Will my yard be damaged during installation?2023-03-17T16:08:20+00:00

If you have existing grass it will not be effected by our machines. The grass in the areas the curb will be laid is sod cut and a 12-inch swathe of sod is removed. Outside that area the grass remains the same. We transfer the concrete using a Piledriver/wheelbarrow, which have large turf tires and don’t tear up the grass.

Do you have any issues with cracking in your curbing?2023-03-17T16:09:11+00:00

We use 1/8th inch Galvanized Cable in all our curbing. This will help keep the curb together at the control joints and at any cracks that may occur. Curbing is a concrete product and if a curbing company says their curbing never cracks they are simply not telling the truth. We have very minimal cracks as we use the correct ratios and techniques when it comes to mixing concrete and finishing. Spider cracks can occur in concrete and must not be mixed up with separation. You must remember that cracks can and will occur in concrete. Many factors contribute to this including materials, layouts, and temps. The main issues with landscape curbing are extreme angles, inclines, and declines. You must realize that a curbing machine weighs approx. 210 lbs. so getting enough compression is extremely difficult in these situations. Cracks are concrete issues, they can and will happen. Cracks that are over 1/4 wide on level ground are an issue with operator error or lack of compaction, these cracks will be covered under warranty. Cracks in all other situations are not. We put the control joints closer to relieve stress, but cracks can occur, they are a fact of concrete life. We are dealing with moving concrete.

What kind of options do I have when it comes to decorative curbing?2023-03-17T16:09:37+00:00

You have several options with curbing. There are many different sizes, styles, and shapes. Curb can be colored and or colored and stamped. We offer Smooth finish(no stamp), Roller Patterns, Handstamp Deep Impressions. Curbing can also be made to look like stone with our new carving techniques. Multi-colored with different antique releases.

What about reinforcement and p.s.i.?2023-03-17T16:10:14+00:00

Landscape curbing is just that, for your landscape. You need to keep this in mind and not compare it to curb you see in a parking lot. It isn’t the same as it doesn’t have the same aggregate. PSI for normal landscape curb varies on the type of sands used and ratios mixed. Most are in the 2000 psi range. You can do several things when it comes to reinforcement. Rebar like in flatwork is used for specific situations, for Lateral Reinforcement. As mentioned previously, we use cable in our curb as that may help with separation, which is tensile strength. We also use blended polymers and fiber which not only increase tensile strength but compression strength as well.

I have an existing yard can I still have curbing put in?2023-03-17T16:10:45+00:00

If your yard has existing grass and sprinklers you can have curb put in. There are a couple things to be aware of though. Existing yards are considered a retro-fit, done after the fact. Normally curb goes in before the sprinklers and rock or mulch so the curbers can create smooth flowing lines without obstruction like sprinkler heads ect. Since they are already in along with the plastic or brick edging, the curb may go outside those areas and create new lines. Curb can easily be placed outside the sprinkler heads and not obstruct spray that way we can create smooth, beautiful flowing lines. The space behind the curbing then can be filled with your material.

Can you help us with layout?2023-03-17T16:11:23+00:00

For sure! Smooth flowing lines and curves are the very best look you can get. Straight lines and corners aren’t as aesthetically pleasing as flowing curves. You also can’t get proper drainage with them. Realize that a 210 lb machine is laying your curb, it’s constantly moving so straight lines will NEVER be absolutely straight even when following a string line. You want the curb around your house to flow so it’s easy to mow and you don’t have to stop. You want it to transition cleanly to the next. Flow is extremely important and it’s the first thing you see when someone drives by.

