ONE YEAR LIMITED WORKMANSHIP WARRANTY
    
At DPS, llc, all work will be completed in a substantial workmanlike manner according to standard practices.  We work very closely with our concrete producers and material suppliers to provide you with the highest quality projects.  We take great pride in our work and will do everything we can to satisfy you as a customer.  However, all of our concrete work is created by humans and even under the closest supervision possible, small imperfections can and will be expected.  Despite the skills of our workmanship, the quality of our materials and the strength and durability of concrete, our product is not without its inherent flaws. The information that follows provides some of the common issues that you can expect when working with concrete and provides suggestions on customer care and usage.  If we are presented with an issue that exceeds the regular industry standard, we may repair or replace, as determined at the sole discretion of DPS, llc.   Notice is given that all repairs are promised to return the subject to it's as built integrity - not to its as-built appearance.  No warranty is expressed/implied regarding the cosmetics of the repair.  The subject's appearance will be considered secondary to it's long term functionality and durability.
    
Concrete can be damaged by many factors beyond DPS, llc control.  Damage from wear and tear, de-icers, chemicals, equipment, vehicles and other things that are out of DPS, llc control and are not covered by this Limited Workmanship Warranty.  DPS, llc is not liable for repair conditions caused by misuse or abuse, ground settlement, winter conditions, weather, accidents, or acts of God.
 
This warranty does not apply to, and is waived by the customer as to, any construction work that has been subjected to an accident, misuse and/or abuse, nor does it apply to any construction work that has been modified, altered, defaced, and/or had repairs made/attempted by the customer or others.
  
This Limited Workmanship Warranty expires one year from the date of completion of the project.
  
Furthermore, it is the customers responsibility to caulk all expansion joints, construction joints, and cracks and maintain caulk at least annually. It is also the customers responsibility to apply a sealer that will prevent salt and other products from damaging the concrete. The caulk and sealer are recommended to be applied immediately after the concrete is 28 days old. It takes 28 days for concrete to cure to 99% of specified strength. If the caulk and sealer is applied before 28 days, the moisture content of the curing concrete is likely to cause the caulk and/or sealers to fail. All warranty by DPS, llc will be null and void if concrete is not caulked and sealed with industry acceptable (high) standard products between 28 and 60 days of placement.


WHAT TO EXPECT:
 
HOW LONG TO WAIT TO DRIVE ON CONCRETE: It is recommended to not drive vehicle on concrete until after it has been caulked and sealed after the 28 day cure period. It takes 28 days for concrete to cure to 99% of its specified strength. Placing a load on the new concrete prior to its proper cure period increases the risk of failures to the product.
  
CAULKING AND SEALING: It is the customers responsibility to ensure that concrete is caulked and sealed. DPS, llc would be happy to provide an estimate for these services at your request. Caulking and sealing should be done between 28 and 60 days after concrete placement. Applying caulk and sealer prior to 28 days after placement is not recommended because the concrete is still curing and the moisture content of the curing concrete will likely cause the caulk and/or sealer to fail. It is recommended to not drive vehicle on concrete until after it has been caulked and sealed after the 28 day cure period.
 
CRACKS:  Concrete WILL crack.  We don't like it either but it will happen so we CANNOT guarantee that concrete will not crack, even in spite of all precautions having been taken.  If a crack appears, we may be able to assist in the prevention of further cracking.  DPS, llc recommends placing rebar a minimum of 2’ on center to prevent heaving, settling, and separation when cracks occur. The industry standard for repair or replacement for cracked concrete is greater than 1/2" of an inch displacement either in height or gap.  Cracks that exceed 1/2" of an inch in height or gap may warrant repair or replacement.  If we determine that repair or replacement is required, we will replace or repair only the affected area.  Repair of concrete cracks with caulk or mortar will be considered an acceptable form of repair.  PLEASE NOTE:  Surface or hairline cracks may not be covered.  Top coats and caps over existing concrete are NOT covered. Replaced concrete will likely be a different finished color and texture than original. DPS, llc will not warranty any cracks what so ever even if greater than 1/2" separation in height or gap if rebar is not placed at least 2’ on center. If concrete was not caulked between 28 and 60 days after placement, DPS, llc will not warranty cracks
 
FLAKING, SPALLING, SCALLING, PITTING, POPPING:  While concrete is very durable, it is not always without flaws.  Harsh weather may cause the surface of your concrete to flake or pop off.  It is possible that a stone or stone(s) close to the surface will be exposed but such exposure WILL NOT compromise the integrity of the slab.  We are unable to warranty any damages caused by harsh weather as mother nature always has the upper hand on us.  The industry standard for repair or replacement for flaking or popping concrete is a minimum of 20% of the total work area being affected.  Depending on the issue, we may warranty flaking or popping concrete if 20% or more of the total work area is affected.  If repair or replacement is required, we will repair or replace only the affected area. Fertilizers including but not limited to ammonium sulfate and /or ammonium nitrate aggressively attack concrete. Be cautious when you or your lawn care provider are applying lawn care products to keep it off of the concrete. These products are certain to cause scaling, pitting, and spalling when placed on concrete surfaces. WARRANTY BY DPS, llc IS NULL AND VOID IF CONCRETE IS NOT PROPERLY CAULKED AND SEALED BETWEEN 28 AND 60 DAYS OF PLACEMENT.
  
