BuildBlock Flat Wall Engineering Manual: Above & Below Grade ICF Walls, Rebar Reinforcement, and Safe Room Design
The BuildBlock Engineering Manual extends prescriptive and safe room engineering for greater wall heights above and below grade as well as making it easier to design FEMA 361 compliant safe rooms. The BuildBlock ICF Products & Safe Room Engineering Manual increases the scope of prescriptive engineering for BuildBlock ICF products. This document is intended to be used in conjunction with the PCA 100 Prescriptive Design of Exterior Concrete Walls for One- and Two-Family Dwellings when determining reinforcement for residential walls and as a reference for commercial engineering.
- Below grade wall include 12ft heights for all products and 14ft in certain applications.
- Maximum above grade wall heights are engineered to 14ft for all products and 20ft in certain applications, reducing the need for site specific engineering.
- Easy to read lintel design tables are based on opening sizes and provide clear reinforcement requirements.
- FEMA 361 & ICC 500-2014 compliant prescriptive design for safe rooms with spans up to 22ft, wall lengths up to 44ft, and wall heights up to 20ft.
- Rebar conversion tables to convert between single and double bar applications.
- The IRC, the PCA 100, the Prescriptive Method, and ACI-318 are recommended companions to this engineering manual.

BuildDeck Design, Engineering and Installation Manual
The BuildDeck Floor & Roofing Decking System is a lightweight, stay-in-place Insulating Concrete Form (ICF) made of Expanded Polystyrene (EPS) and used to construct a solid monolithic insulating concrete floor and/or roof decking system. BuildDeck is perfect for site-cast or precast concrete floors, roofs, decks, and walls for commercial, industrial and residential uses. BuildDeck provides structural integrity through reinforced concrete while providing comfort and sound mitigation through superior EPS insulation.

BuildBlock ICF Swimming Pool Engineering
The BuildBlock ICF Swimming Pool Engineering Manual is intended to provide prescriptive requirements for the design of BuildBlock Building Systems ICF In-Ground and Above Ground reinforced concrete Swimming Pools for limited scope and applications. It provides wall, footing, and reinforcement designs for building above ground and in-ground ICF pools, cisterns, and water basins. This guide provides recommended designs for a variety of soil and seismic conditions.
Additional information about the construction, finish, and accessory products for pools will be forthcoming.
HUD Prescriptive Engineering
The Prescriptive Method published by the Department of Housing and Urban Development is included below and was adopted into the International Residential Code (IRC) and International Building Code (IBC) and contains universally accepted engineering for residential structures.
