Site Preparation and Platform Construction
Materials NOT supplied with Shed Kit
Important:
• Site preparation is required for this shed. Placing the shed on a properly constructed, square, flat, smooth
and level foundation, as described below, is required. Without a properly constructed foundation, settling
will eventually occur, causing distortion and damage to the shed. Suncast is not responsible for replacing
parts damaged or property lost due to incorrect foundation construction or improper assembly. Warranty
requires a properly constructed foundation to which the shed must be anchored as instructed below.
• Complete the site preparation and foundation construction before unpacking parts and beginning
assembly. For tips on site preparation, go to www.suncast.com, consult retailer, or local code.
Site Preparation
1. Consult your local authorities for building codes and covenants before beginning foundation or erecting shed.
2. Before any digging, check with local utilities to determine location of buried cables, pipes, etc.
3. Decide which type of foundation is most suitable for your installation. The foundation surface must be square, flat, smooth and level.
Follow the below guidelines for foundation options.
4. Complete the foundation preparations as follows:
• A vapor barrier may be applied over the foundation to prevent excessive condensation in the shed.
Follow local building codes for a proper vapor barrier.
• The ground should slope away from the foundation area to provide drainage.
• Placing the shed on surfaces made of materials such as patio blocks or pavers is not acceptable for long-term support structure or
smooth surface. Use of these will void the warranty.
Concrete Slab Wood Platform
• Construct a slab of at least 4” thickness.
• The use of reinforcement bar is recommended.
• For foundations larger than specified below, the shed must rest on a
continuous, level portion of the concrete slab
• Use exterior grade wood.
• Set the wood platform on deck footing blocks
or full footing.
* Dimensions shown are minimal for proper fit of the shed.
Anchoring the Floor Panels to the Foundation is required
after shed assembly is complete.
• Shed floor panels include flattened areas where anchors or lag screws are to be secured. These flat areas
must be drilled through prior to securing the floor panels to the foundation.
Anchor section example
• The shed must be secured to a continuous concrete slab using
3/8" masonry anchors with 1" washers (hardware not included).
8 masonry anchors are required for the Suncast BMS7705 Shed.
• The shed must be secured to a wood platform using 1/4”-3/8" x 3”
lag screws with 1" washers (hardware not included). 8 lag screws
are required for the Suncast BMS7705 Shed.
Note: Shed floor fastening locations are designed to align with
the under-structure layout. Be sure the front of the floor panels are
oriented correctly on the platform to ensure lag bolts engage with
the under-structure.
