A: Kirkwood Material Supply offers full delivery service on all the products we sell. Deliveries start at 8 am with the last delivery being made at 4 pm Monday through Saturday.
A: Kirkwood Material delivery service is considered curbside. Truck weights range from 18,000 to 80,000 pounds plus. Damage to concrete curbs, sidewalks, asphalt, driveways or other objects may occur. Kirkwood Material is not responsible for any damages that occur during delivery. Our disclaimer must be signed authorizing our truck to leave the street. If you sign the disclaimer and instruct our drivers to leave the street and the vehicle becomes stuck, you are responsible for any tow or wrecker service charges that are incurred. Drivers cannot determine whether the truck will cause surface damage to a yard, driveway, sidewalk, curb and other objects. It will be the customer’s responsibility to make the decision. It will be up to the driver to decide if placement of the material can be done in a safe manner. Deliveries onto unpaved surfaced areas after a rain are not permitted. Please reschedule when conditions are totally dry.
A: Generally, 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.
A: 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.
A: For some small decorative walls (planters, garden walls), a thin layer of sand may be sufficient. Generally, however, minus gravel base of an appropriate thickness is required.
A: In some small garden or planter walls, drain rock will not be needed. Otherwise a drainfield of ¾” aggregate will be needed. The size and location of the drainfield, as well as the location of geotextile fabric, if used, will vary from project to project. Generally, you’ll want to avoid using fabric behind the wall. Consult a Kirkwood Material representative with regard to the particulars of a specific project site.
A: 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 soil conditions. Kirkwood Material Supply representatives are available to review the specifics of a given project.
A: Sealing pavers is not required, but sealed pavers do offer some advantages. Sealing helps resist stains and enhances the color of the paver. Sealers however are topical products and must be reapplied regularly – generally every 3 – 5 years.
A: Pavers may be glued over existing concrete using a special adhesive known as paver bond. Avoid gluing pavers in ground level applications such as driveways, walks or patios as the existing concrete may not be 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. Genuine paver bond should be used as an ordinary construction adhesive will not provide a strong, yet flexible bond.
A: Concrete adhesive should be used above freezing temperature. Make sure the surface is clean and dry before the application.
