UNDERSLAB WATERPROOFINGWITH NON-CHEMICAL TERMITE 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® UnderslabBarrier 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®UnderslabBarrier also acts as a barrier to insects, pesticides, methane gas and radon gas.

In the Totalflow™ system, the sheet drain performs its normal function of water collection, while the Totalflow™ section provides both water collection and a high-profile section allowing for high-capacity water flow to designated drainage exits.

PART 3EXECUTION

3.01EXAMINATION

A.Examine surfaces to receive membrane. Notify General Contractor if surfaces are notacceptable. 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.

C.Concrete surfaces must be clean, smooth, and dry. Surface of base must be free of standing water.

3.03APPLICATION

A.Horizontal Application shall be in accordance with manufacturer’s instructions.

  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. Apply required preformed inside and outside corner boots prior to application of membrane following manufacturer’s details and specifications
  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 heavy coat of liquid adhesive sealant approximately 50-75 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 TERM Underslab FabricTape 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 with determined pressure to assure full adhesion.
  1. For penetrations – waterproofing:

a.Apply a heavy coat of liquid adhesive (50-75 ft2/gal 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 Semi 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 Sealant Barrier:

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

  1. Steel reinforcements will be applied directly over the barrier membrane. It is important that reinforcement (rebar) chairs used are compatible with the system. Blocks, pavers or dobies made of concrete or brick are clearly the best choice. Individual chairs are acceptable as long as they have a flat base or bolsters with rails. Contact Polyguard Technical Service for approval and written permission for other types of rebar chairs.
  1. Precaution should be taken to protect the barrier membrane during placement of reinforcing or concrete.
  2. Prior to concrete pour:
  1. 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 50-75 sq. ft. per gallon to fabric side of waterproofing barrier membrane and apply a patch of fabric tape.
  2. Prior to slab pour all standing water must be removed from the membrane
  3. It is highly recommended to perform a smoke test under the TERM Underslab Barrier just before the concrete pour.
  1. When pouring concrete, the structural slab must be sound to avoid buckling. It is recommended that concrete be poured within 30 days of the membrane installation. Following proper ACI guidelines, concrete must be placed carefully and consolidated properly to avoid damage to the membrane. Never use a sharp object to consolidate the concrete.
