Warranty & Care

 Warranty & Care Information

1.) Your concrete will begin to harden in the next 4-6 hours. Although it may seem to be cured, it is not. Concrete takes 28 days to fully cure and realize 100% of its potential strength. However the next 48 hours are the most critical. Your edging will remain very brittle and can easily crumble or break during this time frame. Keep pets, children, service people, and objects completely off of, and away from the edging for the next 48 hours.

2.) Landscape work, sod laying and mulching can begin as early as 7-10 days. Caution must be taken as picks, shovels, and other garden tools can easily damage the uncured concrete. The front bracket of wheelbarrows can easily scratch or chip the edging if the tire is on the curb while dumping. Drive over the edging then dump inside the bed to avoid damage.

3.) If you have a landscape contractor working for you, caution him about protecting the curb from damage. If dirt, rock, mulch or heavy plants must be wheel barrowed over the edging repeatedly, build a plywood ramp to distribute the weight and lay old carpet over to protect the edging from abrasion. Never allow heavy vehicles or tractors to drive over the edging.

4.) You may run the wheels of your lawnmower on the edge once it has cured. Note, however, that if mower decks or other hard objects scrape along the concrete, the concrete may be scratched. Wait at least 2 weeks to weed eat the concrete.

5.) Your edging has been sprayed with 2 coats of commercial grade acrylic concrete sealer. The high-gloss sheen will dull to a semi-gloss with time and weathering. Once the sealer has dried (typically within an hour), light rain will not affect the concrete.

6.) Do not turn sprinkler systems back on for at least 48 hours. The concentrated pressure washer effect of a sprinkler head can etch or leave lines in uncured concrete. Occasionally hard water will produce efflorescence (white powdery appearance) on the concrete. These are mineral deposits. Should efflorescence appear, mix white vinegar 50/50 with tap water and lightly brush the surface to remove.

7.) If Roundup® was sprayed on grass in new beds, it is preferable that those areas remain dry for the next 8 hours. It may take 10-14 days for the grass to completely die. Be patient. A 2nd application may be required to touch up areas not dying out and is not included. Mulching can begin after 7 days and will help to kill the grass. There is no need to remove the dead grass as it will simply decompose into soil underneath the new mulch.

8.) Your edging will appear splotchy and discolored over the next few weeks. This is a natural part of the curing process as moisture dries out of the concrete. Ultimately, the color will dry a few shades lighter than today but may darken again temporarily when it is wet. Due to the use of natural materials and variables beyond our control, actual concrete color may differ from color charts, samples or previously installed projects and is not guaranteed.

9.) All gutter downspouts and sump pump piping should be directed over or under the edging and into the yard. High concentrations of water run-off into landscape beds can cause foundation problems, erosion and unstable ground shift around the edging resulting in cracking. Conversely, drought can be equally damaging. Keep lawns watered to minimize ground shrinkage due to expansive clay soils found in our region. Your edging can separate or crack under extreme drought conditions and will not be covered under warranty. Installation of cable reinforcement will all but eliminate this issue; however, extreme forces can still prevail.

10.) Concrete edging, like any other type of concrete, can and will crack under certain conditions. We experience very little cracking in our products due to prevention techniques. However, it is possible that you will experience some cracking in your concrete edging over time. Cracks are not repairable or warranted and the only remedy is a costly tear out and replacement. It is impossible to get an exact color match and visibly, the “cure is worse than the ill”. Should a crack occur, attempt to determine the cause. The most likely cause will be ground shift or settling, often caused by drainage issues, or a tree root growing up from below. If the concrete is lifting a tree root is the issue and should be cut.  Cable reinforcement (line 11) is the best preventative to mitigate crack expansion.  

11.) Cable reinforcement does not eliminate cracking, however, when installed, cable greatly reduces the effects of cracking by eliminating the ability of the crack to open up or shift. There is a limit to the strength of cable. If enough force is applied, cable can fail resulting in separation.

12.) There may be a void in front of the edging where the sod has been removed. This is normal. Although not mandatory (the grass will grow back naturally) you may want to replace a small amount of topsoil back into this void and re-seed.

13.) The only maintenance your edging requires is periodic re-sealing. We recommend re-sealing once after the first year, then every third year to maintain concrete in the best possible condition. We can provide this service for a very reasonable fee. *See surface warranty below.

Your edging will be undamaged at the time we leave it in your custody. If the edging becomes damaged after we leave, we will return to fix the issue. However, there will be a minimum charge for the first hour, plus materials, to return in the ¾ ton service truck. If the solution requires a full crew and installation truck, a quote will be provided in advance and shall not be less than 50% of our current project minimum + materials, payable in advance. Due to the time and resources required repairs are ridiculously expensive. PLEASE TAKE PROPER STEPS TO PREVENT PROBLEMS FROM OCCURING!


TEN (10) YEAR LIMITED WARRANTY (Effective 2009): MATERIALS AND WORKMANSHIP ARE GUARANTEED FOR TEN (10) YEARS FROM DATE OF INSTALLATION: Defective product will be repaired or replaced at no charge if the defect is caused by the materials we’ve used or the way it was installed by our crew. Although problems are rare, concrete edging can and will crack when subjected to excessive ground movement. The SHARPER EDGE® does not guarantee or imply otherwise. Occasional cracking is expected and will not be replaced under this warranty. This warranty expressly excludes damage due to rust, ice melt, salts, fertilizer or other chemical damage, vandalism, tree roots, excessive ground movement, separation due to drought, neglect or abuse. Warranty will apply to all projects which are inspected and re-sealed by The SHARPER EDGE® one (1) year after install, and at a minimum every third year thereafter. Failure to re-seal on schedule voids warranty. Damage from impact, abrasion, efflorescence, stains or discoloration is specifically not covered under this warranty. At our discretion, concrete which exhibits spalling, flaking, crumbling or other issues due to weathering or material issues will be replaced at no charge within five (5) years of installation and fifty percent (50%) of the current cost in years five (5) thru ten (10). Current project minimums will apply. The published version of this document on our website is the most current version and shall supersede all printed materials.
