SURFACE PREPARATION

Indoor concrete surfaces which have been poured incorrectly or subsequently damaged-whether structurally or aesthetically-can set a project back significantly, or impede day-to-day operations. Penhall Company can remove existing surface coatings, remedy common concrete pouring problems and prepare concrete surfaces for resurfacing, or to create safer walking and driving surfaces.

SURFACE COATING REMOVAL

FLOOR SCRAPING

Remove old or worn-out floor coverings such as ceramic tile, linoleum, laminate, vinyl, carpet, glued wood, and roofing materials. Penhall Company offers a complete range of scraping services for the removal of bonded floor coverings.

FLOOR SHAVING

Shaving is great for removing anything that cannot be removed by other means. A drum with a diamond blade is placed inside the drum body and rotates at a very high speed, grinding away the surface. The dust and dirt generated by the shaver is transferred to a dust collector, making the process virtually dust-free during operation.

SURFACE PREPARATION

GRINDING

Concrete Grinding Applications range from preparation for and the removal of coatings, surface flattening, honing and polishing of concrete and natural stone surfaces. Concrete Grinding leaves a Concrete Surface Profile raning (CSP) from 1 to 3.

SHOT BLASTING

Shot blasting is used to clean and retexture concrete surfaces. Shot blasting is a process of blasting a steel abrasive material at the surface. After the media hits the surface it is recycled and dust is collected to a dedicated dust collector. This makes the process almost dust free in operation and leaves the surface at a CSP ranging from 3 to 7.

SCARIFYING

Scarifiers, also known as surface planers or milling machines, are used to cut or scar the surface of concrete with the use of tungsten carbide cutting tools that rotate around a drum. Scarifiers remove concrete quickly and aggressively, leaving a CSP ranging from 6 to 9.

CSP PROFILES

Proper surface preparation of an existing concrete floor is essential for achieving a successfully completed project. Resurfacer, self leveler, sealer, coating or stain should only be used after proper surface preparation. Preparing the existing concrete surface properly will save you time and cost. The International Concrete Repair Institute (ICRI) has defined ten classifications for proper surface preparation, each profile carries a CSP Number ranging from 1 (nearly flat) through 10 (very rough).

CSP-PROFILES3

SURFACE FINISHING

Finished concrete is a very cost effective solution and environmentally friendly solution. When a concrete floor is cast the strongest material, the stone aggregate, settles just below the surface leaving mainly cement at the upper surface. Once surface coatings are removed and the proper surface preparation is in place concrete can be finished to achieve the desired results. The final result is a highly durable, low-maintenance flooring, eco-friendly solution.

Polished-Concrete-1

Polished Concrete

Polished concrete floors are popular in industrial and commercial facilities due to their high durability, low life cycle cost, slip resistance and aesthetics.

Brushed-Hammered-Concrete-1

BUSH HAMMERED CONCRETE

Bush-hammering concrete is a process that enables you to achieve a similar effect as natural cut stone. Bush-hammered concrete is ideal for swimming pool areas, or for anti-skid surfaces in pedestrian areas.

Grooved-Concrete-1

GROOVED CONCRETE

Concrete grooving is the process of creating patterns along the surface of concrete to prevent slipping. A wide range of groove patterns can be obtained using different configurations of blades and drums.

TESTIMONIALS

Often when Thompson has used Penhall it has been in an outage situation where safety, timing, and production are paramount. Penhall has always successfully completed the work on time and within the agreed upon budget.  They have a meticulous attention for detail, a great regard for safety, and are readily available and willing to answer any questions. With their numerous years of experience, they were more than capable of thoroughly handling any problems that arose. 

 

In my opinion, Penhall would be an excellent choice to be considered as a critical team member of any industrial construction project.

I contacted [Penhall] for 2 floor scans on [a] 5th floor room. [They were] able to come and complete the work needed by [the] afternoon. We thank Penhall for always being accommodating for our project success

Layton Construction Company, LLC

The scan done of our existing slab saved both the owner and myself money and headaches. The scanned lines were undocumented power lines for future expansion. If we would have hit those lines it would have been a mess and would have not only cost our project money, but also the project in the future that is planned for those lines. Thank you for what your team did.

The work performance of Josh, Henry, and other crew members has been exceptional.   The crew arrives on time and prepared to work.  The Penhall crews have met or exceeded expectations during their time on the project.  I was fortunate enough to witness several operations, including the rebar scanning, which turned out to be a new learning experience for me.  Karina took the time to teach me how the rebar scanning device worked.  In addition, Penhall crews assisted with resolving any unknown issues that presented a challenge.  For example, Henry played an active role in resolving issue of avoiding rebar during the coring operations and minimized any potential impacts.   

 

 The communication efforts between BZJV staff and Penhall demonstrated true partnering between contractor and sub-contractor and to the success of all.  I personally enjoyed working with Penhall and look forward to continuing the working relationship in the future.
