Delivery Information
TerraBay Materials delivers bulk landscape and construction materials directly to homes and job sites across Marin, Contra Costa, Alameda, and surrounding Bay Area communities. Whether you are ordering topsoil, road base, drain rock, decorative gravel, decomposed granite, mulch, or sand, this guide explains scheduling, delivery charges, truck access, and how to prepare for your order.
We are a delivery-only supplier with no public walk-in yard. Delivery availability depends on your address, material, order quantity, and safe truck access.
Where We Deliver
Our primary delivery areas are Marin County, Contra Costa County, and Alameda County. We also serve Sonoma County, San Mateo County, San Francisco, and select areas of Solano County. Check our delivery areas or contact us with your ZIP code to review coverage for your location.
How to Place Your Order
-
Choose your material. Review the product description, size options, and ordering unit.
-
Check your quantity. Materials may be sold by the cubic yard or ton. Minimum quantities vary by product.
-
Review delivery access. Contact us before ordering if your property has steep grades, narrow roads, tight turns, or overhead obstructions.
-
Order online or request a quote. Review delivery charges and applicable taxes at checkout. For larger projects or several materials, contact us for help coordinating your order.
Delivery Scheduling & Lead Times
Most standard orders are delivered within 1–2 business days, depending on material availability, delivery location, and truck scheduling. Busy periods, weather, and road conditions may affect timing. Some specialty materials and blends require longer lead times. Check the individual product page and contact us about availability before planning a time-sensitive project.
Need a Specific Delivery Date?
Contact us before ordering if your project requires delivery on a particular day. Requested dates and times are subject to confirmation.
Changes to Your Delivery Plans
If your address, material quantity, or site conditions change after ordering, contact us as soon as possible. Changes may affect pricing, truck requirements, and scheduling. Include your order number when contacting us.
Delivery Charges & Pricing
Delivery charges depend on your address, material type, order quantity, truck size, and route. Review the delivery charge and applicable taxes at checkout before placing your order.
Difficult Access
Steep hills, narrow or winding roads, tight turns, and limited unloading space may require additional planning or delivery charges. Some locations may be unsuitable for dump truck delivery. Send us photos and access details before ordering if your property has challenging conditions.
Larger Orders & Multiple Truckloads
Larger quantities may require more than one load. For a quote, provide your delivery address, material names, quantities, preferred timeframe, and any known access restrictions.
Delivery Trucks & Load Sizes
Smaller dump trucks are available for many residential deliveries, while larger trucks or multiple loads can serve higher-volume projects.
The amount carried per load depends on the material’s density, truck capacity, legal payload limits, and site access. Gravel, sand, soil, and mulch can have very different weights, so the same quantity may require different delivery arrangements. Contact us if you need to review truck dimensions or access before ordering.
Ordering More Than One Material
Different materials may require separate loads and separate checkout orders. Contact us before ordering several products so we can confirm the load arrangement, quantities, and delivery charges. Combining products in an order does not automatically mean they can share one truckload.
Dump Truck Access & Unloading Requirements
Your property must have a safe route for the loaded truck and a suitable place to unload. Please review both before ordering.
Roads, Driveways & Gates
The truck needs enough room to enter, turn, reach the unloading area, and exit safely. Tell us about narrow roads, sharp turns, steep slopes, gates, bridges, and posted vehicle weight restrictions. Required clearances vary by truck and route. A gate width alone does not confirm that a truck can safely reach the unloading location.
Flat, Firm Ground
Choose a flat, firm unloading area that can support a loaded dump truck. Soft soil, wet ground, unstable edges, weak paving, and sloped unloading areas may prevent safe delivery. Tell us about septic systems, underground structures, irrigation equipment, or other areas that trucks must avoid.
Overhead Clearance
Check for power lines, tree branches, building overhangs, and other obstructions along the access route and above the unloading area. A raised dump body requires more overhead space than a truck in its driving position. If wires or other obstructions are near your proposed unloading location, contact us before ordering so we can review an alternative.
Final Safety Assessment
Photos and measurements help us plan, but the driver must assess actual conditions on arrival. Delivery or unloading may be declined if the location is unsafe. An alternative unloading spot, rescheduling, or cancellation may be necessary.
Prepare for Your Delivery
Before the truck arrives:
-
Choose your unloading spot. Leave enough room for the truck and the material pile.
-
Clear the access route. Move parked vehicles, trailers, bins, and other obstacles.
-
Arrange gate access. Make sure any gates or access restrictions have been discussed with us.
-
Identify areas to avoid. Tell us about weak surfaces, underground structures, and sensitive landscaping.
-
Keep your phone available. Make sure you or your site contact can be reached about the delivery.
-
Keep the unloading area clear. Children, pets, and bystanders must stay away from the truck and material discharge area.
If you would like material unloaded onto a tarp, discuss the location with us beforehand. A tarp can help contain the pile, but some spill-over is expected based upon material, access and quantity.
What to Expect on Delivery Day
The driver will review access and the proposed unloading spot before dumping. If you have a concern about the material or quantity, raise it before unloading begins. Standard bulk delivery leaves material in a pile at one accessible, agreed location per load. Plan for you or your contractor to move, spread, grade, or install the material afterward. The driver determines whether unloading can proceed safely. Please keep clear of the truck while it is maneuvering, raising the dump body, and unloading.
