed and torqued to the specified level.
For the repair to be successful, the compression anchor must hold 3000 lbs or 1360 kg for 12 hours without cracking or splitting of the surrounding concrete.
Several anchor were tested. All passed and the lift was installed the next day and placed into service. Roadware 10 Minute Concrete Mender™ is designed to bring most concrete slabs back to original design strength. Repairing anchor holes prior to new automotive lift installation with Roadware 10 Minute Concrete Mender is now the specified choice for two of the largest auto service companies in the United States.

Swimming Pool Repair with Concrete Mender
What do you do when your pool has cracks and spalls and it has to be open is three days? Back in 2001, the City of South Saint Paul, Minnesota had a problem with their new splash pool. Just before opening the pool for its second season, cracks and spalls were discovered in the concrete pool bottom and along corner where the floor meets the wall. The damaged was probably caused by the first Minnesota winter for this neighborhood splash pool facility. The repairs needed to be done fast. The pool was scheduled to be open in just three days. Any delay would be a disappointment for local families and political problem for the City who spent a lot of money to build this water recreation facility.
The call went out to see if anyone could come up with a solution. Roadware Incorporated, also located in the City of South Saint Paul, received a call from the Parks and Recreation Maintenance Department to see if we had any ideas. It turns out, Roadware 10 Minute Concrete Mender™ is a great product for repairing concrete pools. The cross-linked polyurethanes in Concrete Mender and very resistant to water, chlorine and other pool chemicals.
Roadware personnel were at the pool within a few hours and repairs were made using a mixture of Roadware 10 Minute Concrete Mender and manufactured sand.
Roadware 10 Minute Concrete Mender is flooded into the spalled ares and seeded with manufactured sand.
The Concrete Mender and sand bland can be troweled in place and will cure in about 10 minutes.
Vertical surfaces can be repaired by mixing Concrete Mender with fine manufactured sand and troweled in place.
Repairs can be painted using standard methods in 10 minutes after application at 70 degrees F (23C).
All the repairs took just a few hours to complete and the pool was ready for a fresh coat of paint in minutes. The pool was painted and filled with water the next day. The Concrete Mender repairs have largely been forgotten, but continue to perform to this day.

Floor repair stands up to forklift damage.
The Microdoweling™ action of Roadware 10 Minute Concrete Mender™ can structurally, “glue” concrete back together. Pictured here is a concrete break-out caused by a forklift hitting an anchored steel bollard.
Concrete Mender™ was used to re-attach the broken concrete piece and repair the crack.
After about 10 minutes, the repair was buffed smooth and open for traffic.
About a week later, the bollard was again hit with a forklift and at the same angle. The repaired concrete held in place. The concrete broke on the other side of the bollard this time. Concrete Mender can’t stop forklifts from hitting bollards. It can help minimize the damage and make lasting repairs.
UPDATED: Less INvasive Concrete Repair | Reducing Silica Dust
UPDATED FOR 2020 – Less Invasive Concrete Repair
Reducing worker exposure to silica dust is an OSHA and job site priority.
“Workers may be exposed to dangerous levels of silica dust when cutting, drilling, grinding, or otherwise disturbing materials that contain silica. These materials and tasks are common on construction jobs. Breathing that dust can lead to serious, often fatal illnesses.” The Center for Construction Research and Training. Click here to learn how to work safely with silica.
With Roadware 10 Minute Concrete Mender™, you can make excellent crack and spall repairs with much less cutting and grinding. Standard preparation for most concrete repair products calls for invasive actions from square cutting and removal to deep cutting, grinding and sandblasting. Aggressive preparation is necessary for standard repair material like epoxy and polyureas. They are too thick to penetrate and bond to compromised concrete surfaces. Roadware 10 Minute Concrete Mender™ has an extremely low viscosity of less than 8cps when applied with a surface tension one third of water. Concrete Mender™ can penetrate and bond concrete surfaces where other materials will fail.
Many concrete crack repairs can be made with Concrete Mender™ with just a light scoring with variable speed diamond grinder. This reduces dust production by nearly 70% over conventional methods.
In some situations, cracks can be repaired directly with only a shop vacuum used to remove dirt and dust. Roadware’s needle tip application mixers are great for getting Concrete Mender™ into small cracks in fissures.
Roadware Easy Injection can make low dust repairs 24 inches deep or more without cutting, ports, or pumps.
Amazon Warehouse: Full depth crack repair without sawing.
Full depth crack repair in warehouse floors usually involves cutting open the cracks with dry diamond saws. This is a slow process and creates a lot of hazardous silica dust that needs to be mitigated. Repair contractors at an Amazon Warehouse project are using an innovative way to repair cracks in the floor without the traditional cut and fill methods.
A wire wheel can be used for preparing cracks and spalls. We recommend using a variable speed grinder with a twisted wire wheel. This generates less dust than diamond blades and still does a good job preparing the crack for a Concrete Mender repair.
After the crack or spall is repaired, grinding and buffing to make the repair flush can be made using wet methods in just 10 minutes after application when using Concrete Mender™. Other low dust methods include razor scrapping and dustless grinding equipment.
Whenever cutting or grinding concrete, have a plan to keep harmful dust away from workers and bystanders. Using Roadware 10 Minute Concrete Mender™ with these minimal invasive techniques can help keep dust exposure to a minimum.
Warehouse Floor Repairs in the Dominican Republic.
Franklin Gutierrez in the Dominican Republic is using Roadware 10 Minute Concrete Mender™ to repair multiple spalls in a warehouse floor that were causing damaged forklifts and damaged backs.
“We did 87 repairs for this client, it is a tin can production plant, they work 24/7 so there was no time to close areas for repairs , also lots of equipment very sensible to dust in the air. The major problem was that those small holes were damaging the wheels of the forklifts, damaging the back of the operators and creating possible dangerous situations for the forklift operators, because they manage very heavy loads and even a small hole could make it unstable.
We did all in two days and the client is very very happy, the problems were solved and there was no interruption for them.
This is a big plant that produces for the local market and export, its called Troquedom.”
Loose materials are removed from the spall.
Bulk Roadware 10 Minute Concrete Mender™ mixed with sand is troweled into the spall. See instructions here.
