How Does the Design & Installation Process Work?
Listen to landscape designer Lonny as he walks you through the design process:
How tall can I build a wall?
There appears to be no limit on the height of walls that can be built using segmental retaining wall systems provided that the wall is properly designed and constructed with appropriate soil-reinforcement materials. Requirements and construction technique will vary with height and site and soil conditions.
Can pavers be glued over concrete?
may be glued over existing concrete using a special adhesive known as
. Avoid gluing pavers in ground level applications such as
driveways, walks or patios as the existing concrete may not be of
sufficient quality. Also, gluing in these situations nullifies the
ability of the paver surface to adjust with movement during the
freeze-thaw cycle. Pavers are most successfully glued in applications
using retaining wall units such as stairways and elevated patios.
should be used as ordinary construction adhesive will
not provide a bond that is both strong and flexible.
At what temperature can concrete adhesive be used?
Concrete adhesive should be used above freezing temperature. Make sure the surface is clean and dry before application.
How thick a base is required for patios? Driveways?
4" to 6" of base is required for foot traffic (patios, walkways, etc.)
and 10" to 12" is needed for driveways and other applications for
vehicle use. Exactly how much a particular project will require will
depend on use, as well as site and soil conditions. The sand setting bed
should be 1" thick.
Is a base really necessary?
An appropriate base is needed for both retaining wall and paver
applications. It provides a sound structural foundation to bear the
weight of the project, while resisting moisture and the effects of
movement from the freeze-thaw cycles.
Do I need drain rock, tile or fabric behind my retaining wall?
some small garden or planter walls, drain rock will not be needed.
Otherwise a drainfield of 3/4" clear, angular aggregate will be needed.
The size and location of this drainfield, as well as the location of
geotextile fabric, if used, will vary from project to project.
What questions should I ask my landscape contractor?
Q: How long have you been in business?
Tip: Look for a company with an established business history in your community.
Villa: Villa has been in business for more than 30 years.
Q: How many employees does your company have?
Tip: A year-round staff indicates a stable, credible company.
Villa: Although our installers work seasonally, Villa's professional staff of landscape designers is available year-round for consultation, estimating and design work. Don’t hesitate to contact us any time with your questions or concerns.
Q: Can you provide a list of references for projects you have done?
Tip: A contractor should be able to supply you with a minimum of three references.
Villa: Each Villa designer has a list of five references.
Q: Are you insured and covered by workers compensation?
Tip: You can ask for copies of the insurance certificates to verify coverage of your contractor.
Villa: We have current copies of all of our contractors’ insurance certificates on file.
Q: Does your company provide a written warranty?
Tip: A reputable company should warranty its work and material that is installed.
Villa: Villa Landscapes provides a two-year written warranty on material and services and a one-year replacement warranty on plant materials.
Q: Is your company a full-service or specialty firm?
Tip: If you’re planning on replacing a fence or building a gazebo, you might be better off hiring a fence installer or a carpenter. However, if your project involves multiple aspects, consult a full-service or design-build firm.
Villa: Villa landscapes is a full-service design-build firm specializing in hardscapes.
Q: Will we need a permit for this project?
Tip: A qualified contractor will be knowledgeable about the local permit process and whether it applies to your project.
Villa: Your Villa designer will make sure all permits are obtained and underground utilities located before any work is done on the property.
Q: Who will be assigned as project supervisor for the job?
Tip: Get names and contact phone numbers for all persons who will be involved with your project.
Villa: Villa Field Supervisor Greg Smedstad oversees each project along with the designer.
Q: When can you start?
Tip: Find out what time of day their crews will start and finish.
Villa: Our lead time varies during the season anywhere from three to five weeks. Our crews will start between 7 a.m. and 8 a.m. and end between 3 p.m. and 4 p.m.
Q: When will you finish?
Tip: If you have specific events or deadlines to meet, make sure that is in the contract.
Villa: An average job will take 2 to 3 days; some more complex jobs can take up to 2 to 3 weeks. Once we start a job, we will stay on it until it is completed. The designer will contact you about delays or changes in the schedule.
