UNDERSLAB WATERPROOFING WITH INSECT BARRIER

************************************************************************************************************************

This guide specification has been prepared by Polyguard Products Inc., in printed and electronic media, as an aid to specifiers in preparing written construction documents for Underslab insect barrier and waterproofing membrane systems. Polyguard® TERM™ Underslab Barrier is used as a waterproofing membrane/vapor barrier to virtually eliminate water and vapor transmission through concrete slabs on grade. In addition to protecting floor finishes and indoor air quality, TERM™ Underslab Barrier also acts as a barrier to insects, pesticides, methane gas and radon gas.

PART 3 EXECUTION

3.01EXAMINATION

A.Examine surfaces to receive membrane. Notify General Contractor if surfaces are not acceptable. Do not begin surface preparation or application until unacceptable conditions have been corrected.

3.02SURFACE PREPARATION

A.Protect adjacent surfaces not designated to receive waterproofing and insect barrier.

B. Prepare surfaces to receive waterproofing and insect barrier in accordance with manufacturer's instructions.

3.03APPLICATION

A.Horizontal Application shall be in accordance with manufacturer’s instructions and ASTM E 1634-98.

  1. Unroll barrier membrane with longest dimension parallel with direction of pour.
  1. Place high strength polyethylene backing to the soil underneath and fabric on top.
  1. Lap waterproofing barrier membrane over footings and seal to foundation walls.
  1. Overlap side seams using the maximum 4" edge trim seal. If polyethylene backing has become dirty, clean its surface with 30% Isopropyl Alcohol prior to application on the 4" edge seal.
  1. End laps should be overlapped a minimum of 4" and addressed by applying a coat of liquid adhesive or sealant approximately 150-200 sq. ft. per gallon to fabric side of barrier membrane and placing adjacent sheet on top.
  1. After application of end lap use liquid adhesive or sealant to prepare seam and apply a 12" piece of UV resistant barrier tape centered over seam to seal extend out 6” past side laps.
  1. Roll side seams and end laps with a minimum 75 lb. steel roller to assure full adhesion.
  1. For penetrations – waterproofing:

a. Apply liquid adhesive or sealant a minimum of 4” out from penetrations.

b. Install Polyguard FastPitch™ around penetrations, with a minimum of 4” between all penetrations and the collar.

c. Push up any sleeves on penetrations from the portion of the penetration where the pourable LM85 sealant and TERM Penetration Barrier Sealant will be applied (minimum of 3” up)

d. Penetrations should have a clean surface (wire brush or sand) before pourable sealant is applied.

e. Apply LM 85 Self Leveling Sealant at all penetrations extending a minimum of 4” onto underslab barrier membrane, and 2” in depth, completely filling the FastPitch collar.

f. Allow LM 85 to cure until solid (30 minutes to 2 hours depending on conditions.

  1. For penetrations – TERM Penetration Barrier (this step must be performed by a Polyguard approved pest control applicator:

a. Apply minimum ½” width bead on gunnable TERM Penetration Barrier around the neck of each penetration.

  1. Steel reinforcements will be applied directly over the barrier membrane. It is of utmost importance that reinforcement (rebar) chairs that are used are compatible with the system. Steel chairs and bolsters should be plastic dipped or have plastic caps.
  1. Precaution should be taken to protect the barrier membrane during placement of reinforcing or concrete. 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 the liquid adhesive at a rate of 150-200 sq. ft. per gallon to fabric side of waterproofing barrier membrane and apply a patch of fabric tape.
  1. Prior to slab pour all standing water must be removed from the membrane.