DISCOLORATION:  It is NOT possible to match the color of your existing porch, sidewalk, driveway, etc.  Sometimes different pours on larger jobs are subject to variation in color.  Color variations are minor and may fade within time.  If you are considering replacing only a section or sections of an existing driveway, patio or sidewalk, please be aware that a color difference is very likely (newly poured section vs. older section).  It may be very noticeable and may take years to blend together.  Gray Concrete can make no warranty that our work will match your existing product.
 
Colors represented on a computer screen or a printed brochure are just a representation of results and should not be relied upon for the final color of your project.  Despite our best efforts, minor discoloration can still occur.  There are a variety of different factors (such as: variations in slump, cement type/brand, finished texture, timing of operations, the curing process, choice of release agents, surface treatments, humidity and other weather conditions, age of concrete, etc.) that can and may produce distinct variations in color appearance.  Color variation is not covered by this warranty.
 
SHIFTING and SETTLING:  It is common for any concrete flat work including but not limited to; parking lots, steps, driveways, sidewalks, porches, patios and garage floors to have some cracking or shifting over time.  This is not necessarily a sign of poor We plate tamp the surface of the subgrade immediately below the bottom surface of the concrete that we place. There is no way for us to prevent sub-grade settling, gutter downspout placement, grading direction beyond surface of concrete, underground root growth or shrinkage of the subsurface layers.  We CANNOT warranty against settling because the sub-grade level is beyond our control.
 
FROST HEAVE and CRACKING: Throughout any given winter there are many freeze-thaw cycles.  During these events your concrete is likely to heave but will also most likely settle back to its normal elevation again.  However, your concrete is susceptible to cracking during the frost heave event.  Cracking related to frost heave is not a warranty issue.
 
FINISHES:  Interior surfaces are generally finished smooth (basement floor, garage, sometimes porches and patios).  A smooth finish allows for easy maintenance.  Please be aware that smooth finishes are VERY slippery when wet.  Exterior concrete such as walks and driveways are broom or swirl finished.  A broom finish is less slippery  and designed to be walked upon even when wet.  Stamped surfaces and stained surfaces are sealed to help maintain the beautiful characteristics of the color and design.  The sealer used will cause a slippery surface when wet.  Please view the information provided below regarding the use and importance of sealers.  Additionally, surfaces which are stamped or stained will require maintenance; how frequently is out of our control.
 
 
CUSTOMER CARE:

THE DO NOT'S: 1) Do not drive on "new" concrete for at least 28 days.  2) Do not allow water to drain beneath the slab as this may cause settlement cracks.  3) Do not use salt or other de-icing chemicals on the concrete (This is especially harmful during the first winter).  If at all possible, hose off your car of any street salt before parking on concrete. 4) Do not allow your dog's urine (on your decorative concrete) to cycle through the numerous freeze-thaw cycles during the winter.  Dog urine is extreme acidic and can cause damage to your decorative concrete.  We recommend cleaning it as soon as you witness it. 5) Do not allow fertilizers to come in contact with surface if concrete
  
THE DO’s: 1) Caulk all expansion joints, construction joints, and cracks once between 28 and 60 days after concrete is placed. (maintain this caulk as often as possible, at least annually) 2) Seal concrete with a penetrating sealer that helps prevent against salt between 28 and 60 days after concrete is placed. (Reseal annually)  3) We recommend placing rebar 2’ on center in your concrete(while most cracks are minor, a rebar grid in your concrete in combination with proper caulking and sealing will help to protect your concrete long term) 4) Document your maintainance. In the event of a warranty event dated documentation, of caulking and sealing will be required.

RE-SEALING DECORATIVE CONCRETE: It is important to note that we do not warranty sealer related failures.  Surface maintenance is out of our control as heavy traffic, heavy use and severe weather may and can negatively influence the performance of the sealer.  The care and maintenance of decorative concrete is the homeowner's sole responsibility. The frequency with which you should reseal your concrete will depend on the area’s exposure to cars, foot traffic, and any chemicals the decorative concrete is exposed to such as chlorine, salt water, stabilizer and the like.  We highly recommend that stamped concrete projects be kept clean and resealed every other year or as needed.  The longer you wait, the more likely you may notice the surface color fade slightly.  Keeping a fresh coat of sealer will protect and keep the color as vibrant as the day it was installed.  However, keep in mind, too much sealer can cause a host of other problems, the most common is whitening.
  
THE RESEALING TEST:  To determine if you need to reseal you concrete, sprinkle water on the concrete surface.  If the water is absorbed and makes the surface noticeably darker, the sealer has worn off and resealing the project will restore its original beauty.  If the water is not absorbed and beads on the surface, the concrete should still be protected and likely does not require additional resealing.
  
You may contact us to discuss a reseal for your concrete or to purchase sealer directly from us.
