22 Step 1 Remove Organics

23 What Are Organics Organics are black soil that contains leaves and plant matter that can decompose and settle

24 Establish Building Footprint Pin the building footprint and establish off sets to allow for excavation Remove surface soils to correct elevation to allow for the overall depth of Legalett assembly.

25 Site Preparation A minimum of 4 of clear stone will be required. ** (more stone allows for easier trenching of utilities later). **Refer to Excavation and Skirting Product Data Sheet to determine excavation depth.

26 Excavate With Drainage to Daylight Ensure gravity drainage to daylight ** Do not create a swimming pool effect **

27 Step 2 Place and Level Stone

28 Raising The Grade Build up grade with compacted fill only if required. This can be pit run, sand, A or B gravel or 3 breaker run. Fill must be compacted in 6-12 lifts. (3 minus topped with A shown)

29 Drainage Layer Build up over sub base with ¾ clear stone and level with a Bob Cat or dozer. Extend stone 2 feet outside of building footprint (3/4 clear stone shown)

30 A Stone Slinger Makes it Easy Alternately a stone Slinger can also be used to place the stone.

31 Leveling with 3/8 (10 mm) stone (OPTIONAL) Place 1 2 of pea gravel (3/8 clear stone) on top of the ¾ stone to make final leveling easier Level to +/- ¼ around the perimeter and to within ½ everywhere else using a small vibrating plate packer. If 3/8 stone is not used, level ¾ stone as above.

32 Plumbing and Services Locate and place plumbing risers and all other slab services. - Water, Electric, Gas, etc..

33 Final Leveling Re-level after plumber to within ¼ of desired elevation under edge elements and within ½ everywhere else. Compaction is not required again.

34 Step 3 Install EPS Formwork

35 Begin Placing a Pre-Cut Corner All 90 degree corners come already coped. All other angles will need to be cut on site.

36 Finished Corner Lock the corners together by screwing through overlapped 1 5/8 metal cap.

37 Beginning Edge Element Placement Place edge elements end to end and cap with the metal channel provided Use ¾ screws to lock channels together.

38 Staggered Joints Stagger the joints of the metal caps with those of the edge elements.

80 Drop Down Slab Dedicated heater box for ultimate zone separation between house and garage

81 Alternate Drop Down Slab with Form Support The heating system may run into the garage and a temporary form support is put in place. Vertical support dowels are removed as soon as concrete has started to firm up and the holes are patched.

82 Point Loads up to 100,000 lbs. Point loads up to 100,000 lbs can be accommodated by removing 1 layer of EPS at the required area and inserting a bottom grid of rebar. This will be indicated on the drawings where required

83 Special Applications This foundation for an agricultural Digester replaced a design that called for an 12 x 8 wide footing and 4 concrete floor. It was buried 5 below grade.

84 Weigh Down Box Ensure box is weighted down to prevent floating. Tape lid to box after inspection is complete.

85 Pre-Pour Inspection Complete the Pre- Pour inspection documents. NOTE: This can only be performed by a trained Legalett inspector.

86 Pre Pour Checklist

87 Step 8 Place and Finish Concrete

88 Concrete Placement Place concrete using a pencil vibrator around areas of congestion, heater boxes and doorway cutouts. Concrete must be vibrated to ensure full consolidation.

89 Pumping an 8,000 sq.ft Home Pumping is always recommended unless the slab is small enough to use a conveyor

90 Finishing Concrete Leveling the surface with a vibrating screed helps in the consolidation.

91 Connection Dowels/Anchor Bolts Install rebar dowels as per ICF manufacturers specs around the slab perimeter or 8 anchor bolts for wood framing. Pre plan to ensure anchor bolts do not line up with stud positioning or door ways.

92 Post Concrete Placement Keep top of slab moist for 3 days to minimize shrinkage cracking. This can be done by wetting the slab and tarping or covering with 6 mil poly.

93 Step 9 Preparing for Permanent Heater Installation

94 Vacuum Out the Piping Vacuum any water or debris from the pipes before installing the Legalett Construction Heater.

Install the Construction Heater A 230V 30A breaker should be installed in the hydro panel with a dryer plug terminal end (construction heaters with blue fans).

95 Install the Construction Heater A 230V 30A breaker should be installed in the hydro panel with a dryer plug terminal end (construction heaters with blue fans). Silver-fan construction heaters can either plug into the 3000 series box or a dryer plug. Follow instructions with heater for covering the heater with the box provided to maximize the heating of the slab. Rotation is required for 4000 series heaters

96 Heating the Slab A Legalett construction heater must be run for 2 weeks after the building is closed in and before the permanent heaters are installed. The slab temperature must reach 27 C before installing the permanent heater.

Slab Moisture Test Prior to Installation of insert & floor coverings: Once the surface temperature reaches 27 C and the heater has been run for 2 weeks, tape the supplied

97 Slab Moisture Test Prior to Installation of insert & floor coverings: Once the surface temperature reaches 27 C and the heater has been run for 2 weeks, tape the supplied polyethylene sheet to slab surface for a minimum of 48 hours. No condensation should be present. If condensation is detected, run construction heater for one week and repeat test.

98 Drying The Slab Overall reduction in the moisture content of the slab is required to prepare the surface for floor covering adhesives and to prevent moisture damage to the permanent heaters.

99 Proving Out Hot Water Supply Step 1 Ensure a hot water/glycol supply is installed and operating

100 Proving Out Hot Water Supply Flush out plumbing system: Close the isolation valve at the pump. Then open the flush valve next to pump, and run water through the piping until all debris and air have been flushed out of the lines. Close flush valve, open isolation valve at pump, bleed and energize pump until pump outlet piping is hot.

101 Thermostat Wiring Step 1 Run 3 conductor wiring from box to each thermostat

102 Pre Start-Up Checklist Pre Start up Checklist must be completed by a trained Legalett installer.
