SikaProof®-730 UVS

(former MSeal 730 UVS, SikaProof® SK3000)

PRE-APPLIED FULLY BONDED HDPE WATERPROOFING MEMBRANE FOR BELOW GRADE WATERPROOFING

SikaProof®-730 UVS is an HDPE membrane with unique pressure sensitive adhesive and a state of the arts top film which enable good chemical adhesion with concrete surface.
SikaProof®-730 UVS forms a unique integral seal around the concrete poured against it, prevents water ingress even under high hydrostatic pressure and prevents lateral water migration as well.
SikaProof®-730 UVS remains fully adhered to concrete (i.e. monolithic) helping retain its performance even when there is ground settlement beneath the slabs

  • Fully Adhered to Poured Concrete – Prevents later water migration between concrete and membrane
  • Unaffected by hydrostatic pressure – Can be used in high water table areas
  • Unaffected by Contamination – Does not require any special protection during construction – can be easily cleaned with water and high-pressure air
  • Simple and Easy to Install – Does not require special tools and welding techniques
  • Chemically resistant – Can be used in all soil and sub-soil conditions, even if contaminated with salts.
  • Fully adhered watertight laps – Ensures water tightness.

Usage

SikaProof®-730 UVS is intended for use in below grade waterproofing applications such as basements rafts and confined retaining walls with high water table and cut & cover structures (e.g, tunnels) and allows efficient use of confined sections.

Application

Application steps

SUBSTRATE PREPARATION

It is essential to create a sound and solid substrate to eliminate movement during the concrete pour. Substrates must be regular and smooth with no gaps or voids. Grout around all penetrations for stability.

Horizontal Blinding
The blinding must be free of loose aggregate, voids, surface irregularities and sharp protrusions. The surface needs to be in a touch dry condition. SSD condition (no standing water) is also acceptable

Vertical Surfaces
The vertical surfaces should have proper levelled brickwork, blockwork, or formwork without any irregularities. For the case of sheet piles, the substrate should be made regular with a smooth finished shotcrete or sacrificial formwork to be installed

 

APPLICATION

Pouring of Concrete
Kindly ensure that the plastic liner of the membrane is removed prior to placement of reinforcement. It is recommended that concrete is poured within 5 weeks after the HDPE membrane has been laid on the sub-base (e.g. PCC). Care should be taken to avoid any damage to the membrane during laying steel reinforcement, consolidation, and compaction of concrete.
Additionally, during placement of concrete, the vibrator needle should not touch the placed HDPE membrane.
