3.2	SURFACE PREPARATION
A.	Protect adjacent surfaces not designated to receive waterproofing and termite barrier.
B.	Prepare surfaces to receive waterproofing and termite barrier in accordance with manufacturer's instructions.
C.	Surface of base must be free of standing water.
3.3	APPLICATION
A.	Horizontal Application: In accordance with manufacturer's instructions.
B.	Install Underslab Barrier Membrane when temperatures are 40 degrees F (4 degrees C) and rising.
1.	Unroll barrier membrane with longest dimension parallel with direction of pour.
2.	Place high strength polyethylene backing to the soil underneath and fabric on top.
3.	Apply required preformed inside and outside corner boots prior to application of membrane following manufacturer's details and specifications.
4.	Lap waterproofing barrier membrane over footings and seal to foundation walls.
5.	Overlap Side Seams: Use the maximum 4 inch (102 mm) edge trim seal. 
a.	If polyethylene backing has become dirty, clean its surface with 30 percent Isopropyl Alcohol prior to application on the 4 inch (102 mm) edge seal.
6.	End Laps: Overlap a minimum of 4 inches (102 mm). 
a.	Address by applying a heavy coat of liquid adhesive sealant approximately 50 to 75 sq ft per gallon to fabric side of barrier membrane and placing adjacent sheet over the end lap.
7.	Side Laps: After end lap application use liquid adhesive or sealant to prepare seam and apply a 12 inch (305 mm) piece of underslab fabric tape centered over seam to seal. Extend out 6 inches (152 mm) past side laps.
8.	Roll side seams and end laps with a minimum 75 lbs steel roller with determined pressure to ensure full adhesion.
9.	Penetrations in Waterproofing: 
a.	Apply a heavy coat of liquid adhesive; 50 to 75 sq ft per gallon a minimum of 4 inches (102 mm) out from penetrations.
b.	Install collar around penetration clusters, with a minimum of 4 inch (102 mm) between penetrations and the collar.
c.	Push up any sleeves on penetrations from the portion of the penetration from the level of the slab to a minimum of 3 inches (76 mm) above the slab. 
d.	Penetrations should have a clean surface; wire brushed or sanded, before pourable sealant is applied.
e.	Apply semi self-leveling sealant at penetrations extending a minimum of 4 inches (102 mm) onto underslab waterproofing termite barrier membrane, and 2 inch (51 mm) in depth, completely filling the collar.
f.	Allow pourable sealant to cure until solid; 30 minutes to 2 hours depending on conditions.
10.	Penetrations in Termite Barrier: Apply minimum 1/2 inch(13 mm) width bead of termite sealant barrier around the neck of each penetration.
11.	Steel reinforcements (rebar) will be applied directly over the barrier membrane. 
a.	It is important that reinforcement chairs used are compatible with the system. 
b.	Blocks, pavers or dobies made of concrete or brick are clearly the best choice. 
c.	Individual chairs are acceptable if they have a flat base or bolsters with rails. 
d.	Contact Polyguard Technical Service for approval and written permission for other types of rebar chairs.
12.	Precaution should be taken to protect the barrier membrane during placement of reinforcing or concrete. 
13.	Prior to Concrete Pour:
a.	Visually inspect barrier membrane prior to pouring of concrete for any punctures or damage to membrane which needs to be repaired. Patch any damaged areas by applying a heavy coat of liquid adhesive at a rate of 50 to 75 sq ft per gallon to fabric side of waterproofing barrier membrane and apply a patch of fabric tape.
b.	Prior to slab pour all standing water must be removed from the membrane
c.	It is highly recommended to perform a smoke test under the underslab barrier just before the concrete pour, sealing any area where smoke appears.
