What To Know Before Your Derksen Arrives
Be prepared for your building delivery. There are some things that must be provided by the customer prior to free delivery:
Solid Concrete Pad Blocks are recommended for setting up and leveling your building, and cinder blocks can be used in conjunction for extra height (solid blocks on bottom). Ask your delivery driver how many blocks will be needed for your building’s width and length and the leveling requirements of your specific site. Standard solid blocks are 4x8x16”.
For larger buildings, 4x16x16” solid blocks may be needed. Delivery driver will provide treated lumber for leveling and shimming of building if concrete pad blocks are not provided.
Site Preparation is the sole responsibility of the purchaser. Ground should be clearly accessible, clean, dry and firm. Openings through fences or around obstacles should be at least 3’ wider than your building, with enough clearance to make necessary turns. Site should be clear of low hanging limbs, wires, or other obstructions up to 18’ high. Delivery driver is not responsible for removal of fences, gates, trees, limbs or any other obstruction.
Contact your local Codes Office to verify regulations regarding outdoor storage buildings. It is the sole responsibility of the purchaser to secure any needed permits, property line information, signed permission to cross properties, HOA permissions, etc. Derksen Buildings is not responsible for any permits, permissions, guidelines or code restraints.
How Many Blocks Do I Need?

Generally, on a level surface, a block will be placed under each skid at the outside edge of each short wall. A block will be placed approximately every 6′ depending on door placement. Blocks will be stacked vertically for leveling. You can estimate the number of blocks needed by knowing the length and width of your building. 8’ – 10’ wide buildings come standard with two skids. 12’ – 16’ wide buildings come standard with four skids. Ask your dealer or delivery driver for more details.