What kind of warranty can I expect for this type of product?2023-03-17T16:11:53+00:00

Our warranty on curbing is a 2 years workmanship warranty. Because this type of concrete cures so fast any issues you will have will commonly occur in the first 24 hours. Spider cracks are a concrete issue that can and may occur. Do we ever have issues with them? NO, but you need to be aware. If a crack forms and it’s more than a 1/4-inch-wide, it is operator error and will be fixed. Cracks that occur due to vehicles, heavy mowers, natural occurrences such as tree roots, ground heaving, etc. will not. Common sense really comes into play, when a car drives on landscape curb it’s prob not going to hold up. It mainly depends on the ground underneath. Spider Cracks are a fact of life in concrete and may occur in certain situations.

I’ve scheduled curbing to be put in, what should I do before the crew shows up?2023-03-17T16:12:39+00:00

All sprinklers need to be marked either with a flag or paint. When we cut the sod, we use a sod cutter that will cut your sprinkler in half. We aren’t responsible for sprinklers ruined if they aren’t marked. Make sure your driveway or area on street is clear of vehicles so we have room to park.

What do i do with sprinklers? On new properties and existing ones?2023-03-17T16:13:45+00:00

If you have a new construction and are looking to have curbing put in, the sprinklers go in after the curb. Most sprinkler companies who work with us want it this way and so do we. It’s easier for both of us. If you have the sprinklers in first then they dictate where the curb goes, this makes for not smooth flowing lines because we must adjust to them. In the opposite sense, the sprinkler guys can put their heads next to the curb when it’s in first.

On existing lawns, 90% of the time we will go outside your heads to create nice lines. No worries, your heads will shoot over the curb and spray normally. We can also move a couple of heads if needed, a service charge of $15 per head is applied.

Are there any sealers that are applied and do i need to reapply after?2023-03-17T16:14:17+00:00

A high gloss acrylic sealer is sprayed on all curb that has color. Stamped or not. This is the only thing that brings the color out and makes it pop. Liken it to a clear you put on wood to see the grains. Water based sealers DO NOT work as well, make sure it is not used on your curb. All sealers regardless of what they are will need to be reapplied. Sealer that is exposed to sunlight and UV rays will break down over time, this doesn’t mean they will peel off or disappear. They will lose their luster and need to be re-emulsified. Another coat will darken all your colors like the first time and make it look nice again. This is part of Maintaining Decorative concrete.

Do you do anything to protect our house from water issues?2023-03-17T16:18:23+00:00

This is a huge issue that MUST be addressed. We don’t care if you choose Borderline Designs to do your curbing, you must make sure the company you hire takes care of drainage. Every area that may hold water gets a small “v” cut in the concrete to let water out. It is a 4-inch concrete dam and it will hold water. Therefore, when you do long waves and curves you can manipulate drainage. Water will settle at the bottom of a curve, it’s an easy place to place a drain.

Roof Gutter Downspouts are diverted to the grass side of the border using a 4in corrugated pipe and emitter.

Is there a minimum footage for a job?2023-03-17T16:18:58+00:00

Yes, we have a minimum footage. You must realize that a normal curbing crew is 3-4 men, with 1 truck and a trailer with all the necessary equipment. We cannot travel across town and do 20 feet, a company would lose money on that. We currently have a 100 foot minimum on New Installs, some other companies are lower but may have a smaller crew etc. Tree rings need to be large enough to handle growth years down the road and they are difficult and time consuming. We have a 20-foot minimum on tree rings which will give you at least a 6 foot diameter circle.

Will you move the rock and remove our old edging?2023-03-17T16:19:44+00:00

Anything related to removing old edging so your new curbing can be installed, will be taken care of. This will be included in the estimate. Whatever you can do before we arrive is greatly appreciated.

Do you have a minimum footage or cost?2023-03-17T16:20:12+00:00

We have a $500 minimum for any Non-Curb Install or Curb Repair we do.

What if the curb get damaged? Will you come an fix it?2023-03-17T16:20:59+00:00

As stated in the previous question we have a $500 minimum for a property. If you run over your curb with a skid steer, or someone stepped on it after install it’s the same. We must bring the same equipment and same crew to do 10 feet as we would for 500 feet.
