Pre-Tak & Pre-Tak HD

Next Generation Pressure Sensitive Adhesive HDPE Membrane

Description: Kingfield’s PRE-TAK membranes are the latest generation of pre-applied waterproofing membranes. PRE-TAK membranes consist of a double-layered composite sheet comprised of a thick HDPE film – 46 mil (1.2mm PRE-TAK) or 60 mil (1.5mm PRE-TAK HD) with strong elastic gel pressure sensitive adhesive.

Kingfield PRE-TAK membranes form a unique, integral bond to poured-in-place concrete, preventing both the ingress and lateral migration of water while providing a robust barrier to vapor, water, gas, and chemically laden soils. Concrete is cast directly against the adhesive side of the PRE-TAK membrane, activating Kingfield’s next generation coating and pressure sensitive adhesive to form a continuous and integral watertight seal to the structure.

Installation is efficient and reliable with a manufacturer marked adhesive selvedge allowing for an HDPE-adhesive-HDPE bond at seam overlaps. PRE-TAK delivers superior performance in harsh conditions without the need for specialized equipment, heat, or power. For situations where more seam protection is required (patching, cut edges, roll ends, etc.), Kingfield’s positive side lap seam tape, PRE-TAK TAPE, is used to keep the integral bond intact. PRE-TAK sheet seams are also heatweld capable. Consult manufacturer’s heatweld instructions.

PRE-TAK membranes are applied horizontally over smooth prepared concrete, carton forms, compacted earth, crushed stone substrates, or mud slabs. PRE-TAK can also be vertically applied blindside to permanent formwork, single sided forms, or adjoining structures.

KEY FEATURES

  • Forms a continuous adhesive bond to poured-in-place concrete
  • Easy to apply, fully-adhered, watertight adhesive seams
  • Provides a barrier to water, moisture, gas, and vapor
  • Prevents lateral water migration
  • Chemical resistant – effective in most types of soils, including brownfields and hydrocarbon-laden soils
  • Weather resistant – Rain and ponding water will not prematurely activate the membrane

ADVANTAGES

  • Durable HDPE withstands puncture and tearing
  • Double width rolls reduces seams and reduces labor.
  • Can be applied to blindside/permanent formwork – allows maximum use of confined and zero-lot-line sites
  • Self protecting – can be trafficked immediately after application for follow-on trade work
  • Heat weld capable for unsurpassed watertight seam performance
