36 <br /> wallform web is present is preferable as you can penetrate deep into the wallform at that point J <br /> using 3.5-4"screws. . Do not install fasteners with tight-torque tools that might"strip-out"the <br /> fastener hole. <br /> Pneumatic nail guns have been used successfully to attach light weight dimensional lumber. The <br /> key concerns are that cement coated nails must be used, and that two nails are driven in at right <br /> angles to one another. This technique creates a locking design that sufficiently resists pullout. <br /> Light-weight objects can be successfully fastened directly to the Wallform. <br /> 11.0 Below Grade Surface Treatments of Bewail®Wallforms <br /> Below grade wall surfaces outside of living space must be parge coated and waterproofed. <br /> For some applications without living space inside, such as frost foundations,a parge coating is <br /> sufficient when used in conjunction with an adequate drainage system. <br /> Equally important to the effectiveness of any waterproofing system is adequate drainage. There <br /> are several products available to provide"in-plane"drainage throughout the full height of the <br /> basement wall.These, coupled with properly designed footing drains,will take the water away <br /> before it has the chance to become a problem. <br /> 11.1 Recommended Below Grade Damp Proofing Protocol <br /> The goal for below grade applications is to effectively stop water transmission but allow for <br /> water vapor permeability through the wall forms. <br /> 11.1.1 Steps <br /> I. Apply a parge coat of 3 parts sand to one part Portland cement directly to wallforms to <br /> close any gaps between each. <br /> 2. Apply a waterproof coating over the parge coat(Ex;Thoroseal, Tamoseal, or Xypex) <br /> 3. Apply a dimple shield membrane(Ex; MiraDrain) <br /> If not applying a dimple shield membrane then it is necessary to provide a bed of stone between <br /> the earth and the wall(16 inches minimum is recommended). In some soil conditions builders <br /> use both a dimple shield membrane and a crushed stone bather. <br /> shelterWorks General Application and Technical Information(GATT)version 2.5 <br />
