Who do you call for Concrete Repair In Richmond?

W.J. Rapp of course!

The severe cold weather in Richmond, Virginia caused major problems such as: main water lines breaking, electric outages and lack of heat. Many offices, construction projects and major infrastructure systems had damage. Richmond is not used to cold weather that lingers below 32 degrees for over a week. This extreme cold may have caused problems in aging infrastructure and may force early repairs that were not budgeted but have now been raised to a higher priority.

What causes damage to concrete in cold weather?

a. Salt and chemicals can delaminate concrete surfaces

b. Salt that is placed on concrete and remains there for long periods of time

c. Salt that is placed on concrete and washes down and collects in one location can turn concrete into sand and aggregate.

Helpful Hints:

To obtain traction on concrete use sand or kitty litter

Snow blowers can be an effective way of moving snow from pavement surfaces.

New concret that is poured during the winter should never be poured on frozen ground.

Concrete that is poured in low temperatures should be covered with blankets and remain covered until outside temperatures are above freezing and rising in consecutive days.


Here are a few examples that W. J. Rapp can help you solve as part of your team:

Cracks in Foundations & Walls

Due to this severe weather a foundation may suddenly show cracks that were not there before, because of the age and condition of the concrete. The soil expands and contracts and could produce such a result. Fortunately, W. J. Rapp has the expert team who can fix your office, manufacturing facility or other concrete wall or foundation challenges. W. J. Rapp has been repairing concrete for decades in the Richmond area. Call us we can work around your schedule as well. We know how important it is to keep your equipment and operation running.

Drainage Issues

Another issue that may become apparent because of this severe weather is ”Drainage Issues”.

The snow, then freezing, then rain is a combination that may reveal drainage problems that needto be resolved. Standing water in this weather becomes a major problem when it freezes. It may cause cracks in the concrete or simply a slippery condition that is unsafe. W. J. Rapp has experience in dealing with drainage issues. Often we have redone or built new French drains and other types of drains for customers per their engineering specifications. Give us a call we can tackle these problems together. Drainage is a big deal and we have the team to help solve those issues.

Construction Repair

W. J. Rapp has a broad range of services that can help you get through unplanned construction challenges. Pouring concrete in different types of weather is challenging and you need a concrete contractor who can advise you on the best approach and how to get the best Job for your project.

So if you have a wall, concrete drive, a pad or something that has been damaged because of severe weather, age or any other reason give us a call.

“The selection of  W. J. Rapp Co., Inc. to do the demolition and pouring of the new slab was a good choice by Richmond Primoid. “

Linda, Property Manager


Dear Kenny,
I wanted to take this time to let you know how much the church appreciates the work that was done on our extensive garage renovation. From the very beginning I had a good feeling about this job and the contractors that were awarded this project.

Bob Smith handling the drawings and your participation in all of the meetings that we had concerning this project, with all of the many different sub-contractors, were always done on time with the greatest care to make sure the church received the best job possible.

I was so happy when Richmond Primoid was awarded the bid and selected to be the main contractor because I have worked with this firm on many different occasions and knew they would take care to give the church a quality job. The selection of W. J. Rapp Co., Inc. to do the demolition and pouring of the new slab was a good choice by Richmond Primoid. The day of the slab being poured I was so amazed to see all of the chief officers of their companies there at 5:00 am to oversee this work.

Bob Smith from your company was first one on site and remained through the entire day’s activities.

Richmond Primoid selected a good project manager, Wes Coston, and he made sure to always ask what we wanted and then explained and answered my many questions about the work detail.

We could not have been happier about the way this renovation progressed. We set the goals and deadlines and they were all achieved. I have done many major projects in my 20 years at the church but found this one to be without a doubt one of our finest.

Please accept our thanks for a job well done and pass along our thanks to all of the many companies that were involved in this project. I look forward to working with your firm again and will indeed call on you when we need a consultant or a structural engineering firm.

Hope you have a good holiday season.

A local church had a parking deck that needed repairs. Richmond Primoid was brought in to make various structural repairs to parking deck. In addition, 6,000 sq.ft. of parking deck area had to be removed and replaced with new concrete. Expectations were high and several goals were set and then met.

  • Total project needed to be complete in 90 days.

Richmond Primoid and W.J. Rapp teamed up to meet this challenge.

  • Second Floor 6,000 sq. ft. area of concrete had to be removed and replaced.

This required the removal of all underside electrical and fire protection.

This also required design of steel support for the front wall of the existing building to support the wall and building before floor could be removed.

Entire underside of the second floor was scaffold.

The upper floor was cut into pieces that could be carried out to dumpster.

Headroom was only 7 feet tall which limited access.

  • Steel beams Removed and Replace

Upon removal of the floor, deteriorated encased steel beams had to be removed and installed where needed.

R.S. Harritan provided structural steel work to allow the concrete steel beams to be incorporated into a new structural slab.

  • New Concrete Slab

The slab was poured with a 5,000 psi mix that was reached in 7 days.

The concrete had a corrosive additive added.

  • Meet limited time frame and access demands

Due to the location of placing concrete…. trucks and a pump truck the pour had to take place on a Saturday morning at 5:30 a.m.

Upon completion of the pour and after the 7 days break shoring was remove.

Upon completion of the pour and after the 7 day break shoring was removed and restoration fo the electrical and fire Protection.

The photos below document the work at different stages of completion. This was a significant amount of concrete. Over 300 yards of concrete were removed and replaced to complete this important parking deck repair. If your parking lot needs concrete repair W.J. Rapp has the experience, the equipment and the knowledge to help you get your job done correctly.

We are constantly looking for ways to prevent hazardous or safety issues and continually provide safety goggles, helmets, gloves, steel toed boots, and any other personal protective equipment that may be needed.   We strive to make them aware of hazards and solutions that keep them safe.

Many of the large company’s we work for require our workers to go through training. Often this training includes safety and then a separate training that is site specific.


Examples of site-specific training may include simple requirements such as:

Vehicle speed limits, no cell phones while driving, and back-up equipment safety requirements. They may also educate and train workers on requirements like: Material Safety Data Sheet (MSDS) and other safety or reporting requirements.


Safety Training can include a wide variety of items but here are just a few.

  1. First -Aid & CPR- Many of our clients offer and require basic First-Aid and CPR training.
  1. Falls- areas that they can trip, slip, or fall down.

The job site must be neat and clean with dangerous objects and construction

debris are constantly removed from a job site for safety. Stairways should

have treads and eliminate slippery conditions.

  1. Trenches – Trench collapses are a common hazard on a job site.

Trenches have specific requirements. If they are over 4 feet deep we are often required to get specific safety equipment and have individuals we work with who provide specific recommendations to trench safety. We work closely with your team to meet your requirements.
